Description

[Technical Field]

[0001] The present disclosure relates to the field of wireless communication technology, and more particularly to a method, apparatus, device, and storage medium for transmitting and receiving HARQ-ACK. [Background technology]

[0002] To ensure scheduling flexibility, one Downlink Control Information (DCI) can schedule one Physical Downlink Shared channel (PDSCH) or one Physical Uplink Shared channel (PUSCH).

[0003] When the subcarrier spacing (SCS) is 960 kHz, the corresponding time slot duration is 1 / 64 ms. When the subcarrier spacing is large and the time slot duration is small, if each PDSCH uses one DCI scheduling scheme independently, the overhead of DCI blind detection will be high.

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

[0005] Take the following example of a multi-TTI PDSCH scheduling scenario: one DCI can schedule four PDSCHs, which correspond to four consecutive time slots in sequence. The four PDSCHs can be used to transmit different data, i.e., different transport blocks (TBs). Using a multi-TTI design reduces the number of DCIs, thereby reducing the complexity of UE blind detection of DCIs.

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

[0007] In a multi-TTI PDSCH scheduling scenario, it is necessary to feed back HARQ-ACKs of multiple PDSCHs in the same PUCCH. Summary of the Invention [Problem to be solved by the invention]

[0036] It should be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. [Brief explanation of the drawings]

[0040] Examples of the present disclosure will now be further described in conjunction with the drawings and specific embodiments.

[0041] Illustrative embodiments will now be described in detail, examples of which are illustrated in the drawings. The following description refers to the drawings, and unless otherwise indicated, like numerals in different drawings represent the same or similar elements. The embodiments described in the illustrative examples below do not represent all embodiments consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure, as detailed in the appended claims.

[0042] Type 1 codebook is a HARQ-ACK feedback method with a fixed HARQ-ACK codebook size, and in one feedback HARQ-ACK channel, HARQ-ACKs of valid PDSCH candidate time-frequency resources in all time slots included in one feedback window with a fixed size are fed back.

[0043] The configuration information regarding the Type 1 HARQ-ACK codebook includes the following configuration information 1 to 3.

[0044] In the configuration information 1, the first set (referred to as K1 set) is negotiated by a protocol or set by higher layer signaling. This K1 set includes L integer elements, and each integer element indicates the time slot interval between the PDSCH and the channel for feeding back the HARQ-ACK of the PDSCH. The K1 set is {k1, k2, ..., k L}.

[0045] The default K1 set defined by the protocol is {1,2,3,4,5,6,7,8}. The K1 set set by the base station is a maximum of eight numbers from 0 to 15, or in some protocols, the K1 set set by the base station is -1 and a maximum of eight numbers from 1 to 15.

[0046] The first interval value indicated in the configuration information 2, DCI, is one value in the K1 set. i It is expressed as:

[0047] Configuration information 3: The PDSCH scheduled by the DCI is in slot N (the time slot whose location identifier is N).

[0048] According to the above configuration information, the user equipment transmits the HARQ-ACK of the PDSCH scheduled by the DCI in slot N+k i Transmit on the channel at

[0049] The feedback window corresponding to the Type 1 HARQ-ACK codebook that may be included in the channel that feeds back the HARQ-ACK is a window configured by the following slots. {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}

[0050] The method for determining this window is slot N+k of the channel. i can be understood as backward reasoning each integer value in the K1 set forward, and each time slot obtained after backward reasoning constitutes the feedback window, i.e., the slot N+k i The HARQ-ACK channel in needs to include HARQ-ACK information for each PDSCH in this feedback window.

[0051] A PDSCH candidate time-frequency resource in a time slot within this feedback window is not scheduled, or there is actual PDSCH scheduling, but DCI indicates that the HARQ-ACK for that PDSCH is in slot N+k i If it indicates that no feedback has been given in this time slot, the feedback result corresponding to the PDSCH candidate time-frequency resource in this time slot is NACK.

[0052] When one DCI schedules a multi-TTI PDSCH, if a Type 1 HARQ-ACK codebook is used, after a first interval value is indicated in the DCI, the Type 1 HARQ-ACK codebook determined based on this first interval value cannot include HARQ-ACK information of all PDSCHs scheduled by the DCI.

[0053] For example, a multi-TTI PDSCH scheduled by one DCI includes a total of M PDSCHs, and the time slots corresponding to the M PDSCHs are sequentially slot n, slot n+1, ..., slot n+M-1.

[0054] The set K1 set contains L numbers, and the K1 set is {k1, k2, ……, k L}.

[0055] The first interval value indicated in the DCI is one value from the K1 set. i It is expressed as:

[0056] User equipment is slot n+M-1+k i In the channel in, the HARQ-ACK of the PDSCH scheduled by the DCI is transmitted.

[0057] The feedback window corresponding to the Type 1 HARQ-ACK codebook that may be included in the channel that feeds back the HARQ-ACK is a window configured by the following slots. {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}.

[0058] This window may not necessarily completely include the slots in which each PDSCH in the multi-TTI PDSCH is located, ie, each slot in {slot n, slot n+1, . . . , slot n+M-1}.

[0059] A technical problem to be solved is how to ensure that the Type 1 HARQ-ACK codebook that may be included in the channel for feeding back the HARQ-ACK includes the HARQ-ACK corresponding to the slot in which each PDSCH in the multi-TTI PDSCH is located.

[0060] It should be noted that the channel for feeding back the HARQ-ACK in the present disclosure may be a physical uplink control channel PUCCH or a physical uplink shared channel PUSCH, but is not limited thereto.

[0061] An embodiment of the present disclosure provides a method for transmitting HARQ-ACK applied to a user equipment. Referring to Figure 1, Figure 1 is a flowchart of a method for transmitting HARQ-ACK shown in an exemplary embodiment. As shown in Figure 1, the method for transmitting HARQ-ACK includes the following steps S11 to S14.

[0062] Step S11: determine a first time slot set and a second time slot set, where the first time slot set includes time slots corresponding to a multi-TTI PDSCH, the second time slot set includes time slots included in a feedback window corresponding to a HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in a PUCCH used to feed back HARQ-ACK for the multi-TTI PDSCH.

[0063] Step S12: 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 one target time slot that corresponds one-to-one with each time slot group, where the time slot group includes at least one time slot, and the target time slot is one time slot that is simultaneously included in the first time slot set and the second time slot set.

[0064] Step S13: determine a logical HARQ-ACK in the target time slot based on the HARQ-ACK in each time slot of each time slot group and the HARQ-ACK in the target time slot corresponding to the time slot group.

[0065] Step S14: Send the HARQ-ACK codebook containing the logical HARQ-ACK in the target time slot.

[0066] In one embodiment, the first time slot set in step S11 including time slots corresponding to multi-TTI PDSCHs refers to the first time slot set including time slots corresponding to all PDSCHs of the multi-TTI PDSCHs.

[0067] In one embodiment, the first time slot set in step S11 includes time slots corresponding to a multi-TTI PDSCH, which refers to the first time slot set including time slots corresponding to each PDSCH of the multi-TTI PDSCH.

[0068] In one embodiment, the HARQ-ACK codebook is a Type 1 HARQ-ACK codebook.

[0069] In one embodiment, the time slots included in each of the at least one time slot group are consecutive time slots, so that the distribution of the time slots in the divided time slot groups is concentrated.

[0070] 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 that is included in the first time slot set but not included in the second time slot set, and at least one target time slot that is simultaneously included in the first time slot set and the second time slot set are determined, a correspondence relationship between the time slot groups and the target time slot is determined, a HARQ-ACK for each time slot of the time slot group is logically bound to a HARQ-ACK for the corresponding target time slot, a logical HARQ-ACK is obtained, and the logical HARQ-ACK is set as the final HARQ-ACK in the target time slot, so that the HARQ-ACK for the corresponding time slot group is carried by the logical HARQ-ACK in the target time slot, thereby enabling the HARQ-ACK codebook transmitted in the PUCCH indicated by the DCI to feedback HARQ-ACKs for all PDSCHs in the multi-TTI PDSCH.

[0071] An embodiment of the present disclosure provides a method for transmitting HARQ-ACK applied to a user equipment, which includes the following steps 2.1 to 2.4.

[0072] Step 2.1: determine a first time slot set and a second time slot set, where the first time slot set includes time slots corresponding to a multi-TTI PDSCH, the second time slot set includes time slots included in a feedback window corresponding to a HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in a PUCCH used to feed back HARQ-ACK for the multi-TTI PDSCH.

[0073] Step 2.2: Determine at least one time slot group that is included in the first time slot set and not included in the second time slot set, and determine one target time slot that corresponds one-to-one with each time slot group, where the time slot group includes at least one time slot, and the target time slot is one time slot that is simultaneously included in the first time slot set and the second time slot set.

[0074] Step 2.3: Based on the HARQ-ACK in each time slot of each time slot group and the HARQ-ACK in the target time slot corresponding to the time slot group, a logic product Execute the logic product The result of (a) is determined as the logical HARQ-ACK in the target time slot.

[0075] Step 2.4: Send the HARQ-ACK codebook containing the logical HARQ-ACK in the target time slot.

[0076] In one embodiment, the time slots included in each of the at least one time slot group are consecutive time slots, so that the distribution of the time slots in the divided time slot groups is concentrated.

[0077] When the subcarrier spacing (SCS) is 480 KHz or 960 KHz, the time length of the corresponding time slot is very short, so the channel condition changes little across multiple time slots, and the demodulation results of each PDSCH in the multi-TTI PDSCH can be considered consistent. Therefore, even after binding multiple HARQ-ACKs, the HARQ-ACKs of each PDSCH in the multi-TTI PDSCH can be accurately implemented.

[0078] When determining the PUCCH time slot for feeding back the HARQ-ACK, the PUCCH time slot for feeding back the HARQ-ACK is determined based on the value of K1 indicated in the DCI and the time slot position of the last PDSCH of the multi-TTI PDSCH, so that the last PDSCH of the multi-TTI PDSCH is usually included in the feedback window of the HARQ-ACK codebook. Therefore, if there is a time slot group that is included in the first time slot set but not included in the second time slot set, a logical HARQ-ACK can be obtained by logically binding the HARQ-ACK of this time slot group with the HARQ-ACK of the time slot of the last PDSCH of the multi-TTI PDSCH.

[0079] An embodiment of the present disclosure provides a method for transmitting HARQ-ACK applied to a user equipment, which includes the following steps 3.1 to 3.4.

[0080] Step 3.1: determine a first time slot set and a second time slot set, where the first time slot set includes time slots corresponding to a multi-TTI PDSCH, the second time slot set includes time slots included in a feedback window corresponding to a HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in a PUCCH used to feed back HARQ-ACK for the multi-TTI PDSCH.

[0081] 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 time slot group, where the target time slot is a time slot simultaneously included in the first time slot set and the second time slot set.

[0082] Step 3.3: determine a logical HARQ-ACK in the target time slot based on the HARQ-ACK in each time slot of the one time slot group and the HARQ-ACK in the target time slot corresponding to the time slot group;

[0083] Step 3.4: Send the HARQ-ACK codebook containing the logical HARQ-ACK in the target time slot.

[0084] In one embodiment, the time slots included in each of the at least one time slot group are consecutive time slots, so that the distribution of the time slots in the divided time slot groups is concentrated.

[0085] 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 but not included in the second time slot set are determined as one time slot group, and simultaneously one target time slot included in the first time slot set and the second time slot set is determined, a correspondence relationship between the time slot group and the target time slot is determined, a HARQ-ACK of each time slot of the time slot group is logically bound to the HARQ-ACK of the corresponding target time slot to obtain a logical HARQ-ACK, and this logical HARQ-ACK is set as the final HARQ-ACK in the target time slot, so that the HARQ-ACK of the corresponding time slot group is carried by the logical HARQ-ACK in the target time slot, thereby enabling the HARQ-ACK codebook transmitted in the PUCCH indicated by the DCI to feedback HARQ-ACKs of all PDSCHs in the multi-TTI PDSCH.

[0086] An embodiment of the present disclosure provides a method for transmitting HARQ-ACK applied to a user equipment, which includes the following steps 4.1 to 4.4.

[0087] Step 4.1: determine a first time slot set and a second time slot set, where the first time slot set includes time slots corresponding to a multi-TTI PDSCH, the second time slot set includes time slots included in a feedback window corresponding to a HARQ-ACK codebook, and the HARQ-ACK codebook is a HARQ-ACK codebook included in a PUCCH used to feed back HARQ-ACK for the multi-TTI PDSCH.

[0088] Step 4.2: Determine all time slots included in the first time slot set but not included in the second time slot set as a time slot group, and determine a target time slot corresponding to the time slot group, where the target time slot is a time slot simultaneously included in the first time slot set and the second time slot set, and the target time slot is located after the last time slot of the time slot group.

[0089] Step 4.3: Determine a logical HARQ-ACK in the target time slot based on the HARQ-ACK in each time slot of the one time slot group and the HARQ-ACK in the target time slot corresponding to the time slot group.

[0090] Step 4.4: Send the HARQ-ACK codebook containing the logical HARQ-ACK in the target time slot.

[0091] In one embodiment, the time slots included in each of the at least one time slot group are consecutive time slots, so that the distribution of the time slots in the divided time slot groups is concentrated.

[0092] In one example, a multi-TTI PDSCH scheduled by one DCI includes a total of eight PDSCHs, and the slots in which these eight 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, in order.

[0093] The first set K1 set includes four consecutive integer elements, specifically {0, 1, 2, 3}.

[0094] The first interval value T is determined to be the first value in the first set K1 set, ie, 0.

[0095] Determine that the feedback time slot is slot n+7+T, ie, slot n+7, and transmit the HARQ-ACK of the multi-TTI PDSCH scheduled by the DCI in the PUCCH in this feedback time slot.

[0096] The feedback window corresponding to the Type 1 HARQ-ACK codebook that may be included in this PUCCH includes {slot n+7, slot n+6, slot n+5, slot n+4}.
