Description
Technical field
The present invention relates to wireless communication systems, and more particularly, in long-term advancing time division duplex-frequency division duplex
The method and apparatus that control information is used for transmission in (LTE TDD-FDD) emerging system.
Background technology
In the last third generation partner program (3GPP) RAN#60 meetings, related LTE TDD-FDD are passed through
The work project of mixing operation, the purpose is to by include LTETDD-FDD carrier waves polymerize (CA) feature and potentially through according to
Other TDD-FDD mixing operations solutions of the initial stage scene assessment result of the Lai Yu work projects enhance LTETDD-FDD
Mixing operation.The carrier wave polymerization of FDD and TDD intercarriers can provide more systems to possess the operator of FDD and TDD frequency spectrums
Flexibility and performance benefit.But due to the difference between LTE FDD specifications and LTE TDD specifications, especially in control signaling and
Difference in terms of subframe sequential results in some problems in the polymerization of TDD-FDD carrier waves.
For example, as shown in Fig. 1 (a) in LTE FDD systems, transmitted for downlink (DL) and uplink (UL)
Two-way time (RTT) is fixed as 8ms, maximum hybrid automatic repeat-request (HARQ) number of processes (HPN) is fixed as 8, and
Under fdd mode, the position of positive acknowledgment (ACK)/negative confirmation (NACK) feedback is also fixed, i.e., the 3ms after DL transmission
It is transmitted after processing time.Therefore, in the fdd mode, 3 ratios are provided in DLDCI (down link control information)
Special HPN fields are sufficiently used for the HARQ number of processes of instruction DL transmission.
However, for tdd mode, the UL/DL due to UL transmission opportunities dependent on system is configured, thus be it is discontinuous,
Therefore user equipment (UE) can not can find UL subframe for the ACK/ to such as Physical Downlink Shared Channel (PDSCH)
NACK is fed back.UE needs to wait for until UL subframe arrival can just carry out ACK/NACK feedbacks.As shown in Fig. 1 (b), using
In the case of TDD UL/DL configurations 2, the position that the RRT times are 11ms and ACK/NACK is fed back is discontinuous.For example, in 3GPP
It is listed in table 7-1 in TS36.213 under the different configurations of TDD UL/DL, the maximum number of DL HARQ processes.1 weight of table
The content in table 7-1 is showed.
Table 1：The maximum number of DL HARQ processes for TDD
| TDD UL/DL configurations | The maximum number of HARQ processes |
| 0 | 4 |
| 1 | 7 |
| 2 | 10 |
| 3 | 9 |
| 4 | 12 |
| 5 | 15 |
| 6 | 6 |
It is configured according to TDD UL/DL, the interval between PDSCH transmission and ACK/NACK feedbacks is from 4 subframe lengths
It is differed to 13 subframe lengths, usually between 4ms to 13ms.Therefore, in tdd mode, the HPN fields in DL DCI are set
It is set to 4 bits.
Current 3GPP specifications set an important limitation for the HARQ transmission under state of carrier aggregation, i.e.,：It holds
The Physical Uplink Control Channel (PUCCH) for carrying HARQ is only capable of transmitting by principal component carrier wave (PCC).What is polymerize including carrier wave
It, will be by when TDD component carriers (CC) polymerize with FDD CC and TDD CC are configured as PCC in TDD-FDD emerging systems
TDD PCC loading ACKs/NACK is transmitted via PUCCH or PUSCH.At this point, for example shown in Fig. 2, for FDD DL CC,
After PDSCH being transmitted in one DL subframe by eNB, quilt in the UL subframe that the number in TDD PCC is 7 by ACK/NACK feedbacks
It sends, after then undergoing the processing delay of 3ms again, eNB just can send out PDSCH next again, and being used in this case should
The RTT of FDD DL CC is extended more than 8ms to 11ms, at this time if HPN fields are still set as 3 in FDD DL DCI
Bit long is then not enough to indicate actually required HPN.
In addition, the UE for being configured with more than one serving cell is defined in 3GPP TS36.213, in addition to
Except following situations, the ACK/NACK of all CC should be transmitted via PUCCH or via PUSCH on PCC：
If UE is configured with more than one serving cell and is not configured as being carried out at the same time PUSCH and PUCCH
Transmission, then in subframe n, if UCI is made of periodical CSI and/or HARQ-ACK and UE is not transmitted on main plot
PUSCH but transmit PUSCH at least one secondary cell, then uplink control information (UCI) should be with minimum
It is transmitted on the PUSCH of the secondary cell of ScellIndex (serving cell index).
Polymerize in situation in carrier wave, the above situation only in the case where PUCCH the and PUSCH resources of PCC are used up, because
, for particular UE, the probability happened is extremely low for this.For TDD-FDD CA, with minimum ScellIndex's
In the case that SCC is TDD CC, the RTT of the DL transmission on FDD CC still can exceed that 8ms.Therefore in such case
Under, the HPN of 3 bits is also not enough to the HPN of instruction actual needs.The scaling problem of HPN still has.
On the other hand, if the SCC with minimum ScellIndex is FDD CC, although FDD HARQ sequential can be deferred to
The ACK/NACK for FDD DL is transmitted, but for UE, according to whether there are PUCCH/PUSCH resources on TDD PCC
It distributes and switches between two kinds of HARQ sequential and acquire a certain degree of difficulty.

Specific implementation mode
Below with reference to each illustrative embodiments of attached drawing detailed description of the present invention.
It should be appreciated that providing these illustrative embodiments just for the sake of keeping those skilled in the art more preferable geographical
It solves and realizes the present invention in turn, be not intended to limit the scope of the invention in any way.
For the UL transmission under tdd mode, HPN fields are not present as a result of synchronous HARQ and in UL DCI,
Therefore there is no the HPN extensions caused by difference being previously mentioned in background technology due to HPN between FDD and tdd mode to ask
Topic.Therefore, each embodiment according to the present invention will relate to only the HPN scaling problems in DL transmission.
According to the present invention respectively embodiment there is provided a solution, pass through the modification to existing control signaling
To overcome the HPN scaling problems in the presence of the prior art above-mentioned.
According to one embodiment of present invention, by explicitly adding one into the HPN fields of existing FDD DL DCI
A additional bit and allow HPN fields to indicate up to 16 HARQ processes.If a UE is configured for TDD-FDD
CA, and TDD CC are configured as PCC, then need to modify to radio resource control (RRC) signaling for being currently used in CA
To notify the TDD-FDD CA configurations of the type.In this embodiment, once UE is scheduled, then eNB utilizes HPN pairs of 4 bits
Dispatch DL DCI (or DL licenses) coding of FDD DL CC resources；Then in the sides UE, UE will be based on the tool, and there are one added bits
New DCI sizes blind decoding is carried out to the DL DCI of the FDD CC.Which has been used to for dispatching across CC
In the decoding of the DCI of CIF (multi-carrier indicator field), details are not described herein.When UE recognizes the configuration of CA, in order to decode this
The DL DCI, UE of type will be used and executed blind decoding with the new DCI sizes for adding 3 bits.
The explicit signaling mode can be effectively to UE transmission and the associated HPN information of FDD CC, without increasing blind solution
The complexity of code.
According to another embodiment of the present invention, a kind of solution party transmitting HPN information to UE using implicit signaling is provided
Case.
In one example, HPN can be implicitly notified by the location information of the DL DCI in (e) PDCCH frames.Example
Such as, if DL DCI are located in the downlink subframe of odd-numbered, this just implicitly indicates to attached a ratio to HPN to UE
Spy 0；If DL DCI are located at the downlink subframe of even-numbered, this just implicitly indicates to attached a ratio to HPN to UE
Spy 1, vice versa.It will be appreciated by those skilled in the art that can be in such a way that other be different by DL DCI or including DL DCI
(e) PDCCH be arranged in different downlink subframes, as long as these modes can be used for implicitly to UE transmit and different DL CC
Associated HPN information, then can achieve the object of the present invention and fall under the scope of the present invention.
In another example, can by DL DCI or (e) PDCCH including DL DC I monitored in UE it is public
Position in search space or the exclusive search spaces UE implicitly to notify HPN to UE.For example, can be according to being applied
Control channel element (CCE) polymerization by DL DCI may residing for (e) PDCCH public search spaces or the exclusive search spaces UE
It is divided into two set, such as the first half of search space is divided into first set and is divided into the later half for searching plain space
Second set；Or it is divided according to odd/even index.Specifically, for example, if desired DCI is format 2, and CCE
Polymerization grade is 2, i.e. L=2, then the table 9.1.1-1 according to 3GPP TS36.213 can obtain searching UE is exclusive
The number of PDCCH candidates in rope space is M(L)=6.Table 2 has reproduced the content of table 9.1.1-1.
Table 2：The PDCCH of UE monitoring is candidate
Then, may further be divided to PDCCH can be divided into { 1,2,3 } simultaneously for two set, such as first set
And second set can be divided into { 4,5,6 }, implicitly notify that the added bit of HPN is 0 or 1 to user equipment with this,
Such as the DCI in the PDCCH of first set includes impliedly an added bit 0, and the DCI in the PDCCH of second set is hidden
Include an added bit 1 containing ground.However, it is understood by those of ordinary skill in the art that the division to set and and added bit
The correspondence of value is not limited to that any dividing mode that the object of the invention may be implemented and correspondence both fall within this hair
Within bright protection domain.
According to still another embodiment of the invention, a kind of side implicitly notifying the added bit on (e) PDCCH is provided
Formula.
In existing user equipment, user equipment can support 1 antenna port (Antenna Port), can also prop up
Hold mutiple antennas port, such as the double antenna port including antenna port 0 and antenna port 1.Support the user of multi-antenna port
User equipment emitting antenna selecting technology can be used to select antenna port to emit uplink signal in equipment.User equipment emits day
Line options are configured by high level.In current systems, if enabling closed loop antenna selection, i.e. base station, such as eNodeB passes through
Instruction should be permitted to indicate to answer in (DCI0) come the information coding for PUSCH using which antenna in uplink scheduling
When use, which antenna is used for PUSCH.For the UE with two emitting antennas, in base station side, base station is for example, by institute in table 3
One of two antenna selection masks listed scramble 16 CRC Parity Check Bits (for example, by mould 2 plus).Table 3
In listed antenna selection mask be to have reproduced the content of the table 5.3.3.2-1 in 3GPP TS36.212.
Table 3：UE emitting antenna selecting masks
Specifically, for being configured with the UE of two available transmission antennas, in base station side, after adding CRC, base station utilizes
One antenna selection mask and corresponding UE mark (for example, RNTI) masks carry out the CRC odd evens to the PDCCH with DCI format 0
Check bit is scrambled, and wherein UE mark masks are used to indicate the targeted UE of scheduling grant.In user equipment side, UE will make
Go to try to decode with two masks, that mask successfully decoded, then what UE can know base station be it is corresponding with " 1 " or with
" 0 " corresponding mask.This implicit coding avoids the use of explicit day line options bit, and explicit day line options may be led
The increased expense of the UE for emitting antenna selecting is not supported or is not configured in cause.
According to one embodiment of present invention, be based on reason same as emitting antenna selecting mask, using for example including
The HPN masks of two Bit Strings (such as two 16 Bit Strings shown in table 3) equally can be notified implicitly to UE will be attached to HPN
The value of the bit added.For example, in the sides eNB, UE can be identified ID and HPN mask by eNB, such as<0,0,0,0,0,
0,0,0,0,0,0,0,0,0,0,0>Applied to CRC.Then, in the sides UE, UE will utilize UE-ID and two HPN before CRC check
Mask, i.e.,<0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0>With<0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,1>Come
Decoding is executed, such as is operated into line position exclusive or (XOR) with data are received, in this example, is used<0,0,0,0,0,0,0,0,0,
0,0,0,0,0,0,0>Mask, which is decoded, obtains success, therefore UE can learn that the value of attached HPN bits is 0 right
Afterwards, in conjunction with the value of the HPN fields received, UE will be seen that the HPN information that base station is indicated to it.
Permit (PDCCH with DCI format 0) further, since UE antenna selection masks are only used for UL, and each reality of the present invention
It applies mode HPN scaling problems of interest and occurs only at DL licenses (i.e. with DCI format 1/1A/1B/1C/2/2A/2B/2D/3/
The PDCCH of 3A), therefore according to the embodiment of the present invention, UE antennas selection mask can be multiplexed for the HPN of 1 bit
Extension, to which the complexity of calculating and design will not be introduced.Table 4 shows HPN masks according to an embodiment of the invention
Example.
Table 4：HPN masks
The mode of this implicit notice HPN maintains the reliability of PDCCH and need not add new bit, therefore will not
Increase signaling overheads.
