Description

[0001] This application is a divisional application of the patent application with the application number 202011043432.2 (the application date of the original application is September 28, 2020, and the invention name is Feedback Codebook Generation, Reception Method, Communication Node and Storage Medium). Technical Field

[0002] This application relates to a wireless communication network, and for example, relates to a method, apparatus, communication node and storage medium for generating and receiving a feedback codebook. Background Art

[0003] In a Hybrid Automatic Repeat reQuest (HARQ) mechanism, the receiving end of data can feedback an Acknowledge (ACK) or Negative Acknowledgement (NACK) message for the received data to the sending end to request the sending end to retransmit the data that fails to be transmitted. Taking the communication between a Base Station (BS) and a User Equipment (UE) as an example, the BS supports two configuration modes for enabling and disabling HARQ processes. For a disabled HARQ process, the BS does not support retransmitting the data that the UE fails to receive at the physical layer. In this case, theoretically, the UE does not need to feedback ACK or NACK information to the BS either. However, currently, the communication protocol supports three types of feedback codebooks, and the UE must feedback ACK or NACK information without discrimination for all enabled and disabled HARQ processes during the process of constructing the feedback codebook, resulting in unnecessary overhead and affecting the transmission efficiency of the feedback information. Summary of the Invention

[0027] The present application will be described below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be arbitrarily combined with each other. Additionally, it should be noted that, for the sake of description, only parts related to the present application rather than all structures are shown in the drawings.

[0028] In an embodiment of the present application, a feedback codebook generating method is provided, which is applied to a first communication node. The first communication node, as the data receiving end, can send a feedback codebook to a second communication node (i.e., the data sending end) to feedback ACK or NACK information for the received data, and request the second communication node to retransmit the data with transmission failure. This method is applicable to different types of feedback codebooks. The first communication node generates a feedback codebook for the enabled HARQ processes according to the configuration mode of the HARQ processes, and there is no need to transmit feedback information for the non-enabled HARQ processes, reducing the transmission overhead of the feedback codebook and improving the transmission efficiency.

[0029] Figure 1 Flowchart of a feedback codebook generating method provided for one embodiment, as Figure 1 shown, the method provided in this embodiment includes step 110 and step 120.

[0030] In step 110, determine the configuration mode of the hybrid automatic repeat request (HARQ) process, where the configuration mode of the HARQ process includes enabled and non-enabled.

[0031] In step 120, generate a feedback codebook according to the configuration mode of the HARQ process, where the feedback codebook contains feedback information corresponding to the enabled HARQ processes.

[0032] In this embodiment, the HARQ process is used to schedule the transmission of data on the Physical Downlink Shared Channel (PDSCH). The first communication node feeds back to the second communication node whether it has successfully detected the PDSCH scheduled by each enabled HARQ process. If so, it feeds back ACK information; otherwise, it feeds back NACK information. The configuration mode of each HARQ process can be configured by the second communication node and indicated to the first communication node. The HARQ process includes enabled HARQ processes and disabled HARQ processes. The feedback codebook contains the feedback information corresponding to each enabled HARQ process, but does not contain or only contains a small amount of feedback information of disabled HARQ processes. For example, in the case where a disabled HARQ process and an enabled HARQ process are in the same time slot (Slot), the feedback codebook contains the feedback information corresponding to the enabled HARQ process in this time slot, and may also contain the feedback information of the disabled HARQ process in this time slot.

[0033] In this embodiment, there are three types of feedback codebooks, including Type-1 codebook, Type-2 codebook, and Type-3 codebook. The second communication node can indicate to the first communication node which type of feedback codebook to use through Radio Resource Control (RRC), Medium Access Control (MAC), or Downlink Control Information (DCI).

[0034] In one embodiment, it further includes:

[0035] Step 1010: Receive time slot set information, where the time slot set information includes the time slots included in each time slot set and the configuration mode of the HARQ process corresponding to each time slot set.

[0036] In this embodiment, for the Type-1 codebook, the second communication node may divide a time slot into at least one time slot set. Each time slot set contains at least one time slot, and each time slot set corresponds to a configuration mode of a HARQ process. The second communication node sends the time slot set information to the first communication node to indicate the time slot set where the enabled HARQ process is located, and the first communication node feeds back ACK or NACK information for the time slot set where the enabled HARQ process is located. For example, the time slot is divided into time slot set 1 and time slot set 2. Among them, for time slot set 1, the second communication node schedules the PDSCH using the enabled HARQ process, that is, the configuration mode of the HARQ process corresponding to each time slot in time slot set 1 is enabled; for time slot set 2, the second communication node schedules the PDSCH using the non-enabled HARQ process, that is, the configuration mode of the HARQ process corresponding to each time slot in time slot set 2 is non-enabled.

[0037] In one embodiment, step 120 includes:

[0038] For each time slot in the time slot set where the configuration mode of the HARQ process is enabled, allocate feedback space for the PDSCH scheduled for the HARQ process in this time slot;

[0039] Insert the feedback information corresponding to each HARQ process in this time slot into the feedback space to obtain the feedback codebook.

[0040] For example, the configuration mode of the HARQ process corresponding to each time slot in time slot set 1 is enabled, and the configuration mode of the HARQ process corresponding to each time slot in time slot set 2 is non-enabled. In this case, the first communication node allocates feedback space for the PDSCH scheduled for each HARQ process in time slot set 1 and inserts ACK or NACK information according to the detection result of the PDSCH, while for the HARQ process in time slot set 2, there is no need to feedback ACK or NACK information. In the process of generating the feedback codebook, there is no need to allocate feedback space for the PDSCH scheduled for the HARQ process in time slot set 2.

[0041] In one embodiment, the feedback codebook further includes the cell (Cell), time slot (Slot), transport block (TB), and code block group (CBG) associated with the feedback information.

[0042] Figure 2Schematic diagram of a feedback codebook of the first type. In this embodiment, the feedback codebook is a Type-1 codebook, and the feedback codebook is constructed based on four dimensions: cell, time slot, transport block, and codebook block group. The size of the Type-1 codebook depends on the RRC layer configuration information. When the configuration is determined, the size of the codebook is fixed and will not cause inconsistent understandings of the size of the codebook and the association relationship between the PDSCH and the feedback information due to the missed detection of one or more PDSCHs. Therefore, the Type-1 codebook has good robustness.

[0043] As Figure 2 shown. Each bold long rectangle corresponds to the feedback space of a PDSCH occasion, and each long square corresponds to the information bit of a feedback message (ACK or NACK message). Figure 2 In, three Cells are configured for the first communication node. Among them, Cell-0 is configured with one TB, that is, TB0, Cell-1 is configured with at most two TBs, that is, TB0 and TB1, and Cell-2 is configured with at most two TBs, that is, TB0 and TB1, and a CBG feedback mode is configured. The maximum number of CBGs is 2, that is, including CBG-0 and CBG-1. According to the existing protocol, if the first communication node receives a PDSCH at a PDSCH occasion, an ACK or NACK message is inserted in the information bit corresponding to the PDSCH occasion according to the detection result of the PDSCH; if the first communication node does not receive a PDSCH at the PDSCH occasion, a NACK message is inserted in the information bit corresponding to the PDSCH occasion. That is, the information bit in the Type-1 codebook has no association with the configuration mode of the HARQ process used to schedule the PDSCH. Even if the HARQ process is configured as disabled, ACK or NACK messages still need to be fed back. Otherwise, the size of the codebook will change dynamically, resulting in the loss of robustness of the Type-1 codebook.

[0044] Figure 3 Schematic diagram of allocating feedback space for PDSCH scheduled by HARQ process in a time slot provided by an embodiment. As Figure 3As shown in the figure, this embodiment is based on a Type-1 codebook and excludes the feedback space of PDSCH in the time slot set where the configuration mode of the HARQ process is disabled. For example, the second communication node notifies the first communication node through RRC signaling that Slot n-8, Slot n-6, Slot n-3, and Slot n-2 belong to time slot set 2, and Slot n-7, Slot n-5, Slot n-4, and Slot n-1 belong to time slot set 1 (shown as the dotted area). The configuration mode of the HARQ process corresponding to each time slot in time slot set 1 is enabled, and the configuration mode of the HARQ process corresponding to each time slot in time slot set 2 is disabled. In this case, the first communication node only needs to allocate feedback space for the PDSCH scheduled by the HARQ process in each time slot in time slot set 1, and insert ACK or NACK information according to the detection result of the PDSCH to generate the feedback codebook. The feedback codebook does not contain the feedback information corresponding to the HARQ process in time slot set 2.

[0045] In one embodiment, step 120 includes:

[0046] For a time slot where there is at least one enabled HARQ process and the PDSCH scheduled by at least one enabled HARQ process is successfully detected, allocate feedback space for the PDSCH scheduled by the HARQ process in this time slot;

[0047] Insert the feedback information corresponding to each HARQ process in this time slot into the feedback space to obtain the feedback codebook;

[0048] Wherein, the feedback information corresponding to the disabled HARQ process in this time slot is NACK information.

[0049] In this embodiment, for a Type-1 codebook, if at least one enabled HARQ process is used to schedule PDSCH in a time slot and the PDSCH scheduled by at least one enabled HARQ process is successfully detected, the first communication node allocates feedback space for the PDSCH scheduled by each HARQ process in this time slot and inserts ACK or NACK information. Among them, for the enabled HARQ process in this time slot, ACK or NACK information is inserted according to the detection result of the PDSCH, and for the disabled HARQ process in this time slot, NACK information is directly inserted. In this case, the feedback codebook contains not only the feedback information corresponding to the enabled HARQ process in this time slot, but also the feedback information of the disabled HARQ process in this time slot.

[0050] In one embodiment, for a time slot in which the configuration modes of all HARQ processes are disabled, or for a time slot in which there is at least one enabled HARQ process and the PDSCHs scheduled by each enabled HARQ process are all detected as failed, the feedback codebook does not include the feedback information corresponding to the HARQ processes in the time slot.

[0051] In this embodiment, for a time slot in which the configuration modes of all HARQ processes are disabled, or for a time slot in which there are enabled HARQ processes but the PDSCHs scheduled by all the enabled HARQ processes are all detected as failed, no feedback space is allocated for the PDSCHs scheduled by the HARQ processes in the time slot, that is, no ACK or NACK information is fed back, thereby reducing the transmission overhead of the feedback codebook.

[0052] Figure 4 FIG. is a schematic diagram of allocating feedback space for a successfully detected PDSCH scheduled by an enabled HARQ process provided in an embodiment. Based on the Type-1 codebook, this embodiment eliminates the feedback space of the PDSCHs in the time slots in which the configuration modes of all HARQ processes are disabled, and also eliminates the feedback space of the PDSCHs in the time slots in which the PDSCHs scheduled by the enabled HARQ processes are all detected as failed. As Figure 4 shown, the configuration modes of the HARQ processes corresponding to the PDSCH opportunities indicated by the dotted areas are enabled, and the configuration modes of the HARQ processes corresponding to the PDSCH opportunities indicated by the white areas are disabled. Among them, the HARQ processes scheduling the PDSCHs in Slot n-8 and Slot n-3 are both enabled, and feedback space is allocated for the PDSCHs scheduled by the HARQ processes in Slot n-8 and Slot n-3; the HARQ processes scheduling the PDSCHs in Slot n-7, Slot n-4, Slot n-2, and Slot n-1 are all disabled, and no feedback space is allocated for the PDSCHs scheduled by the HARQ processes in these time slots. In addition, in Slot n-6 and Slot n-5, there are PDSCHs scheduled by both enabled and disabled HARQ processes. The PDSCHs scheduled by the enabled HARQ processes in Slot n-5 are all detected as incorrect. In this case, no feedback space is allocated for the PDSCHs scheduled by the HARQ processes in Slot n-5; in Slot n-6, the PDSCHs scheduled by the enabled HARQ processes are detected as successful, then the feedback space corresponding to the time slot is all reserved. In this case, for the PDSCHs scheduled by the enabled HARQ processes in Slot n-6, ACK or NACK information is inserted in the corresponding feedback space according to the detection results, and for the PDSCHs scheduled by the disabled HARQ processes, NACK information is inserted in the corresponding feedback space.

[0053] In one embodiment, step 120 includes:

[0054] For each PDSCH allocation feedback space scheduled for an enabled HARQ process, no feedback space is allocated for the PDSCH scheduled for a non-enabled HARQ process; feedback information corresponding to each enabled HARQ process is inserted into the feedback space to obtain the feedback codebook.

[0055] In this embodiment, for the Type-1 codebook, a feedback space is allocated for each PDSCH scheduled for an enabled HARQ process, and ACK or NACK information is inserted according to the detection result of the PDSCH. No feedback space is allocated for the PDSCH scheduled for a non-enabled HARQ process.

[0056] Figure 5 It is a schematic diagram for allocating a feedback space for a PDSCH scheduled for an enabled HARQ process provided in an embodiment. Based on the Type-1 codebook, this embodiment eliminates the feedback space for the PDSCH scheduled for a non-enabled HARQ process. As Figure 5 shown, the configuration mode of the HARQ process corresponding to the PDSCH opportunity shown in the dotted area is enabled, and the configuration mode of the HARQ process corresponding to the PDSCH opportunity shown in the white area is non-enabled. Among them, the HARQ processes scheduling the PDSCH in Slot n-8 and Slot n-3 are both enabled, and feedback spaces are allocated for the PDSCHs scheduled for the HARQ processes in Slot n-8 and Slot n-3; the HARQ processes scheduling the PDSCH in Slot n-7, Slot n-4, Slot n-2, and Slot n-1 are all non-enabled, and no feedback spaces are allocated for the PDSCHs scheduled for the HARQ processes in these time slots. In addition, in Slot n-6 and Slot n-5, there are PDSCHs scheduled for both enabled and non-enabled HARQ processes, and only the feedback space for the PDSCH scheduled for the enabled HARQ process needs to be allocated.

[0057] In one embodiment, it further includes:

[0058] Step 1020: Receive DCI, where the DCI includes a first parameter, a second parameter, and a third parameter for each HARQ process; the feedback codebook also includes the first parameter, the second parameter, and the third parameter associated with the feedback information; wherein, the first parameter is used to indicate the number of transmissions of the PDSCH during the period from receiving the DCI to scheduling the PDSCH by the target HARQ process, the second parameter is used to indicate the total number of transmissions of the PDSCH during the period from receiving the DCI to the end of the time slot when the PDSCH is scheduled by the target HARQ process, and the third parameter is used to indicate the number of transmissions of the PDSCH scheduled by the enabled HARQ process during the period from receiving the DCI to the end of the time slot when the PDSCH is scheduled by the target HARQ process.

[0059] In this embodiment, for the Type-2 codebook, feedback space is allocated for the PDSCH scheduled by each enabled HARQ process and ACK or NACK information is inserted, and no feedback space is allocated for the PDSCH not scheduled by the enabled HARQ process, and the feedback codebook is also related to the first parameter, the second parameter, and the third parameter of each HARQ process.

[0060] Figure 6 It is a schematic diagram of the second type of feedback codebook. As Figure 6 shown, the PDSCH indicated by the dotted area is scheduled by the HARQ process, and the PDSCH indicated by the grid area is not scheduled by the HARQ process. In the standard protocol, the Type-2 codebook is generated according to the indication of the binary parameters (cDAI, tDAI) in the DCI, where cDAI indicates the number of transmissions of the PDSCH during the period from receiving the DCI to scheduling the PDSCH by the current target HARQ process, and tDAI indicates the total number of transmissions of the PDSCH on all carriers during the period from receiving the DCI to the time slot where the PDSCH scheduled by the current target HARQ process is located, that is, the highest cDAI value on all current carriers. For example, for the PDSCH shown by the 4th dotted rectangle in Cell-2, the corresponding binary number is (7, 8). Taking the HARQ process scheduling this PDSCH as the target HARQ process, the number of transmissions of the PDSCH during the period from receiving the DCI to scheduling the PDSCH by the target HARQ process is 7, and the total number of transmissions of the PDSCH on all carriers during the period from receiving the DCI to the end of the time slot when the PDSCH is scheduled by the target HARQ process is 8. The first communication node can determine whether there is a missed detection of the PDSCH by detecting (cDAI, tDAI). Whether there is a missed detection or not, the size of the Type-2 codebook will not change and is independent of the configuration mode of the HARQ process.

[0061] Figure 7 It is a schematic diagram for allocating feedback space for the PDSCH scheduled by the enabled HARQ process provided in an embodiment. As Figure 7As shown, in this embodiment, the PDSCH shown in the white area is scheduled by a non-enabled HARQ process, the PDSCH shown in the dotted area is scheduled by an enabled HARQ process, and the PDSCH shown in the grid area is not scheduled by an HARQ process. Based on the Type-2 codebook, the DCI includes a first parameter (i.e., cDAI), a second parameter (i.e., tDAI), and a third parameter (denoted as tDAI2) for each HARQ process, where the third parameter indicates the number of transmissions of the PDSCH scheduled by the enabled HARQ process on all carriers between the time when the DCI is received and the time slot in which the PDSCH scheduled by the current target HARQ process is located. For example, for the PDSCH shown in the fourth dotted rectangle of Cell-2, the corresponding binary number is (7, 8). Taking the HARQ process that schedules this PDSCH as the target HARQ process, the number of transmissions of the PDSCH during the period from receiving the DCI to the scheduling of the PDSCH by the target HARQ process is 7, the total number of transmissions of the PDSCH on all carriers during the period from receiving the DCI to the end of the time slot in which the PDSCH is scheduled by the target HARQ process is 8, and the number of transmissions of the PDSCH scheduled by the enabled HARQ process on all carriers during the period from receiving the DCI to the end of the time slot in which the PDSCH is scheduled by the target HARQ process is 4. When the first communication node receives the DCI information, according to the configuration mode of each HARQ process, it allocates feedback space for the PDSCH scheduled by the enabled HARQ process and inserts ACK or NACK information according to the detection result of the PDSCH; by detecting the ternary parameters (cDAI, tDAI, TDAI, 2), it can be determined whether there is a missed detection of the PDSCH and whether there is a missed detection of the PDSCH scheduled by the enabled HARQ process, and then the size of the feedback codebook and the position of the PDSCH scheduled by the enabled HARQ process corresponding to the feedback space can be determined.

[0062] In one embodiment, it further includes:

[0063] Step 1030: Receive process grouping information, where the process grouping information includes the enabled HARQ processes included in each group;

[0064] Step 1040: Receive DCI, where the DCI is used to indicate the group for which feedback information needs to be reported.

[0065] In this embodiment, for the Type-3 codebook, the second communication node groups the enabled HARQ processes and sends the process grouping information to the first communication node. On this basis, the first communication node determines the group for which feedback information needs to be reported according to the indication of the DCI, allocates feedback space for each PDSCH scheduled by the enabled HARQ process in the group and inserts ACK or NACK information, and does not allocate feedback space for the group for which feedback information does not need to be reported.

[0066] In one embodiment, step 120 includes:

[0067] Allocating a feedback space for each HARQ process in a packet that needs to report feedback information;

[0068] Inserting the feedback information corresponding to each HARQ process into the feedback space to obtain the feedback codebook.

[0069] In this embodiment, for the Type-3 codebook, a feedback space is allocated for each enabled HARQ process in a packet indicated by DCI that needs to report feedback information, and ACK or NACK information is inserted. For the PDSCH scheduled by the HARQ process in a packet not indicated by DCI, no feedback space is allocated.

[0070] For example, the enabled HARQ processes are divided into K groups, where K≥1. When K>1, the second communication node notifies the first communication node of the process grouping information through RRC signaling. The process grouping information includes the number of groups, the HARQ processes corresponding to each group, etc., and indicates the packet for which the first communication node needs to report the feedback codebook through DCI signaling. The first communication node allocates a feedback space for the enabled HARQ processes in the packet indicated by the DCI signaling and generates a feedback codebook.

[0071] In one embodiment, the feedback codebook further includes the cell, HARQ process, transport block, and codebook block group associated with the feedback information.

[0072] Figure 8 Schematic diagram of a third type of feedback codebook provided for an embodiment. In this embodiment, the feedback codebook is a Type-3 codebook, and the feedback codebook is constructed based on four dimensions: cell, HARQ process, transport block, and codebook block group. As Figure 8 shown. Each bold long rectangle corresponds to the feedback space of a PDSCH occasion, and each long square corresponds to an information bit of the feedback information. Figure 8In this case, three Cells are configured for the first communication node. Among them, Cell-0 is configured with one TB, namely TB0, Cell-1 is configured with at most two TBs, namely TB0 and TB1, and Cell-2 is configured with at most two TBs, namely TB0 and TB1. And a CBG feedback mode is configured, and the maximum number of CBGs is 2, namely including CBG-0 and CBG-1. According to the existing protocol, the second communication node triggers the first communication node to report the feedback codebook through DCI signaling. For each HARQ process corresponding to each cell, if the second communication node uses this HARQ process to schedule the PDSCH, the first communication node inserts ACK or NACK information in the corresponding feedback space according to the result of PDSCH detection; if the second communication node does not use this HARQ process to schedule the PDSCH, NACK needs to be inserted in the corresponding feedback space.

[0073] Figure 9 A schematic diagram for allocating feedback space for each HARQ process in a packet that needs to report feedback information provided for an embodiment. In this embodiment, based on the Type-3 codebook, feedback space is only allocated for the PDSCH scheduled by the enabled HARQ processes in the packet indicated in the DCI, and the feedback space corresponding to the PDSCH scheduled by the HARQ processes in the packet not indicated in the DCI is excluded, thereby reducing the overhead of the feedback codebook. As Figure 9 shown, the second communication node configures 8 enabled HARQ processes (denoted as HARQ#0 to HARQ#8) for the first communication node in Cell-0. Among them, HARQ#0 / 1 / 2 / 3 are divided into packet 1, and HARQ#4 / 5 / 6 / 7 are divided into packet 2. The second communication node informs the first communication node of the process grouping information through RRC signaling. The second communication node triggers the first communication node to report the feedback codebooks of packet 1 and packet 2 through DCI in slot4 and slot8 respectively, then the first communication node only allocates feedback space for the HARQ processes in the packet indicated by the DCI when constructing the codebook. In addition, the second communication node can cyclically trigger the reporting of the feedback codebooks of packet 1 and packet 2 through DCI signaling, and a ping-pong operation is formed between the HARQ processes in the two packets, and the second communication node BS can continuously transmit PDSCH to the first communication node.

[0074] Figure 10 Another schematic diagram for allocating feedback space for each HARQ process in a packet that needs to report feedback information provided for an embodiment. As Figure 10As shown, the second communication node configures 8 HARQ processes (denoted as HARQ#0 to HARQ#8) for the first communication node in Cell-0. Among them, HARQ#0 / 1 / 2 / 3 are enabled HARQ processes, and HARQ#4 / 5 / 6 / 7 are disabled HARQ processes. For HARQ#0 / 1 / 2 / 3, HARQ#0 / 1 are grouped into one group, denoted as Group 1, and HARQ#2 / 3 are grouped into one group, denoted as Group 2. The second communication node notifies the first communication node of the process grouping information through RRC signaling. The second communication node triggers the first communication node to report the feedback codebook of Group 1 through DCI in slot2 and slot7, and triggers the first communication node to report the feedback codebook of Group 2 through DCI in slot4. The first communication node allocates feedback space for the enabled HARQ processes in the group according to the group indicated by DCI, and inserts ACK or NACK information in the corresponding feedback space according to the detection result of the PDSCH. For example, the first communication node is triggered to report the codebook of Group 1 in slot7, and in Slot4 / 5 / 6, the first communication node only detects the PDSCH scheduled by HARQ#0. When constructing the codebook, ACK information is inserted in the feedback space for the PDSCH scheduled by HARQ#0, and ACK information is inserted in the feedback space for the PDSCH scheduled by HARQ#1. No feedback space is allocated for the PDSCH scheduled by the disabled HARQ processes, and they do not participate in the construction of the codebook.

[0075] The embodiment of the present application further provides a method for receiving a feedback codebook, which is applied to the second communication node. As the data sender, the second communication node can receive the feedback codebook reported by the first communication node, and retransmit the data with transmission failure accordingly. This method is applicable to different types of feedback codebooks. The second communication node configures the configuration mode of the HARQ process, receives the feedback codebook for the enabled HARQ processes, and does not need to receive feedback information for the disabled HARQ processes, reducing the transmission overhead of the feedback codebook and improving the transmission efficiency. It should be noted that the operations performed by the second communication node correspond to those performed by the first communication node. For technical details not described in detail in this embodiment, reference can be made to any of the above embodiments.

[0076] Figure 11 As shown in the flowchart of a method for receiving a feedback codebook provided in an embodiment, Figure 11 As shown, the method provided in this embodiment includes step 210 and step 220.

[0077] In step 210, configure the configuration mode of the HARQ process, and the configuration mode of the HARQ process includes enabled and disabled.

[0078] In step 220, a feedback codebook is received according to the configuration mode of the HARQ process, and the feedback information corresponding to the enabled HARQ process is included in the feedback codebook.

[0079] In one embodiment, it further includes:
