The content involved in the embodiment of the present application is introduced below.

1. SPS (semi-persistent scheduling) PDSCH (physical downlink shared channel) HARQ-ACK feedback mechanism in NR (new air interface);

In NR Rel (version)-15, SPS (Semi-persistent Scheduling, Semi-persistent Scheduling) PDSCH transmission is introduced: after activation of downlink SPS transmission, PDSCH transmission is initiated periodically, and these PDSCH transmissions have no corresponding downlink control information DCI indication , transfer based on a predefined method) transfer. For the downlink SPS transmission of NR Rel-15, the network side guarantees that in a certain serving cell group configured for the terminal UE, only a single serving cell is configured with the semi-persistent scheduling configuration item of SPS-Config, and the corresponding SPS PDSCH transmission interval The minimum is 10 milliseconds. For the SPS PDSCH transmission that ends in slot n, the UE feeds back the HARQ-ACK corresponding to this SPS PDSCH transmission in slot n+k, where k is determined by the PDSCH-to-HARQ-timing in the DCI that activates this SPS PDSCH transmission (timing)-indicator (indicator) indicator field to determine.

In Rel-16 URLLC (Ultra-Reliable Low-Latency Communication), in order to shorten the transmission delay of service data as much as possible, the network side can configure multiple SPS-Config configuration items that take effect at the same time for a single UE (a certain part of a single serving cell The bandwidth BWP can be configured up to 8 items at the same time), and the corresponding SPS PDSCH transmission interval can be shortened to a minimum of a single time slot. For a certain SPS-Config configured for UE, after activation, the timing relationship between SPS PDSCH transmission and its corresponding HARQ-ACK feedback is exactly the same as NR Rel-15.

2. SPS HARQ-ACK collision and recovery of time division duplex TDD system in URLLC;

In URLLC Rel-16, the downlink SPS transmission is enhanced. A single UE can support multiple SPS-Configs at the same time, and each SPS-Config can support a smaller period (to a single time slot). Since each SPS-Config can only use a single HARQ-ACK feedback timing after activation, indicated by the latest activation or reactivation DCI, in the TDD system, there will be some SPS PDSCH Occasion (opportunity) after activation or reactivation of SPS The physical uplink control channel PUCCH transmission where the corresponding HARQ-ACK is located (or the PUCCH resource carrying the SPS HARQ-ACK) and at least one Semi-static DL/SSB/CORESET#0 symbol (that is, a semi-static downlink symbol, or a synchronization signal block symbol or control resource set 0 symbol) conflicts lead to the failure of transmission, resulting in the discarding of SPS HARQ-ACK; when the SPS transmission period is shorter, or the proportion of Semi-static DL/SSB/CORESET#0 symbols in the frame structure is larger , the greater the probability of this conflict, which seriously affects the transmission performance of SPS PDSCH (in the case that the network side cannot receive SPS HARQ-ACK, it can only perform blind scheduling for the corresponding SPSPDSCH, thereby reducing system efficiency, or giving up the corresponding SPS PDSCH, resulting in a large residual packet error rate).

In this regard, the SPS HARQ-ACK deferral (delay) scheme is currently introduced to solve this problem.

For the SPS HARQ-ACK deferral scheme, a brief introduction is as follows:

For a certain SPS HARQ-ACK bit, if it is based on the corresponding SPS PDSCH and HARQ-ACK timing (that is, HARQ-ACK timing, that is, the HARQ-ACK feedback timing relationship, which can be understood as K1 indicated in the corresponding activated DCI), in Feedback within uplink UL slot/sub-slot (ie slot or sub-slot) n, then UL slot/sub-slot n can be called the initial (initial) slot/sub-slot corresponding to this SPS HARQ-ACK bit. If the SPS HARQ-ACK bit in the initial slot/sub-slot cannot be combined with other uplink control information UCI (referring to other UCIs except SPS HARQ-ACK, including DG (dynamic scheduling) HARQ-ACK or scheduling request SR or Channel State Information (CSI) is multiplexed, and (after considering multiplexing with other SPS HARQ-ACKs) the determined SPS HARQ-ACK PUCCH resources (ie PUCCH SPS-PUCCH-AN-List-r16 or n1PUCCH-AN parameter configuration HARQ-ACK PUCCH resources, where PUCCH SPS-PUCCH-AN-List-r16 is a SPS HARQ-ACK PUCCH resource list, n1PUCCH-AN is used to indicate a single SPSHARQ-ACK PUCCH resource, "AN" means ACK/NACK) and Semi - static DL/SSB/CORESET#0 symbol conflicts, when the SPS Config corresponding to the SPS HARQ-ACK bit is configured with deferral, the deferral operation is triggered, and the next available PUCCH resource or available PUSCH resource needs to be found for it (the time depends on After that, it is currently assumed to be in other slots/sub-slots after the initial slot/sub-slot).

For one or more SPS HARQ-ACK bits that trigger the deferral operation (the initial slot/sub-slot corresponding to each SPS HARQ-ACK bit may be different; hereinafter, these SPS HARQ-ACK bits can also be considered to be in the deferral process) , to search for available PUCCH resources or available PUSCH resources slot by slot/sub-slot in each slot/sub-slot after the initial slot/sub-slot. When in a candidate slot/sub-slot (Candidateslot/sub-slot), SPS HARQ-ACK bits (including SPS HARQ-ACK bits in the deferral process) can be combined with other UCIs (referring to SPS HARQ-ACK except other UCI, including DG HARQ-ACK or SR or CSI) for multiplexing, or (when it cannot be multiplexed with other UCIs) determined SPS HARQ-ACK PUCCH resources (ie PUCCH SPS-PUCCH-AN-List-r16 or There is no conflict between the HARQ-ACK PUCCH resource configured by the n1PUCCH-AN parameter) and the Semi-static DL/SSB/CORESET#0 symbol, then this Candidate slot/sub-slot is considered to be (all) SPS in the deferral process The HARQ-ACK bit finds the available PUCCH resource or the available PUSCH resource. At this time, the deferral is stopped, and this Candidate slot/sub-slot is also used as the target (target) slot/sub-slot corresponding to the Deferred SPSHARQ-ACK bits in the deferral process. .

For each SPS Config, you can independently configure whether to enable deferral, and when deferral is configured, you can further configure the maximum deferral value (maximum delay value). For a certain SPS HARQ-ACK bit, if it triggers a deferral operation, and no available PUCCH resource or available PUSCH resource has been found in the Candidate slot/sub-slot that is away from the initial slot/sub-slot by maximum deferralvalue, the SPS HARQ-ACK bits will be discarded due to timeout.

3. HARQ-ACK retransmission mechanism in URLLC;

For the deleted HARQ-ACK in URLLC Rel-17 (for example, because of Rel-16intra-UEprioritization (UE internal priority processing), the low-priority HARQ-ACK is Dropped (discarded), or because of Rel-16cancellation indication (delete indication) is dropped Deleted HARQ-ACK), currently two retransmission mechanisms are introduced at the same time: Enhanced (enhanced) Type (type)-3HARQ-ACK codebook (codebook) and One-shot triggering ofHARQ-ACK re-transmission (one-time trigger HARQ -ACK retransmission).

1. About the Enhanced Type-3 HARQ-ACK codebook:

For the Enhanced Type-3 HARQ-ACK codebook, the main idea is to follow the construction idea of Rel-16Type-3codebook (construct the codebook from the perspective of HARQ process, adopt CC (carrier or cell)-HARQ process-TB (transport block, Transport Block) to determine the HARQ-ACK bit sequence corresponding to the codebook; consider all downlink HARQ processes configured for each cell in all cells configured for the UE), but only the HARQ-ACK corresponding to the CC or HARQ process subset can be reported , so that the reporting of the HARQ-ACK corresponding to a certain subset can be triggered as needed, so that a smaller codebook size can be used to match the HARQ-ACK information that needs to be retransmitted. Considering that the subsets required in different situations are different, the network can pre-configure a codebook or state list, and each codebook or state in the list corresponds to a (different) subset (corresponding to a single Enhanced Type-3HARQ-ACK codebook), the network can select the most matching subset according to needs, and trigger the corresponding codebook or state. At present, the maximum number of Enhanced Type-3 HARQ-ACK codebooks that UE can support at the same time is 8.

2. About One-shot triggering of HARQ-ACK re-transmission:

For One-shot triggering of HARQ-ACK re-transmission, the main idea is to trigger the retransmission of the deleted HARQ-ACK codebook in a certain UL slot/sub-slot, and trigger DCI to indicate a new ULslot/sub-slot The PUCCH resources in the network are used to retransmit the deleted HARQ-ACK codebook intact. Each DCI can only trigger the retransmission of a single HARQ-ACK codebook. Only a single HARQ-ACK codebook can be triggered to be retransmitted in a single new UL slot/sub-slot. When the initial transmission HARQ-ACK (corresponding to the same physical layer priority) still exists in the new UL slot/sub-slot, the retransmission HARQ-ACK codebook is concatenated after the HARQ-ACK codebook corresponding to the initial transmission HARQ-ACK.

The information transmission method provided by the embodiment of the present application will be described in detail below through some embodiments and application scenarios with reference to the accompanying drawings.

The first time unit can be understood as a feedback time unit, and the second time unit can be understood as a trigger time unit. "The first time unit is the same as the second time unit" at least includes: the time unit is the same, but the occupied positions are offset; for example, the time units are the same, and the occupied symbols are offset.

Wherein, the determining the feedback codebook of the first Semi-Persistent Scheduling Hybrid Automatic Repeat Request Response SPSHARQ-ACK according to the one-time trigger DCI includes: the terminal determines the information of the second time unit according to the one-time trigger DCI; the terminal Determine the first SPS HARQ-ACK according to the information of the second time unit; the terminal constructs the feedback codebook based on the first SPS HARQ-ACK.

The information transmission method provided by the embodiment of the present application is described below with an example, and the time unit is Slot/sub-slot as an example.

In view of the above technical problems, and considering that the feedback of SPS HARQ-ACK is actively triggered based on One-shot triggering of re-transmission, the network side can control the feedback of SPSHARQ-ACK more flexibly and dynamically, and improve The reliability of SPS HARQ-ACK feedback ensures the performance of SPS PDSCH transmission; and for the combination or interoperability of One-shot triggering of re-transmission and SPS HARQ-ACK deferral, there is currently no relevant solution, so it is impossible to combine the two Effective combination to achieve flexible, controllable and timely and reliable SPS HARQ-ACK feedback; therefore, the embodiment of the present application provides an information transmission method, which mainly involves: based on One-shottriggering of re-transmission can trigger specified Slot/sub- The SPS HARQ-ACK bit (corresponding to the above-mentioned second SPS HARQ-ACK) existing in the slot (subsequently referred to as triggering Slot/sub-slot, corresponding to the above-mentioned second time unit), in the indicated Slot/sub-slot ( Subsequent calls it feedback Slot/sub-slot, corresponding to the above-mentioned first time unit) for feedback. The downlink assignment (DL assignment) DCI used to trigger HARQ-ACK feedback here is referred to as One-shot triggering DCI hereinafter. Among them: the following mainly considers that the target or operation object of One-shot triggering DCI is (Deferred) SPS HARQ-ACK bit; about triggering the retransmission of other codebooks and piggybacking the operation of transmitting DeferredSPS HARQ-ACK bit, in the following embodiment one to describe.

Specifically, the solution provided in the embodiment of this application may include at least one of the following operations:

Operation 1: Trigger the determination of Slot/sub-slot;

At present, the main consideration is to trigger the Slot/sub-slot as the feedback Slot/sub-slot or the Slot/sub-slot before it (that is, the feedback Slot/sub-slot). Optionally, triggering the Slot/sub-slot may also be the Slot/sub-slot after the feedback Slot/sub-slot, which is not limited here.

When determining to trigger a Slot/sub-slot, any of the following methods can be used:

Method 1: Trigger the Slot/sub-slot as a predefined Slot/sub-slot (corresponding to the above predefined time unit);

At this time, One-shot triggering DCI does not need to explicitly indicate to trigger Slot/sub-slot. One-shottriggering DCI can either schedule PDSCH or not schedule PDSCH (for example, set the frequency domain resource allocation FDRA indication field to a special value to indicate that no PDSCH is scheduled).

Either of the following methods can be further used:

Method 1-1: Trigger Slot/sub-slot as feedback Slot/sub-slot;

The purpose or application scenario can be: when there is no dynamically scheduled DG HARQ-ACK (that is, the HARQ-ACK corresponding to DCI) in the feedback Slot/sub-slot, the PUCCH resources used in the feedback Slot/sub-slot can be dynamically adjusted (Before it is adjusted, only SPS HARQ-ACK PUCCH resources or SR PUCCH resources or CSI PUCCH resources configured semi-statically can be used, which may be dropped due to multiplexing with SR or CSI but actually unable to transmit, or because SPS HARQ - ACK PUCCH resource conflicts with Invalid symbol (illegal symbol, that is, the aforementioned Semi-static DL/SSB/CORESET#0 symbol) and further delays Defer, or is discarded because it reaches the upper limit corresponding to the maximum deferral value Drop), to ensure (Deferred ) Timely and reliable transmission of SPS HARQ-ACK.

Method 1-2: Triggering the Slot/sub-slot is the Slot/sub-slot where the One-shot triggering DCI is received;

The purpose or application scenario may be: trigger feedback of SPS HARQ-ACK bits existing in the specified Slot/sub-slot, or further include SPS HARQ-ACK bits associated with these SPS HARQ-ACK bits (see "HARQ-ACK bits" below) ACK item 2") to avoid being dropped or further Defer, so as to ensure the timely and reliable transmission of SPS HARQ-ACK.

The Slot/sub-slot where the One-shot triggering DCI is received can be understood as: the UL slot/sub-slot where the end moment of the physical downlink control channel PDCCH carrying the One-shot triggering DCI is located, or, the same as the one-shot triggering The last UL slot/sub-slot in the UL slot/sub-slot where the PDCCH of DCI overlaps.

Method 1-3: Trigger the Slot/sub-slot to be a Slot/sub-slot offset by M Slots/sub-slots relative to the reference Slot/sub-slot (corresponding to the above reference time unit);

Purpose or application scenario: consistent with method 1-2.

The reference Slot/sub-slot can be: Feedback Slot/sub-slot, or the Slot/sub-slot where One-shot triggeringDCI is received.

When the reference Slot/sub-slot is the feedback Slot/sub-slot, M can be understood as the number of Slot/sub-slots offset to the elapsed time direction (that is, to the left on the time axis), that is, to trigger the Slot/sub-slot The slot is the feedback Slot/sub-slot (at this time, it can be considered that M=0), or the Slot/sub-slot that is offset by M Slot/sub-slot before the feedback Slot/sub-slot; when referring to the Slot/sub When -slot is the Slot/sub-slot where One-shot triggering DCI is received, M can be understood as the time direction toward the past (that is, to the left on the time axis) or the time direction to the future (that is, to the right on the time axis) ) The number of Slot/sub-slot offset. It can be further stipulated that the corresponding offset amount is positive when offset in a certain direction, and the corresponding offset amount is negative when offset in the opposite direction. M can be an integer, and can be 0, a positive integer or a negative integer based on the aforementioned direction specification. M can be determined based on a predefined rule, or configured by high-layer signaling.

For example, when referring to Slot/sub-slot as the Slot/sub-slot where One-shot triggering DCI is received, M can be understood as the corresponding first moment to meet the DCI decoding delay relative to the end moment of One-shot triggering DCI The requested first (or earliest) UL Slot/sub-slot (assumed to be the intended time unit), relative to the Slot/sub-slot of the Slot/sub-slot where the One-shot triggering DCI is received (assumed to be the reference time unit) Slot offset, that is, M is the time unit offset of the intended time unit relative to the reference time unit, where the first moment corresponding to the UL Slot/sub-slot is the starting moment of the UL Slot/sub-slot, or the UL The starting time of the PUCCH resource expected to be used in the Slot/sub-slot; triggering the Slot/sub-slot can be understood as the first (or earliest) UL Slot/sub-slot that satisfies the DCI decoding delay.

Method 2: triggering Slot/sub-slot is the Slot/sub-slot indicated by One-shot triggering DCI;

The purpose or application scenario can be: basically the same as the above methods 1-1~1-3, the main difference is that the Slot/sub-slot can be triggered by the One-shot triggering DCI dynamic instruction, which is more flexible, but additional instructions need to be introduced overhead.

At this time, One-shot triggering DCI needs to explicitly indicate to trigger Slot/sub-slot:

(1) When it is necessary (as far as possible) to keep the DCI size (size, which can be understood as the corresponding number of bits) unchanged, the One-shot triggering DCI cannot schedule the PDSCH. At this time, some unused instructions in the One-shot triggering DCI can be used A bit of a field (for example, an indication field used when scheduling a PDSCH) indicates a trigger Slot/sub-slot.

(2) When the indication bit can be newly introduced into the One-shot triggering DCI, there is no restriction on whether the One-shot triggering DCI schedules the PDSCH (for example, based on the value of the FDRA indication field to determine whether the PDSCH is actually scheduled), a new one is introduced at this time Indicates field to indicate triggering Slot/sub-slot.

When indicating to trigger Slot/sub-slot, it can indicate the absolute time position of triggering Slot/sub-slot, such as SFN (System Frame Number, System Frame Number) and the Slot/sub-slot index in the wireless frame, or indicate Offset N relative to the reference Slot/sub-slot.

The reference Slot/sub-slot can be: Feedback Slot/sub-slot, or the Slot/sub-slot where One-shot triggeringDCI is received.

When the reference Slot/sub-slot is the feedback Slot/sub-slot, N can be understood as the number of Slot/sub-slots shifted toward the elapsed time direction (that is, to the left on the time axis); when referring to the Slot/sub- When the slot is the Slot/sub-slot where the One-shottriggering DCI is received, N can be understood as the direction of the past time (that is, to the left on the time axis) or to the future time direction (that is, to the right on the time axis). Number of Slots/sub-slots to shift. It can be further stipulated that the corresponding offset amount is positive when offset in a certain direction, and the corresponding offset amount is negative when offset in the opposite direction. N can be an integer, and can be 0, a positive integer or a negative integer based on the aforementioned direction specification. N may be determined based on a predefined rule, or configured by high-layer signaling.

When applying any of the above methods, it is assumed that there must be SPS HARQ-ACK bits in the triggering Slot/sub-slot (including the initial Initial SPS HARQ-ACK, and/or, Deferred SPS HARQ-ACK; regardless of the triggering Slot/sub- The slot has been dropped by SPS HARQ-ACK before), and the triggered SPS HARQ-ACK bit is considered to have obtained the transmission opportunity, and there is no need to trigger or continue Defer. In other words, the UE does not expect to trigger any SPS HARQ-ACK bits in the Slot/sub-slot; after receiving the One-shot triggering DCI, the UE does not need to Defer and One-shot triggering DCI after feedback of the Slot/sub-slot The corresponding (or triggered by) SPS HARQ-ACK bit (UE can drop this information, no need to maintain it).

Operation 2: Trigger the determination of SPS HARQ-ACK and the construction of the codebook;

In the feedback Slot/sub-slot, when the HARQ-ACK codebook is organized based on One-shot triggering of re-transmission, the organized codebook includes at least one of the following items (or at least HARQ-ACK item 1, optionally including Other one or more):

HARQ-ACK item 1: Trigger the SPS HARQ-ACK bit existing in the Slot/sub-slot, which may include at least one of the following:

HARQ-ACK subitem 1-1: all Initial SPS HARQ-ACK;

The Initial SPS HARQ-ACK here refers to the feedback in the triggering Slot/sub-slot based on the corresponding SPS PDSCH and HARQ-ACK timing (that is, corresponding to the K1 indicated in the activated DCI, corresponding to the above-mentioned HARQ-ACK feedback timing relationship). SPS HARQ-ACK, the SPS Config corresponding to a certain bit may be configured with deferral or may not be configured with deferral.

Optionally, when the triggering Slot/sub-slot is not a feedback Slot/sub-slot, the following one or more items in the Initial SPSHARQ-ACK can be removed, and only the transmission of the remaining Initial SPS HARQ-ACK (if it exists) is considered :

(1) The corresponding SPS Config is not configured with deferral Initial SPS HARQ-ACK (assuming that the reliability requirements for these SPSHARQ-ACKs are low);

(2) The corresponding SPS Config is configured with deferral, but the feedback Slot/sub-slot has exceeded the maximum deferral value configured by the corresponding SPS Config relative to the trigger Slot/sub-slot (as the Initial slot/sub-slot) Initial SPS HARQ- ACK (assuming that these SPS HARQ-ACKs have timed out and are less useful);

(3) The corresponding SPS Config is configured with deferral, but the Initial SPS HARQ-ACK corresponding to the Target slot/sub-slot has been determined before the Slot/sub-slot is fed back (assuming that these SPS HARQ-ACKs have already obtained transmission opportunities).

HARQ-ACK subitem 1-2: all Deferred SPS HARQ-ACK;

The Deferred SPS HARQ-ACK here refers to the SPS HARQ-ACK that has triggered or started the deferral process (in the Slot/sub-slot earlier than the Slot/sub-slot that triggered the Slot/sub-slot), and any bit in it must be configured with a certain item Corresponding to SPS Config of deferral.

Optionally, when the triggering Slot/sub-slot is not a feedback Slot/sub-slot, the following Deferred SPS HARQ-ACK in the Deferred SPSHARQ-ACK can be removed, and only the remaining Deferred SPS HARQ-ACK (if it exists) is considered transmission:

(1) Feedback Slot/sub-slot relative to the corresponding Initial slot/sub-slot, Deferred SPS HARQ-ACK that has exceeded the maximum deferral value configured by the corresponding SPS Config (assuming that these SPSHARQ-ACKs have timed out and are less useful) ;

(2) The DeferredSPS HARQ-ACK corresponding to the Target slot/sub-slot has been determined before the Slot/sub-slot is fed back (assuming that these SPS HARQ-ACKs have already obtained transmission opportunities).

HARQ-ACK item 2: From the next Slot/sub-slot that triggers the Slot/sub-slot until the Slot/sub-slot is fed back, the SPS HARQ-ACK that needs to be transmitted;

The SPS HARQ-ACK that needs to be transmitted here can include starting from the next Slot/sub-slot that triggers the Slot/sub-slot until the feedback Slot/sub-slot, each Slot/sub-slot (assumed to be the reference Slot/sub-slot SPS HARQ-ACK bits existing in slot). Among them, referring to the determination of the SPS HARQ-ACK bits existing in the Slot/sub-slot, you can refer to the corresponding description in "HARQ-ACK subitem 1-1", that is, refer to the (all) InitialSPS HARQ corresponding to the Slot/sub-slot -ACK, just replace the "trigger Slot/sub-slot" in the description with "reference Slot/sub-slot"; note that it is currently assumed that the organization's codebook already includes "HARQ-ACK item 1", so for the reference Slot /sub-slot no longer needs to consider Deferred SPS HARQ-ACK (to avoid repeated consideration), only need to consider the newly generated Initial SPS HARQ-ACK.

Only when the triggering Slot/sub-slot is not a feedback Slot/sub-slot, the "SPS HARQ-ACK that needs to be transmitted" mentioned here is considered.

Optionally, only the SPS HARQ-ACK bits existing in L-1 Slots/sub-slots starting from the next Slot/sub-slot that triggers the Slot/sub-slot can be considered, that is, when it is assumed that the organized codebook When "HARQ-ACK item 1" has been included, consider the SPS HARQ-ACK bits existing in a total of L Slot/sub-slots starting from triggering Slot/sub-slot (when starting from triggering Slot/sub-slot until feedback When the number of Slot/sub-slot is still less than L, the actual number shall prevail). L is determined based on a predefined rule, or is configured by high-level signaling.

Optionally, for the above-mentioned several Slots/sub-slots starting from the next Slot/sub-slot that triggered the Slot/sub-slot (L-1 Slots/sub-slots, or until the feedback Slot/sub-slot All Slots/sub-slots), only consider the SPS HARQ-ACK bits corresponding to the reference SPS Config and/or reference priority in the SPS HARQ-ACK bits existing in each Slot/sub-slot, here refer to SPS Config (or reference Priority) is any SPS Config (or physical layer priority) corresponding to the SPS HARQ-ACK bit existing in the trigger Slot/sub-slot. For example, assuming that the SPS HARQ-ACK bits in the triggered Slot/sub-slot correspond to two items of SPS Config, for these "several Slots/sub-slots", only the corresponding two bits in each Slot/sub-slot are considered. The SPS HARQ-ACK bit of any SPSConfig in the item SPS Config.

HARQ-ACK sub-item 3-1: When the One-shot triggering DCI schedules the PDSCH, the HARQ-ACK corresponding to the scheduled PDSCH;

HARQ-ACK sub-item 3-2: feedback Initial SPS HARQ-ACK corresponding to Slot/sub-slot;

When the trigger Slot/sub-slot is the feedback Slot/sub-slot, the Initial SPS HARQ-ACK here is the Initial SPS HARQ-ACK corresponding to "HARQ-ACK subitem 1-1".

HARQ-ACK subitem 3-3: Other DCI indicates the HARQ-ACK fed back in the feedback Slot/sub-slot;

Wherein, other DCI includes any DCI that needs to be fed back corresponding to the HARQ-ACK, such as downlink scheduling DCI, DCI indicating SPS release (release), and the like.

When organizing the codebook, the initial transmission of HARQ-ACK (if it exists; corresponding to "HARQ-ACK item 3") can construct a separate HARQ-ACK subcodebook (assumed to be the first subcodebook) based on the Rel-16 rule, Deferred SPS HARQ-ACK and/or Initial SPS HARQ-ACK of non-corresponding feedback Slot/sub-slot (if present; corresponding to "HARQ-ACK item 2" and/or "HARQ-ACK item 3"; excluding corresponding feedback Slot/sub-slot The Initial SPS HARQ-ACK of the sub-slot) can construct a separate HARQ-ACK sub-codebook based on the Rel-16 rule (assumed to be the second sub-codebook; it can be unified as the Deferred SPS HARQ-ACK in the SPS HARQ-ACKdeferral) Construct a HARQ-ACK (sub)codebook). When both sub-codebooks exist, the first sub-codebook and the second sub-codebook can be concatenated to obtain the actual transmitted HARQ-ACK codebook, for example, the second sub-codebook can be concatenated on the first sub-codebook after the codebook.

Operation 3: Feedback determination of PUCCH resources;

When there are A One-shot triggering DCIs (A>0; when there is more than one, based on the current Agreement, it is required to indicate the same HARQ-ACK codebook, or be extended to indicate the same HARQ-ACK reporting range), B When other DCI (needs to feed back the corresponding HARQ-ACK; B≥0) indicates the same feedback Slot/sub-slot, for the determination of the PRI (PUCCH resource indication) corresponding to the PUCCH resource used in the feedback Slot/sub-slot, you can Do any of the following:

Mode 1: Always use the PRI indicated by the last DCI among all DCIs;

All the DCIs here refer to the above A+B DCIs. For the sequence of DCIs, the current rules can be used for sorting. For example, the sorting can be performed based on the starting time of the PDCCH monitoring occasion (Monitoring Occasion) in which the DCI is detected, and the corresponding DCI whose starting time of the PDCCH monitoring occasion is later is deemed to be received later. When the corresponding DCIs are received in multiple PDCCH monitoring opportunities corresponding to the same starting moment, the sequence relationship between these DCIs can be further determined based on the cell index, for example, the DCI with a larger corresponding cell index is considered to be received later .

Method 2: Always use the PRI indicated by the (last) One-shot triggering DCI;

Generally, the PRI indicated by the last One-shot triggering DCI can be used. Optionally, it is required that the PRIs indicated in A One-shot triggering DCIs are consistent, and at this time, the PRI indicated in any one-shot triggering DCI can be used.

Mode 3: It is required that the PRIs indicated by all DCIs are consistent.

In this case, the PRI indicated in any DCI can be used.

Operation 4: Processing of physical layer priority;

In general, the above operations can be understood as: the physical layer priority indicated by One-shot triggering DCI, and at the same time indicates the feedback priority (that is, the physical layer of the HARQ-ACK codebook transmitted in the feedback Slot/sub-slot Priority, or, the physical layer priority corresponding to the PUCCH that carries this HARQ-ACK codebook), and the trigger priority, that is, the physical layer priority corresponding to the SPS HARQ-ACK bit that triggers the transmission (that is, only triggers the indication in the DCI The SPS HARQ-ACK bit corresponding to the physical layer priority; the corresponding situation of the current scheme). Among them, the physical layer priority corresponding to a certain SPS HARQ-ACK can be determined by its corresponding SPS Config (specifically, the physical layer priority can be included in the high-level configuration parameters of SPS Config).

Optionally, the above operations can also be extended to cross physical layer priorities (that is, the trigger priority is not required to be the same as the feedback priority, or in other words, the physical layer priority corresponding to the SPS HARQ-ACK bit that does not require trigger transmission must be The SPS HARQ-ACK triggering scenario is the same as the physical layer priority indicated by One-shot triggering DCI).

Specifically, it is assumed that the feedback priority can be determined based on the indication in the One-shot triggering DCI, or a predefined rule (for example, when there is no explicit indication in the DCI, the corresponding default physical layer priority, such as low priority), can be determined Level (that is, the physical layer priority of the HARQ-ACK codebook transmitted in the feedback Slot/sub-slot, or the physical layer priority corresponding to the PUCCH carrying the HARQ-ACK codebook), specifically, any of the following priorities can be adopted The level restriction scheme determines the first SPS HARQ-ACK in the foregoing schemes (that is, the following schemes correspond to the above priority restriction conditions):

Scheme 1: SPS HARQ-ACK in the above operations requires a corresponding feedback priority (that is, it is required to correspond to the first priority above);

For example, in "Operation 2: Trigger SPS HARQ-ACK Determination and Codebook Construction", only SPS HARQ-ACK corresponding to the feedback priority is considered.

Scheme 2: SPS HARQ-ACK in the above operations can correspond to any priority;

The "corresponding to any priority" mentioned here can be understood as not paying attention to the physical layer priority corresponding to SPS HARQ-ACK, and processing it uniformly, for example, including SPS HARQ-ACK corresponding to high priority and low priority into the scope of processing.

At this point, the above operations can be directly followed.

Optionally, considering that it is generally believed that when high-priority HARQ-ACK and low-priority HARQ-ACK are multiplexed in the same PUCCH, the two are coded separately, and the following adjustments can be introduced: "Operation 2: Trigger SPS HARQ-ACK ACK Determination and Codebook Construction", when organizing codebooks, the corresponding HARQ-ACK sub-codebooks are constructed respectively based on the priority of the physical layer, for example, the corresponding HARQ-ACK sub-codebook is constructed based on the corresponding high priority HARQ-ACK (if it exists). High-priority HARQ-ACK sub-codebooks, based on the corresponding low-priority HARQ-ACK (if it exists), construct corresponding low-priority HARQ-ACK sub-codebooks, HARQ-ACK sub-codebooks with different physical layer priorities Encoded independently.

Scheme 3: The physical layer priority requirement corresponding to the SPS HARQ-ACK in the above operations is not lower than the feedback priority (that is, the physical layer priority requirement corresponding to the first SPS HARQ-ACK above is higher than or equal to the first priority);

The "corresponding physical layer priority is not lower than the feedback priority" mentioned here can be understood as when triggering the feedback of SPS HARQ-ACK corresponding to a certain physical layer priority, it is necessary to ensure that the higher priority SPS HARQ-ACK ACK also gave feedback.

When "the corresponding physical layer priority is not lower than the feedback priority" is applied or after, when the HARQ-ACK of the operation only corresponds to a single physical layer priority, if this single physical layer priority is the feedback priority, it can be used The operation corresponding to solution 1; if the single physical layer priority is other than the feedback priority, the operation corresponding to solution 2 can be followed.

When the "corresponding physical layer priority is not lower than the feedback priority" is applied or after, when the HARQ-ACK of the operation corresponds to a physical layer priority greater than one (that is, corresponding to multiple physical layer priorities), the scheme 2 can be followed corresponding operation.

The above solutions provided in the embodiments of the present application are illustrated below with examples.

For example, in Figure 4 (one-shot triggering of re-transmission can be shown to obtain (Deferred) SPS HARQ-ACK), the SPS HARQ-ACK corresponding to the SPS PDSCH transmitted in Slot 1 is based on SPSPDSCH and HACK-ACK timing, it is expected Transmit in Slot 5, that is, use Slot 5 as the initial slot. However, the SPS HARQ-ACK PUCCH resources determined in Slot 5 cannot be transmitted due to conflicts with semi-static downlink symbols. Assuming that the SPS Config corresponding to this SPS PDSCH is configured to enable or apply the SPS HARQ-ACK deferral mechanism, then when the solution of the present invention is not applied, based on the SPS HARQ-ACK deferral mechanism, the SPSHARQ-ACK corresponding to this SPS PDSCH is expected to be delayed to Slot 8 internal transmission. After introducing the solution of the present invention, based on the realization of the network side equipment, a one-time trigger DCI can be sent to the terminal in Slot 6 (Slot 6 is used as the trigger Slot, or the second time unit) to trigger the terminal to feedback Deferred SPS in Slot 7 HARQ-ACK (that is, the SPS HARQ-ACK corresponding to the above SPS PDSCH). After the terminal feeds back the SPS HARQ-ACK corresponding to the above SPS PDSCH based on the one-time trigger DCI indication in Slot 7, it does not need to continue to perform deferral operations on the SPS HARQ-ACK corresponding to the above SPS PDSCH.

Specifically, it is the PUCCH resource occupied by the SPS HARQ-ACK corresponding to the SPS PDSCH transmitted in Slot 1 in Figure 4 in its corresponding initial slot, and the deferral is triggered because it conflicts with the Semi-static DL symbol, and the present invention is not introduced In the corresponding technical solution, based on the SPS HARQ-ACK deferral mechanism, it is expected to delay the transmission in slot 8, and through the corresponding technical solution of the present invention, it can be transmitted in slot 7, thereby shortening the feedback delay.

Among them, K1 in Figure 4 represents the offset between the time unit where the SPS PDSCH is received (such as a time slot or sub-slot) and the time unit where the corresponding SPS HARQ-ACK initial feedback opportunity is located, or K1 represents a one-time trigger The offset between the time unit where the DCI is received (such as a time slot or sub-slot) and the time unit where the triggered HARQ-ACK feedback is located, "D" means downlink, and "U" means uplink.

Embodiment 1: (DCI transmission) triggering retransmission of other codebooks and piggybacking transmission of Deferred SPS HARQ-ACK bits;

When there is at least one valid HARQ-ACK bit ( That is, when any of the following conditions (corresponding to the above-mentioned first condition) is met, one-shot triggering ofre-transmission can be used to trigger the retransmission of this HARQ-ACK codebook:

(1) Not SPS HARQ-ACK bits;

(2) It is the SPS HARQ-ACK bit, but the corresponding SPS Config (that is, the SPS configuration item) is not configured with deferral;

(3) For the SPS HARQ-ACK bit, the corresponding SPS Config is configured with deferral, but Defer is not triggered;

(4) For the SPS HARQ-ACK bit, the corresponding SPS Config configures deferral, triggers Defer, and determines Slot/sub-slot n (corresponding to the third time unit above) as Target slot/sub-slot (corresponding to target time units above).

The above HARQ-ACK codebook may not be actually transmitted due to related protocol mechanisms (such as SFI, intra-UE UCI multiplexing Intra-UE UCImultiplexing (or priority processing prioritization), cancellation indication Cancellation indication, etc.) is actually not transmitted, or actually has been transmitted , but the network side missed detection or wrong detection, etc. At this time, the network side can use One-shot triggering of re-transmission to trigger the retransmission of the HARQ-ACK codebook, corresponding to the above-mentioned one-shot trigger downlink control information DCI sent to the terminal.

It can be understood that when any valid HARQ-ACK bit in a HARQ-ACK codebook in a certain Slot/sub-slot (that is, excluding padding NACK) is an SPS HARQ-ACK bit and is triggered Defer or When Defer is continued, the HARQ-ACK codebook does not correspond to the regular Case applicable to One-shot triggering of re-transmission in this Slot/sub-slot (the regular Case here means that the HARQ-ACK codebook is in a certain The transmission opportunity was obtained in the Slot/sub-slot but was eventually deleted), but the transmission was delayed, so One-shot triggering of re-transmission cannot be used to trigger the retransmission of this HARQ-ACK codebook.

When one-shot triggering DCI triggers a certain HARQ-ACK codebook (that is, "other codebook", corresponding to the above-mentioned first HARQ-ACK codebook) to be reported in the feedback Slot/sub-slot, if the feedback Slot/sub - When there is at least one Deferred SPS HARQ-ACK bit that satisfies the physical layer priority condition (corresponding to the second condition above) in the slot, the triggered HARQ-ACK codebook can be used as a DG HARQ-ACK, and it is combined with this at least one Deferred SPS HARQ-ACK bit SPS HARQ-ACK bits perform HARQ-ACK multiplexing, and perform subsequent UCI multiplexing or prioritization operations as needed. In this solution, it may also be: the terminal transmits the triggered HARQ-ACK codebook, and the at least one delayed SPS HARQ-ACK bit continues to perform a delayed operation.

The above-mentioned physical layer priority condition can be any of the following (refer to the foregoing description for similar feedback priorities):

(1) Corresponding feedback priority (corresponding to the second priority above);

(2) Corresponding to any priority;

(3) The corresponding physical layer priority is not lower than the feedback priority.

For the above situation, when the organization feeds back the codebook in the Slot/sub-slot:

(1) The triggered HARQ-ACK codebook can be used as the first sub-codebook. When the initial transmission HARQ-ACK still exists in the feedback Slot/sub-slot, the triggered HARQ-ACK codebook can be concatenated after the codebook corresponding to the initial transmission HARQ-ACK, and output the first sub-codebook.

(2) The above at least one Deferred SPS HARQ-ACK bit can construct a second sub-codebook based on a predefined rule.

After that, the first sub-codebook and the second sub-codebook are concatenated to obtain the codebook in the feedback Slot/sub-slot, for example, the second sub-codebook is concatenated after the first sub-codebook.

From the above, the scheme provided by the embodiment of this application provides a feasible implementation scheme for the combination or interoperation of One-shot triggering of re-transmission and SPS HARQ-ACK deferral, so that the SPS HARQ-ACK deferral can be controlled more flexibly and dynamically.
