And feeding back the feedback information of the PDSCH in one of the N codebooks, and filling the feedback bit corresponding to the PDSCH in the rest N-1 codebooks with a negative acknowledgement NACK. In this way, the network device can acquire the codebook including the real feedback information and can determine the codebook including the padding information, thereby avoiding inconsistency of the feedback information determined by the network device and the terminal device and ensuring the reliability of transmission. And the padding information is known information and can be used for CRC (cyclic redundancy check) of the rest N-1 codebooks, so that the reliability of feedback information transmission in the codebook where the padding information is located is further improved.

Detailed Description

The embodiments of the present application will be described below with reference to the drawings.

The Radio Access Network (RAN) and RAN 1 working group of the third Generation Partnership Project (3 GPP) define the performance indicators of the UR LL C service as follows.

The transmission time required for a user application layer data packet to reach a wireless protocol stack layer 2/3SDU (discontinuous reception) at a receiving end from a Service Data Unit (SDU) of a wireless protocol stack layer 2/3 at a transmitting end, UR LL C service requires 0.5ms for uplink and downlink user plane time delay, but is only applicable to Discontinuous Reception (DRX) when neither the transmitting end nor the receiving end is in a discontinuous reception state, and the time delay is average time delay and is not bound with the following reliability requirement.

The reliability is that the success probability of transmitting X-bit data to the receiving end by the transmitting end within a certain time is still defined as the time required by a user application layer data packet to reach a wireless protocol stack layer 2/3SDU of the receiving end from a wireless protocol stack layer 2/3SDU of the transmitting end, for UR LL C service, the reliability of transmitting 32bytes data within 1ms is generally required to reach 99.999%.

System capacity: the maximum throughput of the cell that can be achieved by the system on the premise of satisfying a certain proportion of the interrupt users, wherein the interrupt users can be users who cannot satisfy the reliability requirement within a certain time delay range.

Codebook: the codebook in this application refers to a hybrid automatic repeat request (HARQ) codebook, and specifically refers to information bits formed by concatenating feedback information bits of all downlink data channels PDSCH.

Slot (slot): in a time domain unit of data scheduling, under a normal cyclic prefix, one slot has 14 symbols, and under an extended cyclic prefix, one slot has 12 symbols.

The symbol in the embodiment of the present application may also be referred to as a time domain symbol, where the time domain symbol may be an Orthogonal Frequency Division Multiplexing (OFDM) symbol, or may also be a discrete fourier transform spread orthogonal frequency division multiplexing (DFTS-OFDM) symbol.

Downlink Control Information (DCI): the method is mainly used for scheduling the downlink data channel PDSCH. The scheduling PDSCH means that the DCI includes information required for receiving the PDSCH, for example: time domain information, frequency domain information, modulation coding mode information, and the like.

Time domain interval: the method is to divide 14 symbols or 12 symbols of a slot into a plurality of intervals, and each interval is a time domain interval. For example, 14 symbols of a slot are divided into 2 time domain intervals, where the first 7 symbols of the slot are the first time domain interval, and the last 7 symbols of the slot are two time domain intervals. For another example, 14 symbols of a timeslot can be divided into 3 time domain intervals, wherein 1 st to 4 th symbols are a first time domain interval, 5th to 8 th symbols are a second time domain interval, 9 th to 12 th symbols are a third time domain interval, and 13 th to 14 th symbols are a fourth time domain interval.

As shown in fig. 1, fig. 1 is an architectural diagram of a communication system 100 provided in this embodiment, the communication system 100 may include a network device 110 and terminal devices 101 to 106, it should be understood that the communication system 100 to which the method of this embodiment may be applied may include more or less network devices or terminal devices, the network devices or terminal devices may be hardware, functionally partitioned software, or a combination of the above, the network devices and the terminal devices may communicate with each other through other devices or network elements, in the communication system 100, the network device 110 may transmit downlink data to the terminal devices 101 to 106, of course, the terminal devices 101 to the terminal devices 106 may transmit uplink data to the network device 110, the terminal devices 101 to the terminal devices 106 may be cellular phones, smart phones, portable computers, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, Personal Digital Assistants (PDAs), and/or any other suitable terminal devices for communicating on the wireless communication system 100, the internet of mobile devices 100 may transmit downlink data to the network devices 104 or other devices through internet network devices 104, or the internet network devices may also transmit uplink data to the network devices 104 to the internet network system 100.

Based on the communication system 100, after receiving downlink data carried in the PDSCH sent by the network device, the terminal device sends feedback information to the network device according to a decoding result of the downlink data. The generation of the feedback information mainly comprises the following steps:

1001. a feedback time unit is determined.

The feedback information may be a HARQ response message, that is: an Acknowledgement (ACK) of data reception or a Negative Acknowledgement (NACK) of data reception. And the timing relation of n + k1 is satisfied between the downlink data received from the terminal equipment and the ACK/NACK fed back to the network equipment by the terminal equipment. Wherein n represents a time unit for receiving downlink data PDSCH, K1 represents a time unit of a difference between a time unit for receiving PDSCH and a time unit for corresponding ACK/NACK feedback, and K1 is indicated by DCI. The time unit may be a slot (slot). For example, as shown in FIG. 2, FIG. 2 is a schematic diagram of a time cell. And the terminal equipment receives the downlink data in the nth slot, and if K1 is 4, the terminal equipment feeds back ACK/NACK to the network equipment in the (n + 4) th slot. I.e. the determined feedback time unit is the (n + 4) th slot.

1002. And generating the HARQ _ ACK codebook in a feedback time unit.

If it is determined that feedback information is to be sent in the (n + 4) th slot, assuming that the (n + 4) th slot is the ith slot, and we mark it as slot, the terminal device generates a HARQ _ ACK codebook in the slot i according to all ACKs and NACKs that need to be fed back. In different codebook modes, the generation modes of generating one HARQ _ ACK codebook in one slot are different, and the generation modes of codebooks in various codebook modes include:

(1) semi-static codebook mode

For the HARQ _ ACK Codebook generation method in the semi-static Codebook mode (also called Type 1HARQ Codebook), the terminal device first determines a K1 set, where the K1 set includes multiple K1 values. And then, according to a K1 set, the method is pushed forward from slot i, and all slots where downlink data PDSCHs which may send feedback information at slot i are located are determined. For example, the set of K1 is determined to be {0, 1, 2, 3, 4 }. As shown in fig. 3, starting from the ith slot, according to the K1 set, it can be determined that the PDSCH in (i-4), (i-3), (i-2), (i-1) and (i) slots are all possible to feed back ACK/NACK in slot i. If a piece of DCI is received in the (i-4), (i-3), (i-2), (i-1) and (i) slots, the DCI indicates K1, and it is determined according to the K1 that the data scheduled by the DCI needs to be fed back in slot i, then all the feedback information of PDSCH candidate occasions (candidate occasions) in the (i-4), (i-3), (i-2), (i-1) and (i) slots needs to be fed back in slot i, if some PDSCH candidate occasions in the slots do not receive PDSCH, the feedback bit corresponding to the PDSCH candidate occasion fills NACK, and if PDSCH is received in a PDSCH candidate occasion, the feedback information of the received PDSCH is fed back on the feedback bit corresponding to the PDSCH occasion. The PDSCH candidate timing determination method and the codebook generation method are as follows.

In the determined (i-4), (i-3), (i-2), (i-1) and (i) slots, each slot determines a PDSCH candidate timing (candidate timing) according to the following manner, specifically, the terminal device first receives configuration information sent by the network device through high-layer signaling, where the configuration information is a time domain resource table, where the table includes at most 16 rows, each row indicates a starting symbol S of a time domain resource that may be occupied by a PDSCH and a symbol number L, S indicates a position of the starting time domain symbol of the time domain resource in one slot, L indicates a number of time domain symbols occupied by the time domain resource in one slot from the starting symbol S.

For example, as shown in fig. 3, fig. 3 is a schematic diagram of PDSCH candidate registration determination in a semi-static codebook mode. If the terminal device receives configuration information sent by the network device through the high-level signaling, the configuration information is a time domain resource table, the table includes 16 rows, each row indicates a time domain resource that may be occupied by a PDSCH, 16 time domain resources respectively correspond to time domain resources #0 to #15 in fig. 3, the 16 time domain resources are split, and the splitting position is shown by a dotted line in fig. 3. The first segmentation position is the end position of the time domain resource which is closest to the end symbol on the time domain, namely the end position of the time domain resource #12, and the resources cut by the segmentation position are determined, namely the time domain resources #0, #1, #2, #3, #4, #6, wherein the time domain resources { #0, #1, #2, #3, #4, #6, #12} correspond to a PDSCH candidate time; then, determining a second segmentation position from the remaining time domain resources, namely { #5, #7, #8, #9, #10, #11, #13, #14, #15} as the end position of the time domain resource with the most front end symbol in the time domain resources, namely the end positions of #13 and #9 time domain resources, and segmenting according to the segmentation position to obtain a second PDSCH candidate time, wherein the second PDSCH candidate time corresponds to time domain resources { #7, #9, #13 }; the aforementioned method can obtain 4 PDSCH candidate occases, which respectively include time domain resources { #0, #1, #2, #3, #4, #6, #12, { #7, #9, #13, { #5, #8, #10, #14, { #11, #15} corresponding to the numbers in the small brackets in fig. 3.

After determining the PDSCH candidate timing in each slot, the total bit number of the feedback information of each slot may be determined, where the total bit number of the feedback information of each slot is the sum of the feedback bit numbers corresponding to each PDSCH candidate timing in the slot. The feedback bit corresponding to each PDSCH candidate occasion may be an H bit, specifically, the corresponding H may be a numerical value configured by a higher layer signaling, or H is 1, which is not limited herein, and it is described that the feedback bit H is 1. Specifically, the determined PDSCH candidate occasions correspond to H feedback bits respectively in the order of time domain positions from front to back. Each pdschhcandidate occuration is associated with one or more time domain resources with overlapped time domains, only 1 PDSCH is allowed to be transmitted on the time domain resources with overlapped time domains at most, the PDSCH corresponds to feedback information with H bits, and the feedback bit corresponding to the PDSCH is the feedback bit corresponding to the PDSCH candidate time at which the PDSCH is located.

For example, assuming that H is 1 for 4 PDSCH candidate occasions as shown in fig. 3, that is, the number of feedback bits corresponding to the PDSCH candidate occasions is 1 bit, the total number of bits of the feedback information in each slot is 4 bits. The PDSCH timing candidate (1), i.e. the timing candidate corresponding to the time domain resources { #0, #1, #2, #3, #4, #6, #12} is the first in the time domain, and the feedback bit corresponding to the PDSCH timing candidate is the first bit of the feedback information of the slot. That is, PDSCH candidate occasions (1) - (4) correspond to bits 1-4 of the slot feedback information, respectively. If H is 2, the PDSCH candidate occasion (2) corresponds to the first 2 bits. And will not be described in detail. In time domain resources { #0, #1, #2, #3, #4, #6, #12} associated with the PDSCH candidate timing (1), assuming that the PDSCH is received on time domain resource #2, the feedback information of the PDSCH is on the 2 nd bit in the slot feedback information.

And (3) connecting a plurality of downlink slots associated with the uplink slot i, for example, the feedback information in all the slots in the (i-4), (i-3), (i-2), (i-1) and (i) slots in series from front to back according to the time domain position, wherein each PDSCCHcandidate event corresponds to the feedback information of itself to form a final HARQ-ACK codebook.

(2) Dynamic codebook mode

For the HARQ _ ACK Codebook generation method in the dynamic Codebook mode (also called Type 2HARQ Codebook), if the terminal device receives the DCI, the DCI indicates K1, and it is determined according to the K1 that the PDSCH scheduled by the DCI is to be fed back in slot i, the HARQ _ ACK Codebook of slot i contains the feedback information of the data scheduled by the PDCCH, or contains the feedback information of the PDSCH release of semi-persistent scheduling (SPS) indicated by the PDCCH.

1003. Physical Uplink Control Channel (PUCCH) resources are determined.

After the HARQ-ACK codebook is determined, the terminal device first determines the number of bits that need to feed back the codebook, i.e. the load size (payload size), and then selects a PUCCH resource set (resource set) according to the payload size. Each PUCCH resource set contains at least 8 PUCCH resources and at most 32 PUCCH resources. Further, the terminal device may determine which resource of the selected set the PUCCH resource feeding back the ACK/NACK codebook is based on the received ACK/NACK resource indicator (ARI) byte and implicit indication in the last 1 PDCCH that the scheduling ACK/NACK belongs to the codebook. Transmitting the codebook on the PUCCH resource.

The PUCCH resource sets are configured by the network device through high-layer signaling.

For example, as shown in fig. 4, when receiving the PDSCH of the eMBB service in the 1 st slot and scheduling the DCI indication K1 of the PDSCH is 2, feedback information corresponding to the PDSCH should be fed back in the 3rd slot, when receiving the PDSCH of the UR LL C service in the 2 nd slot and scheduling the DCI indication K1 of the PDSCH is 1, feedback information corresponding to the PDSCH is fed back in the 3rd slot, the feedback information of both PDSCHs should be fed back in the 3rd slot, according to the description of the aforementioned semi-static codebook mode and dynamic codebook mode, the terminal device uniformly generates one HARQ feedback resource for the eMBB service and the feedback information for the UR LL C service in the 3rd slot, and then determines the final HARQ feedback resource according to the DCI indication K LL of the second slot, i.e., the DCI indication K LL.

The UR LL C service has higher requirement on time delay and higher requirement on reliability, so that more PUCCH resources are transmitted for the feedback information of the PDSCH corresponding to the UR LL C service, so that the reliability of the PUCCH is ensured by reducing the code rate.

For example, when the dynamic codebook mode is used, the method for generating a plurality of HARQ codebooks in one slot may include the following:

the first mode is as follows: by dividing an uplink time slot into a plurality of time domain intervals, generating a HARQ _ ACK codebook in each time domain interval, if a PUCCH resource corresponding to a PDSCH is in a certain time domain interval (a starting symbol or an ending symbol of the PUCCH is in a certain time domain interval), feedback information corresponding to the data is contained in the HARQ _ ACK codebook of the time domain interval for feedback. Specifically, the terminal device receives physical downlink control information DCI, where the DCI indicates K1, determines that the PDSCH scheduled by the DCI is to be fed back at slot i according to the K1, determines a PUCCH resource corresponding to the PDSCH according to the foregoing step 1003, and then determines a codebook corresponding to the PDSCH feedback information according to the time domain interval in which the PUCCH resource is located.

For example, as shown in fig. 5, one large lattice represents one slot, and one slot of an upper row is divided into 2 time domain sections. The first PDSCH1 is received in slot i-2, DCI1 scheduling the PDSCH1 indicates that K1 is 2, i.e., ACK/NACK is fed back after 2 slots, i.e., slot i, and DCI1 also indicates the corresponding PUCCH1 resource. A second PDSCH2 is received in slot i-1, the DCI2 scheduling the PDSCH2 indicates that K1 is 1, that is, after 1 slot, the slot i feeds back ACK/NACK, and the DCI2 further indicates the corresponding PUCCH2 resource. Since the end symbol of the PUCCH1 is in the second time domain interval of slot i and the end symbol of the PUCCH2 is in the first time domain interval, the feedback information of the PDSCH1 is fed back in the second HARQ _ ACK codebook of slot i, and the feedback information corresponding to the PDSCH2 is fed back in the first HARQ _ ACK codebook of slot i.

In the second method, a HARQ _ ACK codebook is generated for each group by grouping PDSCHs. For example, in fig. 5, the first PDSCH1 is received in slot i-2, DCI1 scheduling the PDSCH1 indicates that K1 is 2, that is, ACK/NACK is fed back after 2 slots, i.e., slot i, and the second PDSCH2 is received in slot i-1, and DCI2 scheduling the PDSCH2 indicates that K1 is 1, that is, ACK/NACK is fed back after 1 slot i. If PDSCH1 and PDSCH2 belong to the same group, the feedback information of both are included in one HARQ _ ACK codebook, and if they belong to different groups, the feedback information of both are included in different HARQ _ ACK codebooks.

The specific grouping may be according to any of the following: a DCI format of the scheduled PDSCH, a scrambling scheme RNTI of the DCI of the scheduled PDSCH, a length of the PDSCH, or a mapping type of the PDSCH, etc., which is not limited in the present application.

For example, the DCI format scheduling PDSCH may be divided into N groups, each group generating one codebook. Assuming that the DCI format of the scheduled PDSCH generates one codebook for DCI format1, the DCI format of the scheduled PDSCH generates one codebook for DCI format 2, … …, and the DCI format of the scheduled PDSCH generates one codebook for DCI format N, that is, N codebooks are generated for N DCI formats. Or, the number of DCI formats in each group of the N groups of DCIs is not unique. If the DCI1 scheduling the PDSCH1 belongs to the f-th group of the N-th group of DCIs, the feedback information of the PDSCH is included in the codebook corresponding to the f-th group of DCI.

For another example: DCI scrambling RNTIs for scheduling PDSCH may be divided into N groups, each group generating one codebook. Assume that DCI scrambled RNTI of a scheduled PDSCH is a codebook generated by RNTI1, DCI scrambled RNTI of a scheduled PDSCH is a codebook generated by RNTI2, … …, and DCI scrambled RNTI of a scheduled PDSCH is a codebook generated by RNTIN, that is, N codebooks are generated by N DCI scrambled RNTIs. Or, the DCI scrambling RNTI in each of the N groups of DCIs is not unique. If the scrambled RNTI1 of the DCI1 scheduling the PDSCH1 belongs to the f-th group of the N-group DCI, the feedback information of the PDSCH is contained in the codebook corresponding to the scrambled RNTI of the f-th group DCI.

For the semi-static codebook mode, the method for generating multiple HARQ codebooks in one slot may include the following steps:

in the first method, an uplink slot is divided into a plurality of time domain intervals, and each time domain interval corresponds to one HARQ _ ACK codebook, so that a plurality of HARQ _ ACK codebooks are generated in one slot. The terminal device determines the time unit for feedback first, for example, the time unit for feedback is determined by adopting the manner in step 1001, and the uplink timeslot is determined to be slot i. Then, the generating manner of each codebook in the plurality of codebooks in slot i may refer to the manner of generating the HARQ _ ACK codebook described in the generating step 1002 of the aforementioned feedback information. Because the plurality of HARQ _ ACK codebooks are generated in one slot, a plurality of identical HARQ _ ACK codebooks are generated in one slot according to the manner of generating codebooks described above.

In the second method, a PDSCH transmitting feedback information in one uplink slot is grouped, and one HARQ _ ACK codebook is generated for each group. And (3) determining a feedback time unit, determining the feedback time unit by adopting the step 1001, and determining the uplink time slot as slot i. The generation manner of each of the plurality of codebooks in slot i may be generated in the manner referred to in the foregoing step 1002. Because the plurality of HARQ _ ACK codebooks are generated in one slot, a plurality of identical HARQ _ ACK codebooks are generated in one slot according to the manner of generating codebooks described above.

For example, 2HARQ codebooks are generated in one uplink slot, the advance can be started from slot i, and according to the K1 set, assuming that the K1 set is {0, 1, 2, 3}, the slot where data of feedback information may be sent is determined. As shown in FIG. 6, 4 slots are determined, that is, slot i-3, slot i-2, slot i-1, and slot i all transmit feedback information in slot i. According to the description of the manner of generating the codebook according to the semi-static codebook mode, the 2HARQ _ ACK codebooks all need to include the feedback information in the 4 slots. If the decoding results corresponding to the PDSCH1 and the PDSCH2 are correct, the ACK needs to be fed back in all 2HARQ _ ACK codebooks, which may cause a problem of repeated feedback, resulting in waste of uplink resources. If the repeated feedback results are the same, for example, one ACK is repeatedly fed back for 2 times, if an error occurs in one of the transmission processes, one of the feedback information received by the network device is an ACK, and the other is a NACK, it cannot be determined which is correct, which causes inconsistency with the feedback information determined by the terminal device, and reduces reliability of data transmission.

In addition, for the semi-static codebook mode, as long as a piece of DCI is received, a slot where feedback information of the PDSCH scheduled by the DCI can be sent is determined according to the DCI, for example, the slot i. The slot where the data of the feedback information is possibly sent in slot i can be determined according to the K1 set and the K1 set as {0, 1, 2, 3 }. As shown in FIG. 6, 4 slots are determined, that is, slot i-3, slot i-2, slot i-1, and slot i all transmit feedback information in slot i. If only one PDSCH is received in the 4 slots, slot i is also required to transmit a HARQ _ ACK codebook, which contains feedback information corresponding to all PDSCH candidate occasions within the 4 slots, and if there is no data scheduling in a certain slot, NACK is filled. If there is only one data scheduling in 4 slots and feedback information of PDSCH candidate occasions of multiple slots needs to be sent, for example, 4 slots, each PDSCH occasion of each slot corresponds to feedback information of H bits, which also results in waste of uplink resources. In order to solve the above technical problem, embodiments of the present application provide the following solutions.

Referring to fig. 7, fig. 7 is a flowchart illustrating an information processing method according to an embodiment of the present disclosure. As shown in the figures, the steps in the embodiment of the present application include:

s702, the network device sends downlink control information DCI to the terminal device, wherein the DCI is used for scheduling a Physical Downlink Shared Channel (PDSCH).

Illustratively, the DCI may be carried in the PDCCH.

S704, the terminal equipment receives the DCI and receives the PDSCH according to the DCI.

S706, the terminal device sends N codebooks to the network device in the first time slot.

S708, the network device receives the N codebooks.

The N codebooks include a first codebook and N-1 second codebooks, feedback information of the PDSCH is located at feedback bits corresponding to the PDSCH in the first codebook, padding information is located at feedback bits corresponding to the PDSCH in the second codebooks, and N is an integer greater than or equal to 2.

It should be noted that, only one first codebook is included in the N codebooks, and all codebooks except the first codebook are second codebooks. For example, suppose N is equal to 5, i.e. there are 5 codebooks, there are only 1 first codebook, and the remaining 4 are all second codebooks.

Illustratively, the first time slot may be one time slot, and the first time slot may be indicated by the DCI, and the DCI may include second indication information indicating the first time slot.

For example, the second indication information indicates a value of K1, and the value of K1 is used to indicate the number of slots separated between the slot where the PDSCH scheduled by the DCI is located and the slot where the feedback information of the PDSCH is located (i.e., the first slot). Specifically, as shown in fig. 8, when the PDSCH1 is received at slot i-2 and the DCI1 scheduling the PDSCH1 indicates that K1 is 2, the feedback information of the PDSCH1 is fed back at slot i, that is, the first slot is the ith slot. The PDSCH2 is received at slot i-1 and the DCI2 scheduling the PDSCH2 indicates that K1 is 1, then the feedback information of the PDSCH2 is also fed back at slot i, i.e. the first slot is the ith slot.

The terminal device sends N codebooks to the network device in the first time slot, where the number N of codebooks may be a value agreed in advance by the terminal device and the network device, or may be a value predefined by a protocol, or may be a value indicated by indication information sent by the network device. For example, the protocol specifies that a time slot is divided into N time domain intervals, each interval generates 1 codebook, and then N is the number of time domain intervals, that is, N codebooks are generated in one time slot. For another example, the protocol specifies N groups of DCI formats, or N groups of RNTIs, or mapping types of N groups of PDSCHs, modulation coding schemes of N groups of PDSCHs, and lengths of N groups of PDSCHs, where each group in the N groups corresponds to one codebook, that is, N codebooks are generated in one time slot, and the value of N is the group number. For another example, the network device sends indication information indicating that N is 3, and the indication information may be carried in DCI or in higher layer signaling. The present application is not limited.

Further, the method further includes step S700a, where the network device may send first indication information to the terminal device, where the first indication information is used to indicate the codebook mode. Step S700b the terminal device receives the first indication information.

The higher layer protocol layer may include at least one of a Medium Access Control (MAC) layer, a radio link control (radio link control, R L C) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, a non-access stratum (NAS), and the like.

Illustratively, the codebook mode is a semi-static codebook mode.

Further, the method further comprises: in step S705, the terminal device generates N codebooks.

It should be noted that, for the semi-static codebook mode, the terminal device generates N codebooks in one slot, where N is an integer greater than or equal to 2. The specific N codebooks include a first codebook and N-1 second codebooks. Next, how to determine the first codebook and the second codebook will be described.

For example, the DCI includes third indication information indicating the first codebook of the N codebooks.

For example, the third indication information indicates a value of K1, and the value of K1 is used to indicate the number of slots separated between the slot in which the PDSCH is located and the slot in which the feedback information of the PDSCH is located (i.e., the first slot). The third indication information is also used for indicating PUCCH resources corresponding to the feedback information of the PDSCH in the first slot. And the terminal equipment determines a time domain interval where the PUCCH resource corresponding to the feedback information of the PDSCH is located according to the third indication information, wherein the time domain interval is called a first time domain interval, and since N time domain intervals exist in the first time slot and each time domain interval corresponds to one codebook, the codebook corresponding to the first time domain interval is a first codebook, and the codebooks corresponding to the remaining N-1 time domain intervals are second codebooks.

For example, as shown in fig. 8, the first slot i includes 2 time domain sections, and one codebook may be generated in each time domain section, that is, N is 2. If the third indication information indicates that the PUCCH resource corresponding to the feedback information of the PDSCH is in time domain interval 1 of slot i, it may be determined that the feedback information of the PDSCH is in codebook 1 corresponding to time domain interval 1, that is, the codebook corresponding to time domain interval 1 is the first codebook, and the codebook corresponding to time domain interval 2 is the second codebook. If the third indication information indicates that the PUCCH resource corresponding to the feedback information of the PDSCH is in time domain interval 2 of slot i, it may be determined that the feedback information of the PDSCH is in codebook 2 corresponding to time domain interval 2, that is, the codebook corresponding to time domain interval 1 is the first codebook, and the codebook corresponding to time domain interval 2 is the second codebook.

Optionally, the third indication information may also directly indicate a first codebook of the N codebooks. For example, if N is 2, the third indication information includes 1 bit, and a value of "0" indicates that the first codebook is the first codebook of the N codebooks. A value of "1" indicates that the first codebook is the second of the N codebooks. And the terminal equipment receives the DCI, determines a first codebook according to the third indication information, and selects a codebook except the first codebook from the N codebooks in the first time slot as a second codebook. For another example, if N is 4, the third indication information includes 2 bits, and a value of "00" indicates that the first codebook is the first codebook of the N codebooks. A value of "01" indicates that the first codebook is the second of the N codebooks.

Optionally, the third indication information may also be a DCI format for scheduling a PDSCH, a scrambling scheme RNTI for DCI for scheduling a PDSCH, a length of the PDSCH, a mapping type of the PDSCH, a modulation and coding scheme of the PDSCH, and the like, and after receiving the third indication information, the terminal device may determine one of the N codebooks as the first codebook according to the third indication information. For example, DCI for scheduling a PDSCH is scrambled by RNTI1, the RNTI1 belongs to a first group of N RNTI groups, a codebook corresponding to the RNTI of the first group is a first codebook, and the remaining N-1 codebooks in the N codebooks are a second codebook. For example, the mapping type of the PDSCH is mapping type a, where the mapping type a belongs to a first group of N mapping type groups, then the codebook corresponding to the first group is a first codebook, and the remaining N-1 codebooks of the N codebooks are second codebooks.

Optionally, the feedback bit corresponding to the PDSCH is determined according to the time domain resource occupied by the PDSCH. Specifically, as described in the semi-static codebook mode, the time domain resource occupied by the PDSCH may correspond to one PDSCH candidate occasion in one slot, the PDSCH candidate occasion corresponds to H feedback bits, and the feedback bits corresponding to the PDSCH may be determined according to the PDSCH candidate occasion corresponding to the time domain resource of the PDSCH. The method for determining the feedback bit corresponding to the PDSCH candidate occasion may be as described above, and is not described again.

For example, as shown in fig. 9, a PDSCH1 is received in the i-2 slot, and DCI1 scheduling the PDSCH1 indicates that K1 is 2, then the feedback information of the PDSCH1 is fed back in the i-slot, that is, the first slot is the i-th slot. The PDSCH2 is received in the i-1 slot and the DCI2 scheduling the PDSCH2 indicates that K1 is 1, then the feedback information of the PDSCH2 is also fed back in the i slot, i.e., the first slot is the i slot. The network device then needs to generate 2 codebooks at slot i. Assuming that the K1 set is {0, 1, 2, 3}, the feedback information of all PDSCH candidate occasions in the (i-3), (i-2), (i-1), and (i) slots needs to be fed back at slot i according to the K1 set, where the K1 set is derived from the ith slot, each PDSCH candidate occasion corresponds to a feedback bit, and each slot is a PDSCH candidate occasion. Therefore, each of the 2 codebooks transmitted in slot i contains 4 feedback bits. Wherein, the 1 st feedback bit corresponds to the PDSCH candidate timing of the (i-3) th slot, the 2 nd feedback bit corresponds to the PDSCH candidate timing of the (i-2) th slot, … …, and the 4 th feedback bit corresponds to the PDSCH candidate timing of the ith slot. The time domain resource occupied by the PDSCH1 is in slot i-2, corresponding to the PDSCH candidate occasion in slot i-2, so the feedback bit corresponding to the PDSCH1 is the 2 nd feedback bit in the 4 feedback bits. The time domain resource occupied by the PDSCH2 is in slot i-1 in the time domain resource, and corresponds to the PDSCH candidate time in slot i-1, so the feedback bit corresponding to the PDSCH2 is the 3rd feedback bit in the 4 feedback bits.

The feedback information of the PDSCH is determined according to the decoding result of the PDSCH, when the decoding result of the PDSCH is correct, the feedback information of the PDSCH is ACK, and when the decoding result of the PDSCH is wrong, the feedback information of the PDSCH is NACK. After the network equipment receives the N codebooks, when the feedback information of the PDSCH is ACK, the decoding result of the PDSCH is correct, and when the feedback information of the PDSCH is NACK, the decoding result of the PDSCH is wrong.

The padding information is non-true feedback information, which is known by both the pre-agreed terminal device and the network device, and may be NACK or ACK, which is described herein by taking NACK as an example.

The terminal equipment sends N codebooks to the network equipment in a first time slot, wherein the N codebooks comprise a first codebook and N-1 second codebooks, feedback information of the PDSCH is arranged on feedback bits corresponding to the PDSCH in the first codebook, and filling information is arranged on feedback bits corresponding to the PDSCH in the second codebooks. The network device may receive the N codebooks in the first time slot, and obtain feedback information of the PDSCH from the N codebooks.

For example, as shown in fig. 9, a first PDSCH1 is received in a slot i-2 (i.e., the 2 nd slot) of the downlink, and DCI1 scheduling the PDSCH1 indicates that K1 is 2, that is, feedback information of the PDSCH1 is fed back in the slot i, and the terminal device determines to transmit N2 codebooks in the slot i according to the method described above, where each codebook includes 4 bits, and determines that the first codebook corresponding to the PDSCH1 is codebook 2 and the second codebook is codebook 1 according to the method described above. And determines the feedback bit corresponding to the PDSCH1 to be the 2 nd feedback bit among the 4 bits. If the decoding result of the PDSCH1 is correct, the feedback bit 2 in codebook 2 is ACK, and the feedback bit 2 in codebook 1 is padding NACK. For another example, the second PDSCH2 is received in the slot i-1 (i.e., the third slot) of the downlink, that is, the feedback information of the PDSCH2 is fed back in the slot i, and the terminal device determines to send N-2 codebooks in the slot i according to the foregoing method, where each codebook includes 4 bits, and determines that the first codebook corresponding to the PDSCH2 is the codebook 1 according to the foregoing method, and then the second codebook is the codebook 2. And determines the feedback bit corresponding to the PDSCH1 to be the 3rd feedback bit of the 4 bits. Therefore, when the decoding result of the PDSCH2 is correct, ACK is provided in the 3rd feedback bit in codebook 1, and padding NACK is provided in the 3rd feedback bit in codebook 2. Since the scheduled PDSCH is not received in other slots, i.e., slot i-3, slot i, other feedback bits of codebook 1 and codebook 2 are upper padding information NACK, and finally, the information contained in codebook 1 is NNAN (i.e., NACK, ACK, NACK) and the information contained in codebook 2 is NANN (i.e., NACK, ACK, NACK), assuming that 1 represents ACK and 0 represents NACK, codebook 1 is "0010" and codebook 2 is "0100". Similarly, if 0 indicates ACK and 1 indicates NACK, the codebook is "1101" and the codebook 2 is "1011".

In the embodiment of the application, when a plurality of codebooks are generated in one time slot in a semi-static codebook mode, the terminal device feeds back the received feedback information of the PDSCH in one of the N codebooks, and fills NACK information in the feedback bits corresponding to the PDSCH in the remaining N-1 codebooks. Therefore, after the network device receives the N codebooks, the network device can know which codebook is the real feedback information, and can determine which codebooks are the filling information, so that inconsistency of the feedback information determined by the network device and the terminal device can be avoided, and the reliability of transmission is ensured. And, since the padding information is known information, such as NACK information, it can be used for Cyclic Redundancy Check (CRC) of the remaining N-1 codebooks, thereby further improving the reliability of feedback information transmission in the remaining N-1 codebooks.

After the terminal device generates N codebooks, the PUCCH resource corresponding to each codebook may be determined with reference to the aforementioned step 1003 for each codebook, and then the codebook may be transmitted on the PUCCH resource corresponding to each codebook.

Optionally, in a fallback mode (falback), that is, when the preset format of the DCI is DCI format1_0, or the preset format of the DCI is a DCI format used for performing data scheduling in a random access process, when an indication field value of a Downlink Assignment Indicator (DAI) included in the DCI is 1 and the DCI is received by a primary cell (on the pcell) where the terminal device is located, the first codebook only includes feedback information of the PDSCH scheduled by the DCI, but does not include feedback information of other PDSCHs and any other padding information. The number of bits of the codebook fed back is reduced, so that the overhead of uplink resources is reduced.

For example, as shown in fig. 10, a first PDSCH1 is received in a slot i-2 (i.e., the 2 nd slot) of the downlink, and DCI1 scheduling the PDSCH1 indicates that K1 is 2, that is, feedback information of the PDSCH1 is fed back in the slot i, and the terminal device determines to transmit N2 codebooks in the slot i according to the method described above, and determines that the first codebook corresponding to the PDSCH1 is codebook 2 according to the method described above, and then the second codebook is codebook 1. And the DCI1 is scheduled to be in a preset format DCI format1_0, the indication field value of one piece of downlink assignment indication information DAI included in the DCI1 is 1, and when the DCI1 is received by the primary cell (on the pcell) where the terminal device is located, if the PDSCH1 decoding result is correct, only one bit is included in the codebook 2 and is NACK. For another example, the second PDSCH2 is received in the slot i-1 (i.e., the third slot) of the downlink, that is, the feedback information of the PDSCH2 is fed back in the slot i, and the terminal device determines, according to the foregoing method, that N ═ 2 codebooks are sent in the slot i, and determines, according to the foregoing method, that the first codebook corresponding to the PDSCH2 is codebook 1, and then the second codebook is codebook 2. And the DCI2 is scheduled to be in a preset format DCI format1_0, the indication field value of the DCI2 including one piece of downlink assignment indication information DAI is 1, and when the DCI2 is received by the primary cell (on the pcell) where the terminal device is located, if the PDSCH2 decoding result is correct, only 1 bit is included in the codebook 1 and is ACK. Therefore, the information contained in codebook 1 is ACK and the information contained in codebook 2 is NACK, and if ACK is represented by 1 and NACK is represented by 0, codebook 1 is "1" and codebook 2 is "0". Similarly, if 0 indicates ACK and 1 indicates NACK, the codebook is "0" and the codebook 2 is "1".

It should be noted that a DAI is carried in the DCI, and the DAI is used to indicate a cumulative number of PDSCHs sent by the network device in the current cell at the current time. It can be simply understood that it is the several PDSCHs sent by the network device. The terminal device may determine whether there is a PDSCH loss according to the DCI. For example, a terminal device receives 2 DCIs, the first DCI indicates DAI-1, the second DCI indicates DAI-3, but does not receive a DCI containing DAI-2. The terminal device may determine that one PDSCH is lost.

Referring to fig. 11, fig. 11 is a flowchart illustrating an information processing method according to an embodiment of the present disclosure. As shown in the figures, the steps in the embodiment of the present application include:

s1102, the network equipment sends downlink control information DCI to the terminal equipment, wherein the DCI is used for scheduling a Physical Downlink Shared Channel (PDSCH).

And S1104, the terminal equipment receives the DCI and receives the PDSCH according to the DCI.

S1106, the terminal device sends a codebook to the network device in the first time slot. The codebook includes feedback information of the PDSCH.

S1108, the network device receives the codebook.

Optionally, before S1102, the method further includes S1100, where the terminal device receives first indication information sent by the network device, and the first indication information is used for indicating a codebook mode. After receiving the first indication information, the terminal device may generate different numbers of codebooks in different codebook modes.

The terminal device may further send, to the terminal device, first indication information through a high-layer signaling, where the high-layer signaling may refer to a signaling sent by a high-layer protocol layer, and the high-layer protocol layer is at least one protocol layer above a physical layer, where the high-layer protocol layer may include at least one of a Medium Access Control (MAC) layer, a radio link control (R L C) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Resource Control (RRC) layer, and a non-access stratum (NAS) layer.

It should be noted that the determination method of the first time slot may be determined by using the foregoing determination method, and details are not described herein.

It should be noted that, for the dynamic codebook mode, the terminal device generates N codebooks in one slot, where N is an integer greater than or equal to 2. The specific manner may refer to the above description of generating a plurality of codebooks in the dynamic codebook mode. And will not be described in detail.

It should be noted that, for the semi-static codebook mode, the terminal device may generate one codebook in one slot, and the specific manner is as described in the foregoing description that the semi-static codebook mode generates one codebook in one slot, which is not described again.

For example, as shown in fig. 12, by counting back the uplink slots i, assuming that the K1 is set to {0, 1, 2, 3}, 4 slots are determined, and feedback information of the 4 slots is generated into one codebook, so that feedback information of PDSCH1 and PDSCH2 are in the same codebook. And when the decoding results of the 2 PDSCHs are all correct, the 2 nd feedback bit and the 3rd feedback bit are both ACK. Since there is no scheduling information in other slots, NACK is filled in the 1 st feedback bit and the 4 th feedback bit, and finally the information contained in the codebook is NAAN (i.e., NACK, ACK, NACK), assuming that 1 represents ACK and 0 represents NACK, the codebook is "0110", and in the same way, 0 represents ACK and 1 represents NACK, the codebook is "1001".

In the embodiment of the application, different reliability requirements of different services can be realized by generating a plurality of codebooks in a dynamic codebook mode. In the semi-static codebook mode, only one HARQ codebook is generated, so that the waste of uplink resources can be reduced.

After the terminal device generates the codebooks, the PUCCH resource corresponding to each codebook may be determined with reference to the aforementioned step 1003 for each codebook, and then the codebook may be transmitted on the PUCCH resource corresponding to each codebook.

Referring to fig. 13, fig. 13 is a schematic flowchart illustrating another information processing method according to an embodiment of the present application. As shown in the figures, the steps in the embodiment of the present application include:

s1302, the network device sends downlink control information DCI to the terminal device, where the DCI is used to instruct to release the semi-persistent scheduling physical downlink shared channel PDSCH.

And S1304, the terminal equipment receives the DCI and releases the semi-statically scheduled PDSCH according to the DCI.

S1306, the terminal device sends N codebooks to the network device in the first timeslot.

S1308, the network device receives the N codebooks.

The specific process may refer to the process in S708, and only the PDSCH feedback information needs to be replaced by the released semi-persistent scheduling PDSCH reasonably, which is not described again.

Further, the method further comprises: in step 1305, the terminal device generates N codebooks.

The specific generation process of the N codebooks may refer to the process in step S705, and only the PDSCH feedback information needs to be replaced reasonably by the released semi-persistent scheduling PDSCH, which is not described again.

The semi-static scheduling of the PDSCH means that a PDSCH transmission period is configured through semi-static signaling, then DCI is transmitted to trigger PDSCH transmission, and PDSCH reception is performed in the period after triggering. If the network device is to stop the semi-statically scheduled PDSCH, a DCI is sent, where the DCI indicates to release the semi-statically scheduled PDSCH, that is, PDSCH reception is no longer performed in the period, or the semi-statically scheduled PDSCH is no longer valid unless triggered again.

The N codebooks comprise a first codebook and N-1 second codebooks, feedback information of the released semi-persistent scheduling PDSCH is arranged on feedback bits corresponding to the released semi-persistent scheduling PDSCH in the first codebook, padding information is arranged on feedback bits corresponding to the released semi-persistent scheduling PDSCH in the second codebooks, and N is an integer greater than or equal to 2.

The feedback information of the released semi-persistent scheduling PDSCH is determined according to the execution result of the released semi-persistent scheduling PDSCH, when the execution result of the released semi-persistent scheduling PDSCH is successful, the feedback information of the released semi-persistent scheduling PDSCH is ACK, and when the execution result of the released semi-persistent scheduling PDSCH is failure, the feedback information of the released semi-persistent scheduling PDSCH is NACK. The padding information is non-true feedback information, which may be NACK or ACK, and this application is described as an example of NACK.

Referring to fig. 14, fig. 14 is a schematic flowchart of another information processing method according to an embodiment of the present application. As shown in the figures, the steps in the embodiment of the present application include:

s1402, the network device sends downlink control information DCI to the terminal device, wherein the DCI is used for indicating to release the physical downlink shared channel PDSCH of the semi-static scheduling.

And S1404, the terminal equipment receives the DCI and releases the semi-statically scheduled PDSCH according to the DCI.

S1406, the terminal device sends the codebook to the network device in the first time slot. The codebook includes feedback information of the released semi-persistent scheduled PDSCH.

S1408, the network device receives the codebook.

Optionally, before S1402, the method further includes S1400, where the terminal device receives first indication information sent by the network device, and the first indication information is used for indicating a codebook mode. After receiving the first indication information, the terminal device may generate different numbers of codebooks in different codebook modes.

When the codebook mode is the dynamic codebook mode, the terminal device may send N codebooks in one slot, where N is an integer greater than or equal to 2. The specific manner may refer to the above description of generating a plurality of codebooks in the dynamic codebook mode. And will not be described in detail.

When the codebook mode is the semi-static codebook mode, the terminal device may send 1 codebook in one slot, where the codebook includes the feedback information of the PDSCH. The specific manner is as described above in the introduction of generating a codebook in a time slot in the semi-static codebook mode, and is not described again.
