Description

[0001] This disclosure is a divisional application of application number 202180002803.9, and the invention title is: A codebook feedback method, a codebook feedback device, and a storage medium Technical Field

[0002] The present disclosure relates to the field of communication technology, and in particular to a codebook feedback method, a codebook feedback device, and a storage medium. Background Art

[0003] In the related art, a mechanism for disabling some Hybrid Automatic Repeat reQuest (HARQ) feedback is introduced to improve system efficiency. For example, a mechanism for disabling some HARQ process feedback is introduced in the feedback mechanism for non-terrestrial networks (NTN) to improve system efficiency.

[0004] Based on the HARQ feedback disabling mechanism, different terminal manufacturers currently have different opinions on HARQ codebook feedback. Some manufacturers advocate not enhancing the HARQ codebook, so that the network equipment can use the HARQ results of the HARQ process disabled by the terminal to understand the decoding situation, so as to use more appropriate transmission parameters, and not enhancing the HARQ codebook can also simplify the complexity of the UE. Some manufacturers advocate enhancing the HARQ codebook to reduce the size of the HARQ codebook, thereby reducing the interference caused by redundant information and unnecessary uplink transmission.

[0052] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0053] The codebook feedback method provided in the embodiments of the present disclosure is applied to an NTN network, for example, to a satellite communication system, or a high altitude platform station (HAPS) communication system. The embodiments of the present disclosure are described by taking a satellite communication system as an example. Figure 1 FIG. 1 is a diagram showing an architecture of a satellite communication system according to an exemplary embodiment. Figure 1As shown, the satellite transmits beams through antennas to form satellite cells covered by the satellite network. The satellite is in a mobile state. The satellite cell can also be called a beam foot print. The coverage areas between satellite cells can be non-overlapping, partially overlapping, or completely overlapping. Satellite terminals can be deployed within the coverage of the satellite network. Satellite terminals within the coverage of the satellite network communicate via a service link between the satellite cell and the satellite. The satellite communicates with ground infrastructure, such as a gateway, via a feeder link, thereby achieving interactive communication with ground communication networks, such as a core network and a data network.

[0054] The terminals involved in the embodiments of the present disclosure may include, but are not limited to: cellular and / or satellite wireless telephones with or without multi-line displays; personal communication system (PCS) terminals that can combine wireless telephones with data processing, fax and / or data communication capabilities; personal digital assistants (PDAs) including radio frequency transceivers and pagers, Internet / intranet access, web browsers, organizers, calendars and / or global positioning system (GPS) receivers; and / or other devices including radio frequency transceivers. Among them, the terminals involved in the embodiments of the present disclosure are sometimes referred to as satellite terminals, wireless telephones, or terminals, and may also be referred to as terminal equipment, user equipment (UE), mobile stations (MS), mobile terminals (MT), etc.

[0055] The network devices involved in the embodiments of the present disclosure may include but are not limited to wireless base stations, satellite base stations, wireless transceiver equipment or ground base stations installed on aircraft that stay at high altitudes for a long time. The network devices involved in the embodiments of the present disclosure may also be understood as one or more infrastructure units deployed in a satellite communication system. Figure 2 and Figure 3 The following are respectively diagrams showing the architecture of a satellite communication system with base stations deployed therein involved in an exemplary embodiment of the present disclosure. Figure 2 In 5G networks, base stations (such as gNBs in 5G networks) are independent of satellites and gateways in remote radio units. Satellite terminals access base stations through air interfaces (uu), such as new radio (NR) uu, and connect to the core network and data network through NG interfaces for communication. Among them, base stations, satellites, and gateways can be understood as NG radio access networks (Radio Access Network, RAN). Figure 3In 5G networks, base stations (such as gNBs in 5G networks) can be deployed together with satellites and form NG RAN with gateways. Satellite terminals are connected to base stations through air interfaces and to core networks and data networks through NG interfaces for communication.

[0056] In the NTN network, the HARQ efficiency is reduced due to the excessive round-trip time (RTT), so a feedback mechanism for closing some HARQ processes is introduced in the feedback mechanism of the NTN network to improve the system feedback efficiency. In the feedback mechanism for closing some HARQ processes, the relevant terminal manufacturers have different opinions on whether to enhance the HARQ codebook for feedback. Among them, the HARQ codebook includes Type-1HARQ codebook, Type-2HARQ and Type-3HARQ codebook. Among them, the Type-1HARQ codebook is also called a semi-static HARQ codebook, the Type-2HARQ codebook is also called a dynamic codebook, and the Type-3 HARQ codebook is also called a one-shot HARQ codebook. The following is an explanation using the Type-3 HARQ codebook as an example. Among them, in the following embodiments of the present disclosure, the Type-3 HARQ codebook and the One-shot HARQ codebook are sometimes used interchangeably, and those skilled in the art should understand the consistency of their meanings.

[0057] Regarding the One-shot HARQ codebook, some terminal manufacturers advocate not supporting the One-shot HARQ codebook in the NTN network. Some terminal manufacturers advocate not enhancing the One-shot HARQ codebook, believing that the HARQ results of the disabled HARQ process fed back by the terminal will help the network equipment understand the decoding situation and use more appropriate transmission parameters. In addition, not enhancing the codebook can also simplify the complexity of the terminal. Some terminal manufacturers advocate enhancing the One-shot HARQ codebook, with the main motivation being to reduce the size of the One-shot HARQ codebook, thereby reducing processing overhead and interference caused by unnecessary uplink transmission. Among them, for the enhancement of the One-shot HARQ codebook, the consistency of the enhancement scheme is relatively convergent, mainly including: the One-shot HARQ codebook contains the HARQ process configured enabled by the Radio Resource Control (RRC), and the One-shot HARQ codebook can be transmitted on the Physical Uplink Control Channel (PUCCH) / Physical Uplink Shared Channel (PUSCH).

[0058] In the related art, the transmission of the One-shot HARQ codebook on the PUSCH is triggered and activated by downlink control information (DCI). Therefore, when the One-shot HARQ codebook is transmitted on the PUSCH, there is no corresponding DAI value in the DCI to indicate whether the One-shot HARQ codebook is multiplexed on the PUSCH for transmission.

[0059] However, in the NTN network, different manufacturers hold different opinions on whether the One-shot HARQ codebook should be enhanced. Through the DCI used for downlink scheduling, such as DCI format 1-1, which triggers the feedback method of the One-shot HARQ codebook, it is possible that the UE needs to perform One-shot HARQ codebook feedback on the PUSCH, but the DCI used for uplink scheduling, such as DCI format 1-0, does not contain the DAI field related to the one-shot codebook (i.e., the information field used to indicate whether the PUSCH contains the one-shot codebook). Therefore, the feedback method of the One-shot HARQ codebook needs to be further improved.

[0060] The embodiment of the present disclosure provides a codebook feedback method, in which a network device configures One-shot HARQ codebook configuration information for a terminal and sends DAI indication information, so as to introduce DAI indication information into the One-shot HARQ codebook feedback technology.

[0061] Figure 4 is a flow chart of a codebook feedback method according to an exemplary embodiment. Figure 4 As shown, the codebook feedback method is used in a network device and includes the following steps.

[0062] In step S11, One-shot HARQ codebook configuration information is configured.

[0063] In step S12, DAI indication information is sent.

[0064] In the disclosed embodiment, the network device configures One-shot HARQ codebook configuration information for the terminal, and the terminal can perform One-shot HARQ codebook feedback.

[0065] In one implementation, the network device configures One-shot HARQ codebook configuration information for the terminal, and sends trigger indication information for triggering the terminal to perform One-shot HARQ codebook feedback, so as to trigger the terminal to perform One-shot HARQ codebook feedback.

[0066] The trigger indication information may include DCI, for example, triggering the terminal to perform One-shot HARQ codebook feedback through DCI. The network device may trigger the terminal to perform One-shot HARQ codebook feedback through DCI 0-1 / DCI0-2.

[0067] In one implementation, the disclosed embodiment may introduce a new information field in DCI for sending DAI indication information. For example, a new field, such as 3rd DAI, is introduced in DCI 0-1 / 0-2 to send DAI indication information.

[0068] In the codebook feedback method provided by the embodiment of the present disclosure, the DAI indication information sent by the network device to the terminal is used to indicate whether the terminal reuses PUSCH resources and feeds back the One-shot HARQ codebook.

[0069] In one implementation, the DAI indication information includes an information field for indicating whether the terminal multiplexes PUSCH resources and feeds back a One-shot HARQ codebook, hereinafter referred to as a first information field.

[0070] In one example, the first information field may be a new field introduced in DCI 0-1 / 0-2, such as 3rd DAI.

[0071] Among them, the bit position of the first information field can be 0 bit or 1 bit. Among them, when the terminal is not configured with a one-shot HARQ codebook by the network device, the first information field is 0 bit, and there is no need to send DAI indication information about the one-shot HARQ codebook to the terminal. When the terminal is configured with a one-shot HARQ codebook by the network device and the first information field is 1 bit, the bit position is used to indicate whether the terminal needs to feedback the One-shot HARQ codebook in the PUSCH. Among them, when the first information field is 1 bit, different bit values ​​indicate whether the terminal reuses the resources of PUSCH and feeds back the One-shot HARQ codebook. For example, when the bit value of the first information field is 1, it indicates that the terminal reuses the resources of PUSCH to feed back the One-shot HARQ codebook. When the bit value of the first information field is 0, it indicates that the terminal does not reuse the resources of PUSCH to feed back the One-shot HARQ codebook. Alternatively, when the first information field bit value is 0, it indicates that the terminal multiplexes the PUSCH resource feedback One-shot HARQ codebook, and when the first information field bit value is 1, it indicates that the terminal does not multiplex the PUSCH resource feedback One-shot HARQ codebook.

[0072] The One-shot HARQ codebook fed back by the terminal may sometimes include or not include New Data Indicator (NDI) information.

[0073] In the codebook feedback method provided by the embodiment of the present disclosure, the DAI indication information sent by the network device to the terminal is used to indicate whether the terminal reuses the PUSCH resource feedback One-shot HARQ codebook, and whether the One-shot HARQ codebook contains NDI information.

[0074] In the embodiment of the present disclosure, the information field used to indicate whether the terminal multiplexes the resource feedback One-shot HARQ codebook of PUSCH and whether the One-shot HARQ codebook contains NDI information is referred to as the second information field. The DAI indication information includes the second information field, and the second information field is used to indicate whether the terminal multiplexes the resource feedback One-shot HARQ codebook of PUSCH and whether the One-shot HARQ codebook contains NDI information.

[0075] In one example, the second information field may be a new field introduced in DCI 0-1 / 0-2, such as 3rd DAI.

[0076] Among them, the bit position of the second information field can be 0 bit or 2 bits. Among them, when the terminal is not configured with a one-shot HARQ codebook by the network device, the second information field is 0 bit, and there is no need to send DAI indication information about the one-shot HARQ codebook to the terminal. When the terminal is configured with a one-shot HARQ codebook by the network device and the second information field is 2 bits, the bit position is used to indicate whether the terminal needs to feedback the One-shot HARQ codebook in the PUSCH. Among them, when the second information field is 2 bits, different bit values ​​indicate whether the terminal reuses the resource feedback One-shot HARQ codebook of PUSCH, and / or whether the One-shot HARQ codebook contains NDI information. For example, when the value of the second information field bit is 10, it indicates that the One-shot HARQ codebook does not contain NDI information. When the value of the second information field bit is 01, it indicates that the One-shot HARQ codebook contains NDI information. When the value of the second information field bit is 00, it indicates that the resource feedback One-shot HARQ codebook of PUSCH is not multiplexed. When the value of the bit in the second information field is not 0, it indicates that the resource multiplexing PUSCH feeds back the One-shot HARQ codebook.

[0077] In the embodiment of the present disclosure, the One-shot HARQ codebook configuration information configured by the network device may include configuration information for an enhanced One-shot HARQ codebook, or may also include codebook configuration information for a non-enhanced One-shot HARQ codebook.

[0078] Among them, for the convenience of description in the disclosed embodiment, the configuration information of the enhanced One-shot HARQ codebook is referred to as the first HARQ codebook configuration information. Among them, the first HARQ codebook configuration information is used to configure the terminal to configure the codebook using the first codebook configuration method. The codebook configuration information of the One-shot HARQ codebook that is not enhanced is referred to as the second HARQ codebook configuration information. Among them, the configuration information of the second HARQ codebook is used to configure the terminal to configure the codebook using the first codebook configuration method. Among them, the first codebook configuration method can be understood as a HARQ codebook configuration method corresponding to the enhanced HARQ codebook configuration capability. The second codebook configuration method can be understood as a HARQ codebook configuration method that matches the HARQ codebook configuration capability that is not enhanced. Among them, the first codebook configuration method can also be understood as an enhancement of the second codebook configuration method.

[0079] The codebook configuration methods included in the first codebook configuration method in the embodiment of the present disclosure may include one or more, for example, may include one or more enhancement schemes for One-shot HARQ codebooks in related technologies. The codebook configuration methods included in the second codebook configuration method may also include one or more.

[0080] The network device may configure the first HARQ codebook configuration information or the second HARQ codebook configuration information for the terminal based on whether the terminal supports the enhanced One-shot HARQ codebook capability.

[0081] Figure 5 1 is a flowchart of a codebook feedback method according to an exemplary embodiment. The codebook feedback method can be performed alone or in combination with other embodiments of the present disclosure. Figure 5 As shown, the codebook feedback method is used in a network device and includes the following steps.

[0082] In step S21, capability information sent by the terminal is received, where the capability information sent by the terminal is used to indicate a HARQ codebook configuration mode supported by the terminal under a partial HARQ disabling mechanism.

[0083] In the disclosed embodiment, the terminal may send capability information indicating the HARQ codebook configuration capability supported by the terminal to the network device based on whether the supported codebook configuration mode is the first codebook configuration mode or the second codebook configuration mode. The network device obtains the capability information sent by the terminal.

[0084] In the embodiment of the present disclosure, the network device obtains the capability information of the terminal. On the one hand, the terminal can send the capability information to the network device separately.

[0085] In one implementation, when the terminal separately sends capability information for indicating the HARQ codebook configuration capability supported by the terminal to the network device, information dedicated to indicating the HARQ codebook configuration capability of the terminal for the HARQ codebook can be designed. Hereinafter, the information dedicated to indicating the HARQ codebook configuration capability of the terminal for the HARQ codebook is referred to as the first capability information. The network device obtains the first capability information, and the first capability information is information dedicated to indicating the HARQ codebook configuration capability of the terminal for the One-shot HARQ codebook.

[0086] In one example, it is assumed that the One-shot HARQ codebook supported by the terminal is a One-shot HARQ codebook with enhanced configuration capability. The first capability information sent by the terminal to the network device may be information dedicated to indicating the HARQ codebook configuration capability of the terminal for the One-shot HARQ codebook.

[0087] In an example, in an NTN network, the information element (IE) including the first capability information reported by the terminal obtained by the network device may be as follows:

[0088]

[0089] On the other hand, the terminal may also send capability information indicating the HARQ codebook configuration capability supported by the terminal together with other information to the network device. Among them, other information can be understood as information other than the HARQ codebook configuration capability information that is different from the HARQ codebook. In one example, the other information can also be understood as other signaling that can carry the capability information of the HARQ codebook configuration capability supported by the terminal. Among them, the capability information used to indicate the HARQ codebook configuration capability supported by the terminal, and other information other than the HARQ codebook configuration capability information that is different from the HARQ codebook can be carried in the same information and sent to the terminal. For example, the capability information used to indicate the HARQ codebook configuration capability supported by the terminal may be carried in other signaling. The information that carries the capability information indicating the HARQ codebook configuration capability supported by the terminal, as well as other information, is referred to as the second capability information below.

[0090] In the disclosed embodiment, the network device obtains the second capability information sent by the terminal, and the indication of the capability information of the HARQ codebook configuration capability supported by the terminal may be an explicit indication or an implicit indication. For example, the second capability information includes a bit for indicating different HARQ codebook configuration capabilities, and different HARQ codebook configuration capabilities are explicitly indicated by different values ​​of the bit. Or for another example, when the second capability information does not include a bit indicating different HARQ codebook configuration capabilities, it can be understood as an implicit indication that the terminal supports the HARQ codebook configuration capability that is not enhanced.

[0091] In one example, it is assumed that the One-shot HARQ codebook configuration capability supported by the terminal is the enhanced One-shot HARQ codebook. The second capability information sent by the terminal and acquired by the network device includes the enhanced One-shot HARQ codebook and related information of other HARQ codebooks such as the Type-2 HARQ codebook and the Type-1 HARQ codebook.

[0092] In an example, in an NTN network, the information element including the second capability information reported by the terminal and obtained by the network device may be as follows:

[0093]

[0094]

[0095] In the embodiment of the present disclosure, on the one hand, the terminal may send capability information to the network device when it is determined that the supported codebook configuration mode is the first codebook configuration mode. The network device receives the capability information sent by the terminal indicating support for the first codebook configuration mode. On the other hand, when the terminal determines that the supported codebook configuration mode is the second codebook configuration mode, the terminal does not send capability information to the network device. When the network device determines that the capability information is not received, it determines that the terminal supports the second codebook configuration mode.

[0096] In the disclosed embodiment, the network device may configure the codebook configuration information of the One-shot HARQ codebook for the terminal based on the received capability information.

[0097] Figure 6 1 is a flowchart of a codebook feedback method according to an exemplary embodiment. The codebook feedback method can be performed alone or in combination with other embodiments of the present disclosure. Figure 6 As shown, the codebook feedback method is used in a network device and includes the following steps.

[0098] In step S31, codebook configuration information of a One-shot HARQ codebook is configured for the terminal based on the capability information of the terminal.

[0099] In the disclosed embodiment, the network device obtains capability information sent by the terminal, where the capability information is used to indicate the One-shot HARQ codebook configuration capability supported by the terminal, so that the network device can configure the One-shot HARQ codebook configuration information for the terminal based on the capability information.

[0100] The codebook configuration information of the One-shot HARQ codebook includes first HARQ codebook configuration information or second HARQ codebook configuration information.

[0101] In one implementation of the disclosed embodiment, the network device determines that the terminal supports the first codebook configuration mode based on the capability information of the terminal, and the One-shot HARQ codebook configuration information configured for the terminal is the first HARQ codebook configuration information or the second HARQ codebook configuration information.

[0102] In another implementation of the disclosed embodiment, the network device determines that the terminal supports the second codebook configuration mode based on the capability information of the terminal, and the One-shot HARQ codebook configuration information configured for the terminal is the second HARQ codebook configuration information.

[0103] In the codebook feedback method provided by the embodiment of the present disclosure, based on the HARQ codebook configuration capability supported by the terminal, the network device can configure the first HARQ codebook configuration information or the second HARQ codebook configuration information for the terminal, and the terminal configures the codebook using the codebook configuration method corresponding to the configured codebook configuration information.

[0104] In the disclosed embodiment, the network device configures the codebook configuration information of the One-shot HARQ codebook for the terminal, and can use the first HARQ codebook configuration information or the second HARQ codebook configuration information through RRC information configuration.

[0105] In one example, whether to use the One-shot HARQ enhanced codebook is configured through RRC. The enhanced codebook of the One-shot HARQ codebook is called, for example, enhanced type-3 HARQ codebook. If the terminal supports the One-shot HARQ enhanced codebook, the terminal is configured to generate the codebook and feedback in an enhanced codebook manner, such as only providing feedback for an enabled HARQ process. If the terminal does not support the One-shot HARQ enhanced codebook, feedback is provided in accordance with the One-shot HARQ codebook of the related technology.

[0106] In one example, an example of configuring a One-shot HARQ enhanced codebook through RRC information is as follows:

[0107]

[0108] In the codebook feedback method provided in the embodiment of the present disclosure, a configuration mode for enhancing or not enhancing the One-shot HARQ codebook is implemented.

[0109] Among them, the network device triggers One-shot HARQ enhanced codebook feedback or One-shot HARQ non-enhanced codebook feedback for the terminal, and can further send DAI indication information to indicate whether the One-shot HARQ enhanced codebook or One-shot HARQ non-enhanced codebook reuses PUSCH resources for feedback. In addition, it can further indicate whether the One-shot HARQ enhanced codebook or One-shot HARQ non-enhanced codebook includes NDI information.

[0110] Based on the same concept, an embodiment of the present disclosure also provides a codebook feedback method applied to a terminal.

[0111] Figure 7 1 is a flowchart of a codebook feedback method according to an exemplary embodiment. The codebook feedback method can be performed alone or in combination with other embodiments of the present disclosure. Figure 7 As shown, the codebook feedback method is used in a network device and includes the following steps.

[0112] In step S41, One-shot HARQ codebook configuration information is received, and DAI indication information is received.

[0113] In step S42, based on the DAI indication information, the One-shot HARQ codebook is fed back.

[0114] In the disclosed embodiment, the terminal may receive One-shot HARQ codebook configuration information through RRC information.

[0115] In one implementation, the disclosed embodiment may introduce a new information field in DCI for receiving DAI indication information. For example, a new field, such as 3rd DAI, is introduced in DCI 0-1 / 0-2 to receive DAI indication information.

[0116] In one implementation, the DAI indication information includes a first information field. The first information field is used to indicate whether the terminal reuses the resource feedback One-shot HARQ codebook of PUSCH. In one example, the first information field may be a new field introduced in DCI 0-1 / 0-2, such as 3rd DAI.

[0117] Among them, the bit position of the first information field can be 0 bit or 1 bit. Among them, when the first information field is 0 bit, there is no need to send DAI indication information to the terminal, and it can also be understood as an implicit indication that the terminal does not need to feedback the One-shot HARQ codebook. When the first information field is 1 bit, it indicates that the terminal needs to feedback the One-shot HARQ codebook. Among them, when the first information field is 1 bit, different bit values ​​indicate whether the terminal reuses PUSCH resources and feeds back the One-shot HARQ codebook.

[0118] In another implementation manner, the DAI indication information includes a second information field, and the second information field is used to indicate whether the terminal multiplexes the resource feedback One-shot HARQ codebook of the PUSCH, and whether the One-shot HARQ codebook includes NDI information.

[0119] In one example, the second information field may be a new field introduced in DCI 0-1 / 0-2, such as 3rd DAI.

[0120] Among them, the bit position of the second information field can be 0 bits or 2 bits. Among them, when the second information field is 0 bits, there is no need to send DAI indication information to the terminal, and it can also be understood as an implicit indication that the terminal does not need to feedback the One-shot HARQ codebook. When the second information field is 2 bits, it indicates that the terminal needs to feedback the One-shot HARQ codebook. Among them, when the second information field is 2 bits, different bit values ​​indicate whether the terminal reuses the PUSCH resource feedback One-shot HARQ codebook, and / or whether the One-shot HARQ codebook contains NDI information.

[0121] In one implementation, the One-shot HARQ codebook configuration information includes first HARQ codebook configuration information or second HARQ codebook configuration information. The first HARQ codebook configuration information is used to configure the terminal to configure the codebook in a first codebook configuration manner, and the second HARQ codebook configuration information is used to configure the terminal to configure the codebook in a second codebook configuration manner. The first codebook configuration manner is an enhancement of the second codebook configuration manner.

The One-shot HARQ codebook configuration information includes second HARQ codebook configuration information, and the terminal configures the codebook to generate and feedback the One-shot HARQ codebook in the second codebook configuration mode.

[0123] Further, in the codebook feedback method provided in the embodiment of the present disclosure, the terminal receives trigger indication information used to trigger the terminal to perform One-shot HARQ feedback, and triggers feedback of the One-shot HARQ codebook based on the trigger indication information.

[0124] The trigger indication information may include DCI, for example, triggering the terminal to perform One-shot HARQ codebook feedback through DCI. The network device may trigger the terminal to perform One-shot HARQ codebook feedback through DCI 0-1 / DCI0-2. The terminal receives the trigger indication information through DCI 0-1 / DCI0-2.

[0125] In one implementation, the terminal may send capability information to the network device, where the capability information is used to indicate a HARQ codebook configuration mode supported by the terminal when a partial HARQ disabling mechanism is adopted.

[0126] Figure 81 is a flowchart of a codebook feedback method according to an exemplary embodiment. The codebook feedback method can be performed alone or in combination with other embodiments of the present disclosure. Figure 8 As shown, the codebook feedback method is used in a network device and includes the following steps.

The first capability information sent by the terminal to the network device can be information dedicated to indicating the HARQ codebook configuration capability of the terminal for the One-shot HARQ codebook.

[0130] In another implementation, the terminal sends a second capability information, and the second capability information includes HARQ codebook configuration capability information indicating the terminal for the HARQ codebook, and other information other than the HARQ codebook configuration capability information different from the HARQ codebook. In one example, it is assumed that the One-shot HARQ codebook configuration capability supported by the terminal is an enhanced One-shot HARQ codebook. The second capability information sent by the terminal obtained by the network device includes an enhanced One-shot HARQ codebook, and includes relevant information of other HARQ codebooks such as Type-2 HARQ codebooks and Type-1 HARQ codebooks.

[0131] In the codebook feedback method provided by the embodiment of the present disclosure, the terminal is triggered to perform One-shot HARQ codebook feedback, and receives DAI indication information to determine whether to multiplex PUSCH resources for feedback for One-shot HARQ enhanced codebook or One-shot HARQ non-enhanced codebook. Further, the terminal sends capability information so that the network device configures enhanced or non-enhanced codebook configuration information for the One-shot HARQ codebook based on the capability information of the terminal.
