The exemplary DL subframe structure of Figure 10 diagram in a wireless communication system.
Referring to Figure 10, each subframe can be divided into control area and data area.Control area includes from first
One or more OFDM symbols that OFDM symbol starts.The control zone in subframe can be independently disposed in each subframe
The quantity of OFDM symbol used in domain.Emitted by Physical Control Format Indicator Channel (PCFICH) about OFDM symbol
The information of quantity.BS can emit various control information to one or more UE by control area.Control information is emitted,
Physical downlink control channel (PDCCH), PCFICH and physics can be distributed to control area to mix arq and refer to
Show channel (PHICH).
BS emits and the paging channel (PCH) and downlink chain as transmission channel on PDCCH to each UE or UE group
It shares the associated information of resource allocation of channel (DL-SCH), UL scheduling grant, mix arq (HARQ) letter in road
Breath, downlink allocation index (DAI) etc..
BS can emit the data for UE or UE group by data area.By data area emit data also by
Referred to as user data.Transmitting for user data can distribute physical down link sharing channel to data area
(PDSCH).Emit PCH and DL-SCH by PDSCH.UE can be read by decoding the control information emitted via PDCCH
Take the data emitted by PDSCH.Emitted by PDCCH and is used to indicate which UE or UE group is PDSCH data be launched into
Information and it is used to indicate how UE or UE group should receive the decode the information of PDSCH data.For example it is assumed that using radio
Network Temporary Identifier (RNTI) ' A ' carrys out CRC and shelters specific PDCCH, and is emitted by specific sub-frame about using radio
Resource ' B ' (for example, frequency location) and use transport format information ' C ' are (for example, transmitting block size, modulation scheme, encoded information
Deng) transmitting data information.Then, UE in the cell monitors PDCCH using its RNTI information.With RNTI ' A's '
UE receives PDCCH, and the PDSCH indicated by ' B ' and ' C ' is received by the information of received PDCCH.
Multiple PDCCH can be emitted in control area.UE can monitor multiple PDCCH to detect its PDCCH.By

(CRC).CRC is sheltered using the unique identifier of each UE, each UE is enabled to receive its PDCCH.However,
Because UE does not know the position that its PDCCH is launched into substantially, it requires UE for corresponding in each subframe
All PDCCH of DCI format execute blind Detecting (also referred to as blind decoding), until receiving the PDCCH with its identifier.
The example UL subframe structure of Figure 11 diagram in a wireless communication system.
Referring to Figure 11, UL subframe can be divided into control area and data area in a frequency domain.It can be to control area
One or more physical uplink control channels (PUCCH) are distributed to carry uplink control information (UCI).It can be to number
One or more physical uplink shared channels (PUSCH) are distributed according to region to carry user data.If UE uses SC-
FDMA scheme emits for uplink, then cannot emit PUCCH and PUSCH, simultaneously to keep single carrier property.
The UCI carried by PUCCH can be different in size and purpose according to PUCCH format, and according to encoding rate
And it is different in size.For example, PUCCH format can be defined as follows.

In the UL sub-frame, the subcarrier far from direct current (DC) subcarrier is used as control area.In other words, it is located at UL to send out
The subcarrier for penetrating the both ends of bandwidth is assigned to UL control information transmitting.DC subcarrier is retained to be emitted without being used in signal

The PUCCH of UE is used for distribution to the RB in subframe.RB couples of RB occupies different sons in two time slots and carries
Wave.This is referred to as more than RB pairs of the frequency hopping that boundary of time slot is distributed to PUCCH.However, RB is to accounting for if not using frequency hopping
With identical subcarrier.Unrelated with frequency hopping, the PUCCH for a UE is assigned to one RB pairs in a subframe, and
Therefore, in a UL subframe, identical PUCCH is emitted in each time slot by a RB once, in total twice.
Hereinafter, the RB of each PUCCH transmitting for a subframe is to the referred to as region PUCCH or PUCCH resource.
In addition, for convenience of description, the PUCCH of carrying acknowledgement/non-acknowledgement (ACK/NACK) is referred to as ACK/NACK
PUCCH.Bearer Channel quality indicator (CQI)/precoding matrix indicators (PMI)/rank information (RI) PUCCH is referred to as
Channel state information (CSI) PUCCH, and the PUCCH for carrying scheduling request (SR) is referred to as SR PUCCH.
The PUCCH resource emitted from BS to UE assignment for UCI according to explicit or implicit scheme.
UCI, ACK/NACK, CQI, PMI, RI, SR etc. can be emitted by the control area of UL subframe.
In a wireless communication system, the mutual transmitting/receiving signal of BS and UE or data.If BS/UE emits to UE/BS
Data, then UE/BS decodes received data.If being successfully decoded data, emit ACK to BS/UE.If data decode
Failure then emits NACK to BS/UE.In 3GPP LTE system, UE receives data cell (for example, PDSCH) from BS, and
By being emitted by carrying implicit PUCCH resource determined by the PDCCH resource for the scheduling information of the data cell to BS
For the ACK/NACK of the data cell.
Figure 12 diagram determines the example of the PUCCH resource for ACK/NACK.
In LTE system, the PUCCH resource of ACK/NACK is not used for each UE distribution in advance, and is located at cell
In multiple UE each time point in a manner of dividing use multiple PUCCH resources.Specifically, based on carrying PDSCH
Scheduling information PDCCH come implicitly determine for UE ACK/NACK transmitting PUCCH resource, the PDSCH carrying pair
The DL data answered.Wherein emitting the whole region of PDCCH in DL subframe includes multiple control channel elements (CCE), also, to
The PDCCH of UE transmitting includes one or more CCE.Each CCE includes multiple resource element groups (REG) (for example, 9
REG).When excluding reference signal (RS), a REG is made of four continuous RE.UE is emitted by implicit PUCCH resource
ACK/NACK, the implicit PUCCH resource are used in composition by specific CCE in the index of the CCE of the received PDCCH of UE
What the function of index (for example, first or minimum CCE index) was exported or calculated.
Referring to Figure 12, each PUCCH resource index corresponds to the PUCCH resource for ACK/NACK.Such as institute in Figure 12
Show, it is assumed that PDSCH scheduling information is emitted to UE by the PDCCH that is made of the CCE of number 4 to 6, then UE is by from CCE
Number 4, the i.e. minimum CCE of PDCCH, export or the PUCCH calculated, for example, emitting ACK/ to BS by PUCCH number 4
NACK.Figure 12 shows an example, wherein exists in DL subframe up to M' CCE, and exists in the UL sub-frame until M
A PUCCH resource.Although M' can be equal to M, M' can be different from M, and can carry out mapping CCE in an overlapping manner
And PUCCH resource.
For example, it is as follows PUCCH resource can be indexed determination.
[equation 1]
Here, n(1) PUCCHIt is the PUCCH resource index for ACK/NACK transmitting, N(1) PUCCHIt is received from higher level
Signalling value, and nCCEIndicate the minimum CCE index for PDCCH transmitting.
Figure 13 is shown in the exemplary communication under single carrier case.Figure 13 can correspond to the communication in LTE system

The data area configured in DL subframe emits and receives data, and the control area by being configured in UL/DL subframe come
Transmitting and reception control information.For this purpose, UL/DL subframe carries signal on various physical channels.Although being based on FDD for convenience
Scheme provides the explanation of Figure 13, but explanation above can also be applied to by the time domain by the radio frame of Fig. 8
It is divided into the TDD scheme of UL frame and DL frame.
Figure 14 is shown in the exemplary communication under multi-carrier case.
Lte-a system is polymerize using carrier wave or aggregated bandwidth, and carrier wave polymerization or aggregated bandwidth are by polymerizeing multiple UL/DL frequencies
Rate block is to use broader UL/DL bandwidth using broader frequency band.Multicarrier system or carrier wave polymerization (CA) system refer to
It is to polymerize each there is system of the multiple carrier waves of the bandwidth more narrower than target bandwidth to support for broadband.When polymerization has
When multiple carrier waves of the bandwidth more narrower than target bandwidth, the bandwidth for polymerizeing carrier wave can be limited to the band used in conventional systems
Width, to keep the backward compatibility with legacy system.For example, LTE system can support the band of 1.4,3,5,10,15 and 20MHz
Width, and the bandwidth supported in LTE system can be used to support ratio from advanced LTE (LTE-A) system that LTE system improves
The broader bandwidth of 20MHz.Furthermore it is possible to new bandwidth is defined to support CA, and it is unrelated with the bandwidth used in conventional systems.
Term multicarrier can be used interchangeably with term CA and aggregated bandwidth.Continuous CA and discontinuous CA are collectively referred to as CA.In order to join
It examines, when only one component carrier (CC) is used for the communication in TDD, this corresponds in the single carrier case (non-CA) of Figure 13
Communication.UL CC and DL CC are also known respectively as UL resource and DL resource.
For example, with reference to Figure 14, it is 5 CC of 20MHz to support that each of which can be polymerize in each of UL and DL
The bandwidth of 100MHz.Corresponding CC can be continuous or discontinuous in a frequency domain.For convenience, Figure 14 shows wherein UL
The situation that the bandwidth of CC is identical as the bandwidth of DL CC and the two is symmetrical.However, it is possible to independently determine each CC's
Bandwidth.For example, can be with 5MHz (UL CC0)+20MHz (UL CC1)+20MHz (UL CC2)+20MHz (UL CC3)+5MHz
The mode of (UL CC4) configures the bandwidth of UL CC.Also asymmetric CA can be configured, wherein the quantity of UL CC is with DL CC's
Quantity is different.Asymmetric CA can due to available band limitation and be generated, or network configuration shape can be passed through intentionally
At.For example, even if Y (≤X) a DL can be restricted to by the received frequency band of particular UE when BS manages X DL CC
CC.In this case, UE needs to monitor DL signal/data by Y CC transmitting.In addition, even if when BS manages L UL CC
When, M (≤L) a UL CC can be limited to by the received frequency band of particular UE.Confined DL CC or UL for particular UE
CC is referred to as service UL or the DL CC configured in particular UE.BS can by activate by the BS CC managed some or all
Or by disabling by some CC that BS is managed come to the CC of UE distribution provisions quantity.BS can change activation/disabling CC, and
And change the quantity of activation/disabling CC.Meanwhile BS can with cell specifically or UE specifically configure UE should monitor first/
Received Z DL CC (wherein, 1≤Z≤Y≤X) is used as main DL CC.Moreover, BS can be with cell specifically or UE specifically matches
/ main UL the CC of received N number of UL CC (wherein, 1≤N≤M≤L) conduct should be monitored first by setting UE.In this way, it is used for
The main DL or UL CC of the limitation of particular UE is also referred to as service UL or the DL CC configured in particular UE.It can be specific with cell
, UE group specifically or UE is specifically configured to the various parameters of CA.
Once BS cell is specifically or UE specifically can use CC to UE distribution, then at least the one of distributed CC is not disabled
It is a, except non-reconfigurable is switched to the whole CC of UE distribution or UE.It is distributed hereinafter, removing non-reconfigurable to the whole CC of UE
Otherwise the CC not disabled is referred to as main CC (PCC), and BS is free to activation/disabling CC and is referred to as auxiliary CC
(SCC).Single carrier communication is used to communicate using a PCC for the communication between UE and BS, and without using SCC.Together
When, PCC and SCC can also be distinguished based on control information.For example, specific control information can be set to only by specific
CC transmitting/reception.Such specific CC can be referred to as PCC, and other one or more CC can be referred to as one or more
A SCC.For example, can correspond to such specific control information by the control information that PUCCH emits.Therefore, if
The control information emitted on PUCCH only can be emitted to BS from UE by PCC, then wherein there is the UL CC of the PUCCH of UE
UL PCC can be referred to as, and other one or more UL CC can be referred to as one or more UL SCC.As another
Example, if the particular UE can receive the DL synchronization signal as specific control information from BS using UE specific CC
(SS).In this case, the particular UE using come by receive DL SS establish the initial DL time synchronization DL CC (that is,
For attempting to access the DL CC of the network of BS) DL PCC can be referred to as, and other one or more DL CC can be claimed
For one or more DL SCC.In the communication system according to LTE-A version 10, multi-carrier communication uses each UE
One PCC and without using SCC or use one or more SCC.However, this is the definition according to LTE-A, and can be
Future allows each UE to use the communication of multiple PCC.PCC can be referred to as main CC, anchoring CC or main carrier, and SCC can
CC or subcarrier are assisted to be referred to as.
LTE-A manages radio resource using the concept of cell.Cell is defined as the combination of DL resource and UL resource,
That is, the combination of DL CC and UL CC.Here, UL resource is not indispensable component.However, this is in current LTE-A standard
In be defined, and in future, can permit and UL resource is used alone to configure cell.Therefore, it can be used alone DL resource
Or cell is configured using both DL resource and UL resource.When supporting CA, can be indicated by system information in DL resource
Association between the carrier frequency of the carrier frequency and UL resource (or UL CC) of (or DL CC).For example, can be believed by system
Block type 2 (SIB2) is ceased to indicate the combination of DL resource and UL resource.Here, in carrier frequency instruction each cell or CC
Frequency of heart.The cell run on basic frequency (or PCC) can be referred to as main plot (PCell), and quenching frequency (or
SCC the one or more cells run on) can be referred to as one or more supplementary cells (one or more SCell).Dominant frequency
Rate (or PCC) refers to executing the frequency (or CC) that initial connection is established or connects the process that re-establishes for UE.PCell can be with
Refer to the cell indicated during the switching process.Quenching frequency (or SCC) refers to match after executing RRC connection and establishing
The frequency (or CC) set, and can be used for providing other radio resource.PCell and SCell may be collectively termed as servicing small
Area.Therefore, it is not configured CA or UE not supporting CA, being in RRC_CONNECTED (RRC connection) state, there is only
A serving cell being only made of PCell.Meanwhile CA, UE in RRC_CONNECTED state are configured with to it,
There may be one or more serving cells, and all serving cells may include a PCell and one or more
SCell.However, can permit serving cell will include multiple PCell in future.For CA, in addition in starting initial safe activation
In connection establishment process after process except the PCell of initial configuration, network can also for support CA UE configure one or

In multi-carrier systems, BS can emit in given one or more cells (or one or more CC) to UE
Multiple data cells, and UE can emit the ack/nack signal for multiple data cells in a subframe.UE can be with
One or more cell (or DL CC) is assigned for receiving the PDSCH for being used for DL data receiver.RRC signaling can be passed through
To be semi-statically configured or reconfigure the cell (or one or more DL CC) for UE.Furthermore, it is possible to pass through L1/L2 (matchmaker
Body access control (MAC)) control signaling dynamically activates/disables the cell (or one or more DL CC) for UE.Cause
This, will be changed by the maximum quantity of the UE ACK/NACK bit emitted according to the cell (or DL CC) that can be used for UE.That is, wanting
It is configured/is reconfigured by RRC by the maximum quantity of the ACK/NACK bit of UE transmitting, or by L1/L2 signaling with sharp

Figure 15 describes the concept that a MAC layer in BS manages multiple carrier waves.Figure 16 describes a MAC layer in UE
Manage the concept of multiple carrier waves.
Referring to Figure 15 and Figure 16, a MAC layer management one or more frequency carrier is to execute transmitting and reception.Because
It is needed not be continuously by the frequency carrier of a MAC layer management, so more flexible resource management is possible.In Figure 15 and 16
In, for convenience, a physical layer (PHY) indicates a CC.Here, a PHY does not necessarily mean that independent radio frequency (RF) is filled
It sets.In general, an independent RF device indicates a PHY, but not limited to this.One RF device may include several PHY.
Figure 17 describes the concept that multiple MAC layers in BS manage multiple carrier waves, and Figure 18 describe it is multiple in UE
MAC layer manages the concept of multiple carrier waves.Figure 19 describes another concept that multiple MAC layers in BS manage multiple carrier waves, and
And Figure 20 describes another concept that multiple MAC layers in UE manage multiple carrier waves.
Other than structure as shown in figures 15 and 16, multiple MAC layers rather than a MAC layer can control multiple
CC, as shown in Figure 17 to 20.
As shown in FIG. 17 and 18, each MAC layer can be with one-to-one corresponding each carrier wave of control.Such as Figure 19 and
Shown in 20, each MAC layer can control each carrier wave, and a MAC about partial carrier wave with one-to-one correspondence
Layer can be about other carrier Control one or more carrier waves.
System suitable for explanation above is system of one carrier wave of support to the more a carrier waves of N, and carrier wave can be
Continuous or discontinuous carrier wave, and it is unrelated with UL/DL.TDD system is configured as managing N number of carrier wave, each carrier wave includes DL
Emit with UL, and FDD system is configured as in UL and DL using multiple carrier waves respectively.FDD system can support asymmetry
CA, wherein the quantity of the polymerization carrier wave in UL and DL and/or the bandwidth of carrier wave are different.
If the quantity for the CC polymerizeing in UL is equal to the quantity for the CC polymerizeing in DL, CC can be configured and to own
CC it is compatible with the CC used in conventional systems.However, not supporting the CC of compatibility from present invention exclusion.
For convenience of description, although corresponding to emitting on DL CC #0 when emitting PDCCH on DL CC#0
Explanation is provided under the hypothesis of the PDSCH of PDCCH, but it is clear that can using cross carrier wave dispatch so that with DL CC#0 not
Emit PDSCH on same DL CC.

Under PUCCH format 1a and 1b.Repeat identical control letter on a timeslot basis in the subframe of PUCCH format 1a and 1b
Breath.The different cyclic shifts (CS) (frequency domain code) of constant amplitude zero auto-correlation (CG-CAZACC) sequence that UE is generated by computer and
It is orthogonal to cover (OC) or the orthogonal different resource for covering coding decoder (OCCc) (time domain extended coding decoder) to emit
Ack/nack signal.OC includes such as Walsh/DFT orthogonal code.It, can be with if the quantity of CS is that the quantity of 6 and OC is 3
18 UE in total are multiplexed in same Physical Resource Block (PRB) based on individual antenna.Any time domain (FFT modulation after) or
Orthogonal sequence w0, w1, w2 and w3 are applied in any frequency domain (before FFT modulation).For SR transmitting PUCCH format 1 with
PUCCH format 1a and 1b is identical in time slot level structure, and different in modulation scheme.
It can be provided by radio resource control (RRC) signaling come the PUCCH being made of to UE distribution CS, OC and PRB
Source, to emit for SR and be fed back for the ACK/NACK for semi-persistent scheduling (SPS).As described with reference to Fig. 12, for
The ACK/ of dynamic ACK/NACK (or ACK/NACK for impermanent scheduling) feedback or the PDCCH for instruction SPS release
NACK feedback, can be used come with the minimum CCE index of the PDSCH or the corresponding PDCCH of PDCCH that are discharged for SPS it is hidden to UE

Figure 23 is shown in the scene for emitting UCI in the wireless communication system for supporting CA.For convenience of description, in this example
In it is assumed that UCI is ACK/NACK (A/N).However, UCI may include control information, such as CSI (for example, CQI, PMI and RI)
With scheduling request information (for example, SR), without limit.
Figure 23 illustrative exemplary asymmetry CA, wherein 5 DL CC are linked to single UL CC.It can be from the view of transmitting UCI
Point setting asymmetry CA.That is, the DL CC-UL CC association for UCI can be set to and the DL CC-UL for data
CC association is different.For convenience, if it is assumed that each DL CC can be carried up to two code words, and be used for each CC
ACK/NACK quantity depend on each CC set by code word maximum quantity (for example, if BS sets specific CC
It sets until two code words are set the ACK/NACK of the CC even if a code word is used only in specific PDCCH on the CC
It is 2, i.e. the maximum quantity of the code word on the CC), then at least two UL ACK/NACK bits are needed for each DL CC.
In this case, at least ten ACK/NACK bit is needed to emit on single UL CC for received on 5 DL CC
The ACK/NACK of data.If also indicating that discontinuous transmitting (DTX) state for each DL CC, at least 12 ratios are needed
Spy (=56=3125=11.61 bit) emit to be used for ACK/NACK.Because can get in conventional PUCCH format 1a and 1b
Until two ACK/NACK bits, so the structure cannot emit increased ACK/NACK information.Although CA is given increase
The example of the cause of the quantity of UCI, but the situation be also likely to be due to the quantitative increase in antenna and in TDD system and
The presence of backhaul subframe in relay system and occur.Similar to ACK/NACK emit, when on single UL CC transmitting with it is more
When the relevant control information of a DL CC, the amount for the control information to be emitted also increases.For example, relevant to multiple DL CC
The transmitting of CQI/PMI/RI information can increase UCI payload.
In Figure 23, UL anchoring CC (the also referred to as main CC of UL PCC or UL) is the CC for emitting PUCCH or UCI on it, and
And can by cell specifically/UE specifically determines.In addition, DTX state can explicitly be fed back, or can be made by feedback
It obtains and shares identical state with NACK.
Hereinafter, reference attached drawing to be proposed to the method for being used to effectively emit increased UCI.It is used for specifically, proposing
Emit new PUCCH format/signal processing operations/resource allocation methods of increased UCI.By proposed by the present invention new
PUCCH format is referred to as CA PUCCH format or the PUCCH relative to the PUCCH format 2 defined in traditional LTE version 8/9
Format 3.The technical characteristic of the PUCCH format proposed can be easily applied to can in the same manner or in a similar manner
Transmit any physical channel (for example, PUSCH) of UCI.For example, the embodiment of the present invention is suitable for emission control information periodically
Period PUSCH structure or aperiodic ground emission control information aperiodic PUSCH structure.
Following situations will be focused on and describe drawings and examples of the invention: using the PUCCH format 1/1a/ of tradition LTE
The UCI/RS symbolic construction of 1b (normal CP) is as the subframe applied to PUCCH format 3/timeslot-level UCI/RS symbolic construction.
However, for convenience, illustratively defining subframe/timeslot-level UCI/RS symbolic construction of PUCCH format 3, and the present invention
It is not limited to such specific structure.It can be designed according to system and freely change UCI/RS in PUCCH format 3 of the invention
The quantity of symbol and position.It is, for example, possible to use the R/S symbol structures of the PUCCH format 2/2a/2b of traditional LTE to define root
According to the PUCCH format 3 of one embodiment of the present of invention.
The PUCCH format 3 of embodiment according to the present invention can be used for emitting the UCI of any type or size.For example, can
To emit the information of such as HARQ ACK/NACK, CQI, PMI, RI and SR with the PUCCH format 3 of embodiment according to the present invention.
The information can have the payload of any size.For convenience of description, explanation below is focused on according to the present invention
The transmitting of the ACK/NACK information of PUCCH format 3.
Figure 24 to 27 illustrates the PUCCH format structure and its signal processing operations for feeding back multiple ACK/NACK bits.
For example, PUCCH format can be used when feeding back multiple ACK/NACK bits in multicarrier environment.Such PUCCH lattice
Formula can be referred to as PUCCH format 3, and the conventional inline of itself and PUCCH format 1 and 2 is distinguished.
Figure 24 to 27 illustrates the PUCCH format structure based on DFT.According to the PUCCH structure based on DFT, PUCCH is by DFT
Precoding, and time domain OC is applied to it at SC-FDMA grades before transmission.Hereinafter, the PUCCH format based on DFT is referred to as
PUCCH format 3.
Figure 24 diagram uses the exemplary structure of the PUCCH format 3 of the OC of spreading factor (SF) 4 (SF=4).Referring to figure
24, channel coding blocks to information bit a_0, a_1 ..., a_M-1 (for example, multiple ACK/NACK bits) channel coding, and
Generation coded-bit (or code word) b_0, b_1 ..., b_N-1.M is the size of information bit, and N is the big of coded-bit
It is small.The information bit includes UCI, such as multiple ACK/ of multiple data (or PDSCH) received on multiple DL CC
NACK.Here, combined coding information bit a_0, a_1 ..., a_M-1, and with the type/number of the UCI of configuration information bit/
Size is unrelated.For example, if information bit includes multiple ACK/NACK for multiple DL CC, for entire bit information
Channel coding is executed, rather than channel coding is executed for each DL CC or each individual ACK/NACK bit.Pass through
Channel coding generates single code word.Channel coding including but not limited to repeats, simplex coding, Randt's Miller (RM) are compiled
Code, perforation RM coding, tail biting convolutional encoding (TBCC), low-density checksum (LDPC) coding or turbo coding.Although not
Show, it is contemplated that order of modulation and stock number and can to coded-bit carry out rate-matched.The rate-matched function can
Partly to be covered in channel coding blocks, or realize in individual functional block.For example, channel coding blocks can pass through
(32,0) RM coding is executed about multiple control information and obtains single code word, and can execute circular buffering rate-matched.
Modulator by modulating-coding bit b_0, b_1 ..., b_M-1 come generate modulation symbol c_0, c_1 ..., c_
L-1.L is the size of modulation symbol.Modulation scheme is executed by changing the amplitude and phase of transmitting signal.Modulation scheme includes
Such as n phase-shift keying (PSK) (n-PSK) and n quadrature amplitude modulation (QAM) (wherein, the integer that n is two or more).Specifically, modulation methods
Case includes binary system PSK (BPSK), orthogonal PSK (QPSK), 8-PSK, QAM, 16-QAM or 64-QAM.
Divider by modulation symbol c_0, c_1 ..., c_L-1 be divided into time slot.By modulation symbol be divided into the rank of time slot/
Mode/scheme is not limited to specific one.For example, divider can will sequentially be adjusted since the first modulation symbol (localized approach)
Symbol processed is divided into time slot.In this case, modulation symbol c_0, c_1 ..., c_L-1 can be assigned to time slot 0, and adjust
Symbol c_L/2, c_L/2+1 processed ..., c_L-1 can be assigned to time slot 1.It, can be with when modulation symbol is divided into time slot
Interweave (arrangement) modulation symbol.For example, the modulation symbol of even-numbered can be distributed to time slot 0, and can be distributed to time slot 1
The modulation symbol of odd-numbered.Modulation treatment and division processing can sequentially exchanged.
DFT precoder executes DFT precoding (for example, 12 point DFT) about the modulation symbol for being divided into time slot, so as to
Generate multicarrier waveform.Referring to fig. 24, modulation symbol c_0, c_1 for being distributed to time slot 0 ..., c_L/2-1 by DFT precoding be
DFT symbol d_0, d_1 ..., d_L/2-1, and to time slot 1 distribute modulation symbol c_L/2, c_L/2+1 ..., c_L-1
By DFT precoding be DFT symbol d_L/2, d_L/2+1 ..., d_L-1.DFT precoding can be replaced with another linear
It operates (for example, Walsh precoding).
Signal (in the time domain) of the extension blocks in the extension DFT precoding of SC-FDMA symbol level.Come using extended code (sequence)
The time domain executed in SC-FDMA symbol level extends.Extended code includes quasiorthogonal code and orthogonal code.Quasiorthogonal code includes still unlimited
In pseudo noise (PN) code.Orthogonal code includes but is not limited to walsh code and DFT code.Although orthogonal code is retouched for convenience of description
The typical case for extended code is stated, but orthogonal code can be replaced with into quasiorthogonal code.Extended code size or the maximum value of SF by
Quantity for controlling the SC-FDMA symbol of the transmitting of information limits.For example, if four SC-FDMA symbols are used for one
Control information transmitting in a time slot can then use orthogonal code w0, w1, w2 and w3 of length 4 in each time slot.SF
Indicate the degree of expansion of control information, and can be related to the antenna multiplexed order of multiplexing order or UE.SF can be depended on
System requirements and change into 1,2,3,4 ....Predefined SF or BS it can be believed by DCI or RRC between BS and UE
It enables and to indicate SF to UE.For example, if in SC-FDMA symbol of the perforation for controlling information one to emit SRS, have and subtract
The extended code of small SF (for example, SF=3 rather than SF=4) can be applied to the control information in corresponding time slot.
When being mapped to the subcarrier in PRB from the signal of operation generation above, and being converted by IFFT
Domain signal.CP is added to time-domain signal, and emits generated SC-FDMA symbol by the end RF.
Each operation will be more fully described under the hypothesis for 5 DL CC transmitting ACK/NACK.If each
DL CC can emit two PDSCH, then can be 12 bits, including DTX state for the ACK/NACK bit of the PDSCH.
Under the hypothesis that the time of QPSK and SF=4 extends, the size (after rate-matched) of encoding block can be 48 bits.Coding
Bit is modulated to 24 QPSK symbols, and QPSK symbol is divided into two time slots, each time slot includes 12 QPSK
Symbol.12 QPSK symbols in each time slot are converted into 12 DFT symbols by 12 point DFT.In each time slot
In 12 QPSK symbols be extended to four SC-FDMA symbols, and then quilt using the extended code of SF=4 in the time domain
Mapping.Because emitting 12 bits on [2 bit x, 12 subcarrier x, 8 SC-FDMA symbol], encoding rate is 0.0625
(=12/192).If SF=4, most four UE can be multiplexed with each PRB.
Figure 25 diagram uses the exemplary structure of the PUCCH format 3 of the OC of SF=5.
Other than the quantity and position of UCI SC-FDMA symbol and RS SC-FDMA symbol, with it is described in reference diagram 25
Identical mode executes basic signal processing operations.Can at the front end of DFT precoder preparatory application extension block.
In Figure 25, RS be can be used and those identical structures used in LTE system.For example, shifting can be recycled
Position basic sequence.The multiplexing capacity of data portion due to SF=5 but 5.However, passing through CS interval deltashift PUCCHTo determine RS
Partial multiplexing capacity.For example, multiplexing capacity can be 12/ Δshift PUCCH.In this case, for wherein Δshift PUCCH=

Whole multiplexing capacity can be limited to the smaller 4 of the two values.
Figure 26 diagram can be in the exemplary structure of the timeslot-level upper PUCCH format 3 for increasing multiplexing capacity.
It can increase whole multiplexing by being extended to RS using the SC-FDMA symbol level with reference to described in Figure 24 and 25 and hold

In the case where not applying timeslot-level frequency hopping, again will by applying Walsh cover as unit of time slot
Multiplexing capacity doubles.As set forth above, it is possible to which [x1 x2]=[1 1], [1-1] or its transformation are used as OC.
As reference, the processing operation of PUCCH format 3 is not limited to the sequence shown in Figure 24 to 27.
Channel selection
Channel selection refers to expression/hair of the specific information carried out by the selection specific resources from multiple resources
It penetrates.Common channel selection is the scheme for emitting specific information by the combination of resource and constellation.
Here, physical time-frequency resource and/or sequence resources (for example, CS value) Lai Zhiding resource can be passed through.Example
Such as, it in LTE version 8PUCCH format 1/1a/1b, can be selected by the combination of OC, CS and physical resource unit (PRU)
Specific resources.It can be assumed that distinguishing the multiple resources for executing channel selection on it by the combination of three kinds of resources above.
It is, for example, possible to use the channel selecting methods shown in following table 3.
[table 3]
In table 3 above and in the following description, be expressed as a, b, c ... value can indicate by channel Ch-
X (x=1,2,3 ...) in modulation (for example, BPSK, QPSK etc.) caused by constellation value.Alternatively, be expressed as a, b, c ...
Value can be the value of assigned sequence or the multiplexing of assigned code, scrambling or covering, rather than constellation value.Accordingly, with respect to
Ch-x be expressed as a, b, c ... value can be the value that can be distinguished therebetween, and do not limit for area between these values
The method divided.Particularly, in the following description, for convenience of description, about Ch-x be expressed as a, b, c ... value claimed
For modulation value.
In addition, be expressed as a, b, c ... value can be scheduled particular value, rather than 0.For example, a can be '+1 ',
And b can be ' -1 '.
In the example of table 3, even if transmitting same value, which channel can also be depended on for emitting and emitting different
Information (that is, ACK or NACK).For example, ACK is emitted, the transmitted value a in the part RS of resource 1 (that is, channel 1), and
Transmitted value b in the data portion of resource 1.NACK is emitted, emits a in the part RS of resource 2 (that is, channel 2), and
Emit b in the data portion of resource 2.In this way, emit signal for being determined by which resource and emit not
The method of same information can be referred to as channel selection.
In table 3, the simple examples without using complicated constellation mapping are shown, but other constellation can be used and reflect
It penetrates to be used to emit more information.Table 4 is shown using the two kinds of example for distinguishing constellation mapping (for example, BPSK).
[table 4]
In table 4 above, a, b and c can be the particular value other than 0.Pay attention to, it is preferred that b and c are in constellation
On away from each other.For example, a is used as '+1 ', also, b and c can be, respectively, used as '+1 ' and ' -1 ' or be, respectively, used as
' -1 ' and '+1 '.In the example of table 4, for ACK/ACK transmitting, transmitting is modulated to the value of b in resource 1 (channel 1), and
And transmitting is modulated to the value of c in resource 1 (channel 1) for ACK/NACK transmitting.In addition, being provided for NACK/ACK transmitting
Transmitting is modulated to the value of b in source 2 (channel 2), and transmitting is modulated in resource 2 (channel 2) for NACK/NACK transmitting
For the value of c.
Defined in table 5,6 and 7 shown in below used in traditional LTE version 8/9, in TDD for ACK/
The mapping relations of the channel selection of NACK transmitting.In LTE version 8/9, TDD ACK/NACK multiplexing can have and TDD
The identical meaning of ACK/NACK channel selection, but they support system (for example, LTE-A or LTE editions in following multicarriers
This 10) in have different meanings.
In following table 5,6 and 7, in a tdd system, K:{ k can be indexed by DL relevant episode0,k1,…kM-1(such as
Defined in the table 12 described later) determine value M.For example, if M=2 in table 5, two PUCCH resourcesWithAnd the QPSK constellation ' b (0) in each PUCCH resource, b (1) ' can be used for emitting two kinds
The ACK/NACK information of type, including space binding (that is, the ACK/NACK for multiple code words is bundled).
Specifically, UE uses PUCCH format 1b in ACK/NACK resource in subframe nUpper transmitting bit ' b
(0),b(1)'.It can be by generating value ' b (0), b (1) ' and ACK/NACK according to the channel selection of following table 5,6 and 7
ResourceThe multiplexing transmitting of the ACK/NACK as M=2, M=3 and M=4 is shown respectively in table 5,6 and 7.If ' b (0), b
(1) ' it is mapped to NACK/ACK, then UE emits ACK/NACK response not in subframe n.
[table 5]
[table 6]
[table 7]
In table 5,6 and 7, HARQ-ACK (i) instruction is used for the HARQ ACK/NACK/ of i-th (0≤i≤3) data cell
DTX result.DTX expression be not launched be used for the data cell of corresponding HARQ-ACK (i) or UE detect not yet with
The corresponding data cell of HARQ-ACK (i).In this specification, HARQ-ACK is interchangeably used with ACK/NACK.It can be right
Most four PUCCH resources are occupied (that is, n in each data cell(1) PUCCH,0To n(1) PUCCH,3).Pass through the PUCCH from occupancy
The PUCCH resource selected in resource emits the ack/nack signal of multiplexing.In table 5,6 and 7, n(1) PUCCH,xInstruction is used
In the PUCCH resource of practical ACK/NACK transmitting, and ' b (0) b (1) ' indicates emit by selected PUCCH resource two
A bit is used QPSK to modulate.For example, if UE has been successfully decoded four data cells, UE as in table 7
By being connected to n(1) PUCCH,1PUCCH resource come to BS emit (1,1).Because of the combination of PUCCH resource and QPSK symbol
All obtainable ACK/NACK cannot be indicated, so NACK and DTX are coupled and (are expressed other than in some cases
For NACK/DTX).
Meanwhile in applicable LTE-A (or the LTE version 10) system of the present invention, about for applying channel selecting method
Channel selection mapping relations be not particularly limited.For example, can define as shown in table 8 to 10 for emitting ACK/
The channel selection mapping relations of nack message.Table 8 is defined for 2 bit ACKs/NACK mapping relations, and table 9, which defines, to be used for
3 bit ACKs/NACK mapping relations, and table 10 is defined for 4 bit ACKs/NACK mapping relations.
[table 8]
[table 9]
[table 10]
Alternatively, can define as shown in table 11 for 1 bit to 4 bit ACKs/NACK channel mapping relations.?
In the example of table 11, b0 can be generated and can be generated for the transmitting of 1 bit ACK/nack message, b0 and b1 and
For 2 bit ACKs/NACK information transmitting, b0, b1 and b2 can be generated and for 3 bit ACKs/NACK information hairs
It penetrates, and b0, b1, b2 and b3 can be generated and for 4 bit ACKs/nack message transmitting.
[table 11]
For the UL ACK/NACK of DL transmitting in multicarrier support system
In multicarrier system or CA support system, DL resource can be defined as DL CC, and UL resource can be determined
Justice is UL CC.In addition, the combination of DL resource and UL resource can be referred to as cell.If asymmetrically configuring DL CC and UL
CC, then cell can only refer to DL CC (or UL CC).For example, existing if configuring specific UE with serving cell
An one DL CC and UL CC.However, existing if configuring specific UE with two or more serving cells in number
In amount the DL CC equal with cell and quantitatively be equal to or less than DL CC UL CC.It is configured when with multiple serving cells
When particular UE, the multicarrier environment of quantity of the quantity of wherein UL CC greater than DL CC can be supported.
It can be indicated by the system information in DL transmitted on resources in the carrier frequency of DL and UL resource (in cell
Frequency of heart) between association.For example, the combination of DL resource and UL resource can be configured by the association defined by SIB2.
According to definition above, CA can refer to the set of two or more cells with different carrier frequencies.That is,
Wherein to have the case where two or more serving cells of different carrier frequencies configure specific UE that can be referred to as CA ring
Border.For supporting the UE of CA, one or more SCell that can polymerize with PCell to support the bandwidth increased.
In this case, serving cell can be PCell or SCell.For not supporting CA's to be in RRC_CONNECTED
UE in state, there is only a serving cells including PCell.Meanwhile for be configured with CA in RRC_CONNECTED
UE in state, serving cell refer to include one or more cells of PCell and SCell set.
PCell is the center cell of the control related communication in the serving cell configured in CA environment.PCell is by UE
The cell for indicating or using in initial connection establishment process, connection reestablishment procedure or handoff procedure.UE can be only in its PCell
Upper reception and transmitting PUCCH.In addition, UE can execute monitoring process, obtains and change for the system information only on PCell
Become.UE, BS is supported to can be used including mobilityControlInfo's CA
RRCConnectionReconfiguration message is only changed by handoff procedure.
Next, SCell refers to the cell in the serving cell configured in CA environment other than PCell.?
PUCCH is not present on SCell.If adding SCell, BS can be by dedicated signaling to the UE offer for supporting CA and in RRC_
The relevant all system informations of operation on the SCell of CONNECTED state.It, can be by via one for SCell
The release and addition of the SCell of RRCConnectionReconfiguration message executes the change in system information.
BS can emit the dedicated signaling with the parameter different from the parameter for including in the broadcast message on SCell to UE.First
After beginning safe activation process, BS can be for UE in addition to PCell is (as the small of serving cell configuration during connecting establishment process
Area) except also configure one or more SCell.PCell may be used to provide safety input and higher hierarchy system information, and
SCell may be used to provide other DL resource, and provide UL resource as necessary.BS can be used including or not include
The RRCConnectionReconfiguration message of mobilityControlInfo passes through RRC connection reconfiguration procedure
Independently to add, eliminate or correct SCell.
In CA environment, PhyCellId, SCellIndex and ServCellIndex can be defined as the related ginseng of RRC
Number/information element (IE).PhyCellId can have the integer of range from 0 to 503, and be used as the physics of cell
Layer identifier.SCellIndex can have the integer of range from 1 to 7, and be used as the identifier of SCell.
ServCellIndex can have the integer of range from 0 to 7, and be used as serving cell (PCell or SCell)
Identifier.ServCellIndex with value 0 can be applied to PCell, and for SCell, can apply
SCellIndex.That is, the cell with minimum (or minimum) cell index in ServCellIndex can be defined as
PCell。
In short, multiple carrier waves in CA can be divided into PCell and SCell as UE special parameter.Specifically
UE can have the serving cell of one or more configurations.If there is the serving cell of multiple configurations, then one of serving cell
It is PCell, and other cells are SCell.If UE has the serving cell of multiple configurations in TDD, which UL indicated
The UL-DL configuration that subframe is used to emit the ACK/NACK of the PDSCH for emitting in specific DL subframe can be in all cells
In it is identical.
In addition, UE can be measured to BS transmitting from one or more CC in a predetermined C C, such as CSI (including
CQI, RI, PMI etc.) UCI and HARQ ACK/NACK.For example, feeding back if necessary to multiple ACK/NACK, then UE can be collected
From PCell DL CC and one or more SCell DL CC received ACK/NACK feedback (for example, ACK/NACK be multiplexed or
ACK/NACK binding), and it is anti-to the collected ACK/NACK of BS transmitting in the UL CC of PCell that a PUCCH can be used
Feedback.
In the present invention, when emitting multiple ack/nack signals for multiple DL transmitting by a PUCCH,
The unit (one or more subframes and/or one or more carrier waves) for constituting multiple DL transmittings is referred to as bundled window.That is, time domain
Binding refers to being bundled in the ack/nack signal for DL transmitting in multiple subframes.The binding of the domain CC refers to being bundled in multiple
The ack/nack signal for DL transmitting in CC.Time domain/the domain CC binding refers to being bundled in multiple subframes and multiple CC
Ack/nack signal for DL transmitting.It is of the invention although ACK/NACK binding can be executed by logic and operation
It is without being limited thereto, and can be used such as logic or other operations.
In addition, the list for actually executing time domain binding using logical AND (or logic or) operation and/or the domain CC bundlees
Member can be referred to as practical bundled window.I.e., it is possible to there are one or more practical bundled windows in a bundled window.It changes
Sentence is talked about, and the size of bundled window is equal to or more than the size of practical bundled window.Here, can be using for for a DL

In the following description, there is the PDSCH of corresponding PDCCH, for the PDSCH of DL SPS release and no pair
The PDSCH of the PDCCH answered is collectively referred to as the DL for needing ACK/NACK to emit transmitting.
This hair described in detail below when the ACK/NACK above for DL transmitting is applied to multicarrier system
Bright example.
For convenience of description, example of the invention will be described under following hypothesis.However, the embodiment of the present invention is not
It is limited to following hypothesis.
(1) there may be a PCell and one or more SCell.
(2) there can be the PDSCH with corresponding PDCCH on PCell and one or more SCell.
(3) can only there be the PDCCH of instruction DL SPS release on PCell.
It (4) can only there are the PDSCH of no corresponding PDCCH (=SPS PDSCH) on PCell.
(5) cross scheduling from PCell to one or more SCell can be supported.
(6) cross scheduling from one or more SCell to PCell is not supported.
(7) cross scheduling from one or more SCell to another SCell (or other SCell) can be supported.
In explanation of the invention, time domain binding and/or the binding of the domain CC indicate logic and operation.However, it is possible to pass through all
The other methods of such as logic or operation bundle to execute time domain binding and/or the domain CC.That is, time domain binding or the binding of the domain CC refer to
Be for using single PUCCH format ACK/NACK response in, by multiple ACK/NACK in multiple subframes or CC
The method for being expressed as that there is the ACK/NACK information of less bit.In other words, time domain binding or the binding of the domain CC refer to being used for
It is any means of N-bit (M >=N) by the ACK/NACK information representation of M-bit.
It, can be by using PUCCH format 1a/1b, PUCCH format in the system that multicarrier and/or TDD are applied to
3 channel selection emits multiple ACK/NACK bits using the channel selection of PUCCH format 3.For being used for PUCCH format
PUCCH resource index, implicit mapping, explicit mapping or the combination implicitly and explicitly mapped can be used.Implicit mapping can be with
Use the method for obtaining PUCCH resource index based on the minimum CCE index of corresponding PDCCH.Explicit mapping can make
Scheduled concentration is being configured by RRC with indicating or obtaining by the ACK/NACK resource indicator (ARI) in PDCCH
The method of PUCCH resource index.
Related to the present inventionly, when the format for emitting multiple ACK/NACK bits with reference to Figure 24 to 27 (for example, retouch
The PUCCH format 3 stated) when, explicit resource distribution is substantially based on to execute the resource allocation of PUCCH format 3.
Specifically, the UE for being configured as PUCCH format 3 can be assigned by explicitly (for example, passing through RRC signaling) and is used for
The orthogonal resource of the format.Furthermore it is possible to being configured by RRC in scheduled orthogonal resource by for emitting on SCell
PDSCH PDCCH in ARI value determine final PUCCH resource.In this case, ARI is used as based on aobvious
The offset of the PUCCH resource value transmitted with signal likes, or can serve to indicate that and to use in one or more PUCCH resources
Which of collection.
In order in PDCCH include ARI information, it may be considered that reuse the field of existing PDCCH to be used for ARI mesh
Method.PDCCH may include transmission power control (TPC) field.The original purpose of TPC field be control PUCCH and/
Or the transmission power of PUSCH, and can be made of 2 bits.
As described above, when only emitting ARI on SCell, it can be by the TPC field weight in the PDCCH on SCell
Newly it is used as ARI.Meanwhile the TPC field in the PDCCH on PCell can be used for the transmission power control of PUCCH.
In 10 system of LTE version, because the PDCCH of the PDSCH for dispatching PCell cannot be received on SCell
(that is, the cross carrier wave scheduling for not allowing to carry out the PDSCH of PCell from the PDCCH of SCell), so UE only connects on PCell
The meaning for receiving PDSCH can be equal to the meaning that UE only receives PDCCH on PCell.
The explicit ACK/NACK resource allocation configured by RRC signaling can be executed as follows.
Firstly, the PDCCH corresponding with PDSCH (that is, PDCCH for dispatching PDSCH) on SCell may include
Resource for configuring from one or more RRC obtains the information (for example, ARI) of specific PUCCH resource.
Next, if not receiving PDCCH corresponding with PDSCH on SCell and being received on PCell
PDSCH can then apply following one of situation.It is possible, firstly, to using the PUCCH resource defined in LTE version 8 (that is,
PUCCH format 1a/1b).Second, the PDCCH corresponding with PDSCH on PCell may include for from one or more RRC
The resource of configuration obtains the information (for example, ARI) of specific PUCCH resource.
UE can be assumed all PDCCH having the same ARIs corresponding with PDSCH on SCell.
In this way, when ARI information to be defined as only emitting on SCell, if UE is in multicarrier and/or TDD
It is only received in system and (or only receives one or more on PCell for one or more PDSCH of PCell
PDCCH), then because UE not can know that the ARI information emitted from SCell, then not can determine that for will be by PUCCH lattice that UE is used
The final resource index of formula (PUCCH format 3).
Even if be designed to solve problem above the invention proposes for when UE only receive for PCell one
The final money for being used for PUCCH format is determined when a or multiple PDSCH (or only receiving one or more PDCCH on PCell)
The method of source index.
In various examples of the invention, for convenience of description, wherein UE only receives one or more for PCell
The case where a PDSCH (or in which UE only the case where receiving one or more PDCCH on PCell), is called ' only PCell for short
It receives '.Here, the reception definition only PCell reception about UE.If the present invention is applied to multicarrier environment, UE can
With the cell of the cell or multiple configurations that are configured with one.If UE has the cell of a configuration, which be can be
PCell, and if UE has the cell of multiple configurations, which can be by a PCell and one or more SCell structure
At.The present invention can be applied to one of both of these case or both two kinds of situations.That is, only PCell reception condition can be answered
Use CA environment and non-CA environment.
Moreover, as set forth above, it is possible to by new PUCCH format, that is, PUCCH format 3 is used for for leading in a tdd system
The ACK/NACK transmitting of the received DL transmitting of multiple DL subframes is crossed, even if when UE includes the cell of a configuration.When UE includes
When the cell of multiple configurations, PUCCH format 3 can also be used in FDD or TDD system.I.e., it is possible in CA system or non-CA
PUCCH format 3 is used in TDD system.
Moreover, the candidate resource collection for PUCCH format 3 can be configured by RRC in various examples of the invention.It can
By the way that the value of ARI information (can be expressed as reusing for the TPC field of PDCCH) is determining or value from the ARI information
Obtain the specific PUCCH resource in PUCCH resource Candidate Set.In brief, RRC configuration resource candidate in from
The ARI for including in PDCCH is obtained will be by 3 resource of PUCCH format that UE is used.When passing through the PDCCH on SCell as described above
When reusing to express ARI of TPC field (2 bit size), ARI has the size of X bit, and X can be defined
It is 2.A resource of four PUCCH resource candidates is expressed it is, for example, possible to use 2 bit A RI.
In order to the convenience using associated explanation of PUCCH format 3, by needing the single of orthogonal resource
Antenna, which executes, describes the present invention under the hypothesis emitted.It may be evident, however, that the invention is not limited thereto, and even if work as to PUCCH format
When the 3 application such as multi-antenna emission diversity scheme of orthogonal space resource transmitting diversity (SORTD), the principle of the present invention is also with phase
Same mode is applicable in.
Now, the exemplary hypothesis of the invention for 3 resource allocation of PUCCH format is described based on explanation above.
Resource for PUCCH format 3 can be expressed asAnd it is used for four orthogonal moneys of PUCCH format 3
Source candidate can be expressed asWithAny UE can pass through RRC signaling quilt
Assign such four orthogonal resources.RRC signaling for example can be four individual RRC signals.It can be believed by a RRC
Enable a set being made of to UE notice four orthogonal resourcesBy
The UE for assigning four PUCCH resource candidates can be determined come final at four based on the value by addition received ARI instruction
A PUCCH resource in PUCCH resource candidate
Following table 13 shows the example resource allocation for PUCCH format 3 in single-antenna transmission.
[table 13]
Hereinafter, based on explanation above come the various embodiments of detailed description of the present invention.
Embodiment 1
The present embodiment 1 is related in only PCell reception condition (that is, only receiving one or more PDSCH's for PCell
Situation or only on PCell receive one or more PDCCH the case where) under using predefined resource allocation method.
In the received situation of only PCell, the resource index of PUCCH format 3 can determine.That is, being received in non-only PCell
In the case where, UE can show that PUCCH resource is indexed from ARI received on SCell, and in only PCell reception, UE can be with
Use scheduled PUCCH resource index.
Specifically, new index can be made a reservation for, so that UE, which can determine, to be used in the received situation of only PCell
3 resource of PUCCH format.New index can have meaning identical with the ARI on SCell.In other words, the index
It can serve to indicate that any one of the resource Candidate Set configured by RRC signaling.It can be with predefined rule (or particular value)
Form limit index, which is used to indicate the resource of the particular sorted in resource Candidate Set
(for example, first resource or the last one resource).
For example, can determine that the index of 3 resource of PUCCH format can be defined as system under only PCell reception condition
Particular value.Alternatively, the index can be configured to eNB particular value or UE particular value by RRC.
Figure 28 is to be shown in the predefined resource allocation determined in the received situation of only PCell for PUCCH resource
Flow chart.
In step S2810, UE can configure (for example, RRC signaling) by higher level to receive including for PUCCH
The PUCCH resource Candidate Set of four resources of format 3
In step S2820, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only
PCell reception condition.If the determination in step S2820 is the result is that no (that is, non-only PCell reception condition), executes step
Rapid S2830, and S2840 is thened follow the steps (that is, only PCell reception condition) if YES.
In step S2830, the weight by the TPC field in one or more PDCCH of SCell is can be used in UE
Newly using indicated ARI come from four PUCCH resource candidate calculating/selection PUCCH resources to be used by
(that is, a resource index).
Meanwhile because not receiving PDCCH on SCell in step S2840, UE can be according to predefined rule
Then (or predefined index) selects a PUCCH resource from four PUCCH resource candidates.In the diagram example of Figure 28,
Predefined rule is that the last one PUCCH resource is selected to index in PUCCH resource Candidate Set.That is, in step S2940,
UE can be calculated/be selected
After step S2830 or step S2840, UE can be used resource corresponding with the index for calculating/selecting and pass through
PUCCH format 3 emits ACK/NACK information.
Embodiment 2
The present embodiment 2 is related to a kind of for making a reservation for other resource index and being used for using the other resource index
(that is, the case where only receiving the one or more PDSCH for being used for PCell or only being connect on PCell the case where only PCell is received
Receive one or more PDCCH the case where) under PUCCH resource distribute method.
In the received situation of only PCell, it is capable of the other resource index of predetermined PUCCH format 3.That is, UE can be
Show that PUCCH resource indexes from ARI received on SCell in the non-received situation of only PCell, and UE can be in only PCell
It is indexed in received situation using scheduled other PUCCH resource.Predetermined index in example 1 above be for pair
In the predetermined index of one of the PUCCH resource candidate of UE configuration, and embodiment 2 it is different from embodiment 1: make a reservation for and for
The other resource index of the PUCCH resource candidate separation of UE configuration.
According to this embodiment, for example, if the resource candidate configured using four RRC of 2 bit A RI and definition
Set, then can by RRC signaling to UE with signal transmit an other resource candidate.Then, the resource of RRC configuration
Candidate Set includes 5 PUCCH resource indexes, and one of predetermined resource index (for example, the last one index) can be with
It is defined as only using under only PCell reception condition.Alternatively, can discretely define use with four PUCCH resource candidates
In the received resource candidate of only PCell.In both above situation the two, it can be distributed to UE and be only used for only PCell
The reservation resource index (that is, resource index not specified by the ARI on SCell) of reception condition.Although here, preferred
It is that will not be used for the resource candidate of the received other resource candidate of only PCell with four existing RRC configurations
Overlapping, but can permit overlapping in some cases.
Figure 29 is to be shown in the other predefined resource allocation determined under only PCell reception condition for PUCCH resource
Flow chart.
In step S2910, UE can configure (for example, RRC signaling) by higher level to receive including for PUCCH
The PUCCH resource Candidate Set of four resources of format 3
In step S2920, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only
PCell reception condition.If the determination in step S2920 is the result is that no (that is, non-only PCell reception condition), executes step
Rapid S2830, and S2940 is thened follow the steps (that is, only PCell reception condition) if YES.
In step S2930, from 5 PUCCH resource candidates, regular scheduled four PUCCH resources are waited according to the rules
The person of choosing is (for example, four low index PUCCH resources With) in, UE can be used logical
The TPC field crossed in one or more PDCCH of SCell reuses indicated ARI from four PUCCH resource candidates
PersonCalculating/selection PUCCH resource to be used by.
Meanwhile because not receiving PDCCH on SCell in step S2940, UE can be according to predefined rule
Then select a PUCCH resource.The predefined rule can be the PUCCH resource candidate choosing for configuring from 5 RRC
Select the last one resourceRule.Can limit will not be used to determine in step S2930 in 5 PUCCH resources
Four rules in candidate and one rule in step S2940 for determination in 5 PUCCH resource candidates
Then it is overlapped.However, in some cases it may the resource candidate that restrictive rule is overlapped selection.
After step S2930 or step S2940, UE can be used resource corresponding with the index for calculating/selecting and pass through
PUCCH format 3 emits ACK/NACK information.
Embodiment 3
Embodiment 3 be related to using downlink allocation index (DAI) come in only PCell reception condition (that is, only receiving
The case where one or more PDSCH for PCell or only the case where receiving one or more PDCCH on PCell) under
The method of PUCCH resource distribution.
In above-described embodiment 1 and 2, it has been described that for obtaining in only PCell reception for PUCCH format 3
Method of the resource index without the use of other physical layer signaling (for example, PDCCH signaling).Embodiment 3 be related to it is a kind of definition and
Using the method for the information of the function of being able to carry out ARI in physical layer signal received on PCell, although as in existing side
ARI cannot be received in case on SCell like that, since PDCCH being not present on SCell.Specifically, the embodiment is related to
Method of the DAI information for including in PDCCH as ARI information is used under only PCell reception condition.
The DAI field in PDCCH is defined in a tdd system, and distributes (or PDSCH scheduling) about DL to assign
DAI.When UE emits the ack/nack signal for multiple DL assignment (PDSCH) in a UL subframe, can be obtained from DAI
The information of quantity about DL assignment (PDSCH) will emit ack/nack signal for DL assignment (PDSCH).For example, working as UE
When to BS transmitting multiple DL are assigned with ack/nack signal (being bundled using ACK/NACK) of (PDSCH), wherein UE fails
The situation for receiving a part of (that is, loss) multiple PDCCH is likely to occur.At this point, being transmited to it because UE not can know that
The case where PDSCH corresponding with the PDCCH of reception failure, it is possible that there is mistake in ACK/NACK generation.It can make
Such problems is solved with DAI.In existing TDD system, for example, a UL subframe corresponds to N number of DL wherein
In the case where frame, if sequentially assigning (that is, sequentially counting) DAI to the PDCCH emitted in N number of DL subframe, UE can lead to
The DAI information crossed in PDCCH, which is known whether, has been correctly received previous PDCCH.
In this embodiment, it is contemplated that DAI when using PUCCH format 3 in the PDCCH of PCell is not used in original
The case where beginning purpose, proposes and is re-used as DAI to be used to determine the ARI of PUCCH resource assignment.Specifically, even if in TDD
PUCCH format 3 is used in system, DAI information is not needed yet in the operation as the full multiplexer mode of ACK/NACK, in ACK/
Time domain binding or the domain CC (or frequency domain) binding are not executed in the full multiplexer mode of NACK.Therefore, DAI field can be re-used as
For the received ARI of only PCell.
Figure 30 is to be shown under only PCell reception condition DAI field being used for showing for the ARI that PUCCH resource determines
The flow chart of example.
In step S3010, it includes for PUCCH lattice that UE, which can configure (for example, RRC signaling) by higher level and receive,
The PUCCH resource Candidate Set of four resources of formula 3
In step S3020, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only
PCell reception condition.If the determination in step S3020 is the result is that no (that is, non-only PCell reception condition), executes step
Rapid S3030, and S3040 is thened follow the steps (that is, only PCell reception condition) if YES.
In step S3030, the TPC field in one or more PDCCH by SCell is can be used again in UE
Using indicated ARI from four PUCCH resource candidate calculating/selection PUCCH resources to be used by it (that is, one
A resource index).
Meanwhile in step S3040 because not receiving PDCCH on SCell, UE can be used by
DAI field in the PDCCH of PCell reuse indicated ARI carry out from four PUCCH resource candidates selection will be by
Its PUCCH resource used (that is, a resource index).
After step S3030 or step S3040, UE can be used resource corresponding with the index for calculating/selecting and pass through
PUCCH format emits ACK/NACK information.
Embodiment 3-1
Embodiment 3-1 is related in only PCell reception condition (that is, only receiving the one or more PDSCH for being used for PCell
In the case where or only the case where receiving one or more PDCCH on PCell) under in binding subframe using identical ARI value
Example.
The terms bundled subframe (or bundled window) used in explanation of the invention is indicated when by a UL PUCCH
Emit a unit being made of when responding for the ACK/NACK of the DL subframe in bundled window DL subframe, rather than actually
The unit of binding is executed in time domain or the domain CC (or frequency domain).
For example, such as (showing DL relevant episode index K:{ k in table 12 above in LTE version 8TDD system0,k1,…
kM-1) shown in, it gives about the one or more DL subframes (subframe n-k) which is used previous and emits for specific
UL subframe (the definition of the ACK/NACK response of the DL transmitting in subframe n).In the example description binding subframe by table 12,
When emitting the ACK/NACK response for the DL transmitting in one or more specific DL subframes in specific UL subframe, this
A or multiple specific DL subframes, which are referred to as, bundlees subframe.For example, the binding subframe for UL subframe 2 is in UL-DL configuration 4
DL subframe 12,8,7 and 11, and the binding subframe for UL subframe 3 is DL subframe 6,5,4 and 7.
If in TDD use PUCCH format 3, can be emitted as described above by a UL PUCCH for
The ACK/NACK response of DL transmitting in multiple DL subframes.Here, when according to embodiment 3 under only PCell reception condition more
When detecting one or more PDCCH in a DL subframe, if different by ARI (or DAI) value that corresponding PDCCH is indicated,
Do not know which ARI value for calculate/select PUCCH resource.
The problem in order to prevent should be maintained at the ARI value of the PDCCH emitted on PCell in binding subframe in the same manner
(that is, value of DAI field).
Embodiment 3-2
Embodiment 3-2 is related to applying the example of identical ARI value in the CC of binding.
The terms bundled subframe (or bundled window) used in explanation of the invention is indicated when by a UL PUCCH
Emit the ACK/NACK response for DL CC in bundled window and with binding in the presence/absence of it is unrelated when by DL CC structure
At a unit, rather than unit of binding is actually executed in time domain or the domain CC (or frequency domain).For example, when applying
When ACK/NACK is multiplexed entirely, the CC of binding can have meaning identical with the quantity of CC configured for UE.
If using PUCCH format 3 in TDD or FDD system, can occur in which as described above through a UL
PUCCH emits the case where responding for the ACK/NACK of multiple DL CC.Here, ' emitting the ACK/NACK for multiple DL CC
Response ' meaning can indicate that there are DL transmittings in PCell and one or more SCell.At this point, if PCell's
ARI value in PDCCH is different from the ARI value in the PDCCH of SCell, then does not know and calculated/selected using which ARI value
PUCCH resource.
Therefore, in order to prevent above problem, should be maintained in the same manner on PCell be used for ARI purpose field (DAI
Field) value and on SCell for ARI purpose field (TPC field) value.
Embodiment 3-3
Embodiment 3-3 is related to applying the example of identical ARI value in binding CC and subframe.
When (for example, when multiple CC and multiple subframes are a binding units) considering both embodiment 3-1 and 3-2,
If the ARI value in corresponding cell or corresponding subframe is different, calculating/selection of PUCCH resource may be unclear.Cause
This, other than the ARI value being maintained in PDCCH on PCell and SCell is equal, the PDCCH that is maintained in multiple subframes
In ARI value it is equal.
Embodiment 4
Embodiment 4 be related to it is a kind of using TPC field come in only PCell reception condition (that is, only receiving for PCell
One or more PDSCH the case where or only on PCell receive one or more PDCCH the case where) under PUCCH resource divide
The method matched.Embodiment 4 can be applied to the two kinds of situations wherein applied or ACK/NACK is not applied to be multiplexed entirely.Embodiment 4
Wherein application or not two kinds of feelings of application space binding (ACK/NACK for multiple code words is bundled) can also be applied to
Condition.
In example 3 above, it has been described that for even determining PUCCH resource (example in only PCell reception
Such as, the resource of PUCCH format 3) resource index without the use of other physical layer signaling method.Embodiment 3 is related to working as DAI
It is not used as being used for when original applications (for the purposes for the index that DL distribution (or PDSCH is dispatched) sequentially assigns) using DAI
The example of ARI purpose.Therefore, when in a tdd system use PUCCH format 3 when, if support time domain binding or the domain CC (or frequency
Domain) binding, then DAI information is needed for original purpose, to generate correct ACK/NACK information.
Therefore, in example 4, DAI is not used in other purposes under only PCell reception condition.The present embodiment 4 proposes
A kind of side that TPC field in one or more PDCCH on PCell is re-used as to ARI under only PCell reception condition
Method.
(that is, there are PDCCH transmittings on SCell) under non-only PCell reception condition, as described above, on SCell
TPC field is reused for ARI.However, under only PCell reception condition, because there is no the hair of TPC field on SCell
It penetrates, so the new method for emitting correct ACK/NACK must be defined.
According to embodiment 4, under only PCell reception condition, according to the one or more that pre-defined rule is determining on PCell
TPC field in specific PDCCH can be used for original transmission power control purpose, and one or more other PDCCH
TPC field can be used for ARI purpose.UE can be used only in the one or more determined according to pre-defined rule on PCell
The TPC field of specific PDCCH is come for original power control purpose, and other one or more are received on PCell
When PDCCH, the TPC field of one or more corresponding PDCCH can be construed to ARI by UE.
If TPC field is not used in original purpose, UE can the loss of energy include TPC field for power control
PDCCH, or if BS does not dispatch PDCCH, may slightly reduce the dynamic controlling determined for the UL transmission power of UE
Energy.However, the TPC value in PDCCH is not absolute value but for the opposite deviant of previous transmission power.Moreover, i.e.
It updates UE TPC value once or twice, preset transmission power can also be kept.In addition to using the TPC word in PDCCH
Section transmission power control method except, also provide supplement Poewr control method (this deviate the scope of the present invention, and because
This, will not be described in detail).Therefore, the loss of TPC value does not have considerable influence for network performance.
In the application present invention, it can be used according to the TPC field of one or more PDCCHs of the pre-defined rule on PCell
In original purpose (power control purpose).Hereinafter, the example that pre-defined rule will be described.
As the first example, the TPC field definition of the PDCCH emitted in the n-th subframe of binding subframe can be used
In original purpose.Here, n can be the value for being used to indicate one or more subframes of part in binding subframe.For example, if
N, then can be determined as being used to indicate the value of the 0th subframe or the last one subframe by one of instruction binding subframe.Furthermore, it is possible to root
N is differently determined according to the quantity (or size of binding subframe) of binding subframe.With similar side shown in the table 12
Formula, the quantity for bundling subframe for example can be 1,2,3,4 or 9.Alternatively, difference can be bundled according to the binding scheme newly defined
The subframe of quantity.Moreover, n can indicate the set of multiple subframes in binding subframe.For example, being bundled when n is 0 and 1
The TPC field of the PDCCH emitted in the 0th and the 1st subframe in subframe can be used for original purpose.Therefore, if n is with multiple
Value, the then quantity that the PDCCH of the test described below that retracts is used for being received increase the quantity of n value.For example, if n has
There are two value, then being received come the quantity of the PDCCH for the test that retracts should be 2.Exemplary theory below the present invention
In bright, for convenience of description, n has a value.
As the second example, the TPC field in binding subframe in the PDCCH with n-th of DAI value can be defined
For for original purpose.Here, n can be 0,1,2,3 ... one of.Alternatively, if DAI value is construed to 1,2,3,
4 ..., then n can be determined as to 1,2,3,4 ... a value of.In this case, even if in the full multiplexer mode of ACK/NACK
It, can also be in one or more PDCCH on PCell in (the case where not applying wherein time domain or the domain CC (or frequency domain) to bundle)
Including DAI field.Furthermore, it is possible to determine n in the form of the set of multiple values.For example, this can be indicated when n is 0 and 1
TPC field in the PDCCH with the 0th and the first DAI value is used for original purpose.Alternatively, when DAI value is construed to open from 1
When the beginning, if n is 1 and 2, the TPC field in the PDCCH with the first and second DAI values can be indicated as original
Beginning purpose.Therefore, when n has multiple values, the quantity of the PDCCH for the rollback test for being received to be used to describe later increases
The quantity of n value.For example, if it should be 2 that n tool, which there are two value, is received come the quantity of the PDCCH for the test that retracts,.?
In explanation below the present invention, for convenience of description, there is n a value to be used as example.
In the second example above, what DAI value can indicate to distribute with dibit size to UE is used for one or more
Continuous (sequence) counter of PDCCH.The value of the actual transmission of DAI field can be can be construed to 1,2,3 and of DAI value by UE
4 one of 0,1,2 and 3 (or 00,01,10 and 11 when being expressed as 2 bit value).By the DAI value about actual transmission
It is described below with the DAI value explained by UE.
The value of the actual transmission of DAI field can be 0,1,2 or 3, and UE the value can be construed to first, second,
Third or the 4th PDCCH.In this case, about the DAI value of actual transmission, the n=0 in particular UE is (0,1,2 and 3
In set) the first PDCCH of instruction.
The value of the actual transmission of DAI field can be 0,1,2 or 3, and UE the value can be construed to first, second,
Third or the 4th PDCCH.In this case, about the DAI value explained by UE, the n=1 in particular UE is (1,2,3 and 4
In set) the first PDCCH of instruction.
In short, the practical DAI value 00,01,10 and 11 for including in PDCCH can be respectively mapped to be explained by UE
DAI value 1,2,3,4.
As described in the above example, in the one or more PDCCH or the DAI=n that is determined by the value of n of the n-th subframe
One or more PDCCH in TPC field be used for original purpose (power control), and in other one or more PDCCH
In TPC field can be re-used as ARI.
Figure 31 is to be shown under only PCell reception condition TPC field being used for showing for the ARI that PUCCH resource determines
The flow chart of example.In the example of Figure 31, it is assumed that the TPC field of the specific PDCCH determined according to predefined rule is used for
Original purpose, and the TPC field of other one or more PDCCH is re-used as ARI.
In step S3110, it includes for PUCCH lattice that UE, which can configure (for example, RRC signaling) by higher level and receive,
The PUCCH resource Candidate Set of four resources of formula 3
In step S3120, when PUCCH format 3 emits for ACK/NACK, UE can determine whether situation is only
PCell reception condition.If the determination in step S3120 is the result is that no (that is, non-only PCell reception condition), executes step
Rapid S3130, and S3140 is thened follow the steps (that is, only PCell reception condition) if YES.
In step S3130, the TPC field in one or more PDCCH by SCell is can be used again in UE
Using indicated ARI come from four PUCCH resource candidate calculating/selection PUCCH resources to be used by it (that is,
One resource index).
Meanwhile in step S3140, UE can determine the quantity of received PDCCH whether be 1.Because when in SCell
On execute step S3140 when not receiving PDCCH, so the quantity of the received PDCCH of institute indicate it is received on PCell
The quantity of PDCCH.If the definitive result in step S3140 is to be (that is, the quantity of received PDCCH is on PCell
1) S3150, is thened follow the steps, and if the definitive result in step S3140 is no (that is, received on PCell
1) quantity of PDCCH is greater than, then follow the steps S3160.
In step S3150, if UE only receives a PDCCH on PCell, the TPC of PDCCH is can be used in UE
Field is used for original purpose (power control), and because UE, which can be determined, not to be received without any other PDCCH
ARI value.In this case, UE is limited to run under traditional 8 mode of LTE version.This can be referred to as in fall-back mode
Operation.Fall-back mode is identical as the ACK/NACK of the PUCCH format 1a/1b using usual definition transmitting operation, and therefore,
By description is omitted.In step S3140 about the quantity of received PDCCH whether be that 1 determination can be claimed
It is tested to retract, where it is determined whether using fall-back mode.
Meanwhile because executing step S3160 when the quantity of PDCCH received on PCell is greater than 1, UE can be with
Purpose is used for original using the TPC field in one of PDCCH, and can be by the TPC of other one or more PDCCH
Field is construed to for ARI.Then, UE, which can be used, reuses meaning by the TPC field in the PDCCH of PCell
The ARI shown come from four PUCCH resource candidate calculating/selection PUCCH resources to be used by it (that is, a resource
Index).
After step S3130 or step S3160, UE can be used resource corresponding with the index for calculating/selecting and pass through
PUCCH format 3 emits ACK/NACK information.
In the diagram example of Figure 31, explanation is given under following hypothesis: UE, which is only checked, receives (or detection)
PDCCH quantity, and when the quantity of received PDCCH be 1 when, the TPC field of corresponding PDCCH is used for original mesh
's.
However, if the quantity of received PDCCH be that the TPC field of 1, PDCCH can be used for original purpose or can
To be reused for ARI purpose.Therefore, when the quantity of received PDCCH be 1 when, always do not execute fall-back mode operation, and
And preferably, detailed determination is executed.
Figure 32 is to be shown in the received situation of only PCell TPC field being used for the ARI that PUCCH resource determines
Another exemplary flow chart.In the example of Figure 31, it is assumed that according to the TPC for the specific PDCCH that predefined rule determines
Field is used for original purpose, and the TPC field of other one or more PDCCH is re-used as ARI.
In the diagram example of Figure 32, operation (step S3210, S3220, S3230 identical with the operation of Figure 31 are omitted
And S3240) explanation.
It is held when the definitive result of step S3240, which is, is (that is, when the quantity of PDCCH received on PCell is 1)
Row step S3250.In step S3250, whether the PDCCH for determining that this is received is predefined PDCCH (that is, PDCCH
TPC field whether be used for original purpose).For example, it may be determined that received PDCCH whether be binding subframe first son
PDCCH in frame.As another example, can determine whether the received PDCCH of institute is with DAI value 1 (hereinafter, DAI=
1) PDCCH.If it is determined that result be it is yes, then follow the steps S3260, and if not, then follow the steps S3270.
In step S3260, because the TPC field in a received PDCCH should be used for original purpose, UE
ARI can be regarded as it is unknown, and can be run in fall-back mode (using PUCCH format 1a/1b ACK/NACK emit).
Step S3270 can be executed when the result of step S3240 is no.That is, if received PDCCH quantity it is big
In 1, then as it is assumed that there is only one wherein TPC field be used for original purpose PDCCH, so UE can identify at least one
The TPC field of PDCCH is re-used as ARI.The ARI value that the TPC field for carrying out self-corresponding PDCCH can be used in UE is come four
Calculating/selection PUCCH resource to be used by it (that is, a resource index) in a PUCCH resource candidate.
When the definitive result of step S3250 is no, step S3270 can also be executed.That is, if the received PDCCH of institute
Quantity be 1, then because corresponding PDCCH is not the PDCCH that wherein TPC field is used for original purpose, UE can be identified
The TPC field of a corresponding PDCCH is reused for ARI out.The TPC field for carrying out self-corresponding PDCCH can be used in UE
ARI value come calculate/select to be used by it the PUCCH resource in four PUCCH resource candidates (that is, one money
Source index).
In step S3270, resource corresponding with the index for calculating/selecting, which can be used, in UE comes through PUCCH format 3
Emit ACK/NACK information.
Embodiment 4-1
Embodiment 4 is related to the case where only PCell is received (that is, only receiving the one or more for PCell
The case where PDSCH or only the case where receiving one or more PDCCH on PCell) under in binding subframe using identical
The example of ARI value.
The terms bundled subframe (or bundled window) used in explanation of the invention is indicated when by a UL PUCCH
Emit a list being made of when responding for the ACK/NACK of the DL transmitting in the DL subframe in bundled window DL subframe
Member, rather than the unit of binding is actually executed in time domain or the domain CC (or frequency domain).
For example, such as (showing DL relevant episode index K:{ k in table 12 above in LTE version 8TDD system0,k1,…
kM-1) shown in, the one or more DL subframes (subframe n-k) previous about which are given for emitting in specific UL
Subframe (the definition of the ACK/NACK response of the DL wireless communication system in subframe n).It describes to bundle in the example by table 12
In subframe, as the ACK/NACK that transmitting emits the DL in specific one or multiple DL subframes in specific UL subframe
When response, this specific one or multiple DL subframes be referred to as and bundle subframe.For example, being used for UL subframe in UL-DL configuration 4
2 binding subframe is DL subframe 12,8,7 and 11, also, the binding subframe for UL subframe 3 is DL subframe 6,5,4 and 7.
If in TDD use PUCCH format 3, can be emitted as described above by a UP PUCCH for
The ACK/NACK response of DL transmitting in multiple DL subframes.Here, according to the above embodiments 4, the case where only PCell is received
Under multiple PDCCH are detected in multiple DL subframes.If as having indicated by the PDCCH for the TPC field for being re-used as ARI
ARI (or TPC) value it is different, then it is ambiguous to be, which ARI value for calculate/select PUCCH resource.
Here, in addition to having the PDCCH for being confirmed as according to predefined rule the TPC field for original purpose for example,
PDCCH with DAI=1) except, there is the PDCCH for the TPC field for being re-used as ARI can correspond to PDCCH (example
Such as, there is the PDCCH of the DAI value (hereinafter referred to as DAI > 1) greater than 1).
Therefore, the problem in order to prevent should equally be maintained at emitting on PCell in binding subframe, have quilt
The PDCCH of the TPC field of ARI is re-used as (that is, other than there is the PDCCH for the TPC field of original purpose
PDCCH ARI value (that is, value of TPC field)).
Embodiment 4-2
Embodiment 4-2 is related to applying the example of identical ARI value on the CC of binding.
The CC (or bundled window) of the terms bundled used in explanation of the invention indicate with binding in the presence/absence of
It is unrelated, when emitting the ACK/NACK response for the DL CC in bundled window by a UL PUCCH, by DL CC
The unit constituted, rather than the unit of binding is actually executed in time domain or the domain CC (or frequency domain).For example, when applying
When ACK/NACK is multiplexed entirely, the CC of binding can have meaning identical with the quantity of CC configured for UE.
If using PUCCH format 3 in TDD or FDD system, can be sent out as described above by a UL PUCCH
Penetrate the ACK/NACK response for multiple DL CC.Here, transmitting can be with for the meaning of the ACK/NACK response of multiple DL CC
Corresponding to wherein the case where there are DL transmittings on PCell and one or more SCell.At this point, if being used as having
ARI value in the PDCCH of the TPC field of ARI on PCell is different from the ARI value in the PDCCH on SCell, then obscures
It is unclear, which ARI value for calculate/select PUCCH resource.
Therefore, such problems in order to prevent, should equally keep the field (TPC for the ARI being used as on PCell
Field) value and the field (TPC field) of ARI being used as on SCell value.
Here, can equally be maintained on PCell, in addition to being determined according to predefined rule using TPC field
Come the PDCCH that is used for except original purpose PDCCH (for example, PDCCH with DAI=1) (for example, with DAI > 1
PDCCH ARI value) and the ARI value on SCell.
Embodiment 4-3
Embodiment 4-3 is related to applying the example of identical ARI value in the CC of binding and subframe.
That is, when considering the above embodiments 4-1 and 4-2 simultaneously (for example, when multiple CC and multiple subframes become a bundle
When tying up unit), if the ARI value in corresponding cell or corresponding subframe is different, calculating/select PUCCH resource may
It is ambiguous.Therefore, the ARI that should be equally maintained in the PUCCH on PCell and SCell, and at the same time, it should
The ARI being equally maintained in the PDCCH in multiple subframes.
Here, can equally keep on PCell in addition to being determined to according to predefined rule using TPC word
The PDCCH that section is come except the PDCCH (for example, PDCCH with DAI=1) for original purpose is (for example, have DAI > 1
PDCCH ARI value).
Figure 33 is the reality that diagram is used for original purpose or ARI purpose according to the DAI value on PCell using TPC field
Apply the figure of example.
DAI field value is used as the stored counts device of the PDCCH of each cell.That is, DAI value is in the every of cell
Sequentially increased 1 in one PUCCH.Always there are PDCCH in all subframes.
In the diagram example of Figure 33, on PCell, there is the PDCCH for DL distribution in first and third subframe.
DAI value is 0 in the PDCCH of the first subframe, and is 1 in the PDCCH of third subframe.On SCell, distributed for DL
PDCCH in sequentially provide DAI value.In Figure 33, diagram DAI value 0,1,2,3,0,1,2,3 ..., but in terms of the viewpoint of UE,
These values have with DAI value 1,2,3,4,1,2,3,4 ... identical meaning.
Relatively with above-described embodiment 4, according to the DAI value on PCell, the TPC field in PDCCH can be used for
Original purpose or ARI purpose.For example, in the PDCCH that the DAI value wherein on PCell is 0 (or being 1 in terms of the viewpoint from UE)
TPC field, that is, the TPC field in PDCCH in the first subframe of the PCell in Figure 33 is for original purpose (that is, function
Rate control), and the TPC field in another PDCCH on PCell is reused for ARI purpose.
With the above embodiments 4-1 into 4-3 relatively, can equally be maintained at binding subframe and/or binding cell
In ARI value.For example, if applying bundled window, UE in four subframes and five cells in the diagram example of Figure 33
It can be assumed that the value of the TPC field (that is, the TPC field for being used for ARI purpose) of the PDCCH on PCell and SCell is identical, remove
TPC field in the first subframe of PCell is (except wherein, 0) DAI is.
Embodiment 5
Embodiment 5 is related in only PCell reception condition (that is, only receiving the feelings of one or more PDSCH for PCell
Condition or only the case where receiving one or more PDCCH on PCell) under distributed using TPC field for PUCCH resource
Method.Embodiment 5 is applied to part ACK/NACK binding.Part binding refers to only in the time domain or at the domain CC (or frequency domain)
In binding.
DAI field is essentially available for original purpose (that is, in each cell as in example 4 above
On PDCCH stored counts device), and the TPC field in PDCCH can be re-used as ARI.In this case, in advance
The TPC field of fixed specific PDCCH is used for original purpose.Specific PDCCH can be determined as in binding subframe n-th
The PDCCH (describing this part in the embodiment 4 having been described above, and therefore, the repetitive description thereof will be omitted) of subframe.Or
Person can determine wherein PDCCH of the TPC field for original purpose based on DAI value.
The example of the upper surface of Figure 31 or 32 can be used as basic operation be applied to embodiment 5 with being substantially the same, and save
The repeated explanation provided in the embodiment 4 slightly having been described above.
Hereinafter, description is used for original mesh using TPC field based on DAI value when application obscure portions ACK/NACK is bundled
Or ARI purpose method detailed.
Firstly, the TPC field in the PDCCH with the n-th DAI value in the binding subframe of PCell can be defined
For for original purpose.The value of DAI field can be given 0,1,2,3 ... or can be given in terms of the viewpoint of UE
1、2、3、4、...。
In this case, (time domain binding or the domain CC (or frequency domain) bundle are applied in the part ACK/NACK tie-in mode
Tie up) in, it can include DAI field in one or more PDCCH on PCell.Here, should be determined based on pre-defined rule
The value for the DAI field for including in one or more PDCCH of PCell, and the present invention explained below is to the detailed of its
It is recommended that.
When the part application ACK/NACK bundlees, if the TPC field in the PDCCH of DAI=n is used for original purpose
(power control) can then determine that the DAI field of one or more PDCCH is as follows in various ways.
In traditional (LTE version 8) tdd mode, DAI indicates the accumulated value to the UE PDCCH distributed, and if letter
DAI can then be used as on whole cells (or CC) to multicarrier environment application DAI to the tired of the UE PDCCH distributed by single ground
Product value.For example, as shown in Figure 34, when bundling in four sub-frames and on two CC using ACK/NACK, can determine
DAI value is increased up the DAI value side that CC index increases in bundled window.However, it is difficult to which the program is applied to part
Binding.Therefore, it configures wherein in the LTE version 10TDD mode of multiple CC (or cell), it is desirable to provide another kind is for determining
The method of DAI value.
Figure 35 is to be shown in the exemplary figure that DAI value is determined in CA TDD system.
As an example, DAI value can indicate in multiple subframes of each cell to the cumulative number of the UE PDCCH distributed
It measures (Figure 35 (a)).For example, such method for determining DAI value is preferably used when binding when applying in the time domain.It can be with
The cumulative amount of PDCCH is applied in a manner of counting in the PDCCH in all subframes in a radio frame.Alternatively, can
To count the PDCCH's in practical bundled window (for actually executing the unit of ACK/NACK binding) in the time domain
Mode applies the cumulative amount of PDCCH.In the example of Figure 35 (a), by the unit of four subframes on SCell#2
The DAI in the PDCCH in three subframes in practical bundled window is determined as 0,1 and 2, and this is made using DAI field
For the example of stored counts device, it is the first PDCCH, the 2nd PDCCH which, which is used to indicate corresponding PUCCH respectively,
With the 3rd PDCCH.
As another example, DAI value can indicate to distribute in multiple CC (or cell) to UE in each subframe
PDCCH sum (Figure 35 (b)).For example, it is true that such DAI value is preferably used when application obscure portions bundle in the domain CC
Determine method.The sum of PDCCH can be determined as to the quantity of the PDCCH in all CC configured for UE.Alternatively, can be with
The sum of PDCCH is determined as in the practical bundled window in the domain CC (for the practical unit for executing ACK/NACK binding)
The quantity of PDCCH.In the example of Figure 35 (b), the DAI value in the PDCCH in the first subframe is 2, and this be using
DAI field is the example of 3 indicator as the sum for the PDCCH being used to indicate in corresponding subframe.
Alternatively, distributed in the multiple CC (or cell) that DAI value can be determined as in each subframe to UE
The stored counts device of PDCCH.Can according to the ascending order of the CC index (or cell index) in all CC configured for UE or
According to the ascending order of the CC index (or cell index) in the practical bundled window in the domain CC, each PDCCH is counted
The cumulative amount of PDCCH.For example, the DAI value in third subframe is determined as on PCell in the example of Figure 35 (b)
DAI=0, the DAI=1 on SCell#2, the DAI=2 on SCell#3 and the DAI=3 on SCell#4.
As shown in Figure 35 (a), if DAI is used as the tired of the PDCCH distributed in practical bundled window in the time domain
Product counter (that is, if DAI value being resetted on each CC), can equally apply use in addition to having on PCell
The TPC field of external PCell and the PDCCH on multiple SCell of PDCCH of specific DAI value (for example, DAI=0) use
In the embodiment of the present invention of ARI purpose.
Meanwhile as shown in Figure 35 (b), if DAI is used as dividing in the practical bundled window in the domain CC (or frequency domain)
The sum (or stored counts device) of the PDCCH matched is then likely difficult to using in addition to having the specific DAI value on PCell
The TPC field of the external PCell and the PDCCH on multiple SCell of the PDCCH of (for example, DAI=0) are come for ARI purpose
The embodiment of the present invention.
For example, it may be assumed that distributing PDCCH to specific UE in the first subframe and the second subframe, and do not exist
PDCCH is distributed on SCell.Although the situation is received corresponding to only PCell, by the DAI value of the received PDCCH of UE at this
Identical (for example, DAI=0) is (if DAI field is used as the finger of the sum of the PDCCH in corresponding subframe in two subframes
Show symbol or stored counts device, then according to above it is assumed that 0) DAI value is.Then, ambiguous for UE to be, it determines
The TPC field of which PDCCH in two PDCCH on PCell is used for ARI purpose, and the TPC field of which PDCCH is used
In original purpose.In other words, if determining DAI value by the reset schemes of the DAI value of each subframe, cannot apply makes
With on the external PCell and multiple SCell in addition to having the PDCCH of the specific DAI value (for example, DAI=0) on PCell
The TPC field of PDCCH carrys out the embodiment of the present invention for ARI purpose.
In order to solve the problems, such as above, method can be determined using different DAI values on PCell and SCell.For example,
On SCell, DAI is used as the stored counts of the PDCCH distributed in the practical bundled window in frequency domain (or the domain CC)
Device, and on PCell, DAI is used as the finger of the sum of the PDCCH distributed in practical bundled window in the time domain
Show symbol (or stored counts device).
Alternatively, needing for the DAI at least on PCell to be defined as PDCCH's in the time domain to apply the present embodiment
Stored counts device.Therefore, the DAI of one or more PDCCH on PCell is used as practical binding in the time domain
The stored counts device of the PDCCH distributed in window, and can be in the mode identical or different with the DAI that is used on PCell
To use the DAI of one or more PDCCH on SCell.
In it will be described below example of the invention, it is assumed that the DAI field of PDCCH is used as follows.
Firstly, the DAI field in PDCCH is used as dividing in multiple subframes in the binding of each CC is checked
The stored counts device of the PDCCH matched.That is, independently determining DAI value on each CC.Here, the bit value 0 of DAI field,
1,2 and 3 stored counts 1,2,3 and 4 is indicated respectively.That is, being expressed as 0,1,2 and 3 bit value in terms of the viewpoint of DAI field
1,2,3 and 4 can also be expressed as in terms of the viewpoint for the DAI value explained by UE.
Next, the DAI field of PDCCH is also used as on multiple CC in the bundled window in each subframe
The indicator of the sum of the PDCCH of distribution.The bit value 0,1,2 and 3 of DAI field can indicate respectively sum 1,2,3 and 4.That is,
0,1,2 and 3 bit value is expressed as in terms of the viewpoint of DAI field can also be expressed as 1,2,3 and in terms of the viewpoint by UE
4。
The diagram of Figure 36 to 39 uses the various examples of the DAI field in the binding of the domain CC.In the example of Figure 36 to 39, figure
Show that the 4DL-1UL configuration for 5 CC of UE configuration and in TDD (emits the DL in four DL subframes that is, collecting
ACK/NACK response with the PUCCH by a UL subframe come emit response).In addition, in the diagram example of Figure 36 to 39
In, bundled window includes 5 CC and four subframes.However, illustrated in Figure 36 to 39 wherein practical bundled window most significantly
Small the case where being 4,5 or 2.
Wherein not on PCell, using the example of the domain CC binding, (the practical bundled window in the domain CC is most for Figure 36 diagram
4) big size is.In this case, the DAI field of PCell is used as the accumulation of the PDCCH distributed to the subframe on PCell
Counter.The DAI field of SCell is used as the indicator of the sum to the SCell PDCCH distributed, in addition at each
Except PCell in subframe.
Figure 37 diagram is wherein not on PCell using the example (largest amount of the practical bundled window in the domain CC of the domain CC binding
It is 4).In this case, the DAI field of PCell is used as the stored counts of the PDCCH distributed to the subframe on PCell
Device.The DAI field of SCell is used as in each subframe to the finger of the sum of the PCell and SCell PDCCH distributed
Show symbol.Therefore, according to the DAI of SCell, UE be able to know that in corresponding subframe by BS distribution PDCCH sum (that is,
The sum of PDCCH on both PCell and SCell).UE can be used the DAI of PCell and about the PDCCH's distributed
The information of sum fails the PDCCH for detecting/receiving in practical bundled window to determine whether there is UE.Therefore, can
Efficiently perform the domain the CC ACK/NACK binding in corresponding subframe.
For example, in the diagram example of Figure 37, if in the PDCCH detected on SCell by UE in the second subframe
DAI value be 2, then UE can identify that the sum of the PDCCH distributed on PCell and multiple SCell is 3.Here, can be false
Determine UE and does not receive PDCCH in SCell#2.In this case, it cannot only not connect by the DAI value on SCell to determine
The PDCCH received whether be PDCCH in practical bundled window (that is, on SCell) or in addition to practical bundled window it
PDCCH in outer window (that is, on PCell).Because the DAI value on PCell is given accumulation meter in the time domain
Number, so UE, which can be confirmed in first and third subframe on PCell, is sequentially provided DAI value, and therefore confirmation is not present
UE fails the PDCCH detected on PCell.As a result, UE is able to know that PDCCH detects one of the SCell in the second subframe
The case where middle failure.
Example (the practical bundled window in the domain CC that Figure 38 diagram wherein independently applies the domain CC to bundle with PCell or SCell
Largest amount be 5).In this case, the DAI field of PCell is used as the PDCCH's distributed to the subframe on PCell
Stored counts device.The DAI field of SCell can serve to indicate that and distribute on both PCell and SCell in each subframe
PDCCH sum.Therefore, UE can be known by the DAI of SCell in subframe by BS distribution PDCCH sum (
The sum of PDCCH in both PCell and SCell).Because of the quantity of PDCCH of the DAI value instruction in practical bundled window,
So UE may determine whether that UE fails the PDCCH for detecting/receiving in practical bundled window.Therefore, Neng Gouyou
Effect ground executes the domain the CC ACK/NACK binding in corresponding subframe.
Figure 39 illustrates the case where largest amount of the wherein practical bundled window in the domain CC is 2.At this point, not applied on PCell
The domain CC binding, and it is possible to which configuration has two practical bundled windows of largest amount 2 on four SCell.The DAI of PCell
Field is used as the stored counts device of the PDCCH distributed to the subframe on PCell.The DAI field of SCell is used as removing
It is except the PCell in each subframe, distribute on SCell (most two SCell) in practical bundled window
The indicator of the sum of PDCCH.
To the application ACK/NACK part binding of embodiment 5 (binding in a time domain or in a frequency domain), and even if in the situation
Under, when ARI (=TPC field) value difference in bundled window, ACK/NACK bundling operation may be unclear.
Therefore, under only PCell reception condition, the TPC wherein in binding subframe on PCell can equally be kept
Field is reused for the ARI value of the PDCCH (that is, other than the wherein PDCCH of TPC for original purpose) of ARI purpose.Separately
Outside, it on the CC of binding, can be equally maintained at the value for the field (=TPC field) for being used for ARI purpose on SCell
Value on PCell for the field (=TPC field) of ARI purpose.Moreover, can equally be kept on binding CC and subframe
In addition to being confirmed as using TPC field come the PDCCH for original applications according to predefined rule (for example, having on PCell
The PDCCH of DAI=1) except the PDCCH PDCCH of DAI > 1 (for example, with) ARI value.Related to thisly, above
Embodiment 4-1 to 4-3 described in the principle of the present invention can be applied to the present embodiment 5 in an identical manner.In order to clear
Chu omits the explanation of repeating part.
UL ACK/NACK transmitting for the DL SRS transmitting in multicarrier support system
8 system of LTE version supports SPS.If having activated DL SPS transmitting, use can be allocated in advance by PDCCH
In the time/frequency resource of SPS transmitting, and the PDSCH of no corresponding PDCCH can be emitted by the resource of distribution.
ACK/NACK feedback relevant to SPS can be divided into two types.One seed type is the transmitting pair in subframe n
In ' ACK/NACK of the PDCCH ' for the DL SPS release that instruction is detected in one or more n-k by UE is fed back.It is another
Type is emitted in subframe n for ' emitting in one or more subframe n-k without the PDSCH of corresponding PDCCH '
ACK/NACK feedback.First seed type corresponds to following situations: where if there are PDCCH in the n-th-k subframes (wherein,
K can be one or more values), then emit in the n-th subframe and the ACK/NACK of the PDCCH is fed back.Second of type pair
It should be in following situations: where if receiving SRS hair in the n-th-k subframes of not other PDCCH after SPS activation
It penetrates, then regularly emits the ACK/NACK feedback for corresponding SPS transmitting in n-th of subframe.For related to SPS transmitting
Detailed description, can be with reference paper 3GPP TS 36.213.
It is substantially based on the CCE index of PDCCH and is used for what ACK/NACK was fed back in 8 system of LTE version to determine
PUCCH resource index.If the ACK/NACK response in a PUCCH in the n-th subframe includes in the n-th-k subframe
In one or more PDCCH (including general PDCCH and instruction DL SPS release PDCCH) ACK/NACK response,
It can then show that PUCCH resource is indexed from the CCE index of PDCCH.However, if should only emit in the n-th-k subframe
Not PDCCH SPS ACK/NACK response, then not can determine that for ACK/NACK response PUCCH resource index.For
Solution such problems is indicated for there is only ' not corresponding by RRC signaling in 8 system of LTE version in advance
The PUCCH resource indexed set of the case where PDSCH transmitting of PDCCH ' (that is, SPS PDSCH emits) is (for example, by four PUCCH
The set that resource index is constituted).Moreover, determining whether to make by the TPC field in the PDCCH of instruction SPS activation
With a PUCCH resource of PUCCH resource indexed set.It defines in the table 14 being shown below in the PUCCH for DL SPS
Resource index
Mapping relations between the value of TPC field.
[table 14]
If executing above-mentioned DL SPS transmitting in multicarrier support system, must provide in view of DL SPS emits
ACK/NACK launching technique.
The each embodiment of the invention to this is described under the premise of following: being similar to the above embodiments 4 and 5, for spy
Determine the PCell of UE the first PDCCH (with DAI=1 (DAI=1,2,3,4 ...) PDCCH) TPC field for original
The power control purpose of purpose, and the TPC field of other one or more PDCCH is used for ARI purpose.It is worth noting that,
Such hypothesis is that for clarity, and application example of the invention is without being limited thereto.I.e., it is possible to be mentioned by other methods
For ARI information.
When in the n-th subframe emit in the n-th-k subframe ' without corresponding PDCCH PDSCH transmitting ' (with
It is lower be known as ' the not SPS ' of PDCCH) ACK/NACK response when, the SPS of not PDCCH can be received in the n-th-k subframe,
And in addition to this it is possible to detect a PDCCH.Then, need to emit ACK/NACK for PDCCH in response to it is right
In the ACK/NACK response of the SPS of not PDCCH.Here, if a PDCCH detected is the first PDCCH (for example, tool
Have the PDCCH of DAI=1), then because the TPC field of PDCCH is used for original purpose, which is when UE does not receive ARI
When information.Therefore, UE not can determine that the resource index for PUCCH format 3.Hereinafter, description is used to solve the problems, such as above
Various embodiments of the present invention.
In the following description, ACK/NACK is needed to emit in one of three kinds of situations below.In short, situation 1 be for
' ACK/NACK of the PDSCH ' with PDCCH, situation 2 are for ' DL SPS discharges the ACK/NACK of PDCCH ', and situation
3 be for ' the ACK/NACK of DL SPS PDSCH '.
Situation 3 can be referred to as ' without the PDSCH ' of corresponding PDCCH, for ' the not ACK/ of the SPS ' of PDCCH
NACK or referred to as ' SPS ' ACK/NACK.In situation 1, ' PDCCH of the PDSCH ' with PDCCH can be referred to as
' the PDCCH ' corresponding to PDSCH.
Embodiment 6
Embodiment 6 is related to the method for always emitting ACK/NACK response using PUCCH format 3.
The 3 resource index collection of PUCCH format of SPS can be only used for UE instruction by RRC signaling.For example, can be to UE
There is provided about in the form of shown in the table 13 above byWithThe collection of composition
The information of conjunction.Furthermore it is possible to use PUCCH format 3 by the TPC field being used to indicate in the PUCCH that SPS is activated come specified
Which resource index of resource index collection.
As an example, may be selected and used logical when needing only to feed back the ACK/NACK of the SPS of not PDCCH
Cross specific 3 resource index of PUCCH format indicated by the SPS activation PDCCH in the set of RRC configuration.I.e., it is possible to use
PUCCH format 3 is only used for the ACK/NACK of the not SPS of PDCCH to emit.
As another example, method below can be applied to wherein need for ' not the SPS ' of PDCCH and
' there is the case where ACK/NACK of a PDSCH ' of PDCCH is fed back.
First method is selection and activates 3 resource index of PUCCH format indicated by PDCCH using by SPS.That is,
Also PUCCH format 3 can be used to emit for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH
NACK response.
According to whether ' including ARI information in the PDCCH ' corresponding to PDSCH, second method is further drawn at one
It is divided into two methods.
When one ' PDCCH ' corresponding to PDSCH be do not include ARI information PDCCH (for example, wherein the first DAI
(DAI=1) PDCCH) when, it may be selected and used and 3 resource index of PUCCH format indicated by PDCCH is activated by SPS.
That is, even if from ' PDCCH ' corresponding to PDSCH has not been obtained to ARI information, PUCCH format 3 also can be used emit for
' the not SPS ' of PDCCH and ' the ACK/NACK response of a PDSCH ' with PDCCH.
If one ' PDCCH ' corresponding to PDSCH be include ARI information PDCCH (such as without the first DAI (DAI
> 1) PDCCH) (this is it may is that when UE loss has the PDCCH of the first DAI), then it uses by ' corresponding to PDSCH's
3 resource index of PUCCH format of ARI value indicated by TPC field in PDCCH ' can be selected and be used.
Meanwhile when transmitting include for ' not the ACK/NACK of the SPS ' of PDCCH multiple ACK/NACK feedback when, can
By by the second or more PDCCH (for example, wherein one or more PDCCH of DAI > 1) on PCell or at one
Or ARI value indicated by the TPC field of one or more PDCCH on multiple SCell determines 3 resource index of PUCCH format.
Embodiment 7
Embodiment 7 is related to for operating for ' only ' always in fall-back mode not transmitting of the SPS of PDCCH
The method of ACK/NACK.Here, fall-back mode refers to being emitted according to the ACK/NACK of the operation defined in LTE version 8,
For example, the ACK/NACK using PUCCH format 1a/1b emits.On the other hand, about for ' not the SPS ' of PDCCH and its
The ACK/NACK transmitting of his DL transmitting (PDSCH with PDCCH), can be used PUCCH format 3.
For this purpose, can be used to emit the PUCCH format 1a/1b resource rope of ' only ' SPS to UE instruction by RRC signaling
Draw collection.It can configure as shown in table 14 or can be according to other arrangements PUCCH format 1a/1b resource index collection.Work as finger
When showing SPS activation, which that use PUCCH resource indexed set can be specified by activating the TPC field in PDCCH in SPS
A index.
Because having preset the time/frequency resource for SPS transmitting between BS and UE, BS and UE are aware of when to send out
It penetrates and receives for ' the not ACK/NACK feedback of the SPS ' of PDCCH.It therefore, is including bundle for the SPS of particular UE
It ties up in window, the TPC field of all PDCCH can be used to be used for ARI purpose, without between the PUCCH on PCell in BS
It distinguishes respectively.That is, including not no PDCCH during the transmitting that the ACK/NACK of the SPS only for not PDCCH is fed back
All TPC fields can be used to be used for ARI purpose in the one or more PDCCH emitted in the bundled window of SPS, without
It is distinguished between PCell and multiple SCell.
In this case, emit about PUCCH and the ACK/NACK of the SPS of not PDCCH is fed back, the TPC of PDCCH
Field is not used in original purpose (UL transmission power control).However, the TPC value in PDCCH is for previous transmission power
Opposite deviant, rather than absolute value, and even if UE does not update TPC value once or twice also keeps preset transmitting
Power.Other than using the transmission power control method of the TPC field in PDCCH, the power control of supplement is additionally provided
Method.Moreover, original purpose cannot be obtained by limiting UE when needing the not transmitting of the SPS of PDCCH in fdd mode
TPC value.Therefore, even if being operated described in the upper surface of present invention example in TDD when not applying the TPC of original purpose
Indistinctively influence network performance.
According to the example of embodiment 7, when needing only to feed back the ACK/NACK of the SPS of not PDCCH, Ke Yixuan
It selects and activates specific PUCCH format 1a/1b resource index indicated by PDCCH using the SPS of the set configured by RRC.That is,
For being only used for the ACK/NACK of the not SPS of PDCCH, it can execute and be operated using the fall-back mode of PUCCH format 1a/1b.
As another example, when a PDSCH's ' for needing that there is PDCCH for ' not the SPS ' of PDCCH and '
When ACK/NACK is fed back, as mentioned above the TPC field of all PDCCH in bundled window is used for ARI purpose, so can
To select and use PUCCH to format 3 resource ropes according to ARI value indicated by the TPC field of the PDCCH detected by one
Draw.
Meanwhile when transmitting includes multiple ACK/NACK feedback for the ACK/NACK of the SPS of not PDCCH, because
As described above the TPC field of all PDCCH in bundled window be used for ARI purpose, it is possible to by by PCell and/
Or one or more ARI values of the TPC field instruction of one or more PDCCH on SCell determine 3 resource of PUCCH format
Index.
Embodiment 8
Embodiment 8 is related to a kind of emitting the SPS of ' including ' not no PDCCH for always executing in fall-back mode
DL transmitting ACK/NACK method.
For this purpose, the PUCCH lattice of the not transmitting of the SPS of PDCCH can be used for " only " to UE instruction by RRC signaling
Formula 1a/1b resource index collection.PUCCH format 1a/1b can be configured or can configured according to other schemes as shown in table 14
Resource index collection.It, can be by activating the TPC field in PDCCH is specified to provide using PUCCH in SPS when indicating SPS activation
Which index of source indexed set.
It, can be with when needing for ' only ' not ACK/NACK feedback of the SPS of PDCCH according to the example of embodiment 8
It selects and activates specific PUCCH format 1a/1b resource index indicated by PDCCH using by the SPS of the RRC set configured.
That is, the fall-back mode using PUCCH format 1a/1b can be executed for the only not no ACK/NACK of the SPS of PDCCH.Here,
There can be the size of 1 or 2 bits according to the quantity of code word for the ACK/NACK feedback of the SPS of not PDCCH, and can
To use PUCCH format 1a or 1b.
As another example, need a PDSCH's ' for ' not the SPS ' of PDCCH and ' with PDCCH
ACK/NACK feedback may be selected and used and activate specific PUCCH lattice indicated by PDCCH by the SPS of the set of RRC configuration
Formula 1a/1b resource index.That is, being fed back even for the ACK/NACK for including the not transmitting of the SPS of PDCCH, can execute
Use the fall-back mode of PUCCH format 1a/1b.Here, there is one of PDCCH according to for ' not the SPS ' of PDCCH and '
The quantity of the code word of each of PDSCH ' and need 2 bits to 4 bit feedback payload (this is because ought non-application space
1 bit ACK/NACK Response field bit is generated about a code word when binding).
Hereinafter, by description when needs are for ' the not SPS ' of the PDCCH and ' ACK/ of a PDSCH ' with PDCCH
Detailed example of the invention when NACK is fed back.
Embodiment 8-1
Embodiment 8-1 is related to when a PDSCH's ' for needing to have PDCCH for ' not the SPS ' of PDCCH and '
ACK/NACK feed back when using M=2,3 or 4 channel selection profile method.That is, for ' the not SPS ' of PDCCH and ' tool
The size of the ACK/NACK feedback payload of a PDSCH ' of PDCCH is 2 to 4 bits, and for no any damage
Lost territory emits ACK/NACK feedback, can select using the channel of 2,3 or 4 PUCCH format 1b (or PUCCH format 1a)
Select scheme.When using the channel selection profile for being used for PUCCH format 1b (or 1a) defined in the LTE version 8, this can be with
It is expressed as operating under fall-back mode using the channel selection profile of LTE version 8.
In multiple resources for channel selection, from ' the CCE index of the PDCCH ' corresponding to PDSCH obtains one
PUCCH format 1b (or 1a) resource, and another PUCCH format can be indicated by being used to indicate the PDCCH of SPS activation
1b (or 1a).ACK/ can be emitted by the channel selection profile of one of two PUCCH format 1b (or 1a) resources of selection
Nack message.
In addition, if needing further exist for PUCCH resource (for example, M=3 or 4), and by " corresponding to PDSCH's
The corresponding PUCCH resource of value (CCE index+offset) that the CCE index of PDCCH " is obtained plus defined offset (for example, 1)
It can be used for channel selection.Replace or supplement based on ' the other resource of the CCE index of the PDCCH ' corresponding to PDSCH, with lead to
It is corresponding to cross the value for adding to defined offset (for example, 1) and obtaining by the resource index that SPS activates PDCCH to assign
PUCCH resource can be used for channel selection.
Alternatively, being similar to scheme above, following channel selection profiles can be applied, that is, use from ' not PDCCH
SPS ' and ' the PUCCH format 1a/1b resource that the relevant information of a PDSCH ' with PDCCH explicitly or implicitly determines
Index.
When UE determines the PUCCH resource for emitting ACK/NACK information according to embodiment 8-1, BS can attempt to connect
Receive about 3 region of PUCCH format, the region PUCCH format 1a/1b and the region channel selection (PUCCH format 1b (or 1a)) this three
The ACK/NACK information of kind situation.
Because any one of three kinds of situations can be used to emit ACK/NACK information in UE, BS should be above
Blind decoding is executed in the case of three kinds.
Embodiment 8-2
Embodiment 8-2 is related to a kind of when needs are for ' the not SPS ' of a PDCCH and ' PDSCH ' with PDCCH
ACK/NACK feedback when, use space binding (that is, for multiple code words ACK/NACK bundle), using in LTE version 8
The PUCCH format 1b (or 1a) of definition carrys out the method using fall-back mode.
Firstly, when ' not the SPS ' of PDCCH correspond to multiple (for example, 2) code words transmitting when, for its
ACK/NACK response executes space binding.Similarly, when ' PDSCH ' with PDCCH corresponds to multiple (for example, 2)
When the transmitting of code word, space binding is executed for the ACK/NACK response to it.If ' the SPS ' of PDCCH and ' do not had
The only one of a PDSCH ' of PDCCH is a code word transmitting and the other is two code words emit, then only about two
Code word transmitting bundlees to execute space.
Therefore, it makes comparisons with 2 to 4 bits when not executing space binding, when executing space binding, is used for
The size of the ACK/NACK payload of the PDSCH ' of ' not the SPS ' of PDCCH and ' with PDCCH is reduced to 2 ratios
It is special.
2 bit ACKs/NACK can be emitted by the PUCCH format 1b (or 1a) of traditional LTE version 8 to feed back.That is, if
Space binding is executed, then the PUCCH format 1b (or 1a) of LTE version 8 can be used, and that ACK/NACK is operated under fall-back mode is anti-
Feedback.
In such a case it is possible to select and use from one, ' the CCE rope of the PUCCH ' corresponding to PDSCH is extractive
PUCCH format 1a/1b resource index.Swashed alternatively, may be selected and used by the SPS that the resource index configured in RRC is concentrated
PUCCH format 1a/1b resource index indicated by PDCCH living.In other words, corresponding ACK/NACK response return back to PUCCH
Format 1a, and be re-used by phase rotation, that is, one of two ACK/NACK responses are mapped to I channel, and another
It is a to be mapped to Q channel.Alternatively, two ACK/NACK responses return back to PUCCH format 1b and are re-used.
For example, in dibit ACK/NACK used in PUCCH format 1b used in LTE version 8, most significant bit
(MSB) it can be mapped to for ' the not ACK/NACK of the SPS ' of PDCCH, and least significant bit (LSB) (LSB) can be reflected
It is mapped to for ' the ACK/NACK of a PDSCH ' with PDCCH (for example, PDCCH with DAI=1).Alternatively, can be with
The opposite mode of above example maps multiple ACK/NACK.
As another embodiment, for ' the ACK/NACK of the SPS ' of PDCCH is not mapped to the I of QPSK constellation
Axis, and for ' ACK/NACK of a PDSCH ' with PDCCH (for example, PDCCH with DAI=1) can be reflected
It is mapped to the Q axis of QPSK constellation.Alternatively, multiple ACK/NACK can be mapped in the mode opposite with above example.In addition,
According to the received timing of institute, for ' the not SPS ' of the PDCCH and ' ACK/ received first of a PDSCH ' with PDCCH
NACK is mapped to I axis, also, can be mapped to Q axis for received ACK/NACK later.Alternatively, can with it is upper
The example in face opposite mode maps multiple ACK/NACK.
For example, when for ' not the ACK/NACK of the SPS ' of PDCCH be mapped to I axis and ' have PDCCH (for example,
PDCCH with DAI=1) a PDSCH ' when being mapped to Q axis, even if UE fails to detect PDCCH (that is, ' corresponding to
The PDCCH ' of PDSCH), then BS can receive the ACK/NACK response at least SPS.This is because when UE fails to detect
When PDCCH, when for ' constellation positions when the ACK/NACK of the SPS ' of PDCCH is not mapped segment number I axis are equal to when use
PUCCH format 1a is emitted using BPSK constellation (that is, I axis) ' only ' for ' not when the ACK/NACK of the SPS ' of PDCCH
Constellation positions.
As another example, ' the 1,1' ' and ' 0 of QPSK constellation, 0 ' can be mapped to for ' not PDCCH
The ACK/NACK of SPS ', and ' 0,1' ' and ' 1,0 ' can be mapped to for ' with PDCCH (for example, having DAI=1's
PDCCH a PDSCH ' ACK/NACK).Alternatively, can be corresponding multiple to be mapped with the opposite mode of above example
ACK/NACK。
It is MIMO mould that constellation mapping above, which can be applied equally to the emission mode wherein in each cell,
The case where formula and other situations.Constellation mapping above can also be applied, and actually whether with application space binding is unrelated
(that is, unrelated with the presence or absence of the transmitting of 2 code words).
In Application Example 8-2, it might even be possible to feed back application to the ACK/NACK of ' only ' for the SPS of not PDCCH
Space binding.In this case, BS should execute blind decoding for following three kinds of situations: for the ACK/ for ' only ' SPS
The region PUCCH format 1a/1b of NACK, a PDSCH ' for having PDCCH for ' not the SPS ' of PDCCH and '
3 region of the region PUCCH format 1a/1b and PUCCH format of ACK/NACK.
In addition, replacing in Application Example 8-2 from ' the extractive resource of CCE rope of the PDCCH ' corresponding to PDSCH
Index is used as PUCCH resource, can be used and activates PUCCH specified by PDCCH by the SPS of the PUCCH resource collection of RRC configuration
Resource index, and other parts can be equally applied.
Embodiment 8-3
Embodiment 8-3 is related to when a PDSCH's ' for needing to have PDCCH for ' not the SPS ' of PDCCH and '
Application space binding (that is, the ACK/NACK for multiple code words is bundled) and the channel selection using M=2 when ACK/NACK is fed back
The method of scheme.When using the channel selection profile for being used for PUCCH format 1b (or 1a) defined in the LTE version 8, this can
To be expressed as the fall-back mode operation using the channel selection profile of LTE version 8.
Firstly, for ' not in the case where the transmitting of multiple (for example, two) code words of the SPS ' of PDCCH, for right
Its ACK/NACK response executes space binding.Similarly, for ' with PDCCH a PDSCH ' it is multiple (for example,
Two) in the case where the transmitting of code word, space binding is executed for the ACK/NACK response to it.If ' not PDCCH
SPS ' and ' with one of PDCCH PDSCH's ' first is that a code word and the other is two code words, then only for two codes
The transmitting of word executes space binding.
Therefore, the ACK/NACK payload of a PDSCH ' for ' not the SPS ' of PDCCH and ' with PDCCH
Size by from when do not execute space bundle when 2 bits to 4 bits be reduced to when execute space bundle when 2 bits.
2 bit ACKs/NACK feedback can be emitted by the PUCCH format 1b (or 1a) of traditional LTE version 8.Here,
It can be used using the channel selection profile of the M=2 of PUCCH1b (/ 1a).I.e., it is possible to returning using PUCCH format 1b (1a)
Mode is moved back to emit 2 bit ACKs as the result for executing space binding/NACK feedback.
Here, M=2 can indicate two kinds of ACK/NACK information (2 bit ACKs/NACK letter for bundling result as space
Breath) transmitting, or can indicate the channel selection using two PUCCH resources.It therefore, can be by using channel selection
To improve the detection performance of BS.
In two PUCCH resources for channel selection, the first PUCCH resource, which can be used, activates PDCCH by SPS
Specified PUCCH format 1a/1b resource index, and the second PUCCH resource can be used from ' the PDCCH ' corresponding to PDSCH
The extractive PUCCH format 1a/1b resource index of CCE rope.With above example on the contrary, the first and second PUCCH resources can
To be respectively mapped to by the SPS PUCCH resource index for activating PDCCH specified and from ' PDCCH's ' corresponding to PDSCH
The extractive PUCCH resource index of CCE rope.It can be selected by the channel of one of two PUCCH format 1b (or 1a) resources of selection
Scheme is selected to emit ACK/NACK information.
It in the present embodiment, can be configured for example as shown in table 5 or table 8 in ACK/NACK information and PUCCH resource
Between channel selection mapping relations.However, this is merely exemplary, and it can define and be mapped using new channel selection
Relationship.
Example as the embodiment, it is assumed that provide the channel mapping relations using PUCCH format 1b as shown in table 5.
Mapped for channel two PUCCH resources (With) in, it is provided by the PUCCH that SPS activates PDCCH specified
Source can be mapped toAlso, from ' the extractive PUCCH resource of the CCE rope of the PDCCH ' corresponding to PDSCH can be with
It is mapped toCan determine such mapping configuration, and with ' the not SPS ' of PDCCH and ' corresponding to PDCCH's
The reception sequence (receiving time) of PDSCH ' is unrelated.For example, even if when specific UE is losing PDCCH (i.e..' correspond to PDSCH
PDCCH ') and only receive when emitting response after SPS, UE, which also can receive, at least rings the ACK/NACK of the SPS
It answers.This is because when UE fails to detect PDCCH, for for ' the ACK/NACK of the SPS ' of PDCCH does not emit
PUCCH resourceWith the PUCCH resource for ' only ' for the ACK/NACK transmitting of the SPS of not PDCCHIt is identical.Meanwhile the modified example as this embodiment, it can be mapped on the contrary with above example or can be with
Corresponding PUCCH resource and DL emission type (PUCCH or SPS) are mapped according to the sequence of receiving time.
It, can will be in the channel mapping relations using PUCCH format 1b as another example of the present embodiment
The ACK/NACK of SPS is mapped to 2 bit ACKs/NACK MSB (that is, being mapped to the first bit for the ACK/NACK of SPS),
Also, for ' ACK/NACK of a PDSCH ' with PDCCH (for example, PDCCH with DAI=1) can be mapped
To LSB (that is, being mapped to the second bit for the ACK/NACK of the PDSCH with PDCCH).Alternatively, even if when for SPS
ACK/NACK be mapped to I axis and for ' a PDSCH ' with the PDCCH PDCCH of DAI=1 (for example, with)
ACK/NACK when being mapped to Q axis UE fail to detect PDCCH (that is, ' PDCCH ' corresponding to PDSCH), BS can also connect
Receive the ACK/NACK response at least SPS transmitting.This is because working as in the case where PUCCH is detected and failed for ' not having
The constellation positions when ACK/NACK of the SPS ' of PDCCH is mapped to I axis use PUCCH format 1a to use BPSK constellation with UE is worked as
(that is, I axis) come emit for ' only ' not the SPS of PDCCH ACK/NACK response when constellation positions it is identical.Alternatively, can be with
Configure mapping relations opposite with above example, and can the sequence of time based on the received execute mapping.
At least the ACK/NACK of SPS is responded in order to guarantee that BS is received, can feed back and emit in various ACK/NACK
In the case of specific information is mapped to specific PUCCH resource.For example, can be made with configurating channel Choose for user relationship for
The PUCCH resource that the ACK/NACK of SPS transmitting is mapped to and the PUCCH for emitting the ACK/NACK for ' only ' SPS thereon
Resource is identical.
Following table 15 shows modulation symbol (or the star for PUCCH format 1a and 1b in traditional LTE version 8/9
Seat).
[table 15]
In table 15, it is assumed that the value ' 0 ' of b (0) is NACK and ' 1 ' is ACK.So, the value ' 00 ' of (0) b, b (1) indicates
ACK/ACK, and ' 11 ' indicate NACK/NACK.In this case, at least one preceding bit b (0) have in PUCCH
Identical modulation symbol in format 1a and 1b.In other words, b (0) is when d (0)=1 in two PUCCH format 1a and 1b two
Always 0 in person, and when d (0)=- 1 always 1 in both two PUCCH formats 1a and 1b.Therefore, BS can receive and
The information about at least one preceding bit b (0) is detected, even if BS is not known whether using PUCCH format 1a or PUCCH
Format 1b received ACK/NACK feedback to emit.It can be with configurating channel Choose for user relationship, so that for ' there is no PDCCH
SPS ' ACK/NACK using being mapped to the PUCCH resource of a previous Bit b (0).Therefore, BS can guarantee at least right
In the reception of the ACK/NACK of SPS.
For example, it is interior as M=2, the channel selection mapping relations shown in following table 16 can be used.
[table 16]
In table 16, the ACK/NACK of SPS is mapped to HARQ-ACK (0), and for ' with PDCCH
The ACK/NACK of PDSCH ' can be mapped to HARQ-ACK (1).
For example, it is assumed that only receiving the SPS with a code word, and ' the PDSCH ' with PDCCH is not received.?
In this case, PUCCH format 1a can be used to emit the ACK/NACK response for SPS.
Meanwhile ' when there is the PDSCH ' of PDCCH, channel choosing according to the present invention can be used when receiving together with SPS
It selects.In this case, it is activated indicated by PDCCH by being concentrated through SPS in the PUCCH resource of the higher level configuration for SPS
PUCCH resource be used as table 16In addition, from ' the CCE index of the PDCCH ' corresponding to PDSCH (passes through
Pre-defined rule is implicitly) PUCCH resource that obtains is used as table 16In this case, BS should can connect
It receives and the ACK/NACK of SPS is responded, and whether lose that ' PDCCH ' corresponding to PDSCH is unrelated with UE.
As described above, being used if UE transmitting responds the ACK/NACK of SPSHere, ACK corresponds to
The wherein modulation symbol of b (0)=1 and d (0)=- 1, and NACK corresponds to the modulation symbol of wherein b (0)=0 and d (0)=1
Number.Meanwhile when UE transmitting ' when the ACK/NACK of the PDSCH ' with PDCCH is responded, can confirm for SPS and in table 16
Emit the resource of the ACK/NACK response for SPS on it.It will now be described using in table 16The case where
' ACK, NACK/DTX ' and ' NACK, NACK/DTX '.' ACK, NACK/DTX ' correspond to wherein b (0) b (1)=11 and d (0)=
1 modulation symbol, and ' NACK, NACK/DTX ' corresponds to the modulation symbol of wherein b (0) b (1)=00 and d (0)=1.Always
It, in the transmitting of the ACK/NACK response only for SPS and for SPS and ' the ACK/NACK response of the PDSCH ' with PDCCH
Transmitting the two in, sent out by identical modulation symbol (that is, for d (0)=- 1 of ACK and for the d (0)=1 of NACK)
It penetrates and is usingACK/NACK transmitting in for SPS ACK/NACK respond.Therefore, BS can detectedOn signal when confirmation at least the ACK/NACK of SPS is responded, and whether had been received for SPS's with BS
ACK/NACK response or for SPS and ' with PDCCH PDSCH ' ACK/NACK response it is unrelated.
Meanwhile in the case where the case where ' ACK, ACK ' in table 16 and ' NACK/DTX, ACK ', it can be used from ' right
It should be in the extractive resource of CCE rope of the PDCCH ' of PDSCH, that is, useTo emit ACK/NACK response.It is receiving
?On signal when, the PDSCH ' received for ' not the SPS ' of PDCCH and ' with PDCCH can be confirmed in BS
ACK/NACK response.
In the above example, although PUCCH format 1a has been described for convenience, same principle of the invention
PUCCH format 1b can be applied to.
It is, for example, possible to use PUCCH format 1b ' only ' to ring for having the ACK/NACK of the SPS there are two code word to emit
It answers.Meanwhile it ' when there is the PDSCH ' of PDCCH, can be used according to example according to the present invention empty when being received together with SPS
Between bundle.In both above situation, the ACK/ for SPS is emitted by same channel (PUCCH resource) and modulation symbol
Nack message.More specifically, (for example, logic product) is bundled by application space, the ACK/ACK of two code words for SPS,
ACK/NACK, NACK/ACK and NACK/NACK become ACK, NACK, NACK and NACK.If emitted simultaneously for SPS and ' tool
There is the ACK/NACK of the PDSCH ' of PDCCH to respond, then bundling result according to space for the ACK/NACK response of SPS becomes ACK
Or NACK, and respond respectively with for only SP ACK/NACK response channel and modulation symbol ACK/NACK and
NACK/NACK is identical.Therefore, signal is being detectedWhen, BS can be according to the previous signals (example for being at least used for SPS
Such as, (0) b) whether it is ACK or NACK and is whether space bundlees as a result, and received with BS by ACK/NACK response confirmation
To the ACK/NACK response for SPS or for SPS and ' have the ACK/NACK response of the PDSCH ' of PDCCH unrelated.
It is MIMO mould that constellation mapping above, which can be applied equally to the emission mode wherein in each cell,
The case where formula and other situations.Constellation mapping can also be applied, and actually whether with application space binding is unrelated (that is, with being
No there are the transmitting of 2 code words is unrelated).
In Application Example 8-3, it might even be possible to feed back transmitting to the ACK/NACK of ' only ' for the SPS of not PDCCH
Application space binding.It makes comparisons with embodiment 8-1 or 8-2, which, which can be reduced, wherein should execute blind Detecting by BS
The quantity in region.More specifically, the channel selection side in the channel selection profile defined in LTE version 8, for the M being worth greatly
Case is made of the superset of the channel selection profile of the M for small value.For example, one in the channel selection of M=2 was previously compared
Special (for example, b (0)) or the only transmitting of ACK/NACK have and use PUCCH format 1a in the case where not applying channel selection
The identical result of 1 bit ACK/NACK transmitting.Therefore, swash when by the SPS for the ACK/NACK for ' only ' SPS
It, can when PUCCH format 1a/1b resource index indicated by PDCCH living is used as the first resource index for channel selection
Wherein use channel selection the case where and wherein do not use channel selection the case where between distinguish.In this case, it detects
The ACK/NACK response of PDSCH ' for ' not the SPS ' of PDCCH and ' with PDCCH, it is automatic to detect ' only ' for SPS's
ACK/NACK response.Therefore, BS can execute blind Detecting in two regions, which is used for for channel selection
ACK/NACK in PUCCH format 1a/1b resource is detected and (is detected including the ACK/NACK of ' only ' for SPS) and is used for
ACK/NACK detection in PUCCH format 3.
Hereinafter, the detailed applications example that embodiment 8-3 will be described.
Embodiment 8-3-1
As described above, generating ACK/NACK response about three kinds of situations.Situation 1 is related to having corresponding PDCCH's
PDSCH, situation 2 is related to being used to indicate the PDCCH of DL SPS release, and situation 3 is related to no corresponding PDCCH's
PDSCH.Situation 3 is also referred to as the ACK/NACK for SPS PDSCH.
In the explanation of this embodiment, for ' PDCCH ' instruction situation 1 or situation 2 of ACK/NACK response, ' SPS
PDSCH ' indicates situation 3, and particular UE, which executes, to be received the DL of three kinds of situations above and execute ACK/ received for DL
The operation of NACK is illustrated.The ACK/NACK response emitted in n-th of UL subframe has in the n-th-k subframe about above
Relationship (wherein, k ∈ K, and K:{ k of three kinds of situations for the DL ACK/NACK response emitted0,k1,…kM-1, and refer to
Table 12).The explanation of ACK/NACK transmitting subframe position will be omitted below.
In this embodiment, in order to support the dynamic emission power as caused by TPC command without reducing performance, can make
With the predefined channel selection profile (defined in LTE version 8 or version 10) for passing through PUCCH format 1a.
The case where wherein configuring a serving cell, is described first now.
In this case, the use determination of TPC field is as follows.
The 2 bit TPC fields in the wherein PDCCH of DL DAI=1 are used for the TPC command of original purpose.
The 2 bit TPC fields in the PDCCH in DAI > 1 DL are used for ARI purpose.UE is it is assumed that DAI > 1 DL wherein
In all PDCCH in, ARI value is identical.
In addition, the use of PUCCH format be determined it is as follows.
If UE only receives SPS PDSCH, using LTE version 8PUCCH format 1a/1b resource (that is, in rollback mould
Operation in formula).
If UE receives a PDCCH of wherein DL DAI=1, LTE version 8PUCCH format 1a/1b resource is used
(that is, operation in fall-back mode).
If UE receives SPS PDSCH and another PDCCH with DL DAI=1, using passing through PUCCH format
The predefined channel selection profile (channel selection profile defined in LTE version 8 and version 10) of 1a.Here, by higher
Layer configuration is to determine the first PUCCH resource (for example, referring to by the ARI by SPS PDCCH in the resource set that RRC is configured
The resource shown), and the first CCE based on the transmitting for corresponding PDCCH (that is, the wherein PDCCH of DAI=1 DL)
(or index) is numbered to determine the 2nd PUCCH resource.
In other cases, PUCCH format 3 is used as the PUCCH format of configuration.
Meanwhile the case where wherein configuring multiple serving cells will now be described.
Here, the use of TPC field be determined it is as follows.
It is ordered in the TPC that wherein only the 2 bit TPC fields on PCell in the PDCCH of DL DAI=1 are used for original purpose
It enables.
The 2 bit TPC fields of every other one or more PDCCH on PCell and one or more SCell are used
In the TPC command of original purpose.UE assumes in all one or more PDCCH on PCell and one or more SCell,
ARI value is identical.
In addition, the use of PUCCH format be determined it is as follows.
If UE only receives SPS PDSCH, using LTE version 8PUCCH format 1a/1b resource (that is, in rollback mould
Operation in formula).
If UE receives a PDCCH of wherein DL DAI=1, LTE version 8PUCCH format 1a/1b resource is used
(that is, operation in fall-back mode).
If UE only receives SPS PDSCH and wherein another PDCCH of DL DAI=1 on PCell, using logical
Cross the predefined channel selection profile (channel selection profile defined in LTE version 8 or version 10) of PUCCH format 1a.?
This, by higher level configuration (for example, by activating resource indicated by the ARI of PDCCH as SPS in the resource set that RRC is configured
(referring to table 14)) determine the first PUCCH resource, also, based on for corresponding PDCCH (that is, wherein DL DAI=1
The number (or index) of first CCE of transmitting PDCCH) determines the second PUCCH resource.
In other cases, PUCCH format 3 is used as the PUCCH format of configuration.
Embodiment 8-3-2
In the explanation of this embodiment, ' PDCCH ' instruction situation 1 relevant to ACK/NACK response or situation 2, and
' SPS PDSCH ' indicates situation 3, as described in example 8 above -3-1.Term ' PDSCH ' or ' tool with DAI=1
The PDSCH ' of DAI > 1 DL refer to by corresponding to PDSCH PDCCH indicated by DL DAI be 1 or be greater than 1.Below
The explanation of ACK/NACK transmitting subframe position will be omitted.
If UE receives SPS PDSCH and the PDCCH with DL DAI=1, because there is no ARI information, UE
Available PUCCH resource is not can know that.In order to solve this problem, it may be considered that method below.
The case where wherein using the channel selection of the M=2 in LTE version 8, is described first now.
If UE only receives SPS PDSCH and PDSCH with DL DAI=1 and does not receive with DAI > 1 DL
PDSCH, then UE is while bundling the application space PDSCH through the TDD channel selection of the M=2 in LTE version 8
To emit ACK/NACK.When using LTE version 8TDD channel selection, UE emits two ACK/NACK bits.Here, can be with
It is selected using in the channel selection mapping relations (for example, table 5 above to 7) in LTE version 8 and the channel in LTE version 10
One of mapping relations (for example, table 8 above to 11) are selected, and this can be determined by RRC configuration.
In application 8 channel selection of LTE version, by SPS PUCCH resource (that is, the resource set configured by higher level
SPS activation PDCCH indicated by resource, referring to table 14) determineValue.In addition, HARQ-ACK (0) be for
The ACK/NACK/DTX response of SPS PDSCH transmitting.This is the feelings in order to solve wherein PDSCH of the UE loss with DAI=1
The ambiguity of condition and can definitely emit for SPS transmitting ACK/NACK response.
In this case, the TPC field of the PDCCH with DL DAI=1 can be practically used for PUCCH power control.
However, the loss of ACK/NACK bit may be due to for having in the cell for supporting MIMO transmitting (or the transmitting of 2 code words)
The space of the PDSCH of DAI=1 bundlees and occurs.
Simultaneously, it may be considered that the case where wherein using PUCCH format 3.
If UE receives both SPS PDSCH and the PDSCH with DL DAI=1, UE be can be assumed with DL
The TPC field of the PDCCH of DAI=1 is used for ARI purpose.Then, UE PUCCH format 3 can be used emit 2 bit ACKs/
NACK (in non-MIMO cell) or 3 bit ACKs/NACK (in MIMO cell).
In this case, because not applying ACK/NACK to bundle, it is possible to emit ACK/NACK bit, without ACK/
The loss of nack message.Meanwhile because there is no the TPC fields for original TPC command purpose (because having DL DAI=1
PDCCH TPC field be used for ARI purpose), it is possible that improperly execute PUCCH power control.
In view of the situation, propose following two methods come in CA for the resource of TDD PUCCH format 3
Distribution.
First method is the resource allocation reused in CA for FDD PUCCH format 3.In this case, exist
One or more TPC fields on PCell can be used for original purpose, and one or more on one or more SCell
A TPC field can be used for ARI purpose.If UE only receives PDSCH on PCell, can be used in LTE version 8
Defined in ACK/NACK binding.
Second method is the money reused when not supporting CA (that is, in non-CA) for TDD PUCCH format 3
Source distribution.So, the TPC field of the PDCCH with DAI=1 on PCell can be used for original purpose, and
The TPC field of every other PDCCH on PCell and SCell can be used for ARI purpose.When UE is only received on PCell
When SPS PDSCH or PDCCH with DL DAI=1, LTE version 8PUCCH format 1a/1b can be used (that is, fall-back mode
Operation).It does not receive when UE receives SPS PDSCH and PDSCH with DL DAI=1 but with DAI > 1 DL
When PDSCH, 8 channel selection of LTE version is used.
Emitted in a tdd system by the ACK/NACK of PUCCH
ACK/NACK binding method and resource allocation methods in LTE-A (or LTE version 1) are described.
For using ACK/NACK feedback of the PUCCH format 3 in TDD, defining mode 1 and mode 2.Mode 1 can prop up
Hold the ACK/NACK payload size until 20 bits.If the quantity of indicated ACK/NACK bit is more than 20, make
It is bundled with space.If the quantity of the ACK/NACK bit indicated in mode 1 less than 20, is not supported to bundle.Meanwhile mode
2 be the scheme that (binding in the time domain or the binding in the domain CC) is wherein bundled with space binding together application obscure portions.That is,
In mode 2, if the quantity of indicated ACK/NACK bit is more than x, space binding is simultaneously executed with part binding.
When to ACK/NACK feedback of the PUCCH format 1b in TDD is used using channel selection, define mode a and
Mode b.Mode a is the scheme for not supporting any binding when the quantity of indicated ACK/NACK bit is less than 4 wherein.Mould
Formula b is wherein to bundle with space binding together application obscure portions (in time domain when the quantity of indicated ACK/NACK bit is more than 4
In binding or the binding in the domain CC) scheme.
On the other hand, the resource allocation of PUCCH format 3 is defined as foloows.It is corresponding with PDSCH on PCell
2 bit TPC fields in PDCCH are used for the TPC command of original purpose.2 of PDCCH corresponding with PDSCH on SCell
Bit TPC field is used for ARI purpose.If not receiving the PDCCH corresponding with PDSCH on SCell and receiving
PDSCH on PCell then uses PUCCH 1a/1b by the scheme defined in LTE version 8.
Hereinafter, by describing when only there are the ACK/NACK binding methods and resource allocation methods when DL reception on PCell.
Embodiment 9
Embodiment 9 is related to the binding of space in mode 1.
Mode 1 for TDD can be supported until the independent ACK/NACK of 20 bits emits.However, if indicated
The quantity of ACK/NACK bit is more than 20, then needs application space to bundle.Because uncertain feedback is only when application space binding
Vertical ACK/NACK information, it is possible that reducing the efficiency of HARQ operation, and therefore, it is necessary to maximally emit individually
ACK/NACK information, without bundling.That is, space bundlees the simple application to all ACK/NACK bits in DL throughput performance
On be undesirable.Moreover, because mode 1 is to emit the scheme of independent ACK/NACK feedback in the case where no change,
So should minimally bundle application space.Therefore, it is necessary to execute space binding, so that the quantity of ACK/NACK bit is closest
20 but it is less than 20.
It is explained below when the quantity of indicated ACK/NACK bit is more than 20 for execute space binding it is detailed
Method.
As first method, it may be considered that the space binding of (CC one by one) as unit of CC.According to first method, Ke Yi
Application space bundlees in all DL subframes in one specific CC.In this way it is possible to run through all subframes about other CC
Space binding is executed, until wanting the quantity of the ACK/NACK bit of actual transmission less than 20.It is assumed that more frequently relative to SCell
PCell is dispatched, it can the finally application space binding on PCell.
When TDD is configured as 9DL:1UL (that is, emitting in a UL subframe for sending out for the DL in 9 DL subframes
The configuration of the ACK/NACK penetrated, for example, with reference to the subframe 2 of the UL-DL configuration 5 of table 12) when, if the quantity of the CC of configuration is super
2 are crossed, even if then space binding is applied to all CC, ACK/NACK payload size is also above 20 bits.Therefore, when matching
When the quantity of the CC set is 2, it can be bundled to all application spaces CC.
When TDD configuration is not 9DL:1UL, (or highest index) is indexed with the last one to from logic indexes
CC acts start, tool, and there are two (the N of the code word configuredconfiguredDLsubframe+NCW_SF- 9) a application space CC binding.It can be with
Finally to the binding of the application space PCell (i.e., it is possible to assigning minimum logic index to PCell).Here,
NconfiguredDLsubframeIt is the quantity of wherein feeding back ACK/NACK DL subframe on a CC.NCW_SFIt is the sum of code word, it is right
In these code words, on all DL CC in a subframe feeding back ACK/NACK.I.e., it is possible to determine as shown in equation 2
NCW_SF。
[equation 2]
In equation 2, NCW,iIt is the quantity of the code word configured on i-th of CC.
As second method, it may be considered that the space binding of (subframe one by one) as unit of subframe.It, can according to second method
It is bundled with application space on all CC in a specific DL subframe.In this way it is possible to run through about other DL subframes
All CC execute space binding, until want actual transmission ACK/NACK bit quantity less than 20.
According to above-mentioned first or second method, the quantity of the ACK/NACK bit of binding is 18,19 or 20.According to right
In the quantity of the CC of UE configuration, the ACK/NACK bit when application first or second method is shown in following table 17
Quantity.
[table 17]
First method can maximally support that the independent ACK/NACK for PCell emits relative to second method, and
It can be easily expressed.If the quantity of indicated ACK/NACK bit is more than 20, it is preferably, holds to CC one by one
Row space bundlees (that is, using first method).
Embodiment 10
In embodiment 10, the detailed applications example of above-mentioned mode 2 and mode b is described.Mode 2 is wherein and for making
With the space binding of ACK/NACK feedback of the PUCCH format 3 in TDD together application obscure portions binding (binding in the time domain or
Binding in the domain CC) scheme.Mode b is wherein when in the case where the quantity of indicated ACK/NACK bit is more than 4
Using when channel selection and for using the space of ACK/NACK feedback of the PUCCH format 1b in TDD to bundle application section together
Divide the scheme of binding (binding in the time domain or the binding in the domain CC).
Mode 2 can valuably be used to improve the ACK/NACK performance of the UE about power limited.It is straight when that will support
To 10 bits ACK/NACK FDD with support that TDD has more than FDD until when the TDD of ACK/NACK of 20 bits makes comparisons
Small UL covering.In addition, mode 1 is (wherein, when indicated when the quantity of the DL CC in TDD 9DL-1UL configuration is more than 2
The quantity of ACK/NACK bit bundle application space when being more than 20, and when the quantity of indicated ACK/NACK bit is 20
Or application space does not bundle when less) ACK/NACK cannot be supported to feed back.For example, in order to support on 5 DL CC and in TDD
ACK/NACK feedback in 9DL-1UL configuration, needs 45 ACK/NACK bits in total, even if application space bundlees.Therefore,
In order at least support ACK/NACK feedback in TDD 9DL-1UL configuration, the above-mentioned mode for PUCCH format 3 is needed support
2。
Hereinafter, will be described in bundling to the space that mode 2 and mode b are applied.
Embodiment 10-1
In embodiment 10-1, space binding in the time domain is described.Other than the binding of space, it can also execute
Time domain binding in this embodiment.
Can execute as space binding time domain binding, without in addition modify on each CC in LTE version 8
Defined in 2 bit DAI.Moreover, can simply be bundled using time domain on each CC in application time domain binding, and
It need not consider various forms of CA.That is, determining that the time domain binding method of the various situations for CA is that it is enough.Because as time domain
The size of the ACK/NACK information bit using result of binding is 10 bits, it is possible to by the PUCCH lattice of LTE version 10
3 structure of formula is used as the PUCCH format that be used for ACK/NACK transmitting.
PDCCH about all distribution sequentially increases DAI value.Therefore, when using DAI, UE cannot be identified to be tied in time domain
Tie up the case where the last one PDCCH is lost in window.In order to solve this problem, for finally detecting on each CC
The DAI value of PDCCH can be input into ACK/NACK mapper, and then be encoded.
Figure 40 is the figure of illustrative exemplary domain portion binding.4 subframes in the example of Figure 40, on each CC
Upper application ACK/NACK binding.
In the first CC of Figure 40, UE has been received PDCCH with DAI=0 in the first subframe and second
The PDCCH with DAI=1 in subframe, but the PDCCH with DAI=2 in third subframe is received not yet.So
Afterwards, because UE does not know whether to have transmitted the last one PDCCH (DAI=2), UE can be identified and be had been received
All PDCCH in time domain bundled window.In addition, Figure 40 shows following situations, wherein be successfully decoded (that is, ACK) by connecing
Each of the PDSCH of the PDCCH scheduling of receipts, and as a result, generate ACK/NACK information of the ACK as binding.With institute
Together, UE can encode last received DAI value to the ACK information of generation, that is, DAI=1.UE coding and transmitting ACK and DAI
(DAI=1), and then, BS can identify that UE has lost PDCCH (DAI=2).
The time domain bundling operation on the 2nd CC of Figure 40 is similar on the first CC.UE can will be last received
DAI value (that is, DAI=0) encodes together with ACK information.Because UE encodes and emit ACK and DAI (DAI=0), BS can be with
Identification UE has lost PDCCH (DAI=1).
In the 3rd CC of Figure 40, UE receives the PDCCH (DAI=0) in the first subframe, and receives
PDCCH (DAI=2) in three subframes.Even if the transmitting of the unidentified PDCCH (DAI=1) in the second subframe out of UE, UE can
To identify that itself has lost PDCCH (DAI=1) because the DAI value of received PDCCH do not increase sequentially.Although Figure 40
Show wherein be successfully decoded (that is, ACK) by received PDCCH scheduling PDSCH each the case where, but UE
ACK/NACK information there may be NACK as binding, because having lost the transmitting of a PDCCH.
In the 4th CC of Figure 40, UE only receives PDCCH (DAI=0), and is dispatched being successfully decoded by PDCCH
PDSCH when generate ACK information.Generated ACK information and last received DAI value (DAI=0) can be encoded together.
In the 5th CC of Figure 40, UE only receives the PDCCH with DAI=0.UE does not know in the 4th subframe
In transmit the PDCCH with DAI=1.Figure 40 show wherein not successfully decoding (that is, NACK) pass through it is received by UE
PDSCH scheduled in PDCCH.Therefore, UE can produce nack message.
Therefore, when domain space bundlees when applicable, 2 bit TDD of LTE version 8 can be reused on each CC
DAI (that is, as PDCCH stored counts device) is without modification.
The example of PUCCH format 3 as the application for mode 2 can be compiled being defined on channel as shown in table 18
The ACK/NACK state of each CC before code.
[table 18]
DAI value using the ACK/NACK state of table 18, with the last received PDCCH on each of Figure 40 CC
The result of the ACK/NACK of binding encoded is expressed as follows together: ' 01 (DAI=1) ' on the first CC, in the 2nd CC
On ' 01 (DAI=0) ', ' 11 (NACK) ' on the 3rd CC, five CC of ' 00 (DAI=0) ' He on the 4th CC
On ' 11 (NACK) '.
The ACK/NACK for 5 CC before executing channel coding in the PUCCH format 3 that mode 2 is applied to has
The polymerization for imitating load is ' 0100110011 '.
The principle of the present invention for above-mentioned mode 2 can be applied equally to mode b.Application for mode b,
Channel selection mapping relations (mapping relations between PUCCH resource and ACK/NACK bit) and NACK/ can be defined on
Relationship between DAI value.
Therefore, when being bundled using time domain, each ACK/NACK response on each CC can be expressed as tying
Tie up ACK/NACK information.
Embodiment 10-2
In embodiment 10-2, the binding of CC domain space is described.Other than the binding of space, it can execute in this implementation
Time domain binding in example.
The domain CC binding in, it is preferred that use DAI as indicate in a subframe in the binding being made of multiple CC
The indicator of the sum of the PDSCH (or corresponding PDCCH) dispatched in window, rather than use DAI as on each CC
The stored counts device of the PDSCH (or corresponding PDCCH) dispatched in multiple subframes is as in conventional DAI.This is because
When DAI indicates the sum of PDSCH (or PDCCH) of each subframe, it is not necessary to provide and be abandoned in time most for wherein UE
The solution of the case where the latter PDCCH.
Then, UE can be equal to when the quantity for emitting generated ACK for the DL being successfully decoded in bundled window
Emit ACK when the sum of PDSCH (or PDCCH) in bundled window, and otherwise, UE emits NACK (at this point, DTX is expressed as
NACK)。
Hereinafter, will be described in the domain CC bundlees application to mode b and mode 2.
It is described with reference to Figure 41 the channel selection for bundling to the domain application CC mode b.
In this case, it generally assumes that and is closed using the channel selection mapping of LTE version 10 (for example, table 8 above to 11)
System.
If, can using the ACK/NACK PUCCH resource for implicitly determining (that is, obtaining from the CCE index of PDCCH)
To select to provide with the PUCCH of the PDCCH dynamic link for the scheduling on PCC (or PCell) first in each subframe
Source.
If only dispatching PDSCH on PCC (or PCell) in more CC configuration, can apply in LTE version 8
ACK/NACK resource impact (for example, table 5 above to 7).I.e., it is possible to execute the operation of the fall-back mode in LTE version 8.
In the example of Figure 41, it is assumed that configure two cells (PCC and SCell) in each subframe.
In the TDD 2DL:1UL configuration of Figure 41, in the first subframe because PDSCH it is scheduled on PCC and
It is scheduled on SCC, so determining PUCCH resource from the CCE index of the PDCCH for dispatching SCC PDSCH.In the second son
In frame, PUCCH resource can be determined from the CCE index of the PDCCH for dispatching PCC PDSCH.Such PUCCH can be used
Resource is come using channel selection operations.It is, for example, possible to use channel selection mapping relations as shown in table 8 to execute ACK/
NACK transmitting.
In TDD 3DL:1UL configuration, PDSCH is only dispatched on PCC in all subframes.In such a case it is possible to such as
The upper execution fall-back mode operation.It is, for example, possible to use channel selection mapping relations as shown in Table 6 to pass through
PUCCH format 1b executes ACK/NACK transmitting.
It, can because dispatching PDSCH on both PCC and SCC in the first subframe in TDD 4DL:1UL configuration
To determine PUCCH resource based on the CCE index of the PDCCH for dispatching the PDSCH on PCC.Because PDSCH is second
It is scheduled and only scheduled on a cell (PCC or SCC) in the third and fourth subframe in subframe, it is possible to base
PUCCH resource is determined in the CCE index of the PDCCH of corresponding PDSCH.In this way it is possible to use identified PUCCH
Resource executes channel selection operations.It is, for example, possible to use the channel selection mapping relations shown in table 10 to execute ACK/
NACK transmitting.
The example bundled to the application of mode 2 domain CC is described with reference to Figure 42.
In the example of Figure 42, it is assumed that the maximum quantity of ACK/NACK bit is 12, and maximum bundled window be 2 (that is,
It include most two CC in a bundled window).
In order to keep independent ACK/NACK to emit, gradually application binding, until the quantity of ACK/NACK bit is closest
12 and less than 12.
In addition, not including PCell (or PCC) in bundled window.That is, only configuring bundled window for SCell (SCC).
Bundled window can be applied with the ascending order of CC index.
As shown in Figure 42, the domain CC binding can gradually apply bundled window (being made of 2 CC), until ACK/
The quantity (quantity of the ACK/NACK bit after the binding of application space) of NACK bit becomes 12 or less.
In the 2DL:1UL configuration of Figure 42, because the quantity of the ACK/NACK bit after executing space binding is 10,
So not configuring bundled window.
In 3DL:1UL configuration, because the quantity of the ACK/NACK bit after executing space binding is 15, configuration
Bundled window.The quantity of ACK/NACK bit after the bundled window for being configured to two CC (SCC3 and SCC4) is 12, and
And therefore, it is not reconfigured bundled window.
In the 4DL:1UL configuration of Figure 42, because the quantity of the ACK/NACK bit after executing space binding is 20,
So configuration bundled window.When being configured to the bundled window of two CC (SCC3 and SCC4), 16 bit ACKs/NACK is generated,
And therefore, configure another bundled window.If configuring another bundled window for two CC (SCC1 and SCC2), produce
Raw 12 bit ACKs/NACK, and therefore, it is not reconfigured bundled window.
Therefore, when being bundled using the domain CC part, for the binding knot of all ACK/NACK bits in bundled window
Fruit (for example, result of logic and operation) is launched as ACK/NACK information.DAI in PDCCH is indicated in a subframe
In the sum of PDSCH dispatched on all CC.The largest amount for being used for the bundled window of PUCCH format 3 can be determined as 2
(that is, most two CC (or cell) can configure a bundled window).
Embodiment 11
Embodiment 11 is related to passing through when only receiving PDCCH/PDSCH on PCell (hereinafter referred to as only PCell reception)
The ACK/NACK launching technique of PUCCH format 3.Particularly, the only PCell being described in detail in TDD is received.
When not received on SCell and only receiving the PDCCH corresponding to PDSCH on PCell, can make
With the PUCCH format 1a/1b resource (i.e., it is possible to being run in fall-back mode) of LTE version 8.
In fdd, can using fall-back mode with for use the PUCCH resource defined in LTE version 8 purpose and
The purpose for clearly determining PUCCH resource, even if not receiving ARI on SCell.
If TPC field is for the ARI purpose on SCell, ACK/NACK resource may be in only PCell reception condition
It is lower fuzzy.In order to solve this problem, the multiplexing of the ACK/NACK defined in LTE version 8TDD system or ACK/ can be applied
NACK binding.However, some ACK/NACK information cannot be emitted if bundled using ACK/NACK binding or time domain, and
Thus, it is possible to create the considerable damage of DL handling capacity.Moreover, because carrying out lap with ACK/NACK mapping relations
ACK/NACK state, there is no assurance that 4 bit ACKs/NACK ACK/NACK performance in LTE version 8TDD system.
Therefore, set forth below is the ACK/NACK launching techniques for only PCell reception condition.
Embodiment 11-1
According to this embodiment, it when receiving single PDSCH on PCell, can be used defined in the LTE version 8
The resource of PUCCH format 1a/1b.In such a case it is possible to which the use of DAI and ARI are defined as follows.
Figure 43 is the exemplary figure used for illustrating DAI and TPC.
As shown in Figure 43, as in LTE version 8TDD system, the DAI on PCell is used as PDCCH
The stored counts device of (or PDSCH).As in LTE version 8TDD system, the DAI on SCell is used as PDCCH
The stored counts device of (or PDSCH).DAI on SCell can be configured as ' 00 '.In the diagram example of Figure 43,
The DAI value of the PDCCH of SCell is all configured as ' 00 '.If the DAI value of the PDCCH on SCell be configured identically for
' 00 ', then PDCCH DCI can also be dispatched in public search space with imperial edict.In terms of UE realization, predefined value ' 00 ' can be with
It is used as virtual CRC (that is, for error detection when DAI value is not ' 00 ').
As shown in Figure 43, the TPC word of the PDCCH (that is, PDCCH with DAI=00) distributed first on PCell
Section is used for the TPC command of original purpose.Every other PDCCH other than the PDCCH with DAI=00 on PCell
The TPC field of (including PCell and SCell) is used for ARI purpose, and the field for ARI purpose in PDCCH should be in institute
Value having the same in some PDCCH.
UE behavior in this case can be defined as foloows.
If there are the PDSCH of no corresponding PDCCH to emit (that is, only SPS PDSCH) on PCell,
If √ emits without other PDSCH,
● use LTE version 8PUCCH format 1a/1b.
√ otherwise,
● use PUCCH format 3.
Exceptionally, ARI will be used as in the TPC field in the PDCCH with DAI=' 00 '.
Otherwise
If √, which has the single PDSCH with DAI=' 00 ' on PCell or exists on PCell, is used to indicate DL

Embodiment 13
Embodiment 13 is related to one kind according to whether there are SPS PDSCH to carry out the method using different TPC fields.
As described above, generating ACK/NACK response about three kinds of situations.Situation 1 is related to having corresponding PDCCH's
PDSCH, situation 2 is related to indicating the PDCCH of DL SPS release, and situation 3 is related to the PDSCH of no corresponding PDCCH.Situation
3 also referred to as the ACK/NACK of SPS PDSCH.
In the explanation of the embodiment, situation 1 or situation 2 are indicated for ' PDCCH ' relevant to ACK/NACK response,
' SPS PDSCH ' indicates situation 3, and particular UE, which is executed, to be received and execute received for DL for the DL of three kinds of situations above
The operation of ACK/NACK is illustrated.The ACK/NACK response emitted in n-th of UL subframe has in the n-th-k subframe (its
In, k ∈ K and K:{ k0,k1,…kM-1, and referring to table 12) in the ACK/NACK of the DL transmitting of three kinds of situations above is rung
The relationship answered.Hereinafter, the explanation that ACK/NACK transmitting subframe position will be omitted.
If emitting ACK/NACK from UE by various formats, answering for the blind decoding of BS explanation ACK/NACK is increased
Miscellaneous degree.In order to improve the performance in BS, such as complicated blind decoding, and in order to resource is efficiently used, can be used by
The PUCCH format of higher level configuration.Hereinafter, will be described in depending on whether there are SPS PDSCH and use different TPC
The method of field.
It, can be as follows by the use of (2 bit) TPC field determination when configuring a serving cell.When there are SPS
When PDSCH, the TPC field in all PDCCH can be used as ARI, and UE can be assumed ARI value all
It is identical in PDCCH.Meanwhile if there is no SPS PDSCH, then the TPC field of the PDCCH with DL DAI=1 can be used for
Original TPC command, and the TPC field of the PDCCH with DAI > 1 DL is used as ARI.UE can be assumed with DL
ARI value in all PDCCH of DAI > 1 is identical.
In addition, when configuring a serving cell, it can be as follows by the use of PUCCH format determination.If UE ' is only ' it connects
SPS PDSCH is received, then LTE version 8PUCCH format 1a/1b can be used.Alternatively, if UE ' only ' receive with DL
LTE version 8PUCCH format 1a/1b then can be used in the single PDCCH of DAI=1.It in other cases, can be by PUCCH
Format 3 is used as the PUCCH format configured by higher level.
If DL DAI is used as simple counter (PDCCH stored counts device), the TDD PUCCH format 3 in CA
Resource allocation can be identical as the resource allocation in single carrier wave (or non-CA).That is, being used for the resource allocation side of PCell
Method identical with the resource allocation methods in non-CA can be used in method.It in the case of a ca, can will be for multiple cells
PUCCH resource distribution determination it is as follows.
It, can be as follows by the use of TPC field determination if configuring more than one serving cell.When there are SPS
When PDSCH, the TPC field of all PDCCH on PCell and one or more SCell can be used for ARI purpose, and
UE can be assumed identical with the ARI value on all PDCCH on one or more SCell in PCell.Meanwhile if there is no
SPS PDSCH, then only the TPC field of the PDCCH with DL DAI=1 on PCell can be used for original TPC command,
And the TPC field of the every other PDCCH on PCell and one or more SCell can be used for ARI purpose.UE can be with
It is assumed that identical with the ARI value on all PDCCH on one or more SCell in PCell.
If configuring more than one serving cell, the purposes of PUCCH format can be used as follows.If UE ' is only ' it connects
SPS PDSCH is received, then LTE version 8PUCCH format 1a/1b can be used.Alternatively, if UE ' only ' receive with DL
LTE version 8PUCCH format 1a/1b then can be used in the single PDCCH of DAI=1.It, can be by PUCCH for other situations
Format 3 is used as the PUCCH format configured by higher level.
Embodiment 14
Embodiment 14 is related to PUCCH money in view of above-described embodiment, for TDD HARG ACK/NACK response transmitting
Source distribution method.
In traditional 8/9 system of LTE version, because to the ACK/NACK for being more than regulation bit size (for example, 4 bits)
Transmitting is using ACK/NACK binding (space binding and/or time domain binding), so having produced independent ACK/NACK information
Loss.In LTE version 10 (or LTE-A) system, PUCCH format 3 is designed to support the independent ACK/ until 20 bits
The transmitting of nack message.In CA and/or TDD support system, because wherein emitting the feelings of the ACK/NACK of 20 bits or more
Condition is likely to occur, so needing the method for effectively utilizing resource while emitting ACK/NACK information without loss.
Figure 45 is the exemplary figure of the invention used illustrated for the TPC field in PDCCH.In the example of Figure 45
In, ARI is information of the instruction for the resource of the PUCCH format 3 of ACK/NACK transmitting.Although there is DL on PCell
The TPC field of the PDCCH of DAI=1 is used for original TPC command, but the TPC of other PDCCH on PCell and SCell
Field is used as ARI.UE can be assumed that the ARI value on PCell and SCell is identical.Therefore, even if only detecting an ARI,
It can also determine the resource of PUCCH format 3.
When TPC field is re-used as ARI, the precision of PUCCH power control may be decreased.However, because can lead to
ARI information is crossed certainly to determine the resource of PUCCH format 3, so relative to the drop in the precision of PUCCH power control
It is low, it the use of the transmitting of lossy ACK/NACK information that do not have of PUCCH format 3 may be preferred for whole system.
In the example of Figure 45, when UE success at least one PDCCH of detection including ARI, it can be used by ARI
The PUCCH format 3 of instruction responds to emit ACK/NACK.However, if UE ' only ' detect not ARI PDCCH (that is,
The PDCCH with DAI=1 on PCell), then UE cannot obtain ARI information, and not can determine that 3 resource of PUCCH format.
In such a case it is possible to using conventional form, i.e. the PUCCH format 1a/1b of LTE version 8/9 emits without information loss
ACK/NACK response.
It is, therefore, possible to provide a kind of resource allocation methods, this method can emit without any loss at one or
The ACK/NACK response of the DL transmitting (PDCCH and/or PDSCH) emitted in multiple DL subframes.In addition, because with CA or non-CA
Independently PUCCH format and PUCCH resource are determined in the same manner, so simply and BS and UE can be clearly dictated
Operation.
Figure 46 is the overall flow figure for illustrating the various embodiments proposed in the present invention.In the example of Figure 46, logical
It crosses under the premise of higher level configures PUCCH format 3 for UE and provides explanation.
In step S4610, UE determines whether only to receive the PDSCH with DAI=1 on PCell (that is, corresponding to
The PDSCH of PDCCH with DAI=1).
If the result of step S4610 be it is yes, then follow the steps S4620.Because having DAI=1's on PCell
The TPC field of PDCCH is used for original TPC command, so UE cannot obtain ARI when only receiving the PDCCH with DAI=1
Information.Therefore, UE does not use PUCCH format 3.PUCCH format 1a/1b can be used to emit ACK/NACK in UE.It can lead to
Implicit mapping (that is, indexing by the extractive PUCCH resource of CCE rope from PDCCH) is crossed to determine PUCCH format 1a/1b's
Resource.
Meanwhile if the result of step S4610 be it is no, then follow the steps S4630.In step S4630, UE determination is
The no single PDSCH that the not PDCCH only on PCell has been received.
If the result of step S4630 be it is yes, then follow the steps S4640.Because UE receives PDCCH not yet,
UE cannot obtain ARI information, and not use PUCCH format 3.PUCCH format 1a/1b can be used to emit ACK/ in UE
NACK.Here, UE cannot be obtained from the extractive PUCCH resource of PDCCH CCE rope because receiving PDCCH not yet
Index.Therefore, UE can be according to the information for including in SPS activation PDCCH (for example, by activating the TPC in PDCCH in SPS
Field reuses indicated information) determine that PUCCH resource indexes.
If the result of step S4630 be it is no, then follow the steps S4650.In step S4650, UE determines whether
Receive ' PDSCH ' and other ' the not PDSCH ' of PDCCH with DAI=1 only on PCell.
If the result of step S4650 be it is yes, then follow the steps S4660.Even if in this case, because cannot obtain
ARI information, so UE replaces PUCCH format 3 using PUCCH format 1a/1b.Here, UE can pass through channel selection profile
Emit ACK/NACK information, to prevent the loss of ACK/NACK information.Channel selection can be executed, so that from A (=2
Or 3) a PUCCH resource selects PUCCH resource.Here, can determine A according to the quantity of the code word (or transmission block) of PDSCH
Value.
Meanwhile if the result of step S4650 be it is no, then follow the steps S4670.In step S4670, UE can be true
Fixed wherein DAI value is not whether the value of the ARI (that is, TPC field) of the PDCCH of 1 (that is, DAI > 1) is equal in one or more
ARI (that is, TPC field) value of all PDCCH on SCell.
If the result of step S4670 be it is yes, then follow the steps S4680.In this case, UE can be used is referred to by ARI
3 resource of PUCCH format shown emits ACK/NACK information.UE assumes that ARI value is identical in all PDCCH, and can be with
Step S4680 is executed using the ARI value at least one PDCCH.
Meanwhile if the result of step S4670 is no (that is, if ARI value on PCell and one or more SCell
It is unequal), then UE can abandon the received PDCCH of institute.
In short, ' PDSCH ', ' not PDCCH with PDCCH of ACK/NACK should be emitted it for UE
PDSCH (SPS-PDSCH) ' and ' SPS discharge PDCCH ', following UE behavior can be defined.However, the scope of the present invention is unlimited
In this, and can the available combinations of various embodiments through the invention execute TDD HARQ ACK/NACK resource allocation
It is operated with transmitting.
Firstly, the operation of non-CA system can be identical as ' the only PCell is received ' operation in CA environment.That is, when for
TDD HARQ ACK/NACK resource allocation and transmitting operation when UE configures a serving cell can configured with working as more than one
Only the TDD HARQ ACK/NACK resource when receiving PDSCH and/or PDCCH on PCell is divided in the case where a serving cell
Match and emit operation it is identical.It therefore, can be by the description of the operation on PCell hereinafter, when configuring only one serving cell
Replace with operation on the serving cell.
If the DAI in PDCCH of the PCell corresponding to PDSCH is 1, TPC field for original power control mesh
's.If the DAI in the PDCCH corresponding to PDSCH, which is greater than 1, TPC field, is used as ARI.Corresponding on SCell
TPC field in the PDCCH of all PDSCH is used as ARI.UE assumes that all ARI values are identical.
If UE only receives only one SPS-PDSCH on PCell, UE return back to PUCCH format 1a/1b.
If UE only receives the PDSCH (that is, PDSCH corresponding with PDCCH, with DAI=1) with DAI=1,
Then UE return back to PUCCH format 1a/1b.
If only receiving PDSCH and SPS-PDSCH with DAI=1 on PCell, by using
The channel selection profile of PUCCH format 1b emits to execute ACK/NACK.The quantity A of PUCCH resource for channel selection is
2 or 3.
If receiving one or more PDSCH (PDCCH corresponding with PDSCH, with DAI > 1) with DAI > 1,
It then uses by 3 resource of PUCCH format of ARI instruction and executes ACK/NACK transmitting.
If receiving one or more PDSCH on SCell, use by ARI instruction 3 resource of PUCCH format Lai
Execute ACK/NACK transmitting.
Therefore, for only receiving in PCell or on PCell and one or more SCell and ' having PDCCH's
PDSCH ', ' not the PDSCH (SPS-PDSCH) ' of PDCCH and ' SPS discharge all situations of one of PDCCH ', can not damage
Correctly and effectively emit ACK/NACK information in the case where losing ACK/NACK information.
Embodiment 15
Embodiment 15 is related to the resource allocation methods for PUCCH format 3.One serving cell of configuration will be described first
The case where and the case where configuring more than one serving cell, will be described later.
If being configured with a serving cell, PUCCH format 3 can be used, the channel selection of M=2 can be used,
Or PUCCH format 1a/1b can be used.
When using PUCCH format 3, if there are SPS PDSCH, UE can be assumed with DL in bundled window
The TPC field of DAI=1 is also used for ARI purposes.Then, UE can determine 3 resource of PUCCH format and can be used
PUCCH format 3 emits ACK/NACK.
In the case where wherein using the channel selection of M=2, operations described below can be executed.
If UE receives SPS PDSCH and PDCCH only with DL DAI=1 and has DL DAI without receiving band
> 1 PDCCH, then UE can be used M=2 channel selection and simultaneously for the PDSCH indicated by SPS PDSCH and have DL
The application space ACK/NACK of the PDCCH of DAI=1 bundlees to emit ACK/NACK.In order to emit 2 bit ACKs/NACK, UE
Can be used LTE version 8 implicit resource distribution (for example, table 5) rule or meet LTE version 10 mapping relations (for example,
Table 8).
It is assumed that UE by emitting ACK/NACK according to the channel selection profile of the mapping relations of LTE version 8, exists
SPS PDSCH and there is the case where PDCCH of DAI=1 and the case where there is only SPS PDSCH between, or there are SPS
The case where PDSCH and PDCCH with DAI=1 and the case where there is only the PDCCH with DAI=1 between carry out difference can
It can be indefinite.
, to solve the problems, such as in this, it can pass through activation SPS PDSCH's using the resource allocation for channel selection
The TPC field of PDCCH determinesAnd it is determined by CCE index corresponding with PDSCHIn addition,
HARQ-ACK (0) can be mapped to the ACK/NACK/DTX response of the transmission to SPS PDSCH, and HARQ-ACK (1) can
To be mapped to the ACK/NACK/DTX response of the transmission to the PDSCH with corresponding PDCCH.Then, when UE loss has
To SPS PDSCH's (selected channel and the in the channel bit or constellation that emit) when the PDCCH of DAI=1
ACK/NACK response can receive PDCCH with DAI=1 and corresponding with the PDCCH with DAI=1 with as UE
The ACK/NACK response to SPS PDSCH when PDSCH in the ACK/NACK response to SPS PDSCH is identical.That is, BS energy
Enough by the detection of fixing response part (selected channel and the in the channel bit or constellation that emit) come correctly
It receives and the ACK/NACK of SPS PDSCH is responded, whether detect the PDCCH with DAI=1 but regardless of UE.
Next, when UE receives SPS PDSCH and the only PDCCH with DAI=1 and has DL DAI without receiving
When > 1 one or more PDCCH, PUCCH format 1a/1b transmitting ACK/NACK is can be used in UE.
In this case, the first PUCCH resource indexesIt can be from PDCCH's corresponding with PDSCH
It is exported in CCE index, or may be configured to provide using SPS PUCCH indicated by the TPC field as SPS activation PDCCH
Source.When use space orthogonal resource transmitting diversity (SORTD), by by offset applications in PDCCH corresponding with PDSCH
CCE index, can from " CCE index+1 " the second PUCCH resource of export indexOr it can be configured to
Use the second PUCCH resource of SPS PUCCH resource.
Meanwhile more than one serving cell can be configured, following two methods can be applied.
As first method, the resource allocation for FDD PUCCH format 3 can be reused.In this case,
One or more TPC fields of one or more PDCCH on PCell can be used for original TPC purpose, and one
Or one or more TPC fields on one or more PDCCH on multiple SCell can be used for ARI purpose.If UE
SPS PDSCH or PDCCH are only received on PCell, then the binding of the ACK/NACK defined in LTE version 8 can be used.
As second method, the resource allocation for TDD PUCCH format 3 in non-CA can be reused.That is, working as
In the absence of SPS PDSCH, only the TPC field of the PDCCH with DAI=1 on PCell can be used for original TPC
Purpose, and the TPC field of all other PDCCH on PCell and SCell can be used for ARI purpose.On the other hand,
If SPS PDSCH exists, all TPC fields on PCell and one or more SCell can also be used for AIR mesh
's.UE can be assumed all AIR value having the same.When UE only receives SPS PDSCH on PCell or has DL
When the PDCCH of DAI=1, the PUCCH format 1a/1b defined in LTE version 8 can be used.When UE is only received on PCell
When to SPS PDSCH and with the PDCCH of DL DAI=1, one or more PUCCH defined in LTE version 8 is used
The channel selecting method of format 1a/1b can be used.
The transmission method of the UCI of two kinds or more of types
In previously described embodiments of the present invention 1 to 15, about for UE configure PUCCH format 3 in the state of with
" with corresponding PDCCH PDSCH ", " PDSCH (SPS PDSCH) without corresponding PDCCH " and CA, non-CA,
And only " DL SPS discharges PDCCH " in PCell reception condition describes the various examples of ACK/NACK transmission.
The UCI of UE transmitting includes ACK/NACK, SR, CSI etc..CSI may include RI, PMI (the first PMI and second
PMI), CQI etc..In some cases, it is desirable to emit ACK/NACK information together with other UIC (SR or SCI), that is,
In identical subframe.Here, the case where description wherein emits ACK/NACK, SR and CSI by PUCCH.That is, of the invention
Range be not applied to wherein ACK/NACK, SR and the CSI to be incidentally launched on PUSCH the case where.
Hereinafter, it will description is in the state of for configuration PUCCH format 3 UE when emitting SR together with ACK/NACK
Or emit example of the invention when CSI together with ACK/NACK.In other words, it will be described below using suitable
The method that PUCCH format emits ACK/NACK and SR or ACK/NACK and CSI (that is, the CSI in period) simultaneously.
Embodiment 16
Embodiment 16 is related to the transmission side when two ACK/NACK responses should be launched and at the same time SR is needed to transmit
Method.
In this case, two ACK/NACK response can be response to SPSP PDSCH and to one
The response of " PDSCH with corresponding PDCCH ".Alternatively, two ACK/NACK responses can be the sound to a SPS PDSCH
It should be with the response to one " DL SPS discharges PDCCH ".In two responses, for example, " PDSCH with corresponding PDCCH "
In or the DL DAI value of PDCCH in " DL SPS discharge PDCCH " can be 1.In addition, an ACK/ in the present invention
NACK response can correspond to single ACK/NACK response group, also, therefore, and two ACK/NACK responses can indicate two
ACK/NACK response.
When needing while two ACK/NACK responses of transmitting are with SR, the present invention proposes to use PUCCH lattice by SR resource
The ACK/NACK of the ACK/NACK response (or an ACK/NACK response group) of formula 1b and another binding response (or
Person another binding ACK/NACK response group) transmission.
In two ACK/NACK responses, it can be first carried out and transmit related sky with the DL of two code words (2 CW)
Between bundle.For example, if one in two ACK/NACK response with a code word (1 CW) in relation to and two in it is another
It is a related with 2 CW, then space binding only is executed for 2 CW.Because only being deposited in the SPS PDSCH in LTE version 8/9
In 1 CW, so space binding cannot be executed to SPS PDSCH, and and if only if " corresponding with the PDCCH with DAI=1
PDSCH " or " the DL SPS with DAI=1 discharges PDCCH " can execute space binding when being configured as 2 CW.Then,
Relative to 2,3 or 4 bits before space bundlees, ACK/NACK payload is reduced to 2 bits.In this way, when must
Therefore space binding can be executed when wanting, and, 2 bit ACKs/NACK can be emitted by PUCCH format 1b (or 1a) and rung
It answers.
At this moment, the PUCCH lattice that the first PUCCH resource for PUCCH format 1b (1a) can be used as SR transmission distribution
The resource of formula 1.As necessary (using SORTD), the second PUCCH resource for PUCCH format 1b (1a) can
To use the Secondary resource of the PUCCH format 1 for RS transmission distribution.Such PUCCH format and resource allocation can indicate phase
The two ACK/NACK response answered return back to PUCCH format 1a and is re-used by phase rotation, that is, two ACK/
One in NACK response is mapped to I channel and another is mapped to Q channel.Alternatively, such PUCCH format and money
Source distribution can indicate that two ACK/NACK responses return back to PUCCH format 1b.
In other words, SR can be executed by using SR resource transmitting ACK/NACK information, and by SR resource
Constellation mapping can emit for the ACK/NACK of " SPS PDSCH " and for " PDSCH corresponding with PDCCH " or " DL
The ACK/NACK of SPS release PDCCH ".
For example, MSB can in 2 bit ACKs used in the PUCCH format 1b defined in LTE version 8/NACK response
Be mapped to be used for " SPS PDSCH " ACK/NACK and LSB can be mapped to for " with DAI=1's
The corresponding PDSCH " of PDCCH is used for the ACK/NACK with " the DL SPS of DAI=1 discharges PDCCH ".Alternatively, can be with
Corresponding ACK/NACK response is mapped to MSB and LSB by the opposite mode of above-mentioned example.Quilt can be emitted by SR resource
2 bit ACKs/nack message of mapping.
As another example, in QPSK constellation, the ACK/NACK for " SPS PDSCH " can be mapped to I axis,
And " PDSCH corresponding with the PDCCH with DAI=1 " or for " the DL SPS with DAI=1 discharges PDCCH "
ACK/NACK can be mapped to Q axis.Alternatively, corresponding ACK/NACK can be responded in above-mentioned exemplary opposite mode
It is mapped to I axis and Q axis.In addition, in the ACK/NACK for " SPS PDSCH " and for " with PDCCH pairs with DAI=1
In the ACK/NACK of the PDSCH " or " the SPS release PDCCH with DAI=1 " that answer, according to time sequencing for receiving first
To the ACK/NACK of channel can be mapped to the ACK/NACK of I axis and the channel for receiving later and can be mapped
To Q axis.Alternatively, corresponding ACK/NACK response can be mapped to I axis and Q axis in above-mentioned exemplary opposite mode.It can be with
Emit the 2 bit ACKs/nack message being mapped by SR resource.
As another example, in QPSK constellation, ' 1,1 ' and ' 0,0 ' can be mapped to for " SPS PDSCH "
ACK/NACK, and ' 0,1 ' and ' 1,0 ' can be mapped to " PDSCH corresponding with the PDCCH with DAI=1 " or " tool
There is the DL SPS release PDCCH " of DAI=1.Alternatively, can be corresponding ACK/NACK to be rung with the opposite mode of above-mentioned example
I axis and Q axis should be mapped to.2 bit ACKs/the nack message being mapped can be emitted by SR resource.
It can be in an identical manner using such as the ACK/ for the DL transmission in QPSK constellation in the examples described above
The mapping of NACK, no matter whether the transmission mode (TM) of each cell is MIMO or whether space binding is actually applied.
It is minimized according to the binding of above-mentioned example, the ACK/NACK information emitted by SR resource, and to SPS
The ACK/NACK response of PDDSCH can steadily be emitted.
In the examples described above, although assuming to emit two ACK/NACK responses, two ACK/ for ease of description
The transmission method of NACK response can be extended and be applied to the transmission of more than two ACK/NACK response.That is, being more than two
The response of a ACK/NACK can be designated as two virtual ACK/NACK response groups and can be by such as in above-mentioned example
In QPSK constellation mapping be launched.For example, for " SPS PDSCH " ACK/NACK information can be mapped to I axis and
Other ACK/NACK information are (that is, for " PDSCH corresponding with PDCCH " and/or the ACK/ of " DL SPS discharges PDCCH "
NACK information) 1 bit ACK/nack message can be generated as by space binding and time domain binding and can be mapped to
Q axis.2 bit ACKs/the nack message being mapped can be emitted by SR resource.According to this example, it is used for because can distinguish
The ACK/NACK information of SPS PDSCH and the ACK/NACK information for others DL transmission, so can be improved for SPS
The detection performance of the ACK/NACK of PDSCH.
Embodiment 16-1
When UE receives one " SPS PDSCH " in TDD and one " corresponding with the PDCCH with DAI=1
In the case where needing when PDSCH " or one " DL SPS discharges PDCCH " while emitting ACK/NACK and SR, SR can be passed through
Resource emits ACK/NACK counter using PUCCH format 1b.
The transmission of ACK/NACK counter is referred in no transmitting each ACK/NACK response (or ACK/ of binding
Nack message) in the case where generate the information of how many acknowledgement character response in all ACK/NACK responses and fed back.The number of acknowledgement character response
Mesh (ACK counter information) can be mapped to QPSK constellation and then be launched.
For example, " 00 " can indicate that there is no ACK, and " 01 " can be indicated there are an acknowledgement character response in QPSK constellation,
" 10 " can indicate that there are two acknowledgement character responses, and " 11 " can indicate that there are three acknowledgement character responses.Then, relative to 2 to 4
Bit, ACK/NACK transport payload are reduced to 2 bits.2 bits can be emitted by PUCCH format 1b (/ 1a)
ACK/NACK information.
In this case, for PUCCH format 1b (/ 1a) the first PUCCH resource can be used for SR transmission and
The resource of the PUCCH format 1 of distribution.As necessary (using SORTD), for PUCCH format 1b (/ 1a) the
The Secondary resource for the PUCCH format 1 distributed for RS transmission can be used in two PUCCH resources.Such PUCCH format and money
Source distribution can indicate to indicate that the corresponding bit of ACK/NACK counter return back to PUCCH format 1a and passes through phase rotation
It is re-used, that is, one in the bit of instruction ACK/NACK counter information is mapped to I channel and another is mapped
To Q channel.Alternatively, such PUCCH format and resource allocation can indicate that two bits return back to PUCCH format 1b.That is, can
Execute SR to emit ACK/NACK information by using SR resource, and can by the constellation mapping in SR resource come
Emit ACK/NACK counter information.
Although the transmission of two ACK/NACK response, this hair has been described for ease of description in the examples described above
Bright principle can be applied to the transmission of more than two ACK/NACK response.For example, for more than two ACK/NACK
Response, ACK/NACK counter information can be repeatedly mapped to two bits.For example, in QPSK constellation, " 00 " can be with
Instruction be not present ACK, " 01 " can indicate there are one perhaps four acknowledgement character responses " 10 " can indicate that there are 2 or 5 ACK
Response, and " 11 " can indicate that there are 3 or 6 acknowledgement character responses.
Embodiment 17
In traditional 8 system of LTE version, PUCCH format 2/2a/2b is defined as emitting CSI (CQI/PMI/RI).For
Emit ACK/NACK and CSI simultaneously, can be used PUCCH format 2a/2b.Specifically, can by by modulated applications in
The RS symbol of PUCCH format 2a/2b emits ACK/NACK information.
For example, as shown in the following table 19, by about 1 bit (b (20)) or 2- bit (b (20), b (21)) ACK/
Nack message, which executes modulation, can be generated a modulation symbol (d (10)).
[table 19]
The modulation symbol (d (10)) being generated can be re-used during the generation of the RS sequence of PUCCH, and then make
It is launched with PUCCH format 2a/2b.For details related with PUCCH format 2a/2b, 3GPP TS 36.211 can be referred to
Chapters and sections 5.4.2.
In embodiment 17, describe in detail in the case of should emit two ACK/NACK response while emitting
The method of ACK/NACK and CSI (that is, in identical subframe).It is assumed that while configuring ACK/NACK and CSI by higher level
It transmits (that is, ACK/NACK and CSI simultaneous transmission parameter is arranged to TRUE)." ACK/NACK and CSI simultaneous transmission parameter quilt
The meaning for being set as TRUE " is sent out simultaneously in the case where no discarding CSI when ACK/NACK is transmitted with CSI transmission collision
Penetrate ACK/NACK and CSI.
Two ACK/NACK responses can be the response to one " SPS PDSCH " and " have corresponding PDCCH to one
PDSCH " response.Alternatively, two ACK/NACK response can be response to one " SPS PDSCH " and to " a DL
The response of SPS release PDCCH ".In these channels, " PDSCH with corresponding PDCCH " or " DL SPS release
The DL DAI value that PDCCH in PDCCH " can have as 1.In the present invention, an ACK/NACK response can correspond to one
A ACK/NACK response group.That is, two ACK/NACK responses also refer to two ACK/NACK response groups.
The invention proposes when needing that two ACK/NACK of transmitting response is with CSI simultaneously, by PUCCH format 2a (/
2b) (or an ACK/NACK response group) is responded using an ACK/NACK such as the RS modulation symbol shown in table 19
With the transmission of the ACK/NACK bundled a response (or ACK/NACK response group of a binding).
In two ACK/NACK responses, it can be first carried out about the ACK/NACK response transmitted to 2-CW DL
Space binding.For example, one in two ACK/NACK response be about 1 CW and the other is about 2 CW, can be only
Space binding is executed about 2 CW.In LTE version 8/9, because being not required in SPS PDSCH there is only 1 CW
Space binding is executed to SPS PDSCH and and if only if " PDSCH corresponding with the PDCCH with DAI=1 " or " is had
The DL PSS release PDCCH " of DAI=1 can execute space binding when being made of 2 CW.Then, it is bundled relative in space
2,3 or 4 bits before, ACK/NACK payload are reduced to 2 bits.Therefore, can pass through as necessary
PUCCH format 2b (/ 2a) emits 2 bit ACKs/NACK response.
Such PUCCH format and resource allocation can indicate to be multiplexed by phase rotation using PUCCH format 2a corresponding
Two ACK/NACK response, that is, one in two ACK/NACK response is mapped to I channel and another is mapped
To Q channel.Alternatively, such PUCCH format and resource allocation can indicate that two ACK/NACK responses are multiplexed to PUCCH
Format 2b.
In other words, it can be emitted by the constellation mapping in the RS modulation symbol in PUCCH format 2b (/ 2a) and be used for " SPS
The ACK/NACK of PDSCH " and the ACK/NACK for being used for " PDSCH corresponding with PDCCH " or " DL SPS discharges PDCCH ".
For example, MSB, which can be mapped to, is used for " SPS in 2 bits in the RS modulation symbol d (10) in table 19
The ACK/NACK of PDSCH ", and LSB can be mapped to for " PDSCH corresponding with the PDCCH with DAI=1 " or
ACK/NACK for " the DL SPS with DAI=1 discharges PDCCH ".Alternatively, can be in above-mentioned exemplary opposite mode
Corresponding ACK/NACK response is mapped to MSB and LSB.In this way, 2 bit ACKs/nack message can be mapped to RS modulation symbol
Number and be launched by PUCCH format 2b (/ 2a).
As another example, in the QPSK constellation of the RS modulation symbol d (10) of table 19, for " SPS PDSCH "
ACK/NACK can be mapped to I axis and " PDSCH corresponding with the PDCCH with DAI=1 " or for " have DAI
The ACK/NACK of=1 DL SPS release PDCCH " can be mapped to Q axis.Alternatively, can be with above-mentioned exemplary opposite side
Corresponding ACK/NACK response is mapped to I axis and Q axis by formula.In addition, in the ACK/NACK for " SPS PDSCH " and being used for
In " PDSCH corresponding with the PDCCH with DAI=1 " or the ACK/NACK of " SPS with DAI=1 discharges PDCCH ",
I axis can be mapped to according to ACK/NACK of the time sequencing for the channel being firstly received and for receiving later
The ACK/NACK of channel can be mapped to Q axis.Alternatively, can be in above-mentioned exemplary opposite mode by corresponding ACK/
NACK response is mapped to I axis and Q axis.Therefore, 2 bit ACKs/nack message can be mapped to RS modulation symbol and pass through
PUCCH format 2b (/ 2a) is launched.
As another example, in the QPSK constellation in the RS modulation symbol d (10) of table 19, ' 1,1 ' and ' 0,0 ' can be by
Be mapped to the ACK/NACK for " SPS PDSCH ", and ' 0,1 ' and ' 1,0 ' can be mapped to " with DAI=1's
The corresponding PDSCH " of the PDCCH or ACK/NACK of " the DL SPS with DAI=1 discharges PDCCH ".Alternatively, can with it is upper
It states the opposite scheme of example and corresponding ACK/NACK response is mapped to I axis and Q axis.Therefore, 2 bit ACKs/nack message can
To be mapped to RS modulation symbol and be launched by PUCCH format 2b (/ 2a).
As the mapping of the ACK/NACK for the DL transmission in QPSK constellation in the examples described above can be with identical
Mode is applied, and whether TM but regardless of each cell is MIMO or whether space binding is actually applied.
It is minimized according to the binding of above-mentioned example, the ACK/NACK information emitted by CSI channel resource, and right
The ACK/NACK response of SPS PDDSCH can steadily be emitted.
In the examples described above, although assuming to emit two ACK/NACK responses, two ACK/ for ease of description
The transmission method of NACK response can be applied to the transmission of more than two ACK/NACK response.That is, more than two ACK/
The response of NACK can be designated as two virtual ACK/NACK response groups, and can be by as in the examples described above
QPSK constellation mapping is launched.For example, the ACK/NACK information for " SPS PDSCH " can be mapped to I axis and other
ACK/NACK information (that is, the ACK/NACK letter for " PDSCH corresponding with PDCCH " and/or " DL SPS discharge PDCCH "
Breath) 1 bit ACK/nack message can be generated as by space binding and time domain binding and Q axis can be mapped to.Cause
This, 2 bit ACKs/nack message can be mapped to RS modulation symbol and is launched by PUCCH format 2b (/ 2a).According to
This example is believed for the ACK/NACK information of SPS PDSCH with other ACK/NACK for DL transmission because can distinguish
Breath, so can be improved the detection performance of the ACK/NACK for SPS PDSCH.
Embodiment 17-1
When UE receives one " SPS PDSCH " in TDD and one " corresponding with the PDCCH with DAI=1
PDSCH " or when " DL SPS discharge PDCCH ", needs to emit ACK/NACK and CSI simultaneously.ACK/ is being configured by higher level
In the case where transmitting (ACK/NACK and CSI simultaneous transmission parameter=TRUE) while NACK and CSI, PUCCH lattice can be used
Formula 2b (/ 2a) emits ACK/NACK as being used for while emitting the method for ACK/NACK and CSI (that is, in identical subframe)
Counter.
The transmission of ACK/NACK counter refers to all in the case where each ACK/NACK of no transmitting is responded
The information (or tied ACK/NACK information) how many acknowledgement character response are generated in ACK/NACK response is fed back.Acknowledgement character response
Number (ACK counter information) can be mapped to such as the QPSK constellation of RS modulation symbol d (10) shown in table 19 and
Then it is launched.
For example, ' 00 ' can indicate that there is no ACK, and ' 01 ' can indicate there are an acknowledgement character response in QPSK constellation,
' 10 ' can indicate that there are two acknowledgement character responses, and ' 11 ' can indicate that there are three acknowledgement character responses.Then, relative to 2 to 4
Bit (2 or 3 bits), ACK/NACK transport payload is reduced to 2 bits.Can by PUCCH format 2b (/
2a) emit 2 bit ACKs/nack message.
Although the transmission of two ACK/NACK response, this hair has been described for ease of description in the examples described above
Bright principle can be applied to the transmission of more than two ACK/NACK response.For example, being used for more than two ACK/NACK
The ACK/NACK counter information of response can be repeatedly mapped to two bits.For example, ' 00 ' on QPSK constellation can be with
Instruction be not present ACK, ' 01 ' can indicate there are one perhaps four acknowledgement character responses ' 10 ' can indicate that there are 2 or 5 ACK
Response, and ' 11 ' can indicate that there are 3 or 6 acknowledgement character responses.

If there are at least one PDSCH on one or more SCell, PUCCH format 3 can be used for ACK/
NACK feedback.
If PDSCH transmission is not present on SCell, the resource and ACK/ of PUCCH format 1a/1b can be used
NACK mapping ruler.Specifically, if in the case of PDCCH corresponding with PDSCH is not present on SCell on PCell
There is no PDCCH and PDSCH, then because there is no DL transmission (that is, DTX), PUCCH format 1a/1b is not launched.
Meanwhile if there are PDSCH (SPS on PCell in the case of PDCCH corresponding with PDSCH is not present on SCell
PDSCH or PDSCH corresponding with PDCCH) or there is the PDCCH for indicating DL SPS release on PCell, then it can lead to
Cross PUCCH format 1a/1b transmitting ACK/NACK.
When it is assumed that above-mentioned ACK/NACK transmission operates, it should be sent out in the subframe for wherein configuring SR transmission by higher level
Operations described below can be executed in the case where penetrating ACK/NACK.
If there is at least one PDCCH, SR and ACK/NACK corresponding with PDSCH on PCell and SCell
Information is jointly encoded or is re-used and is launched by PUCCH format 3.
If PDCCH is not present on PCell in the case of PDCCH corresponding with PDSCH is not present on SCell
And PDSCH, then because there is no DL transmission (that is, DTX), PUCCH format 1a/1b is not launched.In such situation
Under, positive/negative SR is emitted by on-off keying (OOK) scheme.That is, the transmission about SR resource corresponds to positive SR and about SR
The non-transmitting of resource corresponds to negative SR.
If there are PDSCH on PCell in the case of PDCCH corresponding with PDSCH is not present on SCell
(SPS PDSCH or PDSCH corresponding with PDCCH) or the PDCCH that there is instruction DL SPS release on PCell, then
SR and ACK/NACK information can be emitted by emitting ACK/NACK information using PUCCH format 1a/1b in SR resource.
Specifically, in the case where positive SR, ACK/NACK information is emitted in SR PUCCH resource, and in the case where negative SR, it can

And the method for another UCI (SR or CSI).Specifically, the case where DAI field that the present embodiment is related to PDCCH is used as ARI.
First, it is assumed that PUCCH format 3 is substantially used for ACK/NACK feedback in the FDD system of CA configuration.It also assumes that
TPC field in the PDCCH for the PDSCH emitted on PCell is used for original TPC command, and is being used for
DAI field in the PDCCH of the PDSCH emitted on PCell is used for ARI purpose.Further, it is assumed that in one or more
The TPC field (or DAI field) of one or more PDCCH of the PDSCH emitted on SCell is used as ARI.
In further detail, in the PDCCH for dispatching PDSCH on the PCell or PDCCH of instruction SPS release,
TPC field in PDCCH can be used for TPC command and the DAI field of PDCCH is used as PUCCH format 3
ARI.TPC field for dispatching the PDCCH of the PDSCH on SCell is used as the ARI of PUCCH format 3.?
This, it is assumed that the ARI value of all PDCCH on PCell and SCell is identical.
If there are at least one PDSCH or on PCell, there are at least one PDSCH, PUCCH on SCell
Format 3 can be used for ACK/NACK feedback.
If PDSCH corresponding with PDCCH is not present on PCell and SCell, LTE version 8 can be used
The resource and ACK/NACK mapping ruler of PUCCH format 1a/1b.Specifically, if on PCell and SCell there is no with
SPS PDSCH is not present in the case of the corresponding PDCCH of PDSCH, then corresponds to the transmission of DTX and PUCCH format 1a/1b
It is not launched.
Meanwhile if in the case of PDSCH corresponding with PDCCH is not present on PCell and SCell on PCell
There are SPS PDSCH, then can emit ACK/NACK by PUCCH format 1a/1b.
The transmission of ACK/NACK and SR can be executed as follows.
If there is at least one PDCCH, SR and ACK/NACK corresponding with PDSCH on PCell and SCell
Information can be jointly encoded or be re-used and is launched by PUCCH format 3.
If PDSCH corresponding with PDCCH is not present on PCell and SCell and SPS PDSCH is also not present,
Then correspond to DTX and being transmitted without for PUCCH format 1a/1b is launched.In this case, it can be held by OOK scheme

Embodiment 20
In embodiment 20, description in the TDD system that CA is configured for emitting for the DL ACK/NACK transmitted and separately
The method of one UCI (SR or CSI).Specifically, the case where TPC field that the present embodiment is related to wherein PDCCH is used as ARI.
In this embodiment it is assumed that the DAI field and TPC field of PDCCH are defined as foloows.
DAI field on PCell is used as the counter of the PDCCH on PCell.DAI field on SCell can be by
As one in following proposal.First scheme is the PDCCH meter that the DAI field on SCell is used as on corresponding SCell
Number device.Another program is that the DAI field on SCell is arranged to ' 00 ' and even to dispatch DCI in public search space.
For UE implementation, predetermined value ' 00 ' is also used as virtual CRC.
Meanwhile TPC field (that is, PDCCH with DAI=' 00 ' or DAI=1) quilt distributed first on PCell
For original TPC purpose.Other all PDCCH are (all on the PDCCH and SCell with DAI > 1 on PCell
PDCCH) TPC field be used for ARI purpose.It is assumed that being transmitted on corresponding all PDCCH with a PUCCH
ARI value is identical.
If there are PDSCH transmission and PDCCH corresponding with PDSCH transmission is not present on PCell, UE is as follows
Ground operation.If there is no PDSCH transmission, then PUCCH format 1a/1b transmitting ACK/NACK can be used in UE.Meanwhile if
There are PDSCH transmission, then the transmitting of PUCCH format 3 ACK/NACK (exception, the PDCCH with DAI=' 00 ' can be used in UE
TPC field be used as ARI).
In other cases, if existing on PCell (has DAI=' 00 ' (or DAI=1) with PDCCH
PDCCH) a corresponding PDSCH or if on PCell exist instruction DL SPS release a PDCCH (have
The PDCCH of DAI=' 00 ' (or DAI=1)), then PUCCH format 1a/1b transmitting ACK/NACK can be used in UE.In other words,
PUCCH format 3 can be used and emit ACK/NACK.
In short, there are the PDSCH (SPS PDSCH) that one does not have corresponding PDCCH, only existing when on PCell
There are a PDSCH with corresponding PDCCH (PDCCH with DAI=' 00 ' (or DAI=1)) on PCell, or
The PDCCH that person only has instruction DL SPS release in the case where PDSCH is not present on SCell on PCell (has
The PDCCH of DAI=' 00 ' (or DAI=1)) when, PUCCH format 1a/1b can be used.In other cases, can make
With PUCCH format 3.Here, when, there is no when the PDSCH without corresponding PDCCH, there is DAI=' 00 ' on PCell
The TPC field quilt of the PDCCH (PDCCH corresponding with PDSCH or the PDCCH of instruction DL SPS release) of (either DAI=1)
TPC field for the order of TPC field and others PDCCH is used for ARI purpose.In other cases, all
The TPC field of PDCCH is used for ARI purpose.UE assume with a PUCCH transmit in corresponding all PDCCH by with
It is identical for making the value of the field of ARI.
If configuring SR transmission by higher level wherein in the state of executing ACK/NACK as described above transmission
It needs to emit positive SR and ACK/NACK in subframe, then can execute operations described below.
When there is a PDSCH without corresponding PDCCH on PCell, only existing and having on PCell
The corresponding PDSCH of the PDCCH of DAI=1 (perhaps DAI=' 00 ') only exists on PCell with DAI=1
A PDCCH of (or DAI=' 00 ') and instruction DL SPS release, and can be by using PUCCH in SR resource
Format 1a/1b emits ACK/NACK information to emit SR and ACK/NACK information.
For example, if be configured to in above-mentioned only PCell reception condition sent out in identical frame in a tdd system
Penetrate ACK/NACK information and SR, then UE can be used PUCCH format 1b by SR resource emit ACK/NACK counter.ACK/
NACK counter is the information of the number of the acknowledgement character response in the multiple ACK/NACK responses of instruction.For example, if ACK/NACK is counted
Number device is expressed as 2 bits (b (0), b (1)), then ' 00 ' indicates that ACK is not present, and ' 01 ' indicates that there are an ACK to ring
It answers, ' 10 ' indicate that there are two acknowledgement character responses, and ' 11 ' indicate that there are three acknowledgement character responses.Alternatively, if license counts ACK
Device information is repeatedly mapped to 2 bits (b (0), b (1)), then ' 00 ' can indicate that there is no ACK, ' 01 ' can indicate exist
One perhaps four acknowledgement character responses ' 10 ' can indicate there are 2 or 4 acknowledgement character responses, and ' 11 ' can indicate there are 3 or
6 acknowledgement character responses of person.On the other hand, negative SR is transmitted, UE emits ACK/NACK response by ACK/NACK PUCCH resource
(for example, ACK/NACK response of binding).
(that is, in addition to there is a PDSCH without corresponding PDCCH on PCell, only exist in other situations
On PCell there are one with there is the corresponding PDSCH of the PDCCH of DAI=1 (perhaps DAI=' 00 ') or only in PCell
The upper feelings existed except the case where there is DAI=1 (or DAI=' 00 ') and indicate a PDCCH of DL SPS release
Condition), SR and ACK/NACK are jointly encoded and are multiplexed and emitted using PUCCH format 3.
Next, transmission while ACK/NACK and CSI will be described.In this embodiment it is assumed that being matched by higher level
Transmission while setting ACK/NACK and CSI.
If there is a PDSCH without corresponding PDCCH on PCell, only exists and have on PCell
The corresponding PDSCH of the PDCCH of DAI=1 (perhaps DAI=' 00 ') only exists on PCell with DAI=1
(or DAI=' 00 ') and PDCCH for indicating DL SPS release, then it is multiple to can be used a series of PUCCH format 2
With with transmitting ACK/NACK information and CSI.Specifically, can be emitted by the RS modulation symbol of PUCCH format 2/2a/2b
ACK/NACK information.In addition, PUCCH format 2a/2b transmitting CSI and ACK/NACK can be used in the case where normal CP
Information, and in the case where the CP of extension, CSI and ACK/NACK that PUCCH format 2 emits combined coding can be used.
For example, if be configured to in above-mentioned only PCell reception condition sent out in identical frame in a tdd system
Penetrate ACK/NACK information and CSI (CQI/PMI/RI) and using a series of PUCCH format 2 execute ACK/NACK information and
It is transmitted while CSI, then ACK/NACK counter information can be emitted by the RS modulation symbol of PUCCH format 2/2a/2b.Example
Such as, it if ACK/NACK counter is expressed as 2 bits (b (0), b (1)), then ' 00 ' indicates that ACK is not present, ' 01 ' indicates
Indicate that there are two acknowledgement character responses there are one or four acknowledgement character responses, ' 10 ', and ' 11 ' indicate that there are three acknowledgement character responses.
Alternatively, then ' 00 ' can indicate not deposit if ACK counter information is repeatedly mapped to 2 bits (b (0), b (1)) by license
In ACK, ' 01 ' can indicate there are 1 perhaps 4 ACK response ' 10 ' can indicate that there are 2 or 5 acknowledgement character responses, and
' 11 ' can indicate that there are 3 or 6 acknowledgement character responses.In the case where normal CP, PUCCH format 2b and CSI can be used
Emit ACK/NACK counter information together, and in the case where the CP of extension, PUCCH format 2 and CSI mono- can be used
Play transmitting ACK/NACK counter information.
