Embodiment three
In order to become apparent from method provided by detailed description the embodiment of the present application, below in conjunction with specific example to this Shen
It method please be illustrated provided by embodiment, comprising:
If network side is allocated to the timing relationship between PDSCH to the HARQ-ACK of DCI format 1_1 by high-level signaling
The value collection of (i.e. downlink HARQ-ACK timing) is combined into K1={ 0,1,2,3,4,5,6,7 } (i.e. the second value set), i.e.,
Transmitted in slot n downlink transfer (PDSCH or indicating downlink SPS resource release PDCCH) can in slot n+K1 into
Row HARQ-ACK feedback, wherein for each downlink transfer, by the PDCCH using DCI format 1_1 for dispatching the downlink transfer

8。
Step 402, it for the HARQ-ACK transmitted on the same PUCCH or PUSCH in slot n+9, needs really
The number of fixed corresponding PDCCH monitoring occasion；
Wherein it is possible to gather for determining PDCCH monitoring occasion in the slot of slot n+9-K1 '-K0
Number；K0 is the timing relationship (i.e. scheduling timing) between the PDCCH to scheduled PDSCH of DCI format instruction,
K0 ∈ { scheduling timing set }；Alternatively,
PDCCH monitoring is determined in the slot set of slot n+9-0-K0 to slot n+9-8-K0
The number of occasion；
Such as assume that scheduling timing collection is combined into { 0,1,2,3 }, then need the slot n+8 in radio frames i-1
The number M of PDCCH monitoring occasion is determined within the scope of this to the slot n+6 of radio frames i；
As shown in figure 5, slot n+7 is unknown since slot n+9 and slot n+8 sheet is as uplink, these
All there is no PDCCH monitoring occasion in slot, it is assumed that there are PDCCH in each slot in DL slot
Monitoring occasion, it is thus determined that the collection of PDCCH monitoring occasion is combined into the slot of radio frames i-1
The slot n+6 of n+8 to radio frames i, i.e. M=9.
Step 403, the HARQ-ACK in slot n is determined according to the number (M) of PDCCH monitoring occasion

It can be dispatched down in the number of PDCCH monitoring occasion and each PDCCH monitoring occasion
The factor of the product of the number of row transmission as the corresponding HARQ-ACK codebook size of a carrier wave/cell/BWP, according to
The factor and a carrier wave/cell/BWP downlink transfer mode, determine a carrier wave/corresponding HARQ- of cell/BWP
The size of ACKcodebook, such as by one carrier wave of product of factor scale factor corresponding with each downlink transfer/small
The size of the corresponding HARQ-ACK codebook of area/BWP, wherein the corresponding scale factor of each downlink transfer is by downlink transfer
Mode and whether it is configured with the space HARQ-ACK and merges and determine, such as the corresponding scale factor C of each downlink transfer can determines
Justice are as follows: for being configured to 1TB or being configured to carrier wave/cell/BWP, C=1 of 2TB and the progress space HARQ-ACK merging, for
Carrier wave/cell/BWP, the C=2 for being configured to 2TB and merging without the space HARQ-ACK, for being configured with based on CBG transmission
Carrier wave, C=CBG maximum number；By the sum of corresponding HARQ-ACK codebook size of multiple carrier wave/cell/BWP, as end
Hold the HARQ-ACK codebook size in slot n+9；
Wherein, sequence of the HARQ-ACK of each downlink transfer in codebook includes: according to above-mentioned HARQ-ACK
The sequence of the downlink transfer received within the scope of the slot that timing and scheduling timing is determined is ranked up, a kind of
Mode is according to frequency domain after first time domain, i.e., one carrier wave/cell/BWP respectively determines respective PDCCH monitoring
The number of element in occasion set and set, first according to the corresponding PDCCH monitoring of carrier wave/cell/BWP
The number of element determines the carrier wave/cell/BWP HARQ-ACK codebook in occasion set and set, wherein
It can be according to sequence of each PDCCH monitoring occasion in PDCCH monitoring occasion set
The HARQ-ACK sequence of the downlink transfer on the carrier wave/cell/BWP is carried out, then by each carrier wave/cell/BWP HARQ-ACK
Codebook is concatenated together according to carrier wave/cell/BWP number order, can also time domain after first frequency domain, that is, be directed to all loads
Wave/cell/BWP determines the number of element in public a PDCCH monitoring occasion set and set, presses
According to sequence of each PDCCH monitoring occasion in PDCCH monitoring occasion set, each
In PDCCH monitoring occasion, HARQ-ACK codebook is generated according to carrier wave/cell/BWP number order, so
Afterwards in the corresponding HARQ-ACK of next PDCCH monitoring occasion that successively sorts.
Step 404, determining HARQ-ACK codebook is sent in slot n+9, can pass through PUCCH or PUSCH
It sends；
Step 405: base station side determines the HARQ-ACK transmitted in slot n+9 according to the method for same terminal side
The size of codebook receives the HARQ-ACK of terminal transmission according to the size of the determination on PUCCH or PUSCH channel
Codebook, and according to same terminal side to HARQ-ACK sort consistent mode parse to obtain each downlink transfer it is corresponding
HARQ-ACK；
It should be noted that the scheduling timing and HARQ-ACK timing in above-described embodiment is directed to based on slot's
Transmission and transmission based on mini-slot are all effective, and if it is the transmission based on slot, only one downlink is passed in each slot
It is defeated, if it is the transmission based on min-slot, there can be multiple downlink transfers in each slot.401~405 institute of above-mentioned steps
The method of offer can be independently operated, for each carrier wave/cell/BWP so that it is determined that the carrier wave/cell/BWP is corresponding
HARQ-ACK codebook, and then cascade and obtain the HARQ-ACK codebook that terminal is finally transmitted, it is also possible to for eventually
All carrier wave/cell/BWP of end polymerization are used in conjunction with, that is, determine one public PDCCH monitoring occasion
Number, for determining final HARQ-ACK codebook.It only include 1 PDCCH with each slot in above-described embodiment
For monitoring occasion, can to comprise more than 1 PDCCHmonitoring occasion in a slot,
In some slot and PDCCH can not be included to include PDCCH monitoring occasion in some slot
monitoring occasion.It is determined in above-mentioned steps 401~405 with being gathered according to PDCCH monitoring occasion
For HARQ-ACK codebook, if determining HARQ-ACK codebook according to downlink transfer set, process is similar, only needs
PDCCH monitoring will be determined according to scheduling timing and HARQ-ACK timing in the above process
The process of occasion set replaces with the process of determining downlink transfer set；Specifically, according to scheduling
