Wireless communication system, such as the third generation (the third-generation, 3G) mobile phone standard and technology be
It is well-known.This 3G standard and technology are developed by third generation cooperative partner program.Third generation wireless communication is general
It has been developed and has supported macrocellular mobile phone communications.Communication system and network develop towards wide-band mobile systems.The third generation
Partner program has developed long term evolution (Long Term Evolution, LTE) system, the i.e. mobile electricity of evolved universal
Telecommunications System Terrestial Radio Access Network (Evolved Universal Mobile Telecommunication System
Territorial Radio Access Network, E-UTRAN), to be used for mobile access network；Wherein, macrocell is by claiming
It is supported by the base station of eNodeB or eNB (evolution node B).Recently, LTE just eats dishes without rice or wine towards so-called 5G or newly (New
Radio, NR) system further develops, and wherein cell is supported by the referred to as base station of gNB.
In the lte networks, using hybrid automatic repeat-request (Hybrid Automatic Repeat Request,
HARQ) mechanism, to correct the erroneous packet in PHY layer (transmission block).There are multiple HARQ processes so that sending device will pass
Defeated piece is sent to receiving device.Once transmission block is sent out from specific process, then the affirmative acknowledgement to be received such as general or negative are answered
Answer (ACK/NACK) bit (bit).Before sending device receives ACK/NACK, which will be in inactive state, and
And other transmission blocks will not be handled.Sending device buffers the transmission block of the transmission of multiple processes, so that the transmission
Equipment can be retransmitted in the case where receiving NACK, until receiving ACK.This is well-known with multiple
The stopping variable (stop-and-wait protocol) of concurrent process.It, can be to one in an ACK/NACK transmission
Multiple transmission blocks of a cell or multiple cells carry out ACK/NACK.HARQ-ACK/NACK information including multiple bits is usual
It is associated with HARQ-ACK/NACK code book.
In known downlink HARQ process in LTE, down link data passes through physical down link sharing channel
(Physical Downlink Shared Channel, PDSCH) is sent to wireless telecom equipment (or user from base station (eNB)
Equipment (User Equipment, UE)).Then, ACK/NACK information passes through physical uplink control channel (Physical
Uplink Control Channel, PUCCH) or physical uplink shared channel (Physical Uplink Shared
Channel, PUSCH) from UE it is sent to eNB.After NACK, if necessary to retransmit data, then data by PDSCH from
ENB resends to UE.In LTE, HARQ ACK/NACK is by uplink control information (uplink control
Information, UCI) carrying.ACK/NACK payload can be the consumption (drain) of available resources.Therefore, reduce
ACK/NACK payload/codebook size (and effectively reducing UCI payload), especially in uplink (from UE to
ENB ACK/NACK payload/codebook size), any means without damageeing HARQ process will be beneficial.
The known way for reducing ACK/NACK payload depends on (in binary system AND operation) by several ACK/NACK
Bit bundles.Wherein, each bit corresponds to downlink code word (wherein, code word is encoded transmission block), and
(individual bit is sent from UE to eNB).It can be bundled in multiple dimensions.For example, can be supported in available transmission mode
" space binding " is completed by transmitter in the case where each multiple code words of subframe.For transmitter, " time bundle can be completed
Tie up " to multiple subframes together ACK/NACK." cell binding " (or frequency binding) can be completed between each transmission time
It will be bundled across the ACK/NACK bit of the synchronized cells (across) every (Transmission Time Interval, TTI).

Specific embodiment
Those skilled in the art will recognize and appreciate that described exemplary details is only the explanation of some embodiments, and
And the introduction that the application is illustrated is arranged suitable for various substitutions.
Fig. 1 shows wireless communication system 100.Wherein, which can be LTE system or such as 5G/
Some other systems of NR system.System 100 supports HARQ process.System 100 may include multiple evolution node Bs (eNB) or
GNb 101 and other network entity (not shown).ENB or gNB and user equipment (User Equipment, UE) 102 is communicated,
And support respective (respective) cell 103.(in addition to this) every eNB/gNB also executes the function of base station.In general, every
One eNB/gNB can support multiple cells.ENB/gNB 101 has processing unit, and the function of the processing unit is then below
Middle explanation.UE 102 can be dispersed in whole system 100, and every UE can be static or movement at any one moment
's.UE 102 can be, such as cellular phone, smart phone, radio modem, laptop or other channel radios
Believe equipment.UE 102 is equipped with processing equipment 105；The function of the processing equipment 105 will be described hereinafter.System 100 is supported
Uplink (from UE 102 to eNB or gNB 101) and downlink (the HARQ process from eNB or gNB 101 to UE 102).
Uplink signal or channel may include the data about the PUSCH control information on PUCCH.Particularly, it in LTE, holds
The PUCCH for carrying UCI may include channel state information (channel state information, CSI) report, HARQ affirmative
Answering/no answering (ACKnowledgement/NegativeAcknowledgement, ACK/NACK) and uplink
Scheduling request (scheduling request, SR).UE 102 can be used PUCCH and provide HARQ-ACK feedback for PDSCH.It closes
In by the received down link data of PDSCH, ACK/NACK is fed back to eNB 101 by PUCCH by UE.In LTE system
Common, PUCCH can support the multiple format with various modulation and encoding scheme.
Referring now to the flow chart description of Fig. 2 for bundling showing for ACK/NACK information in wireless communication system 100
Example property method.In the illustrative example of data transmission on the uplink, the processing unit at 201, in eNB/gNB 101
104 determine bind instructions, and eNB 101 is that UE 102 is pre-configured bind instructions.In this example, when establish or reconfigure with
When the connection of UE 102, bind instructions are sent to UE 102 to complete to be pre-configured by RRC signaling.At 202, eNB/gNB
101 pairs of one or more code words encode, and send code word for the reception of UE 102.At 203, the reception of UE 102 is come from
Multiple code words at least one downlink subframe of eNB/gNB 101.At 204, UE 102 is to received multiple code words
It is decoded, and determines the affirmative acknowledgement (ACK) or negative response (NACK) for being used for each code word according to the decoding result of code word.
At 205, processing equipment 105 in UE 102 using received bind instructions come bundle for multiple code words ACK and
Nack message, to generate the ACK/NACK payload of binding.At 206, UE 102 is then effective by the ACK/NACK of binding
Load and Binding information relevant to ACK/NACK payload are sent to eNB/gNB 101.At 207, use what is received
Binding information, eNB/gNB can determine the size of ACK/NACK code book, and then to including in ACK/NACK payload
ACK/NACK information is decoded.
In another example embodiment, if it is desired that with dynamical binding method of the invention, or if biography should be used
The semi-static binding method of system substitutes, then eNB 101 is transmitted using (downlink transmission) bit to UE 102.
For example, be arranged in logical zero position bit indicate dynamical binding, and the bit that logical one position is set then indicate it is semi-static or
Non-dynamic binding.In another example, (downlink transmission) three bits can be used to transmit to UE 102 in eNB 101
Notice allow using binding type.For example, these three bits can be used for distinguishing space binding, time binding and cell (frequency
Rate) binding.
In one example, the traditional HARQ ACK/NACK code book of 105 pairs of the processing equipment in UE 102 is repaired as follows
Change.Before ACK/NACK response, additional (binding) information is added to traditional code book.The code book of modification is shown in Fig. 3
Example.First part 301 includes Binding information, and second part 302 includes the ACK/NACK response of binding and first part 301
Before first part 302.First part 301 includes first segment (section) 303, and first segment 303 includes about whether
Through the information for executing dynamical binding.Second segment 304 includes the information about tie-in mode, that is, the type of the binding executed,
Such as space/subframe binding, time binding, cell (frequency) binding.Third section 305 includes other information, for example, it is how many with
And which subframe is associated with the ACK/NACK of binding response or how many a or which component carrier and binding ACK/NACK
Response association.
According to permitted (in the bind instructions) content of eNB 101, UE 102 can check possible binding combination, and
Determine optimal binding combination.It is shown in Fig. 4 indicate the dynamical binding bit 303 shown in Fig. 3 in addition to, various possibility
Binding combination needed for additional payload.In these examples of Fig. 4, to the M subframe of N number of cell and each cell
(that is, bundled window of M subframe) reports ACK/NACK.Assuming that UE reports additional N-bit to indicate in which cell
Time binding is executed, and reports additional M-bit to indicate when that (that is, in which Time Transmission Interval) has used cell
Binding.
The decrement of ACK/NACK payload can be modified by various factors.For example, eNB can permit UE because of bundle
It ties up process and in payload includes a certain number of mistakes.ENB can also provide compression goal to UE, and be given at ACK/
The instruction of how many error bit can be sent in NACK code book.ENB can indicate that UE remains the UE Binding information sent
The bit (having used binding but not indicating mode for example, only confirming) of minimum number, to realize high-caliber compression.Alternatively,
ENB can request UE to send greater number of bit, for example to indicate tie-in mode, and send and subframe and component carrier phase
The information (for example, see " other information " in Fig. 3) of pass, to realize the compression of appropriate level.The particular value of given N and M and
Admissible to bundle wrong quantity, the processing equipment 105 in UE 102 is to the various combinations of tie-in mode (for example, only having time
Between bundle, room and time binding, space and cell binding, space, time and cell binding) ACK/NACK payload
Size is calculated, and selects the smallest tie-in mode of payload size, for reporting ACK/NACK to eNB.
In decoding, eNB102 must be known by the received exact size of ACK/NACK code book, to reconstruct ACK/
NACK bit 302 (referring to Fig. 3).In general, in LTE system, which can be mismatched with through-rate and channel decode into
Journey is realized.However, to achieve it, eNB and UE must have common reason to the ACK/NACK payload in UCI
Solution.A solution is that code book is divided into two parts.First part includes information related with the binding process that UE is used (figure
3 section 303,304 and 305).Second part includes the rest part (the 302 of Fig. 3) of payload.Then, eNB can sequence
Ground decoding payload.
In one example, the size of first part is fixed (configuration being arranged according to eNB).Due to first part
Relatively small (small number of bit) can be used robust (robust) coding method and comes to the first part by size
It is coded and decoded (for example, known standardization robust Reed-Miller (Reed-Muller) code in LTE).To first
After decomposing code, the size of second part will become known.That is, eNB is known exactly which when first part is decoded
How UE bundlees multiple A/N bits about multiple code words.For example, it is contemplated that two code words of each subframe, bundled window M=5
Subframe, the scene of N=5 cell.When not bundling, this will need the payload of 50 bits (that is, each subframe two in total
A bit is multiplied by five bits of each cell (M), multiplied by the quantity of cell (N).For example, eNB 101 is used by RRC
4 bits are pre-configured UE 102, so that: dynamical binding bit -1=1: can be used；Bit -2=1: space bundle can be used
It ties up；Bit -3=1: up time binding；And bit -4=1: cell binding can be used.At UE 102, to institute
When having all code words in the time bundled window (M=5) of N number of cell to be decoded, UE 102 prepares Binding information below:
Section 303=1 bit: dynamical binding has been used；Section 304=110: room and time is used only and bundlees；Section 305=11110: table
Show that each cell has only bundled 4 subframes.At eNB 101, when receiving Binding information (1-110-11110), eNB understands
And the payload of desired part 302 is made up of: each 1 bit of subframe is small multiplied by 5 multiplied by each 2 bit of cell
Area；10 bit in total.
In another example, the size of first part is variable.ENB must also sequentially solve section 303,304 and 305
Code.
In substitution solution, UE selects one in several fixing steps.Then, eNB carries out possible option
Blind decoding.For example, there may be several standardized possible compression level (examples if original payload is 100 bits
Such as, 10/20/30/40%).In that case, when enabling (enable) dynamical binding mode, eNB can be to such as 100/
The UCI payload of 90/80/70/60 bit carries out blind decoding.As cyclic redundancy check (Cyclic Redundancy
Check, CRC) success when, then find correct UCI.
Another solution uses the table of the 10.1.1-1 such as or in similar TS 36.213.Wherein, eNB is UE configuration
Maximal rate (and therefore maximum UCI payload), and UE attempts that the UCI of compression is made to be adapted to (fit) ratio and configured most
The size of the smaller possible payload of big code rate.UE is configured as UCI is made to be also adapted to all lesser payload big
It is small.
