Technical Field

Background

With the development of communication technology, an enhancement is made to downlink Semi-Persistent Scheduling (SPS) transmission, a single terminal may support multiple SPS configurations (SPS-Config) simultaneously, and each SPS configuration may support a smaller periodicity. Since each SPS configuration can only use a single Hybrid automatic repeat request acknowledgement (HARQ-ACK) feedback timing after activation, it is indicated by the latest activation or reactivation Downlink Control Information (DCI). In a Time Division Duplex (TDD) system, after an SPS is activated or reactivated, a Physical uplink Channel where HARQ-ACK corresponding to a partial SPS Physical Downlink Shared Channel (PDSCH) opportunity (occupancy) is located collides with at least one Downlink symbol, which results in failure to transmit.

Fig. 1 shows a block diagram of a wireless communication system to which embodiments of the present application are applicable.

Wherein, the terminal 11 may also be called as a terminal Device or a User Equipment (UE), the terminal 11 may be a Mobile phone, a Tablet Personal Computer (Tablet Personal Computer), a Laptop Computer (Laptop Computer) or a notebook Computer, a Personal Digital Assistant (PDA), a palmtop Computer, a netbook, a super-Mobile Personal Computer (UMPC), a Mobile Internet Device (MID), a Wearable Device (Wearable Device) or a vehicle-mounted Device (VUE), a pedestrian terminal (PUE), and other terminal side devices, the Wearable Device includes: smart watches, bracelets, earphones, glasses, and the like.

For convenience of understanding, some contents related to the embodiments of the present application are described below:

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

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

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

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

Enhanced for downlink SPS transmissions, a single terminal may support multiple SPS-configs simultaneously, and each SPS-Config may support a smaller periodicity. Since each SPS-Config can only use a single HARQ-ACK feedback timing after activation, indicated by the most recent activation or reactivation DCI. In the TDD system, after the SPS is activated or reactivated, the PUCCH transmission in which the HARQ-ACK corresponding to the partial SPS PDSCH Ocvasation is positioned collides with at least one downlink symbol to cause the transmission to be unavailable, thereby causing the SPS HARQ-ACK to be 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 embodiments of the present application is described in detail below with reference to the accompanying drawings by using some embodiments and application scenarios thereof.

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

step 201, under the condition that a first HARQ process is occupied by a first half persistent scheduling physical downlink shared channel (SPS PDSCH), a 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, not using the first HARQ process to perform a first PDSCH transmission, where the first PDSCH transmission is a dynamically scheduled PDSCH or a second SPS PDSCH;

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

and an operation behavior 3, determining target HARQ-ACK information which needs to be fed back by the first HARQ process based on a second preset rule under the condition that the first HARQ process corresponds to M effective second HARQ-ACK information, 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, for the first SPS PDSCH transmission, the first HARQ process may be occupied based on a predefined rule, and the terminal may perform SPS PDSCH reception and decoding based on the HARQ process and feed back corresponding HARQ-ACK information, which may also be referred to as SPS HARQ-ACK.

Optionally, the PDSCH transmission corresponds to HARQ-ACK information one-to-one, the HARQ process may correspond to one or more valid HARQ-ACK information, and the valid second HARQ-ACK information refers to HARQ-ACK information that is not discarded and needs or can 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. Optionally, in some embodiments, the first PDSCH transmission may be understood as a new dynamically scheduled PDSCH transmission or a new SPS PDSCH transmission, or as other PDSCH transmissions subsequently occupying the first HARQ process.

For the operation behavior 1, it may be understood that further occupation of the first HARQ process is limited, for example, in a case that the first HARQ-ACK information corresponding to the first HARQ process is transmitted in a delayed manner, it is ensured 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 in a delayed manner (delayed) as much as possible. Alternatively, in case that it is determined that the delay occurs based on a delay rule (delayed rules), the first HARQ-ACK information transmitted with delay may be understood as delayed SPS HARQ-ACK (delayed SPS HARQ-ACK) information.

When adopting operation behavior 1, 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 instant, so that implementation of the terminal may be simplified. In addition, the delayed HARQ-ACK information can be used for retransmission scheduling judgment and wireless link adaptation, 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 is finished. In some embodiments, it may also be understood that the terminal does not expect to receive the first PDSCH corresponding to the first HARQ process until the first time arrives.

As shown in fig. 3, in some embodiments, if the feedback of the HARQ-ACK information corresponding to the first HARQ process occupied by the SPS PDSCH collides with the downlink symbol, and a delay occurs, the HARQ-ACK information will be delayed from being transmitted in the next uplink transmission time unit. And the network side equipment transmits the first PDSCH for the first HARQ process after receiving the delayed HARQ-ACK information, for example, dynamically scheduling the PDSCH.

For operation behavior 2, it may be understood that the terminal decides whether to discard the first HARQ-ACK information based on a first preset rule. It should be appreciated 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 for delayed transmission, 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 subsequently.

When adopting operation behavior 2, 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 dynamically scheduled PDSCH transmission or the SPS PDSCH transmission for the SPS HARQ process based on the DCI of the network side device or the configuration information of the SPS Config (configuration), that is, the start time of the dynamically scheduled PDSCH transmission or the SPS PDSCH transmission is located after the initial SPS HARQ-ACK feedback time.

For operation behavior 3, neither additional scheduling restrictions nor discarding delayed first HARQ-ACK information is considered. This can be understood as follows: for a certain SPS HARQ process, the scheduling limitation corresponding to the initial SPS HARQ-ACK feedback time corresponding to the corresponding SPS PDSCH transmission is only needed to be observed. It should be understood that, when receiving the target HARQ-ACK information, the network side device needs to determine PDSCH transmission corresponding to the target HARQ-ACK information based on a second preset rule. That is to say, under the condition 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 operation behaviors may include both operation behavior 1 and operation behavior 2, and in this case, both the additional scheduling constraint and the dropping of the delayed first HARQ-ACK information are considered. For example, if the first HARQ-ACK information corresponding to the first HARQ process is not 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 operation behavior 2, and perform a corresponding discarding behavior when the first HARQ-ACK information is discarded.

In the embodiment of the application, under the condition that a first HARQ process is occupied by a first half persistent scheduling physical downlink shared channel (SPS), a terminal determines an operation behavior associated with 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 a first PDSCH transmission, wherein the first PDSCH transmission is a dynamically scheduled 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 needing 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 determined, 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 second time instant for the first PDSCH transmission is equal to or later than the first time instant.

In this 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 of the following: a time of the first PDSCH transmission, a time of a Physical Downlink Control Channel (PDCCH) transmission corresponding to the first PDSCH transmission, and a time of a HARQ-ACK feedback corresponding to the first PDSCH transmission.

In this embodiment, the first PDSCH transmission may be a dynamically scheduled PDSCH or an SPS PDSCH. The time of the first PDSCH transmission may be the start time or the end time of the first PDSCH transmission, which may also be referred to as the start time.

The PDCCH transmission corresponding to the first PDSCH transmission may be understood as that the DCI carried by the PDCCH transmission is used to schedule the first PDSCH transmission, and at this time, the first PDSCH transmission may be understood as a dynamically scheduled PDSCH. Alternatively, the time of PDCCH transmission may be understood as the starting time or the ending time of PDCCH transmission.

The time when the HARQ-ACK feedback corresponding to the first PDSCH is transmitted may be understood as a start time or an end time of an uplink channel on which the HARQ-ACK feedback corresponding to the first PDSCH is transmitted, 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).

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

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

In this embodiment, the uplink channel may be a PUCCH or a PUSCH. Actually carrying the first HARQ-ACK information transmission may be understood as actually transmitting in the target time unit based on a delay rule, or may be understood as actually transmitting based on DCI trigger. Including, for example, transmissions in a triggered Type 3codebook (Type-3 codebook) or an enhanced Type-3 codebook.

The time instant corresponding to the maximum delay may be understood as the start time instant or the end time instant of the time unit corresponding to the maximum delay. Wherein, the maximum delay can be directly configured by Radio Resource Control (RRC) or determined based on K1 set (set) configured by higher layer. It can refer to the maximum number of delay time units k1 relative 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, which can also be referred to as the initial time unit) _def The maximum number of feedback offset time elements k1 may be set to the time element in which the SPS PDSCH ends _eff ＝k1+k1 _def . The time unit corresponding to the maximum delay may be determined based on a value of the maximum delay, an initial SPS HARQ-ACK feedback time unit, or a time unit in which the SPS PDSCH end time is located. In this embodiment, the time unit may be a slot (slot) or a sub-slot (sub-slot).

It should be noted that the defered first HARQ-ACK information corresponding to the first HARQ process may trigger actual transmission based on Deferring rules or DCI in a time unit before a time unit corresponding to the maximum delay, may trigger actual transmission based on Deferring rules or DCI in a time unit corresponding to the maximum delay, or may not be actually transmitted even at the end time of the timeslot/sub-timeslot corresponding to the maximum delay. Assuming that an expected transmission time corresponding to the delayed first HARQ-ACK information corresponding to the first HARQ process is at the latest the 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 used as the standard, otherwise, the latest expected transmission time is used as the standard. Therefore, in the embodiment of the present application, the first time may be set to be a time earlier than the first time in the time unit corresponding to the maximum delay and the time of the first object.

Optionally, in some embodiments, the first preset rule comprises 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 HARQ-ACK feedback time corresponding to the first PDSCH transmission may be further defined. For example, in a case that 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 satisfies a preset condition;

wherein the preset condition comprises at least one of the following:

an 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 end time of the first PDSCH transmission is equal to or earlier than a first preset time, the first preset time is the start time or the end time of a first target channel, 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;

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, the term equal to or earlier than is understood to mean not later than. Optionally, the second target channel may be a PUCCH or a PUSCH. The first HARQ process being scheduled for the first PDSCH transmission may be understood as the first HARQ process being scheduled for dynamically scheduled 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: an initial feedback time of the first HARQ-ACK information; a time in a delay process 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 is determined that the first HARQ process has been scheduled for dynamic PDSCH transmission or configured for second SPS PDSCH transmission, the terminal may directly discard the first HARQ-ACK information without delaying the first HARQ-ACK information corresponding to the first HARQ process. 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 the starting time of an uplink channel used 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 (Defer) process, assuming that it has been determined at time 2 that the first HARQ process has been scheduled for dynamic PDSCH transmission or configured for second SPS PDSCH transmission, the terminal discards the defered SPS HARQ-ACK corresponding to the given SPS HARQ process and does not perform further deferring on this first HARQ-ACK.

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

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

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

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

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

the end time of the dynamically scheduled PDSCH transmission is not later than the start/end time of the PUCCH Resource (Resource) carrying the SPS HARQ-ACK in the initial time unit.

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

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

In this embodiment of the present application, after determining, based on Deferring rules, that HARQ-ACK information corresponding to a first HARQ process is delayed, a delay process may exist, and a start time of the delay process may be an 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 of:

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

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

In this embodiment, the third target channel may be a PUCCH or a PUSCH.

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

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

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

the fourth time instant is after the start time instant of the first PDSCH transmission and has a first time offset from the start time instant of the first PDSCH transmission;

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

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

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

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

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

Assuming that in the Defer process, 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 a corresponding time (e.g. time 3 shown in fig. 6) after a predefined offset is applied to the end time of this PDSCH transmission, the terminal discards the defered SPS HARQ-ACK corresponding to the given SPS HARQ process without further deferring the SPS HARQ-ACK.

For dynamic scheduling, it is considered here that the terminal needs to be occupied by dynamic PDSCH transmission for a given SPS HARQ process at the start/end time of dynamic PDSCH transmission, or at the end time of dynamic PDSCH transmission plus a time corresponding to a pre-defined time offset. The predefined time offset may be reported based on the terminal capability, or may be configured by a protocol or by a network device through signaling. For example, the predefined time offset may be determined based on N1 specified by the protocol, and optionally may be further determined in conjunction with terminal capability reporting or network parameter configuration. It is assumed that the terminal has already determined that a given SPS HARQ process needs to be occupied by this dynamic PDSCH transmission when it completes decoding of the dynamic PDSCH transmission and HARQ-ACK information preparation.

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

Optionally, in the Defer process, at the start/end 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 the defered SPS HARQ-ACK corresponding to the given SPS HARQ process, and does not perform further Defer on the SPS HARQ-ACK.

For dynamic scheduling, it is considered herein that when a terminal prepares to transmit or transmits HARQ-ACK feedback corresponding to a dynamic PDSCH transmission, it can already determine that the referred SPS HARQ-ACK corresponding to a given SPS HARQ process is no longer valid, or that HARQ-ACK information corresponding to the SPS HARQ process is covered by HARQ-ACK information of a further scheduled dynamic PDSCH transmission, so that it is not necessary to retransmit the referred SPS HARQ-ACK corresponding to the SPS HARQ process.

For the SPS PDSCH transmission, if the SPS HARQ-ACK corresponding to the second SPS PDSCH transmission already covers the referred SPS HARQ-ACK, then the referred SPS HARQ-ACK corresponding to the SPS HARQ process does not need to be retransmitted. It should be appreciated that the PUCCH/PUSCH transmissions corresponding to the second SPS PDSCH transmission may also have collision problems for the TDD system, and if collision occurs, deferring rules are applied for the HARQ-ACK corresponding to the second SPS PDSCH transmission.

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

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

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

when any second PDSCH transmission does not meet the HARQ-ACK feedback timeline requirement, 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 satisfy the HARQ-ACK feedback timeline requirements, it may be understood that none of the second PDSCH transmissions satisfy the HARQ-ACK feedback timeline requirements. All bits corresponding to the target HARQ-ACK information are negative acknowledgments, which may be understood as that each bit of the target HARQ-ACK information is a negative acknowledgment.

In the embodiment of the application, for a certain SPS HARQ process, only scheduling limitation corresponding to the initial SPS HARQ-ACK feedback time corresponding to the corresponding SPS PDSCH transmission needs to be observed, and scheduling limitation of operation behavior 1 does not need to be introduced, and meanwhile, a decision rule considered in operation behavior 2 is not considered, and defered SPS HARQ-ACK is discarded when the rule is satisfied.

At this time, when another Codebook Type (HARQ-ACK Codebook Type) other than Type-3Codebook is adopted, based on the respective Codebook structure flows, there may be a case where HARQ-ACK information corresponding to multiple PDSCH transmissions corresponding to the same HARQ process is all included in the same Codebook for transmission, and at this time, the terminal may set HARQ-ACK bits corresponding to multiple PDSCH transmissions corresponding to the same HARQ process according to HARQ-ACK information transmitted by each PDSCH. After receiving the HARQ-ACK codebook fed back by the terminal, the network side device may implement processing of the HARQ-ACK information, for example, for multiple PDSCH transmissions corresponding to the same HARQ process, only use the HARQ-ACK information corresponding to the later PDSCH transmission in the PDSCH transmissions, and discard the HARQ-ACK information corresponding to the earlier PDSCH transmission. When the Type-3Codebook is adopted, a corresponding rule may be defined, and the UE determines, based on the rule, which HARQ-ACK information to use for the HARQ process when there is more than one corresponding HARQ-ACK information for the same HARQ process (each HARQ-ACK information corresponds to one PDSCH transmission corresponding to the HARQ process and is still in a valid state, for example, for SPS HARQ-ACK requiring Defer, it is still in a state that it can be fed back, and for scheduled dynamic PDSCH transmission or configured SPS PDSCH transmission, its corresponding HARQ-ACK is still in a state that it can be fed back or fed back), and specifically determines, when constructing the Codebook, which HARQ-ACK information to use for the HARQ process according to the following manner:

mode 1: aiming at the HARQ process, the corresponding HARQ-ACK information is always transmitted by adopting the last or the last PDSCH;

mode 2: and aiming at the HARQ process, the latest PDSCH which meets the requirement of HARQ-ACK feedback time is always adopted to transmit the corresponding HARQ-ACK information, and when the PDSCH transmission does not meet the requirement, the HARQ-ACK bit corresponding to the HARQ process can be set as NACK.

It should be understood that the terminal may indicate in the capability information whether the above certain operation behavior or behaviors are supported and/or configured by the network side device to adopt the above certain operation behavior. The operation behaviors here include an operation behavior 1, an operation behavior 2, and an operation behavior 3.

Optionally, a relationship between a first SPS PDSCH transmission occupying the first HARQ process and a physical layer Priority (Priority indicator, which may be indicated in DCI or configured by high layer signaling, and indicates a Priority of a PUCCH transmission carrying its corresponding HARQ-ACK feedback for a PDSCH transmission) of another PDSCH transmission subsequently occupying the first HARQ process (i.e., the first PDSCH transmission) may also be considered to determine whether some or more of the above operation behaviors are supported.

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 the first PDSCH transmission subsequently occupying the first HARQ process is the subsequent priority:

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

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 of the high priority (that is, the performance of HARQ-ACK feedback corresponding to SPS PDSCH transmission occupying the first HARQ process) needs to be preferentially ensured, and at this time, only operation behavior 1 may be supported. Optionally, operation behavior 3 may be further supported (when the Type-3codebook is not used to trigger HARQ-ACK feedback, the preferred SPS HARQ-ACK is not discarded). Optionally, the operational behavior supported may be determined distinguishing whether the first PDSCH transmission is a dynamically scheduled PDSCH transmission or an SPS PDSCH transmission. For example, when the first PDSCH transmission is a dynamically scheduled PDSCH transmission, the network side device may dynamically decide the scheduling condition at this time, so that 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 operational behavior 1, operational behavior 2, and operational behavior 3 may be supported, and/or employed by the network-side semi-static configuration or DCI dynamic indication, as the case of the SPS PDSCH transmission is a semi-static 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 HARQ-ACK feedback with the high priority may preempt the HARQ-ACK feedback with the low priority. It should be noted that, 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, the operation behavior 3 may be further supported (no restriction is required on the type of codebook employed).
