Description

Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, apparatus, device, and storage medium for sending and receiving HARQ-ACK. Background Art

[0002] To ensure scheduling flexibility, one downlink control information (DCI) can schedule a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH).

[0003] When the sub-carrier space (SCS) is 960 kHz, the corresponding time slot length is 1 / 64 ms. When the sub-carrier space is large and the time slot length is small, if each PDSCH is scheduled with a separate DCI, the DCI blind detection overhead will be too high.

[0004] In the multi-TTI (Multi Transmission Time Interval, Multi-TTI) design, one DCI can schedule PDSCH / PUSCH of multiple time slots.

[0005] For example, in a multi-TTI PDSCH scheduling scenario, one DCI can schedule four PDSCHs, which correspond to four consecutive time slots. These four PDSCHs can be used to transmit different data, that is, different transport blocks (TBs). Using a multi-TTI design can reduce the number of DCIs, thereby reducing the complexity of UE blind DCI detection.

[0006] In a multi-TTI PDSCH scheduling scenario, the number of PDSCHs scheduled by a DCI may be semi-statically configured by a higher layer, or may be dynamically indicated by the scheduling DCI after a numerical range is indicated by a protocol or configured by higher layer signaling.

[0007] In a multi-TTI PDSCH scheduling scenario, HARQ-ACK of multiple PDSCHs needs to be fed back on the same PUCCH. Summary of the Invention

[0078] The embodiments of the present disclosure are now further described with reference to the accompanying drawings and specific implementation methods.

[0079] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0080] Type 1 codebook is a HARQ-ACK feedback method with a fixed HARQ-ACK codebook size. On a channel that feeds back HARQ-ACK, the HARQ-ACK of valid PDSCH candidate time-frequency resources on all time slots contained in a fixed-size feedback window is fed back.

[0081] Configuration information about the Type 1 HARQ-ACK codebook includes:

[0082] Configuration information 1: The first set (called K1 set) is configured by protocol agreement or through high-level signaling. This K1 set contains L integer elements, each integer element indicates the time slot interval between the PDSCH and the channel used to feedback the HARQ-ACK of the PDSCH. K1 set is {k1, k2, ..., k L}.

[0083] The default K1 set specified by the protocol is {1, 2, 3, 4, 5, 6, 7, 8}. The K1 set configured by the base station is a maximum of 8 values from 0 to 15, or in some protocols, the K1 set configured by the base station is a maximum of 8 values from -1 to 1 to 15.

[0084] Configuration information 2, the first interval value indicated in the DCI is a value in the K1 set. The first interval value is k i express.

[0085] Configuration information three: the PDSCH scheduled by DCI is in slot N (time slot with position identifier N).

[0086] According to the above configuration information, the user equipment will be in slot N+k i The HARQ-ACK of the PDSCH scheduled by the DCI is sent on the channel.

[0087] The feedback window corresponding to the Type 1 HARQ-ACK codebook that can be contained in the channel for feeding back the HARQ-ACK is a window consisting of the following slots:

[0088] {slot N+k i -k1, slot N+k i -k2,……,slot N+k i -k i-1 ,slot N,slot N+k i -k i+1 ,……,slot N+k i -k L}

[0089] The determination of this window can be understood as the channel slot N+k i Each integer value in the K1 set is reversed, and the time slots obtained after reverse calculation constitute the feedback window, that is, the slot N+k i The HARQ-ACK channel on the PDSCH needs to include the HARQ-ACK information of each PDSCH in this feedback window.

[0090] Among them, the PDSCH candidate time-frequency resource on a certain time slot in this feedback window is not scheduled, or there is actual PDSCH scheduling, but the DCI indicates that the HARQ-ACK of the PDSCH is not in slot N+k i When feedback is given, the feedback result corresponding to the PDSCH candidate time-frequency resource in this slot is NACK.

[0091] When a DCI schedules multiple TTI PDSCHs, when a Type 1 HARQ-ACK codebook is used, after the first interval value is indicated in the DCI, the Type 1 HARQ-ACK codebook determined according to the first interval value cannot include the HARQ-ACK information of all PDSCHs scheduled by the DCI.

[0092] For example:

[0093] A multi-TTI PDSCH scheduled by a DCI includes M PDSCHs in total, and the time slots corresponding to the M PDSCHs are: slot n, slot n+1, ..., slot n+M-1.

[0094] The configured K1 set contains L values, K1 set is {k1,k2,……,k L}.

[0095] The first interval value indicated in the DCI is a value in the K1 set.i express.

[0096] The user equipment will be in slot n+M-1+k i The HARQ-ACK of the PDSCH scheduled by the DCI is sent on the channel.

[0097] The feedback window corresponding to the Type 1 HARQ-ACK codebook that can be contained in the channel for feedback of the HARQ-ACK is a window consisting of the following slots:

[0098] {slot n+M-1+k i -k1,slot n+M-1+k i –k2,……,slot n+M-1+k i -k i-1 ,slot n+M-1,slot n+M-1+k i -k i+1 ,……,slot n+M-1+k i –k L}.

[0099] This window does not necessarily completely include the slot where each PDSCH in the multi-TTI PDSCH is located, that is, each slot in {slot n, slot n+1, ..., slot n+M-1}.

[0100] How to ensure that the Type 1 HARQ-ACK codebook included in the channel for feedback of HARQ-ACK includes the HARQ-ACK corresponding to the slot where each PDSCH in the multi-TTI PDSCH is located is a technical problem that needs to be solved.

[0101] It should be noted that the channel used to feedback HARQ-ACK described in the present disclosure can be a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH, which is not limited here.

[0102] The embodiment of the present disclosure provides a method for sending HARQ-ACK, which is applied to a user equipment. Figure 1 , Figure 1 FIG. 1 is a flow chart of a method for sending HARQ-ACK according to an exemplary embodiment. Figure 1 As shown, the method for sending HARQ-ACK includes:

[0103] Step S11: Determine a first time slot set and a second time slot set, wherein the first time slot set includes time slots corresponding to multiple TTI PDSCHs; the second time slot set includes time slots included in the feedback window corresponding to the HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in the PUCCH of the HARQ-ACK for feedback of the multi-TTI PDSCH.

[0104] Step S12, determining at least one time slot group included in the first time slot set and not included in the second time slot set, and determining a target time slot corresponding one-to-one to each time slot group; the time slot group includes at least one time slot, and the target time slot is a time slot included in both the first time slot set and the second time slot set.

[0105] Step S13: Determine a logical HARQ-ACK on the target time slot according to the HARQ-ACK on each time slot in each time slot group and the HARQ-ACK on the target time slot corresponding to the time slot group.

[0106] Step S14: Send the HARQ-ACK codebook, where the HARQ-ACK codebook includes a logical HARQ-ACK on the target time slot.

[0107] In one embodiment, the first time slot set in step S11 includes time slots corresponding to multi-TTI PDSCHs, which means that the first time slot set includes time slots corresponding to all PDSCHs in the multi-TTI PDSCHs.

[0108] In one embodiment, the first time slot set in step S11 includes time slots corresponding to the multi-TTI PDSCH, which means that the first time slot set includes the time slot corresponding to each PDSCH in the multi-TTI PDSCH.

[0109] In one embodiment, the HARQ-ACK codebook is a Type 1 HARQ-ACK codebook.

[0110] In one embodiment, the time slots contained in each of the at least one time slot group are all continuous time slots, so that the distribution of the time slots in the divided time slot groups is relatively concentrated.

[0111] In an embodiment of the present disclosure, a first time slot set and a second time slot set are determined, at least one time slot group included in the first time slot set and not included in the second time slot set, and at least one target time slot included in both the first time slot set and the second time slot set are determined, the correspondence between the time slot group and the target time slot is determined, the HARQ-ACK of each time slot on the time slot group and the HARQ-ACK of the corresponding target time slot are logically bound to obtain a logical HARQ-ACK, and this logical HARQ-ACK is used as the final HARQ-ACK on the target time slot, so that the logical HARQ-ACK on the target time slot carries the HARQ-ACK of the corresponding time slot group, so that the HARQ-ACK code sent on the PUCCH indicated by the DCI can feedback the HARQ-ACK of all PDSCHs in the multi-TTI PDSCH.

[0112] The present disclosure provides a method for sending HARQ-ACK, which is applied to a user equipment. The method for sending HARQ-ACK includes:

[0113] Step 2.1: Determine a first time slot set and a second time slot set, wherein the first time slot set includes time slots corresponding to multiple TTI PDSCHs; the second time slot set includes time slots included in the feedback window corresponding to the HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in the PUCCH of the HARQ-ACK for feedback of the multi-TTI PDSCH.

[0114] Step 2.2, determine at least one time slot group included in the first time slot set and not included in the second time slot set, and determine a target time slot corresponding one-to-one to each time slot group; the time slot group includes at least one time slot, and the target time slot is a time slot included in both the first time slot set and the second time slot set.

[0115] Step 2.3: Perform a logical AND operation based on the HARQ-ACK on each time slot in each time slot group and the HARQ-ACK on the target time slot corresponding to the time slot group, and determine the result of the logical AND operation as the logical HARQ-ACK on the target time slot.

[0116] Step 2.4: Send the HARQ-ACK codebook, where the HARQ-ACK codebook includes a logical HARQ-ACK on the target time slot.

[0117] In one embodiment, the time slots contained in each of the at least one time slot group are all continuous time slots, so that the distribution of the time slots in the divided time slot groups is relatively concentrated.

[0118] When the sub-carrier spacing (SCS) is 480KHz or 960KHz, the duration of the corresponding time slot is very short. It can be considered that the channel conditions on multiple time slots change little, and the demodulation results of each PDSCH in the multi-TTI PDSCH are relatively consistent. Therefore, after bundling multiple HARQ-ACKs, the HARQ-ACK of each PDSCH in the multi-TTI PDSCH can still be more accurately reflected.

[0119] When determining the time slot of the PUCCH for feedback of HARQ-ACK, the time slot of the PUCCH for feedback of HARQ-ACK is determined according to the value of K1 indicated in the DCI and the time slot position of the last PDSCH in the multi-TTI PDSCH. Therefore, the last PDSCH in the multi-TTI PDSCH is generally included in the feedback window of the HARQ-ACK codebook. Therefore, when there is a time slot group included in the first time slot set and not included in the second time slot set, the HARQ-ACK of this time slot group can be logically combined with the HARQ-ACK of the time slot of the last PDSCH in the multi-TTI PDSCH to obtain a logical HARQ-ACK.

[0120] The present disclosure provides a method for sending HARQ-ACK, which is applied to a user equipment. The method for sending HARQ-ACK includes:

[0121] Step 3.1: Determine a first time slot set and a second time slot set, wherein the first time slot set includes time slots corresponding to multiple TTI PDSCHs; the second time slot set includes time slots included in the feedback window corresponding to the HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in the PUCCH of the HARQ-ACK for feedback of the multi-TTI PDSCH.

[0122] Step 3.2, determine all time slots included in the first time slot set and not included in the second time slot set as a time slot group, and determine a target time slot corresponding to the one time slot group; the target time slot is a time slot included in both the first time slot set and the second time slot set.

[0123] Step 3.3: Determine the logical HARQ-ACK on the target time slot based on the HARQ-ACK on each time slot in the time slot group and the HARQ-ACK on the target time slot corresponding to the time slot group.

[0124] Step 3.4: Send the HARQ-ACK codebook, where the HARQ-ACK codebook includes a logical HARQ-ACK on the target time slot.

[0125] In one embodiment, the time slots contained in each of the at least one time slot group are all continuous time slots, so that the distribution of the time slots in the divided time slot groups is relatively concentrated.

[0126] In an embodiment of the present disclosure, a first time slot set and a second time slot set are determined, all time slots included in the first time slot set and not included in the second time slot set are determined to be a time slot group, and a target time slot included in both the first time slot set and the second time slot set, the correspondence between the time slot group and the target time slot is determined, the HARQ-ACK of each time slot on the time slot group and the HARQ-ACK of the corresponding target time slot are logically bound to obtain a logical HARQ-ACK, and this logical HARQ-ACK is used as the final HARQ-ACK on the target time slot, so that the logical HARQ-ACK on the target time slot carries the HARQ-ACK of the corresponding time slot group, so that the HARQ-ACK code sent on the PUCCH indicated by the DCI can feedback the HARQ-ACK of all PDSCHs in the multi-TTI PDSCH.

[0127] The present disclosure provides a method for sending HARQ-ACK, which is applied to a user equipment. The method for sending HARQ-ACK includes:

[0128] Step 4.1: Determine a first time slot set and a second time slot set, wherein the first time slot set includes time slots corresponding to multiple TTI PDSCHs; the second time slot set includes time slots included in the feedback window corresponding to the HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in the PUCCH of the HARQ-ACK for feedback of the multi-TTI PDSCH.

[0129] Step 4.2, determine that all time slots included in the first time slot set and not included in the second time slot set are a time slot group, and determine a target time slot corresponding to the one time slot group; the target time slot is a time slot included in both the first time slot set and the second time slot set, and the target time slot is located after the last time slot in the one time slot group.

[0130] Step 4.3: Determine the logical HARQ-ACK on the target time slot based on the HARQ-ACK on each time slot in the time slot group and the HARQ-ACK on the target time slot corresponding to the time slot group.

[0131] Step 4.4: Send the HARQ-ACK codebook, where the HARQ-ACK codebook includes a logical HARQ-ACK on the target time slot.

[0132] In one embodiment, the time slots contained in each of the at least one time slot group are all continuous time slots, so that the distribution of the time slots in the divided time slot groups is relatively concentrated.

[0133] In one example:

[0134] The multi-TTI PDSCH scheduled by one DCI includes a total of 8 PDSCHs, and the slots where these 8 PDSCHs are located are slot n, slot n+1, slot n+2, slot n+3, slot n+4, slot n+5, slot n+6, and slot n+7.

[0135] The first set K1 set contains 4 consecutive integer elements, specifically {0, 1, 2, 3}.

[0136] It is determined that the first interval value T is the first value in the first set K1 set, that is, 0.
