For ease of understanding, the following description refers to certain embodiments of the invention:

first, a Fallback Downlink Control Information (Fallback DCI) format or a non-Fallback DCI (non-Fallback DCI) format of NR

In the NR, uplink and downlink scheduling DCIs (Downlink control information) distinguish a Fallback DCI format and a non-Fallback DCI format, wherein the introduction of the Fallback DCI format mainly ensures the network coverage performance by simplifying scheduling indication information, the Fallback DCI format has fewer indication domains, the enablement or information indication of some expansion or optimization functions is limited, and generally, the indication domains corresponding to the expansion, optimization or optional functions configured by a distinguishable terminal are not contained; the non-Fallback DCI format focuses on more detailed indication of the guarantee scheduling indication information, and some extended or optimized functions may be started as needed, so that on the basis of the indication field in the Fallback DCI format, some other indication fields are added, for example, a corresponding indication field is added for the indication information of some extended, optimized or optional functions, an indication field list and a corresponding bit number included in a single DCI are related to a specific configuration of a certain terminal, and bit overhead is large.

HARQ-ACK feedback corresponding to SPS PDSCH for NR or enhanced high Reliable Low Latency Communication (eURLLC)

SPS PDSCH (periodically initiated PDSCH transmissions after downlink SPS transmissions are activated, which are transmitted based on a predefined manner without corresponding DCI indications) transmissions is introduced into a communication system. For downlink SPS transmission, the network device ensures that, in a certain serving cell group configured for the terminal, at most, only a single serving cell configures a semi-persistent scheduling configuration (SPS-Config) configuration item, a corresponding SPS PDSCH transmission interval is 10 milliseconds at minimum, and the SPS-Config configuration item includes a parameter n1PUCCH-AN, which is used to indicate a Physical Uplink Control Channel (PUCCH) resource used when the UE transmits only HARQ-ACK corresponding to the SPS PDSCH, and the PUCCH resource can carry 1-bit HARQ-ACK. 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 as much as possible, it is proposed that the network device may configure multiple sets of SPS-Config configuration items that are valid at the same time for a single UE (a certain Bandwidth Part (BWP) of a single serving cell may configure up to 8 sets at the same time), and the corresponding SPS PDSCH transmission interval may be shortened to a minimum of a single timeslot. At this time, when the terminal transmits only HARQ-ACK corresponding to the SPS PDSCH, the number of HARQ-ACK bits is also correspondingly extended to a plurality of bits. Therefore, in the eURLLC, the parameter n1PUCCH-AN may be extended to a parameter SPS-PUCCH-AN-List, which is used to indicate a PUCCH resource List, where at most 4 PUCCH resources may be included, different PUCCH resources correspond to different ranges of bit numbers, the ranges of bit numbers corresponding to these PUCCH resources are mutually adjacent to form a single complete range of bit numbers, and the threshold corresponding to the adjacent point, that is, the upper bound of the range of bit numbers corresponding to a single PUCCH resource (which plus one constitutes the lower bound of the range of bit numbers corresponding to the next PUCCH resource), may be given in a high-level configuration, or may be a default value 1706. And the terminal selects a certain PUCCH resource in the PUCCH resource list according to the number of HARQ-ACK bits which are actually required to be transmitted and only correspond to the SPS PDSCH (when the number of HARQ-ACK bits corresponding to the SPS PDSCH which does not contain Cyclic Redundancy Check (CRC) check bits falls within the range of the number of bits of the PUCCH resource) to carry the HARQ-ACK corresponding to the SPS PDSCH.

Three, NR HARQ-ACK dynamic codebook

When the UE organizes the HARQ-ACK bit sequence that needs to be reported at a certain feedback time, the UE determines a corresponding relationship between each PDSCH transmission and a certain bit/certain bits in the organized HARQ-ACK bit sequence based on a predefined rule and a scheduling condition of Physical Downlink Shared Channel (PDSCH) transmission on a single/multiple carriers that need to report HARQ-ACK at the feedback time, and this operation is called constructing a HARQ-ACK Codebook (Codebook).

When a Semi-Persistent Scheduling (SPS) PDSCH release is indicated by Downlink Control Information (DCI), the terminal is also required to acknowledge its reception using the HARQ-ACK bit to ensure that the understanding of both sides on whether the SPS PDSCH is in an active state is consistent.

The HARQ-ACK Codebook includes: a semi-static codebook (Type-1) and a dynamic codebook (Type-2). The former feeds back all possible DCI indication and PDSCH transmission, and is mainly used for ensuring transmission reliability, and the feedback overhead is large; the latter only feeds back the actual DCI indication and PDSCH transmission, so that the feedback overhead is low, and the transmission reliability can be influenced to a certain extent when the DCI missing detection condition is common.

The dynamic codebook reserves HARQ-ACK feedback bits for each actually used DAI value in a manner of counting Downlink Assignment Index (DAI) for actually scheduled PDSCH transmission or SPS PDSCH release indication. If the terminal presumes that the PDSCH allocation indication or the SPS PDSCH release indication corresponding to some DAIs is not received through other detected DAIs, setting corresponding feedback bits as NACK; otherwise, setting HARQ-ACK feedback bits corresponding to the PDSCH transmission decoding results according to the PDSCH allocation indications, and setting the feedback bits corresponding to the detected SPS PDSCH release indications as ACK.

The DAI is indicated by using a limited number of bits (a single DAI generally occupies 2 bits), and in order to expand the indication range, a modular operation is introduced, namely, the DAI is sequentially counted from 1 and then is modular to obtain a DAI value corresponding to a certain count value. The processing of DAI in downlink scheduling can refer to the following table.

The value of the counter DAI in DCI Format 1_0, and the value of the counter DAI or total number DAI in DAI DCI Format 1_1

In the above table, the Most Significant Bit (Most Significant Bit, MSB); least Significant Bit (LSB); counter DAI (Counter DAI, C-DAI); total DAI (Total DAI, T-DAI).

Y is the Number of serving cell and PDCCH monitoring opportunity pairs (Number of serving cell and PDCCH monitoring opportunity pairs) with the PDCCH indicating the SPS PDSCH release, or the associated with the PDCCH or PDCCH indicating the SPS PDSCH release, and Y is more than or equal to 1.

When the terminal is configured with a plurality of serving cells, in order to further increase reliability, a T-DAI is newly introduced, which is used to indicate the number of all DCI indications received up to the current time domain detection position, including all DCI indications received by the current time domain detection position on each serving cell, so that the value of the T-DAI is updated only when the time domain detection position changes.

The T-DAI and the C-DAI are used in combination, so that the situation that when the DCI indication on a certain serving cell or certain serving cells is lost at a certain time domain detection position (as long as the DCI indication on all the serving cells is not lost), the terminal and the network equipment have inconsistent understanding on the transmission of the DCI indication can be effectively avoided.

Four, NR-U HARQ-ACK dynamic codebook enhancement

The enhancements introduced for the dynamic codebook mainly include the following:

performing explicit grouping on the PDSCH which is dynamically scheduled, and indicating a grouping corresponding to the PDSCH which is scheduled in the scheduling DCI; HARQ-ACK feedbacks corresponding to the same PDSCH packet are all carried on the same PUCCH;

C-DAI or T-DAI counting within a single PDSCH packet;

each PDSCH group maintains a New Feedback Indicator (NFI), and indicates whether to transmit New Feedback or to retransmit previous Feedback in a turnover mode; if NFI is turned over, indicating that all feedbacks of DCI turned over for the PDSCH grouping before the DCI is discarded, and only transmitting the DCI and HARQ-ACK feedbacks of PDSCH scheduled for the PDSCH grouping after the DCI is turned over, if the NFI is not turned over, all HARQ-ACK feedbacks for the PDSCH grouping need to be transmitted since the last NFI turning over, namely, the HARQ-ACK feedbacks with the same NFI value are all effective; therefore, for two feedback requests of the same PDSCH grouping, the number of HARQ-ACK bits actually required to be transmitted may change;

a single DCI may request HARQ-ACK feedback of one to multiple PDSCH packets to be transmitted on the same PUCCH, typically, a single downlink scheduling DCI may request HARQ-ACK feedback of a PDSCH packet corresponding to a PDSCH scheduled by itself by default, and this DCI may additionally trigger HARQ-ACK feedback of other PDSCH packets to be transmitted on a PUCCH indicated by the DCI together;

the maximum number of supported PDSCH packets is 2;

the terminal may indicate whether the enhanced dynamic codebook is supported through the capability information.

The NR-U does not separately consider SPS PDSCH with respect to HARQ-ACK dynamic codebook and dynamic codebook enhancement, and the HARQ-ACK processing method according to the embodiment of the present invention is described below.

Referring to fig. 2, fig. 2 is a flowchart of a HARQ-ACK processing method according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201, determining N2 first PDSCH packets to which N1 SPS PDSCHs belong, where N1 and N2 are both positive integers, and N1 is greater than or equal to N2, where the N2 first PDSCH packets are used to determine N2 first bit sequences, and the N2 first bit sequences include HARQ-ACKs corresponding to the N1 SPS PDSCHs;

step 202, a target dynamic codebook including the N2 first bit sequences is generated, where the N2 first bit sequences are located at the tail of the target dynamic codebook, or the first bit sequences are located at the tail of target bit sequences corresponding to a target PDSCH packet, and the target PDSCH packet is a first PDSCH packet corresponding to the first bit sequences.

In this embodiment of the present invention, the N2 first PDSCH packets are part or all of PDSCH packets corresponding to or related to the target dynamic codebook. The above target dynamic codebook may be understood as a dynamic codebook supporting PDSCH packet correlation enhancement, i.e. a HARQ-ACK bit sequence to be fed back. HARQ-ACKs corresponding to one or more SPS PDSCH transmissions within the same first PDSCH packet may constitute one first bit sequence. The SPS PDSCH mentioned later may all be understood as SPS PDSCH transmission. When N1 SPS PDSCH packets are attributed to multiple PDSCH packets, multiple first bit sequences may be generated correspondingly, each PDSCH packet corresponding to a single first bit sequence. When a dynamic codebook (i.e. the above target dynamic codebook) is constructed, a plurality of first bit sequences may be placed at specified positions, so as to implement feedback of HARQ-ACK corresponding to SPS PDSCH.

The maximum number M of PDSCH packets supported by the enhanced dynamic codebook can be regulated by a protocol or set according to actual needs, and the N2 is determined based on the PDSCH packet condition that N1 SPS PDSCHs belong to, wherein N2< ═ M. In the examples of the present invention, N2 ═ 2 is exemplified for the details. At this time, the N2 first PDSCH packets may include PDSCH packet 0 and PDSCH packet 1, and it may be determined that the N2 first bit sequences include bit sequence 0 and bit sequence 1 based on the first PDSCH packet to which the N1 SPS PDSCH belongs, where bit sequence 0 corresponds to PDSCH packet 0 and bit sequence 1 corresponds to PDSCH packet 1.

In an optional embodiment, if the N2 first bit sequences are located at the tail of the target dynamic codebook, bit sequence 0 and bit sequence 1 may be concatenated according to a preset manner, and the concatenated whole bit sequence is located at the tail of the target dynamic codebook. The target dynamic codebook may include only bit sequence 0 and bit sequence 1, and may also include HARQ-ACK corresponding to DCI in addition to bit sequence 0 and bit sequence 1. The DCI here may include DCI scheduling PDSCH transmission and DCI indicating SPS PDSCH release, where each DCI may indicate C-DAI and, in some cases, T-DAI. In this case, the entire concatenated bit sequence of bit sequence 0 and bit sequence 1 is located after the bit sequence of HARQ-ACK corresponding to DCI. In other words, in this embodiment of the present invention, when the N2 first bit sequences are located at the tail of the target dynamic codebook, the target dynamic codebook includes only the first bit sequence, or the target dynamic codebook includes the first bit sequence and a second bit sequence, and the second bit sequence corresponds to the DCI in all the PDSCH packets corresponding to the HARQ-ACK carried by the target dynamic codebook. It should be understood that the PDSCH packet corresponding to DCI in the target dynamic codebook may not include the first PDSCH packet, and may also include part or all of the first PDSCH packet, which is not further limited herein.

In another optional embodiment, if the first bit sequence is located at the tail of the target bit sequence corresponding to the target PDSCH packet, it may be understood that bit sequence 0 is located at the tail of the target bit sequence corresponding to PDSCH packet 0, and bit sequence 1 is located at the tail of the target bit sequence corresponding to PDSCH packet 1. It should be noted that, when the first bit sequence is located at the tail of the target bit sequence corresponding to the target PDSCH packet, the target bit sequence only includes the first bit sequence, or the target bit sequence includes the first bit sequence and a third bit sequence, and the third bit sequence corresponds to the downlink control information DCI in the first PDSCH packet corresponding to the first bit sequence. For example, the PDSCH packet 0 may or may not include DCI-corresponding HARQ-ACK, and the PDSCH packet 1 may or may not include DCI-corresponding HARQ-ACK. The description is given with respect to the case where PDSCH packet 0 does not include HARQ-ACK corresponding to DCI, and PDSCH packet 1 includes HARQ-ACK corresponding to DCI, at this time, the target bit sequence corresponding to PDSCH packet 0 only includes bit sequence 0, the target bit sequence corresponding to PDSCH packet 1 includes bit sequence 1 and the bit sequence formed by HARQ-ACK corresponding to DCI in PDSCH packet 1, and bit sequence 1 is located after the bit sequence formed by HARQ-ACK corresponding to DCI in PDSCH packet 1.

In the embodiment of the invention, a PDSCH packet to which an SPS PDSCH belongs is defined, the PDSCH packet is used for determining HARQ-ACK bits corresponding to the SPS PDSCH, and the HARQ-ACK bit sequence corresponding to the SPS PDSCH is arranged in a dynamic codebook based on the PDSCH packet. Therefore, the embodiment of the invention realizes that the HARQ-ACK corresponding to the SPS PDSCH is brought into a PDSCH grouping design frame, can support the feedback of the HARQ-ACK corresponding to the SPS PDSCH, and improves the transmission reliability and the expandability of the HARQ-ACK.

It should be noted that, the determination manner for the PDSCH packets to which N1 SPS PDSCHs belong may be set according to actual needs, for example, in the embodiment of the present invention, the determining N2 first PDSCH packets to which N1 SPS PDSCHs belong includes any one of the following:

determining that the first PDSCH packet to which the N1 SPS PDSCHs belong is a default PDSCH packet;

and determining a first PDSCH grouping to which the SPS PDSCH belongs according to the DCI activating the SPS PDSCH.

Here, the default packet may be PDSCH packet 0, and in this case, it may be considered that N1 SPS PDSCHs are collectively assigned to PDSCH packet 0. The DCI activating the SPS PDSCH generally includes two types of DCI, for example, fallback DCI and non-fallback DCI are generally included, and a PDSCH grouping indication is generally included in the non-fallback DCI, so in the embodiment of the present invention, a PDSCH grouping to which the SPS PDSCH belongs may be determined based on the type of DCI. Specifically, in this embodiment of the present invention, the determining, according to the DCI activating the SPS PDSCH, the first PDSCH packet to which the SPS PDSCH belongs includes:

determining that a first PDSCH packet to which the SPS PDSCH belongs is a PDSCH packet indicated by the non-fallback DCI under the condition that the DCI is the non-fallback DCI;

and determining that the first PDSCH packet to which the SPS PDSCH belongs is a default PDSCH packet under the condition that the DCI is fallback DCI.

The embodiment of the invention determines the home PDSCH grouping of the SPS PDSCH activated by the backspacing DCI and the SPS PDSCH activated by the non-backspacing DCI according to different modes, thereby improving the flexibility of the PDSCH grouping.

In the embodiment of the present invention, the position definition for the first bit sequence includes the following two schemes.

Scheme 1: the first bit sequence is positioned at the tail part of the target dynamic codebook;

scheme 2: the first bit sequence is located at the end of the target bit sequence corresponding to the target packet.

With respect to scheme 1, in the case where the number of first bit sequences is 1 (i.e., N2 is 1), the first bit sequence is directly set at the end of the target dynamic codebook. In case that N2 is greater than 1 (i.e., the number of the first bit sequences is greater than 1), the N2 first bit sequences may be concatenated in an increasing order of the group number of the PDSCH packets.

With respect to the above scheme 2, it can be understood that each first bit sequence is located at the tail of the corresponding target bit sequence, in other words, the HARQ-ACK corresponding to the SPS PDSCH corresponding to each PDSCH packet is located at the tail of the HARQ-ACK bit sequence corresponding to the PDSCH packet.

As for the composition of the first bit sequence in the above-described scheme 1 and scheme 2, a case where the same PDSCH packet includes SPS PDSCH transmitted by one or more serving cells and a case where SPS PDSCH transmitted by the same serving cell belongs to 1 or more SPS configurations may be considered, and the composition of the first bit sequence is described in detail below for each case.

Optionally, in an embodiment, the first bit sequence satisfies:

under the condition that the SPS PDSCH corresponding to the first bit sequence belongs to a single serving cell, the first bit sequence is a fourth bit sequence, and the fourth bit sequence is determined by HARQ-ACK corresponding to the SPS PDSCH in the serving cell;

and under the condition that the SPS PDSCH corresponding to the first bit sequence belongs to L serving cells, the first bit sequence is obtained by cascading L fourth bit sequences, the fourth bit sequences are determined by HARQ-ACK corresponding to the SPS PDSCH in the same serving cell, and L is an integer larger than 1.

The first bit sequence is obtained by sequentially cascading the L fourth bit sequences according to the index sequence of the serving cell. For example, concatenation may be performed in ascending order based on serving cell index. For example, the L fourth bit sequences include a bit sequence 0a and a bit sequence 0b, where the bit sequence 0a corresponds to the serving cell 0 and the bit sequence 0b corresponds to the serving cell 1. At this time, after the bit sequence 0a and the bit sequence 0b are concatenated according to the serving cell index, the bit sequence 0a is located before the bit sequence 0 b. It should be understood that, in other embodiments, the first bit sequence may be obtained by cascading the L fourth bit sequences sequentially based on the descending order of the serving cell indexes.

Optionally, in this embodiment of the present invention, it may be considered that SPS PDSCHs sent by N1 SPS dschs needing HARQ-ACK feedback on a certain serving cell s belong to one or more downlink SPS configurations, each downlink SPS configuration corresponds to a configuration index, and the configuration index uniquely identifies the downlink SPS configuration within an active BWP range of the serving cell s. The fourth bit sequence corresponding to the SPS PDSCH for a single serving cell at this time may be considered to be determined in the following manner.

In an embodiment, the fourth bit sequence satisfies at least one of the following conditions:

under the condition that the first SPS PDSCH corresponding to the fourth bit sequence belongs to J SPS configurations and J is 1, the fourth bit sequence is a fifth bit sequence, and the fifth bit sequence is obtained by arranging HARQ-ACK (hybrid automatic repeat request-acknowledgement) corresponding to the first SPS PDSCH according to the sequence of the transmission starting time of the SPS PDSCH;

and under the condition that the first SPS PDSCH corresponding to the fourth bit sequence belongs to J SPS configurations and J is an integer larger than 1, cascading J fifth bit sequences to obtain the fourth bit sequence, wherein the fifth bit sequences are HARQ-ACK (hybrid automatic repeat request-acknowledgement) corresponding to the first SPS PDSCH of the same SPS configuration and are obtained by arranging the HARQ-ACK corresponding to the first SPS PDSCH of the same SPS configuration according to the sequence of the starting transmission time of the SPS PDSCH.

The order of the J fifth bit sequence concatenations may be an ascending configuration index concatenation according to the SPS configuration. In other words, in this embodiment, the starting transmission time of the SPS PDSCH of a single downlink SPS configuration may be traversed (alternatively, the starting transmission time may be arranged from front to back according to the SPS PDSCH transmission time), and then the downlink SPS configurations may be traversed (alternatively, the starting transmission time may be arranged from small to large according to the downlink SPS configuration index). For example, in this embodiment, the number of the first SPS PDSCHs corresponding to the fourth bit sequence is 4, and the corresponding HARQ-ACK including 4 bits (A, B, C and D indicate 4 HARQ-ACK bits corresponding to 4 first SPS PDSCHs), where the first SPS PDSCHs corresponding to a and B belong to SPS configuration 1; the first SPS PDSCH corresponding to C and D belongs to SPS configuration 2; the transmission start time of the first SPS PDSCH corresponding to a is time 1, the transmission start time of the first SPS PDSCH corresponding to B is time 2, the transmission start time of the first SPS PDSCH corresponding to C is time 3, the transmission start time of the first SPS PDSCH corresponding to D is time 4, and the sequence order of the transmission start times from first to last is: time 2, time 3, time 1, and time 4. At this time, first, the transmission starting time of the SPS PDSCH of the single downlink SPS configuration is traversed to obtain a fifth bit sequence corresponding to the single downlink SPS configuration, including a BA and a CD, and then, the downlink SPS configurations are traversed, that is, the two fifth bit sequences are cascaded in an ascending order according to the configuration index to obtain a fourth bit sequence (i.e., a BACD). It should be understood that, in other embodiments, the order of the concatenation of the J fifth bit sequences may also be in descending order according to the configuration index of the SPS configuration.

In another embodiment, the fourth bit sequence satisfies at least one of:

under the condition that the transmission starting time of the first SPS PDSCH corresponding to the fourth bit sequence is located in 1 time slot, the fourth bit sequence is a sixth bit sequence, and the sixth bit sequence is obtained by arranging HARQ-ACK corresponding to the first SPS PDSCH according to the sequence of SPS configuration indexes;

and under the condition that the transmission starting time of the first SPS PDSCH corresponding to the fourth bit sequence is located in K time slots, the fourth bit sequence is obtained by cascading K sixth bit sequences, and the sixth bit sequences are obtained by arranging HARQ-ACK (hybrid automatic repeat request-acknowledgement) corresponding to the first SPS PDSCH in the same time slot according to the sequence of SPS configuration indexes.

The sixth bit sequence may be cascaded according to the sequence of the time slots. In other words, in this embodiment, it can be understood that the downlink SPS configurations in each transmission slot are traversed (typically, the downlink SPS configurations may be arranged from small to large according to the downlink SPS configuration index), and then the transmission slots are traversed (only the time slot in which the SPS PDSCH transmission exists and the HARQ-ACK thereof needs to be fed back in the dynamic codebook is taken as the transmission slot to be traversed; typically, the time slots may be ordered from large to small according to the time interval between the transmission slot and the transmission slot of the dynamic codebook, in other words, arranged from front to back according to the starting time of the transmission slot).

For example, in this embodiment, the number of the first SPS PDSCHs corresponding to the fourth bit sequence is 4, and the corresponding HARQ-ACK including 4 bits (A, B, C and D indicate 4 HARQ-ACK bits corresponding to 4 first SPS PDSCHs), where the first SPS PDSCHs corresponding to a and B belong to SPS configuration 1; the first SPS PDSCH corresponding to C and D belongs to SPS configuration 2; the transmission start time of the first SPS PDSCH corresponding to a is time 1, the transmission start time of the first SPS PDSCH corresponding to B is time 2, the transmission start time of the first SPS PDSCH corresponding to C is time 3, the transmission start time of the first SPS PDSCH corresponding to D is time 4, and the sequence order of the transmission start times from first to last is: time 2, time 3, time 1, and time 4, and time 2 and time 3 are located in time slot 1, time 1 and time 4 are located in time slot 2, and time slot 2 is located after time slot 1. At this time, first, the SPS configurations in the transmission timeslot are traversed to obtain a sixth bit sequence (BC and AD) corresponding to each timeslot, and then, the SPS configurations in the transmission timeslot are traversed to obtain a fourth bit sequence (i.e., BCAD).

In another embodiment, the fourth bit sequence is obtained by arranging HARQ-ACKs corresponding to SPS PDSCHs in the same serving cell according to the sequence of the start transmission time of the SPS PDSCHs.

In this embodiment, the transmission start time of the SPS PDSCH may be directly traversed without distinguishing which downlink SPS configuration each SPS dsch specifically corresponds to, and it is assumed that for an active BWP of a single serving cell (only a single BWP in an active state exists in a single serving cell at any time), there is no time-domain overlap between durations of any two SPS PDSCH transmissions. For example, in this embodiment, the number of the first SPS PDSCHs corresponding to the fourth bit sequence is 4, and the corresponding HARQ-ACK including 4 bits (A, B, C and D indicate 4 HARQ-ACK bits corresponding to 4 first SPS PDSCHs), where the first SPS PDSCHs corresponding to a and B belong to SPS configuration 1; the first SPS PDSCH corresponding to C and D belongs to SPS configuration 2; the transmission start time of the first SPS PDSCH corresponding to a is time 1, the transmission start time of the first SPS PDSCH corresponding to B is time 2, the transmission start time of the first SPS PDSCH corresponding to C is time 3, the transmission start time of the first SPS PDSCH corresponding to D is time 4, and the sequence order of the transmission start times from first to last is: time 2, time 3, time 1, and time 4. The fourth bit sequence can be directly obtained as the BCAD through traversal.

It should be further noted that the determination of the SPS PDSCH requiring feedback of HARQ-ACK in one PDSCH packet may be determined in one of the following manners:

mode 1: and the HARQ-ACK feedback time slots corresponding to the N1 SPS PDSCHs are the same as the transmission time slot of the target dynamic codebook.

Mode 2: the start transmission time of the target SPS PDSCH is within the target time period.

The target SPS PDSCH is any one of the N1 SPS PDSCHs, the starting time of the target time period is the NFI turning time which is closest to the starting transmission time of the target dynamic codebook in the first PDSCH group to which the target SPS PDSCH belongs, and the NFI turning time is located before the starting transmission time of the target dynamic codebook.

Optionally, the end time of the target time period includes any one of:

the starting transmission moment of the target dynamic codebook;

and a preset time interval is set between the transmission starting time of the target dynamic codebook and the transmission starting time of the target dynamic codebook.

With respect to the above mode 1, the embodiment of the present invention may be understood as follows: only HARQ-ACKs corresponding to SPS PDSCH whose feedback slot of HARQ-ACK coincides with the target dynamic codebook transmission slot are considered. Optionally, the feedback time slot of the HARQ-ACK corresponding to the SPS PDSCH may be determined based on the DCI activating the SPS PDSCH.

With respect to the above mode 2, the embodiment of the present invention may be understood as considering HARQ-ACKs corresponding to all SPS PDSCHs within a specified end time (i.e. the end time of the above target time period) from the beginning of the last NFI flip of the PDSCH packet to which the SPS PDSCH belongs (e.g. taking the system time of the PDSCH packet to which the SPS PDSCH belongs when the NFI flip is the last time from the target dynamic codebook transmission as a reference time, and taking the SPS PDSCH belonging to the PDSCH packet with the transmission start time after the reference time as a feedback range). For these SPS PDSCH, its corresponding NFI may be considered as the NFI value after the last NFI flip, and this NFI value corresponds to the PDSCH packet to which the SPS PDSCH belongs.

The specified ending time can be determined in some way as follows:

the HARQ-ACK feedback time slot corresponding to the latest SPS PDSCH (namely the HARQ-ACK feedback time slot n + k determined based on the time slot n in which the SPS PDSCH is transmitted and the HARQ-ACK feedback time slot offset k) is not later than the dynamic codebook transmission time slot.

The time interval between the ending time of the latest SPS PDSCH and the starting time of a PUCCH or a Physical Uplink Shared Channel (PUSCH) where the dynamic codebook is transmitted is not less than a preset value. The preset value may be determined by the capability of the terminal, for example, the duration corresponding to N1 symbols (optionally, further considering the influence of the timing advance TA), may be a protocol agreement, and may also be a network device configuration, which is not further limited herein.

The NFI rollover time determination method includes at least one of the following:

determining according to NFI explicitly indicated by DCI; the embodiment can be understood as follows: determining according to NFI explicitly indicated at the latest time from the starting transmission time of the target dynamic codebook in a first PDSCH packet to which the target SPS PDSCH belongs; when the NFI explicitly indicated and the corresponding NFI of the first PDSCH packet to which the target SPS PDSCH belongs before the explicit indication have different values, the NFI may be considered to be turned, and the transmission time of the explicit indication or the transmission start time of the explicit indication may be used as the NFI turning time. For example, when it is determined by an instruction in the non-fallback DCI scheduling the PDSCH transmission of the PDSCH packet and the NFI rollover is determined based on the NFI indicated in a certain non-fallback DCI, the transmission time or the transmission start time of the non-fallback DCI may be the NFI rollover time.

Determined according to NFI rollover rules agreed by the protocol. For example, when a certain dynamic codebook transmission corresponds to only fallback DCI scheduled PDSCH transmission or indicated SPS PDSCH release for a certain PDSCH packet, it is assumed that the NFI of the PDSCH packet is flipped from the first of these fallback DCIs. At this time, the transmission time or the transmission start time of the first fallback DCI may be the NFI flipping time.

It should be noted that NFI flip time may be different for different PDSCH packets.

Further, before step 201 is executed, HARQ-ACK included in the target dynamic codebook needs to be considered, that is, HARQ-ACK corresponding to SPS PDSCH needing to be transmitted and DCI scheduled PDSCH or indicated SPS PDSCH release corresponding HARQ-ACK need to be determined first.

For example, in an embodiment, before the step 201, the method further includes:

step 203, determining that the N1 SPS PDSCHs include SPS PDSCHs of which the HARQ-ACK feedback time slots are located in the target transmission time slots under the condition that the target transmission time slots corresponding to the target dynamic codebook are the same as the HARQ-ACK feedback time slots corresponding to part or all of the N1 SPS PDSCHs. The feedback time slot of the HARQ-ACK corresponding to the SPS PDSCH is determined by the DCI activating the SPS PDSCH.

Optionally, the N1 SPS PDSCHs further include SPS PDSCHs whose start transmission time instants are within the target time period.

Further, the method further comprises, after determining that the feedback slots where the N1 SPS PDSCHs contain HARQ-ACKs are located on SPS PDSCHs within the target transmission slot:

step 204, determining a first HARQ-ACK corresponding to the DCI as a HARQ-ACK in the target dynamic codebook except for the first bit sequence;

wherein the first HARQ-ACK satisfies any one of:

the feedback time slot of the first HARQ-ACK is the same as the target transmission time slot;

and under the condition that the terminal is configured with preset parameters, the first HARQ-ACK is the HARQ-ACK which triggers retransmission based on the N1 SPS PDSCHs.

The preset parameter may be AN SPS-PUCCH-AN-List.

The HARQ-ACK triggering retransmission based on the N1 SPS PDSCHs may be understood as HARQ-ACK transmission of the SPS PDSCH whose feedback time slot is the same as the target transmission time slot, and may trigger retransmission of the PDSCH packet to which the SPS PDSCH belongs and HARQ-ACK corresponding to the DCI, where these HARQ-ACKs are all included in the target dynamic codebook.

Optionally, in this embodiment, when the terminal configures a preset parameter, the transmission resource of the target dynamic codebook is a resource in a resource list corresponding to the preset parameter.

Further, in another embodiment, before the step 201, the method further includes:

step 205, under the condition that the target transmission time slot corresponding to the target dynamic codebook is different from the feedback time slots of the HARQ-ACKs corresponding to the N1 SPS PDSCHs, the N1 SPS PDSCHs include the SPS PDSCHs in the first PDSCH packet corresponding to the second HARQ-ACK, where the second HARQ-ACK is the HARQ-ACK corresponding to the DCI, and the feedback time slot is the same as the target transmission time slot. Here, the feedback time slot is the same as the target transmission time slot, and it can be understood that when HARQ-ACKs corresponding to DCI of one or more first PDSCH packets need to be included in the target dynamic codebook, the feedback time slots of these HARQ-ACKs are the same as the target transmission time slot.

For a better understanding of the specific implementation of the present invention, the following detailed description is directed to specific implementation processes of the present invention.

In the implementation of the invention, the SPS PDSCH does not have corresponding DAI, wherein the SPS PDSCH is uniformly attributed to a PDSCH group 0, or is attributed to the PDSCH group indicated in the Non-Fallback DCI when the SPS PDSCH transmission is activated by the Non-Fallback DCI, and is attributed to a default group, namely the PDSCH group 0, when the SPS PDSCH transmission is activated by the Fallback DCI.

The specific transmission scheme may include the following scheme one and scheme two.

The first scheme comprises the following steps: the HARQ-ACK bit corresponding to SPS PDSCH is always attached to the tail of the whole dynamic codebook enhancement for transmission.

As shown in fig. 3, the dynamic codebook enhancement is divided into a first part (i.e., the first part) which is a HARQ-ACK bit sequence corresponding to DCI (i.e., a HARQ-ACK bit sequence corresponding to DCI involving n0 (0 to M) PDSCH packets) and a second part (i.e., the second part) which is a HARQ-ACK bit sequence corresponding to SPS PDSCH (i.e., a HARQ-ACK bit sequence corresponding to SPS PDSCH involving n1 (0 to M) PDSCH packets). Where M is the maximum number of PDSCH packets that is assumed to be allowed or configurable. It should be understood that in fig. 3, the dashed line box indicates the relative position relationship between the corresponding bit sequence and other bit sequences when the bit sequence exists, and in actual transmission, the HARQ-ACK bit sequence corresponding to DCI or SPS PDSCH is not always transmitted for a certain PDSCH packet. In other words, for a certain PDSCH packet, the HARQ-ACK bit sequence corresponding to the DCI and/or the HARQ-ACK bit sequence corresponding to the SPS PDSCH may be included, and there may be no HARQ-ACK bit sequence corresponding thereto. The following detailed description is for the case where the first and second portions do not necessarily exist simultaneously:

case 1: when SPS PDSCH HARQ-ACK is transmitted alone, i.e. only the second part (n0 ═ 0, n1>0) is transmitted in fig. 3, the following can be done:

case 1-1: when only SPS PDSCH HARQ-ACK for a single PDSCH packet is involved (i.e., n1 ═ 1), only the SPS PDSCH HARQ-ACK bit sequence for this PDSCH packet is transmitted.

Cases 1-2: when SPS PDSCH HARQ-ACK (i.e., n1>1) of more than one PDSCH packet is involved, the SPS PDSCH HARQ-ACK bit sequences of the PDSCH packets are concatenated in a predefined order to obtain the SPS PDSCH HARQ-ACK bit sequence to be transmitted. The predefined order may be an increasing order based on the group number of the PDSCH packets.

Case 2: when SPS PDSCH HARQ-ACK is transmitted together with other DCI-based HARQ-ACK, i.e. the first and second parts are transmitted simultaneously in FIG. 3 (n0>0, n1> 0; a certain PDSCH packet involved in dynamic codebook enhancement does not necessarily contain both HARQ-ACK bit sequence corresponding to DCI and HARQ-ACK bit sequence corresponding to SPS PDSCH), the following may be done:

the SPS PDSCH HARQ-ACK bit sequence to be transmitted is obtained and transmitted after being appended to the dynamic codebook enhancement determined based on the DCI as processed in case 1-1 or case 1-2.

Alternatively, the determination of SPS PDSCH HARQ-ACK bit sequence of a PDSCH packet, or the determination of SPS PDSCH HARQ-ACK bit sequence of a PDSCH packet for a serving cell when multiple serving cells are configured, may be performed in some manner as follows:

mode 1: only HARQ-ACKs corresponding to SPS PDSCHs with HARQ-ACK feedback slots coinciding with codebook transmission slots are considered.

Mode 2: considering starting from the last NFI flip of the PDSCH packet to which the SPS PDSCH belongs (for example, taking the system time when the NFI flip of the PDSCH packet to which the SPS PDSCH belongs is the last NFI flip as a reference time, and taking the SPS PDSCH whose start time is after the reference time and belonging to the PDSCH packet into a feedback range), until all HARQ-ACKs corresponding to the SPS PDSCH within a specified end time are reached. For these SPS PDSCHs, their corresponding NFI may be considered to be the NFI value after the last NFI flip.

Wherein, the specified ending time can adopt a certain mode as follows:

the HARQ-ACK feedback time slot corresponding to the latest SPS PDSCH (namely the HARQ-ACK feedback time slot n + k determined based on the time slot n where the SPS PDSCH is transmitted and the HARQ-ACK feedback time slot offset k) is not later than the dynamic codebook transmission time slot;

and the time interval between the ending time of the latest SPS PDSCH and the starting time of the PUCCH or PUSCH transmitted by the dynamic codebook is not less than a preset value. The preset value may be determined by the capability of the terminal, may also be a protocol agreement, and may also be a network device configuration, which is not further limited herein.

The last NFI inversion of the PDSCH packet to which the SPS PDSCH belongs may be determined by the following manner a or manner a + manner b:

the method a: NFI determination based on DCI explicit indication in this PDSCH packet. In particular, the determination may be based on the NFI (e.g., indicated in the non-fallback DCI scheduling the PDSCH transmission of the PDSCH packet) that was explicitly indicated most recently by the PDSCH packet. Here, nearest may be understood as being nearest in time to the dynamic codebook transmission slot.

Mode b: based on other predefined rules (e.g., a certain dynamic codebook transmission corresponds to only fallback DCI scheduled PDSCH transmissions or indicated SPS PDSCH releases for a certain PDSCH packet, assuming that the NFI of this PDSCH packet is flipped from the first of these fallback DCIs).

Optionally, for any of the above manners (i.e. manner 1 or manner 2), it is assumed that the SPS PDSCH requiring HARQ-ACK feedback belongs to one or more downlink SPS configurations, and each downlink SPS configuration corresponds to one configuration index, and the configuration index can uniquely identify the downlink SPS configuration within the active BWP range of a single serving cell. The determination of the SPS PDSCH HARQ-ACK bit sequence for a single serving cell at this time may employ the following operations:

mode I: the transmission time of the SPS PDSCH with a single downlink SPS configuration included in the feedback range is traversed (typically, the transmission time may be arranged from front to back according to the SPS PDSCH transmission time), and then the downlink SPS configurations are traversed (typically, the transmission time may be arranged from small to large according to the downlink SPS configuration index).

Mode II: the downlink SPS configurations (which may exist) in a certain transmission time slot are traversed (typically, they may be arranged from small to large according to the downlink SPS configuration index), and then the transmission time slots are traversed (only the time slot in which the SPS PDSCH transmission exists and whose HARQ-ACK needs to be fed back in the dynamic codebook is taken as the transmission time slot for traversal; typically, the time slots may be ordered from large to small according to the time interval between the transmission time slot and the transmission time slot of the dynamic codebook).

Mode III: directly traversing the transmission start time of the SPS PDSCH, without distinguishing which downlink SPS configuration each SPS PDSCH specifically corresponds to, it is assumed here that for an active BWP of a single serving cell (there is only a single BWP in active state for a single serving cell at any time), there is no time-domain overlap in the durations of any two SPS PDSCH transmissions.

It should be noted that, when a PDSCH packet relates to HARQ-ACK requiring feedback corresponding to SPS PDSCHs on multiple serving cells, SPS PDSCH HARQ-ACK bit sequences corresponding to each serving cell are determined according to the above operations, then SPS PDSCH HARQ-ACK bit sequences corresponding to each serving cell are sequentially concatenated according to serving cell indexes, and the concatenated HARQ-ACK bit sequences are transmitted according to case 1 or case 2. Here, the concatenation is performed in order according to the serving cell index, and may be performed in an ascending order based on the serving cell index.

Scheme II: the HARQ-ACK bit corresponding to the SPS PDSCH is always appended to the tail of the dynamic codebook corresponding to the PDSCH packet to which the bit is attached (the dynamic codebook may be understood as the bit sequence corresponding to the PDSCH packet, and is not the codebook defined by actual transmission).

As shown in FIG. 4, the dashed boxes indicate that when there is a corresponding bit sequence, the bit sequence is associated with other bit sequencesThe relative positional relationship of the bit sequence is not always such that, in actual transmission, the HARQ-ACK bit sequence corresponding to DCI or SPS PDSCH is not always transmitted for a certain PDSCH packet. In other words, for a certain PDSCH packet, the HARQ-ACK bit sequence corresponding to the DCI and/or the HARQ-ACK bit sequence corresponding to the SPS PDSCH may be included, and there may be no HARQ-ACK bit sequence corresponding thereto. Dynamic codebook enhancement corresponding HARQ-ACK bit sequence containing n (n)>0) HARQ-ACK bit sequences corresponding to the PDSCH packets. For convenience of description, assume that M is the maximum number of allowed or configurable PDSCH packets, M is the index or group number of each PDSCH packet, M is the number of PDSCH packets>0 and m<(M-1). For PDSCH packet m, g (m,0) and g (m,1) are used to respectively indicate whether the HARQ-ACK bit sequence corresponding to DCI and the HARQ-ACK bit sequence corresponding to SPS PDSCH of the PDSCH packet are included in the dynamic codebook enhancement of the final transmission, g (m,0) and g (m,1) are both taken as 0 or 1, g (m) is the logical or of g (m,0) and g (m,1) to indicate whether the HARQ-ACK bit sequence corresponding to PDSCH packet m is included in the dynamic codebook enhancement of the final transmission, g (m) ═ 0 indicates that it is not included, and g (m) ═ 1 indicates that it is included. Then in the context of figure 4,

when SPS PDSCH HARQ-ACK is transmitted alone (i.e., n0 ═ 0, n1>0), it is identical to the SPS PDSCH HARQ-ACK bit sequence transmitted and operated in case 1 in scheme one.

When SPS PDSCH HARQ-ACK is transmitted together with other DCI-based HARQ-ACK (i.e. n0>0, n1>0), the following operations are sequentially performed:

the first step is as follows: and performing corresponding operation in the first scheme, and determining SPS PDSCH HARQ-ACK bit sequences corresponding to the PDSCH packets needing to feed back the HARQ-ACK.

The second step is that: determining the HARQ-ACK bit sequence corresponding to each PDSCH packet can distinguish the following cases:

when a certain PDSCH packet only needs to feed back HARQ-ACK corresponding to the SPS PDSCH, the HARQ-ACK bit sequence corresponding to the PDSCH packet is the SPS PDSCH HARQ-ACK bit sequence corresponding to the PDSCH packet.

When a PDSCH packet needs to simultaneously feed back HARQ-ACK corresponding to the SPS and other DCI-based HARQ-ACK, SPS PDSCH HARQ-ACK bit sequences corresponding to the PDSCH packet are concatenated bit by bit after the DCI-based determined HARQ-ACK bit sequences.

It should be further noted that, in the above transmission scheme of HARQ-ACK corresponding to SPS PDSCH, how to organize the dynamic codebook (i.e. the finally transmitted HARQ-ACK bit sequence) is considered from the HARQ-ACK range or situation that needs to be finally carried on a certain PUCCH or codebook transmission. The following simple analysis leads to the aforementioned scenarios of various HARQ-ACK bearer ranges or scenarios.

Scenarios requiring the transmission of SPS PDSCH HARQ-ACK corresponding to a certain PDSCH packet include:

case a: the HARQ-ACK of the SPS PDSCH is transmitted in its corresponding feedback slot. Here, the following three transmission cases can be further distinguished:

case a-1: SPS PDSCH HARQ-ACK is transmitted separately within the feedback slot and does not refer to the transmission of other HARQ-ACKs corresponding to DCI within the same PDSCH packet (corresponding to rule 1 below).

Case a-2: SPS PDSCH HARQ-ACK is transmitted separately in the feedback slot and triggers retransmission of HARQ-ACK corresponding to other DCI in the same PDSCH packet based on some rule (corresponding to rule 2 below). When there is no HARQ-ACK feedback slot corresponding to any DCI coinciding with the SPS PDSCH HARQ-ACK feedback slot (corresponding to HARQ-ACK initial transmission when coinciding), for the same PDSCH packet, the following certain rule is applied:

rule 1: HARQ-ACK feedback of SPS PDSCH of a PDSCH group does not always trigger retransmission of HARQ-ACK corresponding to other DCI of the PDSCH group.

Rule 2: when the parameter SPS-PUCCH-AN-List is configured for the UE, the HARQ-ACK feedback of the SPS PDSCH of a certain PDSCH group can trigger the retransmission of the HARQ-ACK corresponding to other DCI of the PDSCH group; and selecting a certain PUCCH resource in the PUCCH resource List corresponding to the parameter SPS-PUCCH-AN-List according to the number of the HARQ-ACK bits to be transmitted.

Case a-3: SPS PDSCH HARQ-ACK is transmitted in the feedback time slot, and other HARQ-ACK corresponding to the DCI in the same PDSCH packet also corresponds to the feedback time slot (the corresponding HARQ-ACK feedback time slot is determined by the 'PDSCH-to-HARQ _ feedback indicator' indication field in the DCI).

Case b: when the HARQ-ACK corresponding to the DCI of the PDSCH packet to which the SPS PDSCH belongs is transmitted (including the initial transmission and the triggering retransmission), SPS PDSCH HARQ-ACK is piggybacked.

It should be understood that the above case a-1 may be understood as the terminal performing the operation in step 203, the above cases a-2 and a-3 may be understood as the terminal performing the operation in step 204, and the above case b may be understood as the terminal performing the operation in step 205.

The above cases a-2, a-3 and b finally result in SPS PDSCH HARQ-ACK being transmitted with other DCI-based HARQ-ACK for a certain PDSCH packet, and case a-1 transmitting only SPS PDSCH HARQ-ACK for a certain PDSCH packet.

If only SPS PDSCH HARQ-ACK is transmitted for all PDSCH packets (single or multiple PDSCH packets) involved in a certain dynamic codebook enhancement transmission, then case 1 above is corresponded; the aforementioned case 2 is corresponded as long as there is SPS PDSCH HARQ-ACK of at least one PDSCH packet transmitted together with other DCI based HARQ-ACKs.
