Description

Codebook setting and receiving method and device, terminal and network side equipment
Technical Field
The present application belongs to the field of communications, and in particular, to a codebook setting and receiving method, a codebook setting and receiving device, a terminal and a network side device.
Background
When a User Equipment (UE, also called a terminal) organizes a hybrid automatic repeat request acknowledgement (HARQ-ACK) bit sequence that needs to be reported at a certain feedback moment, based on a predefined rule and a scheduling condition of a single/multiple carrier uplink/downlink Physical Downlink Shared Channel (PDSCH) transmission that needs to report HARQ-ACK at the feedback moment, a corresponding relation between each downlink PDSCH transmission and a certain bit in the organized HARQ-ACK bit sequence is determined, and this operation is called constructing a HARQ-ACK Codebook (Codebook) or a HARQ-ACK Codebook scheme. The new air interface (NR) Rel-15 employs two HARQ-ACK Codebook schemes: semi-static codebook (Type-1) and dynamic codebook (Type-2).
The semi-static codebook is constructed from the perspective of possible PDSCH reception opportunities, which reserves corresponding HARQ-ACK bits for each possible PDSCH reception opportunity (determined based on higher layer configuration or predetermined TDRA Table; TDRA Table, time domain resource allocation table) based on the feedback Timing configuration table (i.e., higher layer configuration or predetermined K1 Set) and HARQ-ACK feedback time instant (i.e., uplink time slot in which the semi-static codebook is transmitted). If the UE does not actually receive/detect the corresponding PDSCH for a certain PDSCH receiver, setting the corresponding HARQ-ACK bit as NACK, otherwise setting the corresponding HARQ-ACK bit based on the decoding result of the PDSCH.
In the Rel-17.6-71 GHz characteristic research process, it is confirmed that a new subcarrier spacing (SCS) including 480kHz and 960kHz needs to be introduced for a new NR deployment frequency band. For these newly introduced SCS, physical Downlink Control Channel (PDCCH) monitoring needs to be correspondingly adjusted or enhanced, for example, to avoid the need for the UE to monitor PDCCH in each Slot (with a very short duration), so as to reduce UE implementation complexity. Accordingly, in order to fully utilize the carrier time domain resources, multi PDSCH (Multi-PDSCH) scheduling and Multi physical uplink shared channel (Multi-PUSCH) scheduling need to be studied/introduced.
Multi-PDSCH scheduling refers to the ability of a single Downlink Control Information (DCI) to schedule multiple PDSCH transmissions on the same carrier at once. The PDSCH is not overlapped with each other in the time domain according to the protocol of NR.
However, when Multi-PDSCH scheduling is supported, the feedback method for the HARQ-ACK semi-static codebook in the prior art has the problems of complex codebook construction flow and larger feedback load.

The codebook setting, receiving method, device, terminal and network side device provided by the embodiment of the application are described in detail below through some embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 2, an embodiment of the present application provides a codebook setting method, including:
Step 201, under the condition that a single downlink control information DCI can schedule at least two physical downlink shared channels PDSCH, a terminal determines a bit sequence of a hybrid automatic repeat request acknowledgement HARQ-ACK codebook according to a target feedback time offset set and an equivalent time domain resource allocation table;
it should be noted that, each row in the equivalent time domain resource allocation table corresponds to one time domain resource allocation record, and alternatively, the time domain resource allocation record may be a Start Length Indication (SLIV) record.
Step 202, a terminal sets the bit value of the HARQ-ACK codebook based on the scheduling PDSCH to be fed back;
the scheduled PDSCH to be fed back is scheduled by one to a plurality of DCIs, and each of the one to a plurality of DCIs schedules one to a plurality of PDSCHs.
It should be noted that, multi-PDSCH (Multi-PDSCH) scheduling mainly includes two HARQ-ACK feedback modes:
HARQ-ACK feedback method I, at least two PDSCH scheduled by single DCI feeds back HARQ-ACK on the same PUCCH
Note that this way refers to that all PDSCH scheduled by a single DCI feeds back HARQ-ACK on the same PUCCH, and fig. 3 gives an example in which all PDSCH scheduled by a single DCI feeds back HARQ-ACK on one PUCCH.
And the HARQ-ACK feedback mode II feeds back the HARQ-ACK on at least two Physical Uplink Control Channels (PUCCHs) by at least two PDSCHs scheduled by single DCI.
It should be noted that, this way refers to that all PDSCH scheduled by a single DCI feedback HARQ-ACK on different PUCCHs, and it is assumed that PDSCH feeding back corresponding HARQ-ACKs on the same PUCCH forms a PDSCH subset, (optionally, the number/index of corresponding SLIV in a corresponding row of one to multiple PDSCH included in each PDSCH subset is continuous in a time domain resource allocation table (TDRA Table)), each PDSCH subset may correspond to a value of feedback time offset (in an example form, K1 value), and the starting reference point of this K1 value application is the time unit where the end time of the last PDSCH (time later) in this PDSCH subset is located, where the time unit may be a time slot or a sub-slot, such as an uplink time slot or a sub-slot. Fig. 4 gives one example of feedback HARQ-ACKs on multiple PUCCHs for multiple PDSCH scheduling of a single DCI.
It should be noted that, when the terminal performs codebook setting in the HARQ-ACK feedback mode one and the HARQ-ACK feedback mode two, the above-mentioned step 201 and step 202 need to be implemented.
The implementation procedures of step 201 and step 202 are described in detail below.
Alternatively, one implementation manner of the step 201 may be:
Acquiring a target feedback time offset set and a first time domain resource allocation table corresponding to a first feedback time offset in the target feedback time offset set;
For a first feedback time offset in the target feedback time offset set, acquiring an equivalent time domain resource allocation table corresponding to the first feedback time offset according to a first time domain resource allocation table corresponding to the first feedback time offset;
And determining a bit sequence of the HARQ-ACK codebook according to the target feedback time offset set and an equivalent time domain resource allocation table corresponding to the first feedback time offset in the target feedback time offset set.
The first feedback time offset may be any one of the feedback time offsets in the target feedback time offset set, or the first feedback time offset may be any one of the feedback time offsets in the target feedback time offset set. The embodiment of the present application will be described by taking the first feedback time offset as any feedback time offset in the target feedback time offset set as an example, and the case where the first feedback time offset is any one of the partial feedback time offsets in the target feedback time offset set may be implemented in a similar manner.
Optionally, taking the first feedback time offset as an example, where any feedback time offset in the target feedback time offset set is taken as an example, one implementation manner of the step 201 may be:
step 2011, acquiring a target feedback time offset set and a first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set;
Step 2012, for each feedback time offset in the target feedback time offset set, acquiring an equivalent time domain resource allocation table corresponding to each feedback time offset according to the first time domain resource allocation table corresponding to each feedback time offset;
And step 2013, determining a bit sequence of the HARQ-ACK codebook according to the target feedback time offset set and an equivalent time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set.
It should be noted that the implementation of step 201 described above is applicable to both HARQ-ACK feedback, but there are some differences in implementation of certain specific steps.
For step 2011, optionally, in the case of HARQ-ACK feedback mode one or single DCI scheduling one PDSCH, one implementation manner that may be adopted in step 2011 is:
And determining the target feedback time offset set as an original feedback time offset set, wherein a first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set is the same as the original time domain resource allocation table.
It should be noted that the above and the following original feedback time offset sets may be feedback time offset sets configured by a higher layer, or feedback time offset sets predetermined or known by other means (e.g., a protocol agreed manner). Alternatively, one example form of feedback time offset is K1, which is used to indicate an offset of the time domain position of the HARQ-ACK feedback relative to the time domain position of the PDSCH transmission, which can be extended herein to indicate an offset of the time domain position of the HARQ-ACK feedback relative to the time domain position of the PDSCH subset. The time domain position of the PDSCH subset may be the end time of the last PDSCH corresponding to this PDSCH subset. Optionally, K1 may be understood as an offset between a time unit at which an end time of a last PDSCH corresponding to the PDSCH subset is located and a time unit at which HARQ-ACK feedback corresponding to the PDSCH subset is located, where the offset unit is a time unit, and may be a time slot or a sub-slot.
The original time domain resource allocation table described above and subsequently described may be a high level configured time domain resource allocation table (TDRA Table) or a feedback time offset set that is predetermined or known by other means (e.g., by protocol conventions). TDRA Table each row corresponds to at least one PDSCH transmission scheduled by one DCI.
For step 2011, optionally, in the case of the HARQ-ACK feedback mode two, the implementation manner that may be adopted in step 2011 includes one of the following:
A11, determining a target feedback time offset set as an original feedback time offset set, wherein a first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set is the same as the original time domain resource allocation table;
In this way, the HARQ-ACK feedback method two may be implemented in the same manner as the HARQ-ACK feedback method one.
A12, determining a target feedback time offset set according to a preset mode, and acquiring a first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set;
Optionally, in this case, the higher layer configuration or the predetermined TDRA Table is extended, and the extension TDRA Table is considered herein mainly because when the PDSCH corresponding to only part SLIV of a certain row in the higher layer configuration or the predetermined TDRA Table feeds back the corresponding HARQ-ACK on a certain semi-static codebook, if the extension is not made, the constructed semi-static codebook may not have Occasion (candidate transmission opportunity, which may be understood as PDSCH candidate transmission opportunity, or PDSCH subset candidate transmission opportunity) corresponding to this part of the row, so that the corresponding HARQ-ACK cannot be actually fed back for these PDSCH.
Optionally, in this case, the higher layer configuration or the predetermined K1 Set (K1 Set) is extended, where the extension K1 Set is considered mainly because some additional K1 may be derived with respect to the higher layer configuration or the predetermined K1 Set based on a different scheme indicating multiple PUCCHs, and if the extension is not performed, the constructed semi-static codebook may not have Occasion corresponding to these additional K1, so that HARQ-ACKs corresponding to PDSCH corresponding to these additional K1 cannot be fed back in practice.
Optionally, the preset mode includes one of the following:
A121, splitting a first target row corresponding to a first PDSCH subset in the original time domain resource allocation table under the condition that a first feedback time offset corresponding to the first PDSCH subset is selected from an original feedback time offset set, and updating the original time domain resource allocation table according to the PDSCH subset; determining a target feedback time offset set as an original feedback time offset set, wherein a first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set is an updated original time domain resource allocation table;
For example, when K1 corresponding to a certain PDSCH subset can only be selected from the higher-layer configuration or the predetermined K1 Set, only the rows in the higher-layer configuration or the predetermined TDRA Table need to be expanded or replaced first, and then the subsequent operation in step 201 is performed based on the updated TDRA Table.
It should be noted that the equivalent TDRA Table is also expanded or replaced synchronously because it is determined based on the updated higher-level configuration or the predetermined TDRA Table. Operations to expand or replace a row in TDRA Table include: new rows (each corresponding to the time domain resource allocation of each PDSCH contained in any one of the partitioned PDSCH subsets) obtained after a certain row in TDRA Table is partitioned into PDSCH subset(s) are added/extended into TDRA Table. The foregoing splitting operations are performed one by one for each row in the original TDRA Table (it will be appreciated that the foregoing splitting operations need only be performed for rows containing a plurality of SLIV), resulting in updated TDRA Table.
Optionally, in this case, the implementation of splitting the first PDSCH subset according to the PDSCH subset and updating the original time domain resource allocation table according to the corresponding first target row in the original time domain resource allocation table includes one of the following:
a1211, adding at least two new lines obtained by splitting the first target line according to the PDSCH subset into the original time domain resource allocation table under the condition that the first target line supports not to divide the PDSCH subset to be scheduled and supports to divide the PDSCH subset to be scheduled;
That is, if a certain row may be scheduled without dividing the PDSCH subsets (i.e., all PDSCH corresponding to the row are fed back HARQ-ACKs on the same PUCCH), or may be scheduled with dividing the PDSCH subsets, then the operation of splitting the row in the higher layer configuration or predetermined TDRA Table is performed, and the original row in the higher layer configuration or predetermined TDRA Table is reserved, for example, when the first row in the higher layer configuration or predetermined TDRA Table includes two PDSCH subsets, and when the splitting operation is performed on the first row, then after splitting is completed, 3 rows, i.e., the original first row, and two rows corresponding to the PDSCH subsets (i.e., one row of each PDSCH subset) are obtained.
A1212, adding at least two new rows obtained by splitting the first target row according to the PDSCH subset to the original time domain resource allocation table and deleting the first target row in the original time domain resource allocation table under the condition that the first target row supports the scheduling of dividing the PDSCH subset and does not support the scheduling of not dividing the PDSCH subset;
That is, if a certain line can only be scheduled to divide PDSCH subsets, this line is deleted from the higher layer configuration or the predetermined TDRA Table when or before/after adding/expanding a new line obtained by dividing a certain line into PDSCH subsets into TDRA Table; it should be noted that the operation of splitting the row is the same as that in a1211, except that the split row is reserved in a1211, and in this implementation, after the splitting is completed, the split row is deleted.
A122, under the condition that a second feedback time offset corresponding to a second PDSCH subset is determined based on feedback time offset indicated by DCI and a first preset rule, determining an initial value of a target feedback time offset set as an original feedback time offset set, wherein the initial value of a first time domain resource allocation table corresponding to a first target feedback time offset (the first target feedback time offset is any feedback time offset belonging to the original feedback time offset set) in the target feedback time offset set is the same as the original time domain resource allocation table, splitting the second PDSCH subset in a second target row corresponding to the original time domain resource allocation table according to the PDSCH subset, and updating the target feedback time offset set and the first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set;
It should be noted that, the second feedback time offset is determined according to the feedback time offset indicated by the DCI and the first preset rule, and may be referred to as an additional feedback time offset, and specifically, the additional feedback time offset may be obtained by using an acquisition manner including:
The single feedback time offset (e.g., K1) indicated in the DCI may be applied to the first/last/designated PDSCH subset of the schedule, and feedback time offsets (e.g., K1) corresponding to other PDSCH subsets may be sequentially incremented/decremented based on the subset index based on the indicated single feedback time offset (e.g., K1). When a single feedback time offset (e.g., K1) indicated in DCI is applied to a specified PDSCH subset, feedback time offsets (e.g., K1) corresponding to PDSCH subsets having numbers/indices smaller than those of the specified PDSCH subset may be determined in a sequentially decreasing manner, and feedback time offsets (e.g., K1) corresponding to PDSCH subsets having numbers/indices larger than those of the specified PDSCH subset may be determined in a sequentially increasing manner.
Any of the feedback time offsets determined for the other PDSCH subsets described above, when not in the original feedback time offset set, would be in the additional feedback time offset.
The step size of the increment/decrement may be 1, or may be a specified value (specified by a protocol or configured by a higher layer, or determined based on a preset rule).
Optionally, when determining the feedback time offset (e.g., K1) corresponding to the other PDSCH subset based on the increment/decrement rule, if the determined feedback time offset (e.g., K1) corresponding to a certain PDSCH subset (assuming index is i) corresponds to an illegal time cell, the time cell is ignored/skipped, and the next time cell is continuously checked along a predetermined direction (the direction of increasing forward/along the feedback time offset (e.g., K1) and decreasing backward/along the feedback time offset (e.g., K1)) until the determined feedback time offset (e.g., K1) does not correspond to the illegal time cell, the determining of the feedback time offset (e.g., K1) corresponding to the next PDSCH subset (assuming index is i+1 or i-1) may apply a step size and ensure not to correspond to the illegal time cell based on the feedback time offset (e.g., K1) ultimately corresponding to the PDSCH subset, or may ensure not to correspond to the illegal time cell based on the initial feedback time offset (e.g., K1) determined based on the step size (without considering the feedback time offset (e.g., K1) change due to the illegal time cell). Optionally, the UE determines the feedback time offset (e.g. K1) corresponding to each PDSCH subset directly based on the step size and the single feedback time offset (e.g. K1) indicated in the DCI, and does not expect the feedback time offset (e.g. K1) corresponding to any PDSCH subset to correspond to an illegal time unit.
The above time unit may be understood as a Slot (Slot) or Sub-Slot (Sub-Slot), and may correspond to an uplink Slot/Sub-Slot. The illegal time unit may be understood that all time domain symbols corresponding to Slot/Sub-Slot corresponding to the feedback time offset (e.g. K1) are downlink, or at least one of symbols occupied by PUCCH Resource (Resource) determined in Slot/Sub-Slot corresponding to the feedback time offset (e.g. K1) is a Semi-static downlink Symbol (Semi-static DL Symbol)/Semi-static flexible Symbol (Semi-static Flexible Symbol)/synchronization signal block Symbol (SSB Symbol)/control Resource set0 Symbol (CORESET 0 Symbol).
It should be noted that, when K1 corresponding to a certain PDSCH subset is derived based on a value selected from a higher-layer configuration or a predetermined K1 Set, and a first preset rule (a certain predefined rule/rules), when determining Occasion sets, in addition to various combinations of original K1 and rows, additional consideration needs to be given to the combination of new rows (which may be understood as a part or a segment of the original rows) corresponding to these PDSCH subsets and the corresponding K1.
The operation of additionally considering the combination of the new row corresponding to the PDSCH subset and its corresponding K1 includes: for new rows (each corresponding to the time domain resource allocation of each PDSCH included in any one of the divided PDSCH subsets) obtained by dividing one of TDRA Table rows into PDSCH subset(s), combining with corresponding K1 (K1 in a higher-level configuration or a predetermined K1 Set) possibly applied based on the K1 indication and a predefined rule, or additional K1 derived/derived based on K1 in a higher-level configuration or a predetermined K1 Set and a certain predefined rule, various possible new row+corresponding K1 combinations are obtained, expanding TDRA Table (refer to the corresponding operation in a 121) corresponding to each K1 in a higher-level configuration or a predetermined K1 Set, and determining new row sets corresponding to each additional K1, and adding these additional K1 to the higher-level configuration or predetermined K1 Set as input for executing step 201. It will be appreciated that for any K1 in a higher-level configuration or a predetermined K1 Set, when there is any new row+this K1 possible combination, it is necessary to expand this K1, the higher-level configuration or predetermined TDRA Table to include this/these new rows, and determine the equivalent TDRA Table corresponding to this K1 based on the expanded higher-level configuration or predetermined TDRA Table; for any additional K1, the equivalent TDRA Table corresponding to this additional K1 will be determined based on its corresponding new set of rows, rather than based on the higher-level configuration or predetermined TDRA Table (when performing the correlation operation for this additional K1, and a certain row of the higher-level configuration or predetermined TDRA Table in step 202, it may be understood that the correlation operation is actually performed for a certain row of this new set of rows).
Optionally, in this case, an implementation manner of splitting the second PDSCH subset in the original time domain resource allocation table according to the second target row and updating the target feedback time offset set and the first time domain resource allocation table corresponding to each feedback time offset in the target feedback time offset set may include one of the following:
A1221, adding a target new line obtained by splitting the second target line according to the PDSCH subset to a first time domain resource allocation table corresponding to a second target feedback time offset when the second target feedback time offset does not belong to the target feedback time offset set, wherein the second target line supports that the PDSCH subset is not divided and the PDSCH subset is not divided;
it should be noted that, the target new row corresponds to a new row of any subset of the second PDSCH subsets, the second target feedback time offset corresponds to the target new row, and the second target feedback time offset may belong to the original feedback time offset set, or be an additional feedback time offset; the additional feedback time offset is determined based on the first preset rule and does not belong to the original feedback time offset set, and an initial value of a first time domain resource allocation table corresponding to the additional feedback time offset before any new row is not added is empty.
That is, if a certain row may be scheduled without dividing the PDSCH subset (i.e. all PDSCH corresponding to the row are fed back HARQ-ACK on the same PUCCH), or may be scheduled with dividing the PDSCH subset, the operation of dividing the row is performed, the combination of each new row+the corresponding K1 after the division is added to the first time domain resource allocation table corresponding to K1, and when the corresponding K1 (or the corresponding feedback time offset) does not belong to the target feedback time offset set, the corresponding K1 needs to be added in the target feedback time offset set.
A1222, adding a new target row obtained by splitting the second target row according to the PDSCH subset to a first time domain resource allocation table corresponding to a second target feedback time offset when the second target row supports that the PDSCH subset is scheduled and does not support that the PDSCH subset is not scheduled, adding the second target feedback time offset to the target feedback time offset set when the second target feedback time offset does not belong to the target feedback time offset set, and deleting the second target row from a first time domain resource allocation table corresponding to a third target feedback time offset;
Wherein the target new behavior corresponds to a new row of any one of the second PDSCH subsets; the second target feedback time offset corresponds to the target new line, and the second target feedback time offset may belong to the original feedback time offset set, or be an additional feedback time offset; the additional feedback time offset is determined based on the first preset rule and does not belong to the original feedback time offset set, and an initial value of a first time domain resource allocation table corresponding to the additional feedback time offset before any new row is not added is empty; the third target feedback time offset is any feedback time offset located in the target feedback time offset set and belonging to the original feedback time offset set.
That is, if a certain row can only divide PDSCH subsets and is scheduled, for any K1 in the higher layer configuration or the predetermined K1 Set, the row needs to be deleted from the higher layer configuration or the predetermined TDRA Table, where the operation of splitting the row is the same as the splitting operation in a1221, except that the split row is reserved in the first time domain resource allocation table corresponding to each feedback time offset in the original feedback time offset Set in a1221, and in this implementation, after splitting is completed, the split row is deleted from the first time domain resource allocation table corresponding to each feedback time offset in the original feedback time offset Set.
It should be further noted that it is only necessary to operate on the line a121 or a122 including the plurality SLIV. The determination of either K1 for the higher-level configuration or the predetermined K1 Set, or any additional K1, for the necessary extension of either the higher-level configuration or the predetermined TDRA Table, or for the corresponding TDRA Table, and the determination of the equivalent TDRA Table, may be done independently and not (between K1) affect each other.
It should be noted that, for step 201, only the implementation of step 2011 in different feedback modes is different in different HARQ-ACK feedback modes, and the remaining steps 2012 and 2013 are applicable to both HARQ-ACK feedback modes.
The implementation of step 2012 and step 2013 is described as follows.
For step 2012, a first implementation that may be employed is:
20121, performing conflict row deletion processing on the first time domain resource allocation table corresponding to each feedback time offset, and obtaining a second time domain resource allocation table corresponding to each feedback time offset;
It should be noted that an alternative implementation of this step is: for each row in a first time domain resource allocation table corresponding to each feedback time offset, if a third target row exists and meets a first condition, deleting the third target row from the first time domain resource allocation table;
Wherein the first condition is: PDSCH corresponding to at least one time domain resource allocation record configured in the third target row collides with Semi-static uplink symbol (Semi-static UL symbol).
20122, Acquiring an equivalent time domain resource allocation table corresponding to each feedback time offset according to the second time domain resource allocation table corresponding to each feedback time offset;
It should be noted that an alternative implementation of this step 20122 is: and reserving one time domain resource allocation record of a preset position in each row aiming at each row in the second time domain resource allocation table corresponding to each feedback time offset to obtain an equivalent time domain resource allocation table corresponding to each feedback time offset.
That is, in this implementation, whether to conflict with and delete the conflict line is determined based on the high-level configuration or the predetermined line TDRA Table, and in this implementation, the high-level configuration or the predetermined line TDRA Table is uniformly deleted and then the equivalent time domain resource allocation table is acquired. For example, when Multi-PDSCH scheduling is supported, each row in the higher layer configuration or predetermined TDRA Table corresponds to single or multiple SLIV, and time domain resource allocation information of single or multiple PDSCH. Assuming here that the Semi-static codebook is transmitted in an upstream or sub-slot n, given a certain K1 of the higher layer configuration or the predetermined K1 Set, whether a certain line of the higher layer configuration or the predetermined TDRA Table collides with the Semi-static UL symbol may be determined as follows: assuming that this K1 is applied to this row, if none of the PDSCH corresponding to each SLIV configured in this row collides with any Semi-static UL symbol, it is determined that this row does not collide with the Semi-static UL symbol, otherwise it is determined that there is a collision, and this manner of processing for higher layer configuration or predetermined TDRA Table is referred to as time domain erasure manner 1.
For step 2012, a second implementation that may be employed is:
And performing conflict row deletion processing on the first time domain resource allocation table corresponding to each feedback time offset, and reserving one time domain resource allocation record of a preset position for each row which does not conflict in the first time domain resource allocation table corresponding to each feedback time offset to obtain an equivalent time domain resource allocation table corresponding to each feedback time offset.
Optionally, the performing conflict row deletion processing on the first time domain resource allocation table corresponding to each feedback time offset may adopt an implementation manner:
For each row in a first time domain resource allocation table corresponding to each feedback time offset, if a third target row exists and meets a first condition, deleting the third target row from the first time domain resource allocation table;
Wherein the first condition is: and the PDSCH corresponding to the at least one time domain resource allocation record configured in the third target row collides with the semi-static uplink symbol.
That is, in this implementation, whether to conflict and delete conflicting rows is also determined based on a higher level configuration or predetermined TDRA Table rows, but this implementation differs from the above in that: in this method, the equivalent time domain resource allocation table is acquired while the deletion process is performed on the higher layer configuration or the predetermined TDRA Table, and the method of processing the higher layer configuration or the predetermined TDRA Table is referred to as time domain deletion method 1.
Optionally, the present application further provides another way to perform the conflict row deletion processing, that is, before step 2013, the method further includes:
and performing conflict row deletion processing on the equivalent time domain resource allocation table corresponding to each feedback time offset.
Optionally, the performing conflict row deletion processing on the equivalent time domain resource allocation table corresponding to each feedback time offset may be implemented as follows:
For each row in the equivalent time domain resource allocation table corresponding to each feedback time offset, if a fourth target row exists and meets a second condition, deleting the fourth target row in the equivalent time domain resource allocation table;
wherein the second condition is: and the PDSCH corresponding to the time domain resource allocation record in the fourth target row collides with the semi-static uplink symbol.
It should be noted that this way is to determine whether or not to conflict and delete the conflict line based on the line in the equivalent TDRA Table. As can be seen from the foregoing description, each row in the equivalent TDRA Table corresponds to only a single (reserved) SLIV, and each row corresponds one-to-one to the same numbered/indexed row in the higher-level configuration or in the predetermined TDRA Table. Assuming here that the Semi-static codebook is transmitted in an upstream or sub-slot n, given a certain K1 in a higher layer configuration or a predetermined K1 Set, whether a certain line in the equivalent TDRA Table collides with the Semi-static UL symbol can be determined as follows: assuming that this K1 is applied for this row, if the PDSCH corresponding to a single SLIV in this row (the slot or sub-slot in which the corresponding PDSCH is located needs to be determined in conjunction with the location of this single SLIV in the corresponding row in the higher-layer configuration or in the predetermined TDRA Table) does not collide with any Semi-static UL symbol, then this row is determined not to collide with the Semi-static UL symbol, otherwise a collision is determined to exist, and this way of handling for equivalent TDRA Table is referred to as time domain erasure 2.
It can be understood that when the semi-static codebook construction procedure specified in the existing protocol is followed, for any K1 in the higher layer configuration or the predetermined K1 Set, the time domain deletion mode 1 (based on the collision judgment of the rows in the higher layer configuration or the predetermined TDRA Table) or the time domain deletion mode 2 (based on the collision judgment of the rows in the equivalent TDRA Table) can be adopted to determine the equivalent TDRA Table corresponding to the higher layer configuration or the predetermined K1 Set, then for all the rows in the equivalent TDRA Table, the 0, 1 or more Occasion corresponding to the K1 are determined based on the Pruning/Grouping operation, and the Set Occasion corresponding to the HARQ-ACK codebook is obtained after the end-to-end concatenation of the Occasion corresponding to each K1 in the preset order, and the corresponding HARQ-ACK bit sequence can be determined based on the Set Occasion.
It should be noted that each Occasion corresponds to a single subset of the time domain resource allocation records of a certain K1, which is used as a basis of the following step 202.
Setting a bit value for a bit sequence of the HARQ-ACK codebook output in the step 201 based on a scheduling PDSCH of the HARQ-ACK to be fed back; when a certain scheduled PDSCH cannot find a corresponding Occasion based on the correspondence determined in step 201, its corresponding Occasion needs to be determined based on a predefined rule; when a certain Occasion corresponds to more than 1 scheduled PDSCH, time Domain Bundling operations are performed on the decoding results of these scheduled PDSCH, and the HARQ-ACK bit corresponding to this Occasion is set based on the operation results.
Optionally, the implementation manner that the step 202 may be adopted includes one of the following:
Determining a PDSCH position set corresponding to each candidate transmission opportunity, and setting the value of a HARQ-ACK bit corresponding to each candidate transmission opportunity in the HARQ-ACK codebook according to the PDSCH position set;
In the second implementation manner, a corresponding candidate transmission opportunity is determined for each first PDSCH, and the value of a corresponding HARQ-ACK bit of each candidate transmission opportunity in the HARQ-ACK codebook is set;
the first PDSCH is a PDSCH requiring feedback of the corresponding HARQ-ACK in the HARQ-ACK codebook.
These two implementations are each described in detail below.
1. For implementation one
Alternatively, the implementation procedure that can be adopted by this implementation manner is:
step 20211, determining a candidate transmission opportunity corresponding to each time domain feedback record according to a second preset rule;
Step 20212, determining, according to the candidate transmission opportunities corresponding to each time domain feedback record, a PDSCH position set corresponding to each candidate transmission opportunity, where one PDSCH position in the PDSCH position set corresponds to one time domain feedback record;
step 20213, setting a value of a HARQ-ACK bit corresponding to each candidate transmission opportunity in the HARQ-ACK codebook according to PDSCH receiving or detecting conditions of each PDSCH position in the PDSCH position set corresponding to each candidate transmission opportunity;
When one or more corresponding PDSCH is received/detected by the UE for a certain Occasion, the corresponding HARQ-ACK bit in the codebook is set Occasion based on the result obtained by Time domain bundling of the decoding result of the one or more corresponding PDSCH.
When the UE does not receive/detect any PDSCH for a certain Occasion, this Occasion sets the corresponding HARQ-ACK bit in the codebook to a default NACK.
Wherein the second preset rule includes at least one of:
B11, for each feedback time offset in the target feedback time offset set and each row in the first time domain resource allocation table corresponding to each feedback time offset, determining a time domain feedback record corresponding to each time domain resource allocation record in each row and a candidate transmission opportunity corresponding to the time domain feedback record;
It should be noted that, when the first time domain resource allocation table performs the deletion processing of the conflict row in the previous step, the first time domain resource allocation table may be directly applied herein, but if the first time domain resource allocation table does not perform the deletion processing of the conflict row in the previous step, in an optional case, before executing each feedback time offset in the target feedback time offset set and each row in the first time domain resource allocation table corresponding to each feedback time offset, determining the time domain feedback record corresponding to each time domain resource allocation record in each row and the candidate transmission opportunity corresponding to the time domain feedback record, the method further includes:
for each row in the first time domain resource allocation table corresponding to each feedback time offset, if a fifth target row exists and meets a third condition, deleting the fifth target row;
wherein the third condition is: PDSCH corresponding to at least one time domain resource allocation record configured in the fifth target row collides with semi-static uplink symbols.
In this case, the PDSCH corresponding to all the time domain resource allocation records in each row of the first time domain resource allocation table is directly determined to collide with the semi-static uplink symbol, and the row is deleted as long as there is a conflict between the PDSCH corresponding to one time domain resource allocation record and the semi-static uplink symbol.
In another alternative case, before determining, for each feedback time offset in the target feedback time offset set and for each row in the first time domain resource allocation table corresponding to each feedback time offset, a time domain feedback record corresponding to each time domain resource allocation record in each row and a candidate transmission opportunity corresponding to the time domain feedback record, the method further includes:
for each row in the first time domain resource allocation table corresponding to each feedback time offset, if a sixth target row exists and meets a fourth condition, deleting the sixth target row;
Wherein the fourth condition is: and the PDSCH corresponding to the time domain resource allocation record in the row corresponding to the sixth target row in the first equivalent time domain resource allocation table is in conflict with the semi-static uplink symbol, wherein the first equivalent time domain resource allocation table corresponds to the first time domain resource allocation table in which the sixth target row is positioned.
It should be noted that, since there is only one time domain resource allocation record in each row in the equivalent time domain resource allocation table, that is, in this case, the PDSCH corresponding to the time domain resource allocation record in the specific position of each row in the first time domain resource allocation table (that is, the time domain resource allocation record reserved in the equivalent time domain resource allocation table) is directly subjected to collision judgment with the semi-static uplink symbol, and if the PDSCH corresponding to the time domain resource allocation record in the specific position collides with the semi-static uplink symbol, the row is deleted.
It should be noted that, the foregoing performing is a deletion processing for a collision line, and the present application further provides a deletion processing manner for a time domain resource allocation record, and optionally, before determining, for each feedback time offset in the target feedback time offset set and each line in the first time domain resource allocation table corresponding to each feedback time offset, a time domain feedback record corresponding to each time domain resource allocation record in each line, and a candidate transmission opportunity corresponding to the time domain feedback record, the method further includes:
And aiming at each time domain resource allocation record in each row in a first time domain resource allocation table corresponding to each feedback time offset, if the PDSCH corresponding to a first target time domain resource allocation record collides with a semi-static uplink symbol, deleting the first target time domain resource allocation record in the row where the first target time domain resource allocation record is located.
For example, there are two rows in the first time domain resource allocation table, where the first row has two time domain resource allocation records and the second row has three time domain resource allocation records; when the PDSCH corresponding to the second time domain resource allocation record in the first row collides with the semi-static uplink symbol, the second time domain resource allocation record needs to be deleted in the first row, and when the PDSCH corresponding to the first time domain resource allocation record in the second row collides with the semi-static uplink symbol, the first time domain resource allocation record needs to be deleted in the second row.
After ensuring that each row in the first time domain resource allocation table or each time domain resource allocation record does not collide with the semi-static uplink symbol, for each feedback time offset in the target feedback time offset set and each row in the first time domain resource allocation table corresponding to each feedback time offset, determining a time domain feedback record corresponding to each time domain resource allocation record in each row, and an alternative implementation manner of a candidate transmission opportunity corresponding to the time domain feedback record is as follows:
Determining a time domain feedback record corresponding to each time domain resource allocation record in each row in the first time domain resource allocation table corresponding to each feedback time offset, and determining a candidate transmission opportunity corresponding to the time domain feedback record according to a first preset condition and a second preset condition (in an alternative implementation, the first preset condition and the second preset condition are required to be met simultaneously);
Wherein, the first preset condition is: the reference equivalent feedback time offset corresponding to the target time domain feedback record is equal to the reference feedback time offset corresponding to the target candidate transmission opportunity;
the second preset condition includes at least one of the following:
B111, the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity comprises a reference time domain resource allocation record corresponding to the target time domain feedback record;
B112, the starting symbol of the reference time domain resource allocation record corresponding to the target time domain feedback record is not later than the earliest ending symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
B113, the subset of the reference time domain resource allocation records corresponding to the target candidate transmission opportunity meets a third preset condition;
And B114, the third preset condition is as follows: and the starting symbol of the reference time domain resource allocation record corresponding to the target time domain feedback record is not earlier than the earliest starting symbol of the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity, and the ending symbol of the reference time domain resource allocation record corresponding to the target time domain feedback record is not later than the latest ending symbol of the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity.
Here, it should be further noted that, when there are a plurality of the target candidate transmission opportunities that satisfy the third preset condition, the method further includes:
selecting one of a plurality of target candidate transmission opportunities according to a fourth preset condition;
wherein the fourth preset condition includes one of:
b1141, selecting the smallest sequence number of the target candidate transmission opportunity;
B1142, selecting the earliest starting symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
It should be noted that, the earliest start symbol in the reference time domain resource allocation record subset refers to the start symbol of SLIV whose start symbol in the reference time domain resource allocation record subset is earliest.
B1143, selecting the earliest ending symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
It should be noted that, the earliest ending symbol in the subset of reference time domain resource allocation records refers to the ending symbol of SLIV which is the earliest starting symbol in the subset of reference time domain resource allocation records.
B1144, selecting the earliest ending symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
The latest ending symbol in the reference time domain resource allocation record subset refers to the ending symbol of SLIV in the reference time domain resource allocation record subset.
The implementation modes are as follows: for a given K1, and a given row, the determination of the (SLIV, equivalent K1) record (an example form of the instant domain feedback record) corresponding to each SLIV in this row, and the correspondence with Occasion in the codebook, can be done as follows:
For a record of (SLIV, equivalent K1), SLIV corresponds to a certain SLIV in a given row in TDRA Table, and equivalent K1 is the K1 value actually applied when the HARQ-ACK corresponding to this SLIV is fed back in the uplink slot or sub-slot n, it can be understood that the end time of the PDSCH corresponding to this SLIV (when the DCI is scheduled by downlink by indicating the given row and the given K1, this SLIV can determine the time domain position thereof, or the time slot or sub-slot in the given row) is located in the [ uplink ] slot or sub-slot and the time domain offset (expressed by granularity of a single uplink slot or sub-slot) between the uplink slot or sub-slot n. In determining the equivalent K1, the following may be used: the equivalent k1=the time domain offset (expressed in terms of granularity of a single uplink slot or sub-slot, i.e. time domain offset=m2-m 1) between the uplink slot or sub-slot m1 where the end time of k1+ SLIV indicated is located and the uplink slot or sub-slot m2 where the end time of the last SLIV in a given row is located.
For some SLIV (assuming that the target time domain feedback record corresponds) and some Occasion (assuming that a subset of the time domain resource allocation records (assuming that the subset of the time domain resource allocation records corresponds to the reference feedback time offset), when this SLIV corresponds to this Occasion, the reference feedback time offset corresponding to the reference equivalent feedback time offset= Occasion corresponding to the target time domain feedback record needs to be satisfied at the same time, and a second preset condition.
B12, respectively corresponding each time domain resource allocation record which does not correspond to the candidate transmission opportunity to the target candidate transmission opportunity;
optionally, one implementation that may be employed in this case includes:
For a first time domain resource allocation record which does not correspond to a candidate transmission opportunity, acquiring a candidate transmission opportunity corresponding to a target time domain resource allocation record with the corresponding candidate transmission opportunity in a row of the first time domain resource allocation record, and taking the candidate transmission opportunity corresponding to the target time domain resource allocation record as the candidate transmission opportunity corresponding to the first time domain resource allocation record;
it should be noted that, in either the HARQ-ACK feedback scheme one or the HARQ-ACK feedback scheme two, each time domain resource allocation record that does not correspond to a candidate transmission opportunity needs to be respectively corresponding to a target candidate transmission opportunity in this way.
It should be noted that, in the first HARQ-ACK feedback method, the target candidate transmission opportunity of each time domain resource allocation record that does not correspond to the candidate transmission opportunity may be obtained, but in the second HARQ-ACK feedback method, when the PDSCH corresponding to only part SLIV of a certain row in the higher-layer configuration or the predetermined TDRA Table feeds back the corresponding HARQ-ACK on a certain semi-static codebook, the constructed semi-static codebook may not have Occasion corresponding to the part of the row (because the new row corresponding to the part SLIV may apply a certain K1 in the higher-layer configuration or the predetermined K1 Set, but any SLIV of the part does not have Occasion corresponding thereto, or the new row applies a certain additional K1, and the additional K1 does not have the corresponding Occasion). Thus, in this case, in the case where the candidate transmission opportunity corresponding to the target time domain resource allocation record in which the candidate transmission opportunity exists in the row where the first time domain resource allocation record is not acquired, it should further include:
Acquiring a target candidate transmission opportunity corresponding to the first time domain resource allocation record according to a third preset rule;
The third preset rule includes one of the following:
B121, when the target portion of the seventh target row in the first time domain resource allocation table is subjected to target feedback time offset (herein, the target portion is indicated by DCI and the target feedback time offset is scheduled), and the target time domain resource allocation record does not have a corresponding candidate transmission opportunity, determining that the target time domain resource allocation record corresponds to the first candidate transmission opportunity;
the target portion is any portion obtained by splitting a PDSCH subset of the seventh target row, and corresponds to one PDSCH subset, and the target time domain resource allocation record is any time domain resource allocation record corresponding to the target portion.
That is, when a portion of a certain row in the higher layer configuration or predetermined TDRA Table, a certain K1 in the higher layer configuration or predetermined K1 Set is applied, and no corresponding Occasion exists, this portion (PDSCH corresponding to each SLIV in) corresponds to Occasion (i.e., the first candidate transmission opportunity).
Optionally, the first candidate transmission opportunity includes one of:
b1211, the seventh target row applies a first preset candidate transmission opportunity of the at least one candidate transmission opportunity determined by the target feedback time offset;
that is, in this case, the row applies the designation Occasion of one or more Occasion of this K1 determination.
For example, the first preset candidate transmission opportunity is the first Occasion or the last Occasion.
B1212, a second preset candidate transmission opportunity of the at least one candidate transmission opportunity corresponding to the target feedback time offset;
that is, in this case, the K1 corresponds to the designation Occasion of one or more Occasion.
For example, the first preset candidate transmission opportunity is the first Occasion or the last Occasion.
B122, when the target part of the seventh target row in the first time domain resource allocation table is applied with the additional feedback time offset and the target time domain resource allocation record does not have a corresponding candidate transmission opportunity, determining that the target time domain resource allocation record corresponds to the second candidate transmission opportunity;
that is, when a portion of a certain row in the higher-layer configuration or predetermined TDRA Table, a certain additional K1 is applied (this additional K1 is not any K1 in the higher-layer configuration or predetermined K1 Set, and is derived based on a certain K1 (hereinafter referred to as reference K1) selected from the higher-layer configuration or predetermined K1 Set, and a certain/certain predefined rule), and no corresponding Occasion exists, all of this portion (PDSCH corresponding to each SLIV in) corresponds to Occasion 2 (i.e., second candidate transmission opportunity).
Optionally, the second candidate transmission opportunity includes one of:
B1221, the seventh target line applying a third preset candidate transmission opportunity of the at least one candidate transmission opportunity determined by the preset feedback time offset;
it should be noted that this case refers to the designation Occasion of one or more Occasion, such as the first Occasion or last Occasion, determined by the row using the preset feedback time offset (i.e., preset K1).
B1222, presetting a fourth preset candidate transmission opportunity in at least one candidate transmission opportunity corresponding to the feedback time offset;
It should be noted that, this case refers to the assignment Occasion, such as the first Occasion or the last Occasion, of the one or more Occasion corresponding to the preset K1.
B1223, fifth preset candidate transmission opportunity;
it should be noted that, the fifth preset candidate transmission opportunity may be a single Occasion that is additionally set, and this Occasion may be attached before (the head) or after (the tail) the set of Occasion determined in step 201.
Optionally, the preset feedback time offset includes one of the following:
B21, reference feedback time offset;
it should be noted that, alternatively, the reference feedback time offset may be one of a higher layer configuration or a predetermined set of K1, and the additional K1 (additional feedback time offset) is derived by applying the reference feedback time offset and some predefined rule(s).
B22, the feedback time offset with the smallest interval with the additional feedback time offset in the target feedback time offset set;
B23, the target feedback time offset sets are based on the feedback time offset increment direction and the feedback time offset with the smallest interval with the additional feedback time offset;
b24, the target feedback time offset sets are respectively provided with one feedback time offset with the smallest interval with the additional feedback time offset according to the decreasing direction of the feedback time offset.
Optionally, it should be further noted that, when the target time domain resource allocation record includes a plurality of candidate transmission opportunities, the determining manner of the candidate transmission opportunities of the first time domain resource allocation record includes one of the following:
c11, determining a candidate transmission opportunity corresponding to a target time domain resource allocation record which is positioned behind the first time domain resource allocation record and closest to the first time domain resource allocation record, and taking the candidate transmission opportunity as the candidate transmission opportunity of the first time domain resource allocation record;
Wherein, being located after and closest to the first time domain resource allocation record means that the start time is located at or after the end time of the first time domain resource allocation record (i.e. the current SLIV) and the earliest start time is the target SLIV.
C12, determining a candidate transmission opportunity corresponding to a target time domain resource allocation record which is positioned before the first time domain resource allocation record and closest to the first time domain resource allocation record, and taking the candidate transmission opportunity as the candidate transmission opportunity of the first time domain resource allocation record;
Wherein being located before and closest to the first time domain resource allocation record refers to the end time being located at or before the start time of the first time domain resource allocation record (i.e. current SLIV) and ending at the latest target SLIV.
C13, determining a candidate transmission opportunity corresponding to a target time domain resource allocation record closest to the first time domain resource allocation record as a candidate transmission opportunity of the first time domain resource allocation record;
The most recent target time domain resource allocation record can be understood here as: (assuming that there is no target SLIV that overlaps with the current SLIV in the time domain), taking the difference between the start time of the target SLIV and the end time of the current SLIV for the target SLIV whose start time is at or after the end time of the current SLIV; for the target SLIV whose end time is at or before the start time of the current SLIV, taking the difference between the start time of the current SLIV and the end time of the target SLIV; the target SLIV with the smallest difference is taken as the nearest target SLIV.
It should be noted that some Occasion corresponds to an additional time-domain feedback record based on the correspondence determined in B11 and B12 above, in addition to the corresponding SLIV subset determined in the codebook construction process (e.g., some K1 in the higher-layer configuration or the predetermined K1 Set, some Occasion corresponds to some SLIV subset).
2. For implementation II
Alternatively, the implementation procedure that can be adopted by this implementation manner is:
Step 20221, determining a candidate transmission opportunity corresponding to each first time domain feedback record according to a fourth preset rule, where the first time domain feedback record corresponds to a first PDSCH;
Step 20222, determining a first PDSCH corresponding to each candidate transmission opportunity according to the candidate transmission opportunities corresponding to the feedback record of each first time domain, so as to obtain a correspondence between each candidate transmission opportunity and the first PDSCH;
it should be noted that, the number of candidate transmission opportunities obtained by the final determination may be 0,1 or more (two or more) corresponding to the first PDSCH.
Step 20223, setting a value of a HARQ-ACK bit corresponding to each candidate transmission opportunity in the HARQ-ACK codebook according to the correspondence between each candidate transmission opportunity and the first PDSCH;
Note that, for Occasion where one or more corresponding scheduled PDSCH exist, the corresponding HARQ-ACK bit is set based on the result of Time domain bundling decoding the one or more corresponding scheduled PDSCH, and the other HARQ-ACK bits corresponding to Occasion are set (or maintained) to the default NACK.
It should be noted that, the fourth preset rule includes at least one of the following:
d11, determining a first time domain feedback record corresponding to each first PDSCH and a candidate transmission opportunity corresponding to the first time domain feedback record;
alternatively, in this case, it may be implemented in the following manner:
determining a first time domain feedback record corresponding to each first PDSCH, and determining a candidate transmission opportunity corresponding to the first time domain feedback record according to a fifth preset condition and a sixth preset condition (in an alternative implementation, the fifth preset condition and the sixth preset condition are required to be met simultaneously);
Wherein the fifth preset condition is: the reference equivalent feedback time offset corresponding to the first time domain feedback record is equal to the reference feedback time offset corresponding to the target candidate transmission opportunity;
the sixth preset condition includes at least one of the following:
D111, the subset of the reference time domain resource allocation records corresponding to the target candidate transmission opportunity includes the reference time domain resource allocation record corresponding to the first time domain feedback record;
D112, the start symbol of the reference time domain resource allocation record corresponding to the first time domain feedback record is no later than the earliest end symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
D113, the subset of the reference time domain resource allocation records corresponding to the target candidate transmission opportunity meets a seventh preset condition;
The seventh preset condition is: the starting symbol of the reference time domain resource allocation record corresponding to the first time domain feedback record is not earlier than the earliest starting symbol of the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity, and the ending symbol of the reference time domain resource allocation record corresponding to the first time domain feedback record is not later than the latest ending symbol of the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity.
Optionally, when there are a plurality of target candidate transmission opportunities that meet the seventh preset condition, the determining manner of the candidate transmission opportunities corresponding to the first time domain feedback record may further include:
selecting one of the target candidate transmission opportunities according to an eighth preset condition;
wherein the eighth preset condition includes one of:
E11, selecting one with the smallest sequence number of the target candidate transmission opportunity;
E12, selecting the earliest starting symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
e13, selecting the earliest ending symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity;
and E14, selecting the earliest ending symbol in the reference time domain resource allocation record subset corresponding to the target candidate transmission opportunity.
It should be noted that, the implementation of D11 is basically similar to the implementation of B11 described above, and the implementation of D11 may be obtained by replacing the time domain resource allocation record (i.e. SLIV) in B11 with the scheduled PDSCH in D11, so as to determine the corresponding relationship between the scheduled PDSCH and Occasion.
In this case, since the PDSCH scheduling is directly considered, the time domain erasure method is not required to be considered.
D12, respectively corresponding the first PDSCH which does not correspond to the candidate transmission opportunities to the target candidate transmission opportunities;
alternatively, one implementation that may be employed in this case is:
for a first PDSCH not corresponding to a candidate transmission opportunity, acquiring a candidate transmission opportunity corresponding to a target PDSCH which belongs to the same DCI schedule as the first PDSCH and has a corresponding candidate transmission opportunity as the candidate transmission opportunity corresponding to the first PDSCH.
Note that, for a certain scheduled PDSCH (hereinafter, referred to as a current scheduled PDSCH) that does not correspond to any Occasion, occasion corresponding to a scheduled PDSCH (hereinafter, referred to as a target scheduled PDSCH) that is scheduled by the same DCI (and that corresponds to HARQ-ACK on the same PUCCH is fed back) and that corresponds to Occasion is taken as a target Occasion. It can be understood that the currently scheduled PDSCH, as well as the target scheduled PDSCH, corresponds to the same row in the higher layer configuration or predetermined TDRA Table.
In either the HARQ-ACK feedback scheme one or the HARQ-ACK feedback scheme two, each first PDSCH that does not correspond to a candidate transmission opportunity needs to be respectively associated with a target candidate transmission opportunity in this manner.
It should be noted that, in the first HARQ-ACK feedback scheme, the target candidate transmission opportunity of each first PDSCH that does not correspond to the candidate transmission opportunity may be obtained, but in the second HARQ-ACK feedback scheme, when a certain line in the higher layer configuration or predetermined TDRA Table only partially schedules PDSCH to feed back the corresponding HARQ-ACK on a certain semi-static codebook, the constructed semi-static codebook may not have Occasion corresponding to the portion of the scheduled PDSCH in the line (because the new line corresponding to the portion of the scheduled PDSCH applies a certain K1 in the higher layer configuration or predetermined K1 Set, but any of the scheduled PDSCH in the portion does not have corresponding Occasion, or the new line applies a certain additional K1, and the additional K1 does not have corresponding Occasion). Thus, in this case, in the case where the candidate transmission opportunity corresponding to the first PDSCH of the candidate transmission opportunity exists in the row where the first time domain resource allocation record is not acquired, it should further include:
Acquiring a target candidate transmission opportunity corresponding to the first PDSCH according to a ninth preset rule;
The ninth preset rule includes one of the following:
d121, when a target portion of an eighth target row in the first time domain resource allocation table applies a target feedback time offset in a target feedback time offset set and a target PDSCH does not have a corresponding candidate transmission opportunity, determining that the target PDSCH corresponds to a third candidate transmission opportunity;
The target portion is any portion obtained by splitting a PDSCH subset of the eighth target row, and corresponds to one PDSCH subset, and the target PDSCH corresponds to any time domain resource allocation record of the target portion.
That is, when a part of a certain row in the higher layer configuration or the predetermined TDRA Table, a certain K1 in the higher layer configuration or the predetermined K1 Set is applied, and no corresponding Occasion exists, the part (PDSCH corresponding to each SLIV) corresponds to the third candidate transmission opportunity.
Optionally, the third candidate transmission opportunity includes one of:
D1211, the eighth target row applies a sixth preset candidate transmission opportunity of the at least one candidate transmission opportunity determined by the target feedback time offset;
that is, in this case, the row applies the designation Occasion of one or more Occasion of this K1 determination.
For example, the sixth preset candidate transmission opportunity is the first Occasion or the last Occasion.
D1212, a seventh preset candidate transmission opportunity in the at least one candidate transmission opportunity corresponding to the target feedback time offset;
that is, in this case, the K1 corresponds to the designation Occasion of one or more Occasion.
For example, the seventh preset candidate transmission opportunity is the first Occasion or the last Occasion.
D122, when the target portion of the eighth target row in the first time domain resource allocation table applies an additional feedback time offset and the target PDSCH does not have a corresponding candidate transmission opportunity, determining that the target PDSCH corresponds to the fourth candidate transmission opportunity;
That is, when a portion of a certain row in the higher-layer configuration or predetermined TDRA Table, a certain additional K1 is applied (this additional K1 is not any K1 in the higher-layer configuration or predetermined K1 Set, and is derived based on a certain K1 (hereinafter referred to as reference K1) selected from the higher-layer configuration or predetermined K1 Set, and a certain/certain predefined rule), and no corresponding Occasion exists, all of this portion (PDSCH corresponding to each SLIV in this portion) corresponds to the fourth candidate transmission opportunity.
Optionally, the fourth candidate transmission opportunity includes one of:
D1221, the eighth target line applying an eighth preset candidate transmission opportunity of the at least one candidate transmission opportunity determined by the preset feedback time offset;
it should be noted that this case refers to the designation Occasion of one or more Occasion, such as the first Occasion or last Occasion, determined by the row using the preset feedback time offset (i.e., preset K1).
D1222, presetting a ninth preset candidate transmission opportunity in the at least one candidate transmission opportunity corresponding to the preset feedback time offset;
It should be noted that, this case refers to the assignment Occasion, such as the first Occasion or the last Occasion, of the one or more Occasion corresponding to the preset K1.
D1223, tenth preset candidate transmission opportunity;
it should be noted that, the tenth preset candidate transmission opportunity may be a single Occasion that is additionally set, and this Occasion may be attached before (the head) or after (the tail) the set of Occasion determined in step 201.
Optionally, the preset feedback time offset includes one of the following:
D21, reference feedback time offset;
it should be noted that, alternatively, the reference feedback time offset may be one of a higher layer configuration or a predetermined set of K1, and the additional K1 (additional feedback time offset) is derived by applying the reference feedback time offset and some predefined rule(s).
D22, the feedback time offset with the smallest interval with the additional feedback time offset in the target feedback time offset set;
D23, the target feedback time offset sets are based on the feedback time offset increment direction and the feedback time offset with the smallest interval with the additional feedback time offset;
D24, the target feedback time offset sets are according to feedback time offset decreasing direction and the minimum one feedback time offset of interval of the additional feedback time offset. Optionally, when there are multiple target PDSCH, the determining manner of the candidate transmission opportunity corresponding to the first PDSCH includes one of the following:
d31, determining a candidate transmission opportunity corresponding to a target PDSCH which is positioned before the first PDSCH and closest to the first PDSCH as a candidate transmission opportunity corresponding to the first PDSCH;
D32, determining a candidate transmission opportunity corresponding to a target PDSCH which is positioned behind the first PDSCH and closest to the first PDSCH, as a candidate transmission opportunity corresponding to the first PDSCH;
and D33, determining a candidate transmission opportunity corresponding to a target PDSCH nearest to the first PDSCH as the candidate transmission opportunity corresponding to the first PDSCH.
That is, when there are a plurality of target PDSCH, a single target PDSCH may be selected from the above-described B12 by selecting a single target SLIV from a plurality of targets SLIV (the target SLIV in B12 may be replaced by the target PDSCH here), and its corresponding Occasion may be taken as the target Occasion.
The difference between the two implementations is mainly that:
Implementation-from the perspective of Occasion, the actual corresponding PDSCH set is determined for each Occasion. That is, first, the Occasion is not discriminated based on whether or not the PDSCH is actually scheduled or not based on whether or not a certain PDSCH CANDIDATE is actually scheduled; then, for a PDSCH set corresponding to one Occasion, it is determined whether each PDSCH CANDIDATE corresponds to a scheduled PDSCH.
In the second implementation manner, from the aspect of scheduling PDSCH, all scheduled PDSCH to be fed back is divided into corresponding Occasion. At this point, some Occasion correspond to one to multiple scheduled PDSCH, where a partially scheduled PDSCH (0, 1 or more) corresponds to a subset of SLIV corresponding to this Occasion and a partially scheduled PDSCH (0, 1 or more) corresponds to this Occasion based on predefined rules; some Occasion, because they do not correspond to any scheduled PDSCH, do not contemplate any extension on the basis of the corresponding SLIV subset.
In summary, the main implementation manner of the embodiment of the application is as follows: when Multi-PDSCH scheduling is supported and Time Domain Bundling is applied for HARQ-ACK semi-static codebook, the following method may be employed: the corresponding semi-static codebook construction flow of the existing SINGLE PDSCH scheduling is used as much as possible, and decoding information corresponding to all the scheduled PDSCH is carried in the constructed codebook (if necessary) in a Time Domain Bundling mode.
For example, in fig. 3, it is assumed that the UE configures only a single serving cell, only a single K1 value is included in the higher layer configuration or the predetermined K1 Set, only two rows are included in the higher layer configuration or the predetermined TDRA Table, one row corresponds to a single SLIV ((0-13) representing the occupied symbol index range), and the other row corresponds to three SLIV ((2-7) + (8-13) + (0-10), spanning two downlink slots).
For step 201, assuming that time domain erasure mode 1 is used, and that neither the high layer configuration nor the two rows in predetermined TDRA Table collide with Semi-static UL Symbol based on the transmission position of the Semi-static codebook and the (single) K1 value in the high layer configuration or the predetermined K1 Set, then both may be reserved in equivalent TDRA Table.
Assuming that each row of equivalents TDRA Table only retains the upper level configuration or the last SLIV of the corresponding row in the predetermined TDRA Table, then equivalent TDRA Table comprises two rows, one comprising a single SLIV (0-13) and the other comprising a single SLIV (0-10). Based on Pruning/Grouping operations in the existing semi-static codebook construction flow, there is overlap between two SLIV corresponding to the two rows, and thus a single SLIV subset. Thus, the semi-static codebook corresponds to only a single Occasion, i.e., only a single Occasion is included in the Occasion set to which the semi-static codebook corresponds.
For step 202, assume that setting 2 is adopted, and PDSCH represented by the diagonal filled box in fig. 3 is actually scheduled (i.e., the higher layer configuration or predetermined TDRA Table rows corresponding to three SLIV are indicated in the scheduling DCI, so that the corresponding three PDSCH are actually scheduled). Based on D11, it is known that the last scheduled PDSCH of the three scheduled PDSCH corresponds to the aforementioned unique Occasion (assuming SLIV subset condition 1 is applied), and the other two scheduled PDSCH does not correspond to any Occasion. Based on D12, the other two scheduled PDSCH may target Occasion corresponding to the last scheduled PDSCH Occasion. Based on step 20216, the HARQ-ACK bits corresponding to the single Occasion corresponding to the semi-static codebook are set based on the Time domain bundling output of the decoding results of the three scheduled PDSCH. Assuming that the configuration employs single codeword transmission and that no CBG (code block group) based transmission is configured, this Occasion corresponds to 1 bit. Assume that the decoding results of the three scheduled PDSCH are in order: 0,1 (0 denotes NACK,1 denotes ACK); the 1 bit is set to 0 (NACK).
It should be further noted that, for the first HARQ-ACK feedback mode, the setting of the HARQ-ACK codebook is performed in the corresponding mode in the above description, and for the second HARQ-ACK feedback mode, optionally, the implementation of a12 in step 2011 may be used (i.e., this mode corresponds to step 2011 which is an extension of the first HARQ-ACK feedback mode), and step 202 uses the same implementation as the first HARQ-ACK feedback mode; alternatively, it may adopt the implementation manner of a11 in step 2011 (i.e. the same implementation manner as HARQ-ACK feedback manner one is adopted), in one case, in step 202, if there is a time domain resource allocation record in which the corresponding candidate transmission opportunity cannot be obtained in one of the implementation manners, obtaining the correspondence between the candidate transmission opportunity and the time domain resource allocation record by using B121 and B122 (i.e. this manner corresponds to step 202 which is an extension of HARQ-ACK feedback manner one); in another case, when the second implementation mode is used in step 202, if there is a time domain resource allocation record in which the corresponding candidate transmission opportunity cannot be obtained, the candidate transmission opportunity and the PDSCH corresponding to the HARQ-ACK need to be fed back in the HARQ-ACK codebook are obtained by using D121 and D122 (i.e., this mode corresponds to step 202 which is an extension of the first HARQ-ACK feedback mode).
It should also be noted that, optionally, the terminal sets an HARQ-ACK codebook, and the terminal needs to send the HARQ-ACK codebook to the network side device at a corresponding feedback position. After receiving the HARQ-ACK codebook, the network side device parses the HARQ-ACK codebook according to the same understanding as that of the terminal side, and obtains a feedback result of the terminal for each PDSCH.
It should be noted that, when Multi-PDSCH scheduling is supported in the embodiment of the present application, under the condition that a single DCI can schedule at least two PDSCHs, determining a bit sequence of an HARQ-ACK codebook according to a target feedback time offset set and an equivalent time domain resource allocation table corresponding to one time domain resource allocation record for each row, and setting a bit value of the HARQ-ACK codebook based on the scheduled PDSCH to be fed back; specific feasible solutions are provided for the HARQ-ACK semi-static codebook application Time Domain Bundling, so that the semi-static codebook construction flow is simplified, and the feedback load is reduced.
It should be noted that, in the codebook setting method provided in the embodiment of the present application, the execution body may be a codebook setting device, or a control module in the codebook setting device for executing the codebook setting method. In the embodiment of the present application, a codebook setting device executes a codebook setting method as an example, and the codebook setting device provided in the embodiment of the present application is described.
