Technical Field

Background

With the development of communication technology, enhancements are made to downlink Semi-persistent scheduling (Semi-PERSISTENT SCHEDULING, SPS) transmission, a single terminal may support multiple SPS configurations (SPS-Config) simultaneously, and each SPS configuration may support a smaller period. Since each SPS configuration can only use a single hybrid automatic repeat request acknowledgement (Hybrid automatic repeat request acknowledgement, HARQ-ACK) feedback timing after activation, it is indicated by the most recent activation or reactivation downlink control information (Downlink Control Information, DCI). In a time division multiplexing (Time Division Duplex, TDD) system, after SPS is activated or re-activated, there is a physical uplink channel where a part of SPS physical downlink shared channel (Physical Downlink SHARED CHANNEL, PDSCH) opportunities (Occasion) corresponding to HARQ-ACKs collide with at least one downlink symbol, so that transmission cannot be performed. For this reason, the introduction of HARQ-ACK information delayed transmission to reduce the impact on SPS PDSCH transmission performance is discussed. However, there is no explicit scheme in the discussion for the operational behavior restrictions of the HARQ process for which the HARQ-ACK information corresponds.

For ease of understanding, some of the following descriptions are directed to embodiments of the present application:

1. SPS PDSCH HARQ-ACK feedback mechanism in NR.

For downlink SPS transmission, the network side device ensures that, in a certain service cell group configured for the terminal, only a single service cell is configured with a semi-persistent scheduling configuration (SPS-Config) configuration item at most, and the corresponding SPS PDSCH transmission interval is 10 ms at minimum. For SPS PDSCH transmission ending in slot n, the terminal feeds back HARQ-ACK corresponding to this SPS PDSCH transmission in slot n+k, where k is determined by the PDSCH-to-HARQ-timing-indicator indication field in the DCI activating this SPS PDSCH transmission.

In order to shorten the transmission delay of service data, the network side device may configure multiple SPS-Config configuration items that are valid simultaneously for a single terminal, and the corresponding SPS PDSCH transmission interval may be shortened to a minimum of a single slot. Wherein a certain bandwidth Part (BWP) of a single serving cell can be configured with 8 items at the same time at most.

2. SPS PDSCH HARQ-ACK collision and recovery for TDD systems in Ultra-Reliable and Low Latency Communications, URLLC communications.

The downlink SPS transmission is enhanced, a single terminal can support multiple SPS-Config at the same time, and each SPS-Config can support a smaller period. Since each SPS-Config can only use a single HARQ-ACK feedback timing after activation, it is indicated by the latest activated or reactivated DCI. In a TDD system, after SPS is activated or re-activated, there is a collision between PUCCH transmission where HARQ-ACK corresponding to part SPS PDSCH Occasion is located and at least one downlink symbol, so that transmission cannot be performed, and SPS HARQ-ACK is discarded. When the proportion of the downlink symbol configuration in the frame structure is large, the probability of such collision is large, thereby seriously affecting the SPS PDSCH transmission performance.

The transmission processing method provided by the embodiment of the application is described in detail below by means of some embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a transmission processing method according to an embodiment of the present application, as shown in fig. 2, including the following steps:

Step 201, in the case that the first HARQ process is occupied by the first semi-persistent scheduling physical downlink shared channel SPS PDSCH, the terminal determines an operation behavior associated with the first HARQ process:

Wherein the operational behavior comprises at least one of:

operation behavior 1, before a first time corresponding to the first HARQ process, performing first PDSCH transmission without using the first HARQ process, where the first PDSCH transmission is a dynamically scheduled PDSCH or a second SPS PDSCH;

an operation behavior 2, discarding first HARQ-ACK information based on a first preset rule, where the first HARQ-ACK information corresponds to the first SPS PDSCH;

And an operation act 3, wherein, under the condition that the first HARQ process corresponds to M valid second HARQ-ACK information, the target HARQ-ACK information which needs to be fed back by the first HARQ process is determined based on a second preset rule, the target HARQ-ACK information is one of the M valid second HARQ-ACK information, and M is a positive integer.

In the embodiment of the present application, for the first SPS PDSCH transmission, a first HARQ process may be occupied, and the terminal may perform SPS PDSCH reception and decoding based on the HARQ process and feedback corresponding HARQ-ACK information, which may also be referred to as SPS HARQ-ACK.

Optionally, PDSCH transmissions are in one-to-one correspondence with HARQ-ACK information, and a HARQ process may correspond to one or more valid HARQ-ACK information, where the valid second HARQ-ACK information refers to HARQ-ACK information that is not discarded and that needs or may continue to be fed back. The first HARQ process may be referred to as an SPS HARQ process, and the first HARQ-ACK information may be referred to as SPS HARQ-ACK information. Alternatively, in some embodiments, the first PDSCH transmission described above may be understood as a new dynamically scheduled PDSCH transmission or a new SPS PDSCH transmission, or as other PDSCH transmissions that subsequently occupy the first HARQ process.

For operation 1, it may be understood that further occupation of the first HARQ process is limited, for example, in the case that the first HARQ-ACK information corresponding to the first HARQ process is delayed to be sent, it is guaranteed that the network side device dynamically schedules PDSCH transmission or second SPS PDSCH transmission by using the first HARQ process after receiving the HARQ-ACK information corresponding to the SPS HARQ process delayed (Deferred) as much as possible. Alternatively, in case that it is determined that a delay occurs based on the delay rule (DEFERRING RULES), the first HARQ-ACK information that is delayed to be transmitted may be understood as delayed SPS HARQ-ACK (DEFERRED SPS HARQ-ACK) information.

When the operation behavior 1 is adopted, the terminal does not need to consider that the first HARQ process is configured or scheduled for the first PDSCH transmission before the first time, so that implementation of the terminal can be simplified. In addition, the delayed HARQ-ACK information can be used for retransmission scheduling judgment and wireless link self-adaption, and the use efficiency of wireless resources can be improved.

It should be noted that, in some embodiments, the operation behavior 1 may be understood as: the terminal does not expect to receive the first PDSCH corresponding to the first HARQ process until the HARQ-ACK transmission of the SPS PDSCH corresponding to the first HARQ process ends. In some embodiments, it may also be understood that the terminal does not desire to receive the first PDSCH corresponding to the first HARQ process until the first time is reached.

As shown in fig. 3, in some embodiments, if feedback of HARQ-ACK information corresponding to a first HARQ process occupied by the SPS PDSCH collides with downlink symbols, the HARQ-ACK information is delayed for transmission in a next uplink transmission time unit. The network side device transmits the first PDSCH for the first HARQ process after receiving the delayed HARQ-ACK information, e.g., dynamically scheduling PDSCH.

For operation 2, it can be understood that the terminal decides whether to discard the first HARQ-ACK information based on the first preset rule. It should be understood that discarding the first HARQ-ACK information may be understood as discarding the first HARQ-ACK information transmitted at the initial SPS HARQ-ACK feedback time corresponding to the SPS PDSCH transmission, or discarding the first HARQ-ACK information transmitted with delay, where discarding may be understood as discarding the transmission. Optionally, after determining to discard the first HARQ-ACK information based on the first preset rule, the terminal does not consider transmission or retransmission of the first HARQ-ACK information any more.

When operational behaviour 2 is employed, no additional scheduling restrictions need to be introduced for the first HARQ process. Specifically, after the initial SPS HARQ-ACK feedback time corresponding to the SPS PDSCH transmission of a certain SPS HARQ process, the terminal may receive the dynamic scheduling PDSCH transmission or the SPS PDSCH transmission of the SPS HARQ process based on DCI of the network side device or configuration information of SPS Config (configuration), that is, the starting time of the dynamic scheduling PDSCH transmission or the SPS PDSCH transmission is located after the initial SPS HARQ-ACK feedback time.

For operation behavior 3, neither the additional scheduling constraint nor the first HARQ-ACK information of the discard delay is considered. This can be understood as: for a certain SPS HARQ process, only the scheduling restriction corresponding to the initial SPS HARQ-ACK feedback time corresponding to the corresponding SPS PDSCH transmission needs to be complied with. It should be understood that, when the network side device receives the target HARQ-ACK information, it needs to determine PDSCH transmission corresponding to the target HARQ-ACK information based on the second preset rule. That is, in the case that the first HARQ process corresponds to M valid second HARQ-ACK information, the network side device determines, based on a second preset rule, target HARQ-ACK information actually fed back by the first HARQ process.

It should be noted that, in some embodiments, the above-mentioned operation behaviors may include operation behavior 1 and operation behavior 2 at the same time, where both the additional scheduling constraint and the first HARQ-ACK information of the discard delay are considered. For example, if the first HARQ-ACK information corresponding to the first HARQ process is not yet transmitted at the first time, and the terminal needs to receive the first PDSCH transmission using the first HARQ process after the first time, the terminal may determine whether the first HARQ-ACK information is discarded based on the first preset rule in the operation behavior 2, and execute the corresponding discarding behavior when determining to discard.

In the embodiment of the application, under the condition that a first HARQ process is occupied by a first semi-persistent scheduling physical downlink shared channel SPSPS PDSCH, a terminal determines the operation behavior related to the first HARQ process: wherein the operational behavior comprises at least one of: before a first time corresponding to the first HARQ process, not using the first HARQ process to perform first PDSCH transmission, wherein the first PDSCH transmission is a dynamic scheduling PDSCH or a second SPS PDSCH; discarding first HARQ-ACK information based on a first preset rule, wherein the first HARQ-ACK information corresponds to the first SPS PDSCH; and under the condition that the first HARQ process corresponds to M effective second HARQ-ACK information, determining target HARQ-ACK information which needs to be fed back by the first HARQ process based on a second preset rule, wherein the target HARQ-ACK information is one of the M effective second HARQ-ACK information, and M is a positive integer. In the embodiment of the application, the operation behavior of the HARQ process occupied by the SPS PDSCH is clarified, so that the understanding consistency of the terminal and the network side equipment can be ensured, and the transmission reliability is improved.

Optionally, in some embodiments, the corresponding second time instant of the first PDSCH transmission is equal to or later than the first time instant.

In the embodiment of the present application, limiting further occupation of the first HARQ process may be understood as that the second time corresponding to the first PDSCH transmission is not earlier than the first time.

Optionally, the definition of the first time and the second time may be set according to actual needs, for example, in some embodiments, the second time corresponding to the first PDSCH transmission is any one of the following: and the time of the first PDSCH transmission, the time of the transmission of a physical downlink control channel (Physical Downlink Control Channel, PDCCH) corresponding to the first PDSCH transmission, and the time of the feedback of the HARQ-ACK corresponding to the first PDSCH transmission.

In the embodiment of the present application, the first PDSCH transmission may be a dynamic scheduling PDSCH or an SPS PDSCH. The time of the first PDSCH transmission may be a start time or an end time of the first PDSCH transmission, which may also be referred to as a start time.

The PDCCH transmission corresponding to the first PDSCH transmission may be understood as DCI carried by the PDCCH transmission is used to schedule the first PDSCH transmission, where the first PDSCH transmission may be understood as dynamically scheduling PDSCH. Alternatively, the time of PDCCH transmission may be understood as a start time or an end time of PDCCH transmission.

The time of the HARQ-ACK feedback corresponding to the first PDSCH transmission may be understood as a starting time or an ending time of an uplink channel where the HARQ-ACK feedback corresponding to the first PDSCH transmission is located, and the first PDSCH may be a dynamically scheduled PDSCH or an SPS PDSCH. The Uplink channel may be a PUCCH or a Physical Uplink SHARED CHANNEL, PUSCH channel.

Optionally, the first time is any one of the following: a transmission time of the first object; the time corresponding to the maximum delay (Maximum deferral); the time of the first object is earlier in the transmission time and the time corresponding to the maximum delay;

the first object is an uplink channel actually carrying the first HARQ-ACK information transmission.

In the embodiment of the present application, the uplink channel may be PUCCH or PUSCH. The actual carrying of the first HARQ-ACK information transmission may be understood as making an actual transmission in the target time unit based on a delay rule, or may be understood as an actual transmission triggered based on DCI. For example, in a triggered Type 3codebook (Type-3 codebook) or enhanced Type-3 codebook.

The time corresponding to the maximum delay may be understood as the start time or the end time of the time cell corresponding to the maximum delay. Wherein the maximum delay may be directly configured by the radio resource control (Radio Resource Control, RRC) or determined based on the K1 set (set) of higher layer configurations. It may refer to the maximum number of delay time units k1 _def with respect to the initial SPS HARQ-ACK feedback time unit (i.e., the time unit in which the initial feedback of SPS HARQ-ACK is located, also referred to as the initial time unit), or the maximum number of feedback offset time units k1 _eff＝k1+k1_def with respect to the time unit in which the SPS PDSCH ends. The time unit corresponding to the maximum delay may be determined based on the value of the maximum delay, the initial SPS HARQ-ACK feedback time unit, or the time unit at which the SPS PDSCH end time is located. In the embodiment of the application, the time unit can be a time slot (slot) or a sub-slot (sub-slot).

Note that, the first HARQ-ACK information corresponding to Deferred of the first HARQ process may trigger actual transmission based on DEFERRING RULES or DCI in a time unit before the time unit corresponding to the maximum delay, may trigger actual transmission based on DEFERRING RULES or DCI in the time unit corresponding to the maximum delay, or may not actually be transmitted even at the end time of the time slot/sub-time slot corresponding to the maximum delay. Assuming that the expected transmission time corresponding to the delayed first HARQ-ACK information corresponding to the first HARQ process is the latest end time of the time unit corresponding to the maximum delay, when the actual transmission is performed before the latest expected transmission time, the actual transmission time is determined, otherwise, the latest expected transmission time is determined. Therefore, in the embodiment of the present application, the first time may be set to be an earlier time of the first object and the time of the time unit corresponding to the maximum delay.

Optionally, in some embodiments, the first preset rule includes at least one of:

Discarding the first HARQ-ACK information if it is determined at a third time that the first HARQ process is scheduled or configured for the first PDSCH transmission;

discarding the first HARQ-ACK information at a fourth time.

Further, the first PDSCH transmission time and/or the HARQ-ACK feedback time corresponding to the first PDSCH transmission may be further defined. For example, in a case where it is determined at a third time that the first HARQ process is scheduled or configured for the first PDSCH transmission, discarding the first HARQ-ACK information includes:

discarding the first HARQ-ACK information if it is determined at a third time that the first HARQ process is scheduled or configured for the first PDSCH transmission and the first PDSCH transmission meets a preset condition;

wherein the preset conditions include at least one of:

the end time of the first PDSCH transmission is equal to or earlier than the first time;

the end time of the first PDSCH transmission is equal to or earlier than the end time of the initial feedback time unit of the first HARQ-ACK information;

The ending time of the first PDSCH transmission is equal to or earlier than a first preset time, wherein the first preset time is the starting time or the ending time of a first target channel, and the first target channel is an uplink channel for bearing the first HARQ-ACK information in an initial feedback time unit of the first HARQ-ACK information;

And the ending time of a second target channel is equal to or earlier than the first time, and the second target channel is an uplink channel where HARQ-ACK feedback corresponding to the first PDSCH transmission is located.

In the embodiments of the present application, equal to or earlier than is understood to be no later than. Alternatively, the second target channel may be PUCCH or PUSCH. The first HARQ process being scheduled for the first PDSCH transmission may be understood as the first HARQ process being scheduled for dynamically scheduling PDSCH transmission; the first HARQ process being configured for the first PDSCH transmission may be understood as the first HARQ process being configured for SPS PDSCH transmission.

Optionally, the third time instant comprises at least one of: the initial feedback moment of the first HARQ-ACK information; one moment in the delay procedure of the first HARQ-ACK information.

In the embodiment of the present application, it is assumed that, at the initial feedback time of the first HARQ-ACK information, when it has been determined that the first HARQ process has been scheduled for dynamic PDSCH transmission or configured for second SPS PDSCH transmission, the terminal does not need to delay the first HARQ-ACK information corresponding to the first HARQ process, and may directly discard the first HARQ-ACK information. As shown in fig. 4, the initial feedback time of the first HARQ-ACK information may be time 1, where time 1 may be understood as a starting time of an uplink channel for carrying the first HARQ-ACK information in the initial feedback time unit of the first HARQ-ACK information.

As shown in fig. 5, in the delay (refer) procedure, assuming that at time 2 it has been determined that the first HARQ process has been scheduled dynamic PDSCH transmission or has been configured with a second SPS PDSCH transmission, the terminal discards the DEFERRED SPS HARQ-ACK corresponding to the given SPS HARQ process and does not refer to this first HARQ-ACK any further.

For dynamic scheduling, the terminal may learn that the scheduled dynamic PDSCH transmission needs to occupy a given SPS HARQ process (i.e., the first HARQ process described above) by decoding DCI that schedules the dynamic PDSCH transmission. The decoding delay introduced into the scheduling DCI may be considered here so that the terminal and the network side device understand agreement as to whether the corresponding SPS HARQ-ACK for a given SPS HARQ process is discarded or not. The decoding delay can be reported based on the UE capability, or can be specified by a protocol or configured by network side equipment through signaling. For SPS PDSCH transmissions, the terminal may determine that a new SPS PDSCH exists to occupy a given SPS HARQ process based on semi-persistent configuration information, or based on semi-persistent configuration information and one or more SPS configs currently active. As shown in fig. 5, time 2 may be understood as a PDCCH end time carrying DCI for scheduling dynamic PDSCH transmission plus a corresponding time after DCI decoding delay.

Further, for dynamically scheduled PDSCH transmissions, the terminal need not delay the SPS HARQ-ACK for a given SPS HARQ process when it has been determined within an initial time unit that the SPS HARQ process has been scheduled for the dynamic PDSCH transmission, and the start/end time of the dynamic PDSCH transmission meets a predefined first condition, and/or the start/end time of the PUCCH/PUSCH transmission for which the HARQ-ACK feedback for the dynamic PDSCH transmission is located meets a predefined second condition.

The first condition may include one or more of the following:

the end time of dynamic scheduling PDSCH transmission is not later than the first time;

dynamically scheduling the end time of PDSCH transmission to be no later than the end time of the initial time unit;

the end time of dynamically scheduled PDSCH transmission is no later than the start/end time of PUCCH Resource (Resource) carrying SPS HARQ-ACK in the initial time unit.

The second condition may be: and the end time of the PUCCH/PUSCH transmission where the HARQ-ACK feedback corresponding to the dynamic scheduling PDSCH transmission is located is not later than the first time.

Further, for SPS PDSCH transmissions, when it has been determined within the initial time unit that a given SPS HARQ process has configured a second SPS PDSCH transmission, and the start/end time of this second SPS PDSCH transmission satisfies a predefined first condition, and/or the start/end time of the PUCCH/PUSCH transmission where the HARQ-ACK feedback corresponding to this second SPS PDSCH transmission is located satisfies a predefined second condition, the UE need not defer the SPS HARQ-ACK corresponding to this SPS HARQ process.

In the embodiment of the present application, after determining the delay of the HARQ-ACK information corresponding to the first HARQ process based on DEFERRING RULES, there will be a delay process, where the starting time of the delay process may be the initial feedback time of the first HARQ-ACK information.

Optionally, in some embodiments, the initial feedback time of the first HARQ-ACK information is any one of the following:

a starting time or an ending time of an initial feedback time unit of the first HARQ-ACK information;

And the first target channel is an uplink channel used for bearing the first HARQ-ACK information in an initial feedback time unit of the first HARQ-ACK information.

In the embodiment of the present application, the first target channel may be PUCCH or PUSCH.

Optionally, in some embodiments, the fourth time instant satisfies any one of the following:

The fourth time is a starting time of the first PDSCH transmission;

The fourth time is the end time of the first PDSCH transmission;

The fourth time is located after and has a first time offset from a starting time of the first PDSCH transmission;

the fourth time is located after the end time of the first PDSCH transmission and has a second time offset from the end time of the first PDSCH transmission;

the fourth time is the starting time of the time unit where the HARQ-ACK feedback corresponding to the first PDSCH transmission is located;

the fourth time is the end time of the time unit where the HARQ-ACK feedback corresponding to the first PDSCH transmission is located;

the fourth time is the starting time of an uplink channel carrying HARQ-ACK feedback corresponding to the first PDSCH transmission;

and the fourth time is the end time of an uplink channel carrying HARQ-ACK feedback corresponding to the first PDSCH transmission.

Assuming that in the refer procedure, at the start/end time of a scheduled dynamic PDSCH transmission or a configured new SPS PDSCH transmission of a given SPS HARQ process (i.e., the first HARQ process), or at the corresponding time after applying a predefined offset to the end time of this PDSCH transmission (time 3 as shown in fig. 6), the terminal discards the DEFERRED SPS HARQ-ACK corresponding to the given SPS HARQ process and does not make any further refer to this SPS HARQ-ACK.

For dynamic scheduling, it is considered here that the terminal has determined that a given SPS HARQ process needs to be occupied by a dynamic PDSCH transmission at the start/end time of the dynamic PDSCH transmission, or at the end time of the dynamic PDSCH transmission plus a time corresponding to a predefined time offset. The predefined time offset may be reported based on terminal capability, or may be specified by a protocol or configured by a network side device through signaling. For example, the predefined time offset may be determined based on N1 specified by the protocol, optionally also in combination with further reporting of terminal capabilities or network parameter configuration. Assuming that the terminal has, upon completion of decoding of the dynamic PDSCH transmission and preparation of HARQ-ACK information, it must have determined that a given SPS HARQ process needs to be occupied by this dynamic PDSCH transmission.

For SPS PDSCH transmissions, it is mainly considered that the network side device may skip (skip) certain SPS PDSCH transmission opportunities (SPS PDSCH occasion). If the terminal determines that a given SPS HARQ process needs to be occupied by a new SPS PDSCH that is actually transmitted at the start/end time of the second SPS PDSCH transmission (or SPS PDSCH occasion), or the end time of the second SPS PDSCH transmission (or SPS PDSCH occasion) plus a time corresponding to a predefined offset, the terminal discards the DEFERRED SPS HARQ-ACK corresponding to the given SPS HARQ process, otherwise if the terminal determines that the SPS PDSCH occasion is skip (i.e., the network side device does not actually transmit the new SPS PDSCH and occupies the given SPS HARQ process within the SPS PDSCH occasion), the terminal may not discard the DEFERRED SPS HARQ-ACK corresponding to the given SPS HARQ process (i.e., continue the transfer process).

Optionally, in the refer process, at the starting/ending time of the PUCCH/PUSCH transmission where the HARQ-ACK feedback corresponding to the scheduled dynamic PDSCH transmission or the configured new SPS PDSCH transmission of the given SPS HARQ process is located, the terminal discards DEFERRED SPS HARQ-ACK corresponding to the given SPS HARQ process, and does not make further refer to the SPS HARQ-ACK.

For dynamic scheduling, consider here that the terminal has been able to determine that DEFERRED SPS HARQ-ACK corresponding to a given SPS HARQ process is no longer valid when preparing for transmission or having transmitted HARQ-ACK feedback corresponding to dynamic PDSCH transmission, or that the HARQ-ACK information corresponding to this SPS HARQ process is covered by the HARQ-ACK information of the further scheduled dynamic PDSCH transmission, so that there is no need to retransmit DEFERRED SPS HARQ-ACK corresponding to this SPS HARQ process.

For SPS PDSCH transmissions, if the SPS HARQ-ACK corresponding to the second SPS PDSCH transmission already covers DEFERRED SPS HARQ-ACKs, then no retransmission of the DEFERRED SPS HARQ-ACK corresponding to this SPS HARQ process is needed. It should be appreciated that the PUCCH/PUSCH transmission where the HARQ-ACK feedback corresponding to the second SPS PDSCH transmission is located may also have a collision problem for the TDD system, and if a collision occurs, the DEFERRING RULES is applied for the HARQ-ACK corresponding to the second SPS PDSCH transmission.

Optionally, in some embodiments, the second preset rule includes any one of the following:

Determining HARQ-ACK information corresponding to the last second PDSCH transmission of the M second PDSCH transmissions in sequence according to the transmission sequence as the target HARQ-ACK information;

When N second PDSCH transmissions meet the requirement of a HARQ-ACK feedback time line (timeline), determining HARQ-ACK information corresponding to the last second PDSCH transmission of the N second PDSCH transmissions arranged according to the transmission sequence as the target HARQ-ACK information, wherein the M second PDSCH transmissions are in one-to-one correspondence with the M effective second HARQ-ACK information, and N is a positive integer smaller than or equal to M;

When any one of the second PDSCH transmissions does not meet the requirement of the HARQ-ACK feedback time line, determining that all bits corresponding to the target HARQ-ACK information are negative acknowledgements;

Wherein the second PDSCH transmission is a PDSCH transmission corresponding to the second HARQ-ACK information.

It should be appreciated that when none of the second PDSCH transmissions meets the HARQ-ACK feedback timeline requirement, it is understood that all of the second PDSCH transmissions do not meet the HARQ-ACK feedback timeline requirement. All bits corresponding to the target HARQ-ACK information are negative acknowledgements, which may be understood as each bit of the target HARQ-ACK information is a negative acknowledgement.

In the embodiment of the application, for a certain SPS HARQ process, only the scheduling limit corresponding to the initial SPS HARQ-ACK feedback moment corresponding to the corresponding SPS PDSCH transmission is required to be complied with, the scheduling limit of the operation behavior 1 is not required to be introduced, meanwhile, the decision rule considered in the operation behavior 2 is not required to be considered, and DEFERRED SPS HARQ-ACK is discarded when the rule is met.

At this time, when the codebook types (HARQ-ACK Codebook Type) other than Type-3 Codebook are adopted, there may be a case that HARQ-ACK information corresponding to multiple PDSCH transmissions corresponding to the same HARQ process is all contained in the same codebook for transmission based on the respective codebook construction flows, and at this time, the terminal may set HARQ-ACK bits corresponding to multiple PDSCH transmissions corresponding to the same HARQ process according to the HARQ-ACK information of each PDSCH transmission. After receiving the HARQ-ACK codebook fed back by the terminal, the network side device may process the HARQ-ACK information based on implementation, for example, for HARQ-ACK information corresponding to each of multiple PDSCH transmissions corresponding to the same HARQ process, only HARQ-ACK information corresponding to the later PDSCH transmission in the PDSCH transmissions is used, and HARQ-ACK information corresponding to the earlier PDSCH transmission is discarded. When Type-3 Codebook is adopted, a corresponding rule may be defined, and the UE determines, based on the rule, when there is more than one corresponding HARQ-ACK information for the same HARQ process (each corresponding to one PDSCH transmission corresponding to this HARQ process and still in a valid state, for example, for SPS HARQ-ACKs requiring Defer, still in a state that can be fed back, for scheduled dynamic PDSCH transmissions or configured SPS PDSCH transmissions, its corresponding HARQ-ACK is still in a state that can be fed back or fed back), which HARQ-ACK information to use for this HARQ process in constructing the codebook is determined specifically as follows:

mode 1: the HARQ-ACK information corresponding to the back or last PDSCH transmission is always adopted for the HARQ process;

mode 2: for this HARQ process, HARQ-ACK information corresponding to the latest PDSCH transmission that satisfies the HARQ-ACK feedback timing requirement is always adopted, and when none of the PDSCH transmissions is satisfied, the HARQ-ACK bit corresponding to this HARQ process may be set to NACK.

It should be understood that the terminal may indicate in the capability information whether to support one or more of the above operational actions and/or be configured by the network side device to employ some of the above operational actions. The operational behaviors herein include operational behavior 1, operational behavior 2, and operational behavior 3.

Optionally, a relationship between the physical layer priority (Priority indicator, which may be indicated in the DCI or configured by higher layer signaling, for PDSCH transmissions, indicating the priority of PUCCH transmissions carrying their corresponding HARQ-ACK feedback) of each corresponding HARQ-ACK feedback of a first SPS PDSCH transmission occupying the first HARQ process and the other PDSCH transmissions subsequently occupying the first HARQ process may also be considered, to determine whether to support some or more of the above operational behaviors.

For example, assume that the physical layer priority of HARQ-ACK feedback corresponding to SPS PDSCH transmission occupying the first HARQ process is the current priority, and the physical layer priority of HARQ-ACK feedback corresponding to first PDSCH transmission occupying the subsequent first HARQ process is the subsequent priority:

When the current priority and the subsequent priority are the same, for example, both correspond to the priority index 0 or the priority index 1, any one or more of the operation behavior 1, the operation behavior 2, and the operation behavior 3 may be supported, and/or one or more of the semi-static configuration at the network side or the dynamic indication of DCI may be used.

When the current priority is higher than the subsequent priority, for example, the current priority corresponds to priority index 1 and the subsequent priority corresponds to priority index 0, the performance of HARQ-ACK feedback with high priority needs to be guaranteed (i.e., the performance of HARQ-ACK feedback corresponding to SPS PDSCH transmission occupying the first HARQ process is guaranteed) preferentially, and only operation behavior 1 may be supported at this time. Optionally, operation behavior 3 may be further supported (at this point DEFERRED SPS HARQ-ACKs are not discarded when HARQ-ACK feedback is triggered without using Type-3 codebook). Optionally, the operational behavior supported by the determination of whether the first PDSCH transmission is a dynamically scheduled PDSCH transmission or an SPS PDSCH transmission may be distinguished. For example, when the first PDSCH transmission is a dynamically scheduled PDSCH transmission, since the network side device may dynamically determine the scheduling situation at this time, only operation behavior 1 may be supported, and optionally operation behavior 3 may be further supported; when the first PDSCH transmission is an SPS PDSCH transmission, the restriction may be relaxed, any one or more of operation behavior 1, operation behavior 2, and operation behavior 3 may be supported, and/or employed by network side semi-persistent configuration or DCI dynamic indication, because the case of an SPS PDSCH transmission belongs to semi-persistent determination.

When the current priority is lower than the subsequent priority, for example, the current priority corresponds to priority index 0 and the subsequent priority corresponds to priority index 1, the high priority HARQ-ACK feedback may preempt the low priority HARQ-ACK feedback. In this case, it is assumed that the first PDSCH transmission still needs to be guaranteed to be located after the initial SPS HARQ-ACK feedback time corresponding to the SPS PDSCH transmission occupying the first HARQ process, and only operation behavior 2 may be supported at this time. Optionally, operation behavior 3 may be further supported (no limitation is imposed on the type of codebook employed).
