Technical Field

Background

In the related art, a partial hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback disabling mechanism is introduced to improve system efficiency. For example, a mechanism for closing part of HARQ process feedback is introduced in a feedback mechanism for Non-terrestrial network (Non-terrestrial networks, NTN) to improve system efficiency.

Based on the HARQ feedback disabling mechanism, different terminal manufacturers have different claims at present when the codebook feedback of the HARQ is carried out. Some manufacturers claim not to enhance the HARQ codebook, so that the network device can know the decoding condition by using the HARQ result of the forbidden HARQ process fed back by the terminal, thereby using more appropriate transmission parameters, not enhancing the HARQ codebook, and also simplifying the complexity of the UE. Some manufacturers claim to enhance the HARQ codebook to reduce the size of the HARQ codebook, thereby reducing redundant information and interference caused by unnecessary uplink transmission.

Detailed Description

Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The codebook feedback method provided in the embodiments of the present disclosure is applied to NTN networks, for example, to satellite communication systems, or high-altitude communication platform (High Altitude Platform Station, HAPS) communication systems. The embodiments of the present disclosure will be described with reference to a satellite communication system. Fig. 1 is a block diagram of a satellite communication system architecture according to an exemplary embodiment. Referring to fig. 1, satellites transmit beams through antennas to form satellite cells covered by a satellite network. Wherein the satellite is in motion. The satellite cell may also be referred to as a Beam spot print. The coverage areas between satellite cells may be non-overlapping, may be partially overlapping, or may be fully overlapping. The satellite terminals may be deployed within the coverage of a satellite network. Satellite terminals located within the coverage of the satellite network communicate via Service links (Service links) between satellite cells and satellites. The satellite communicates with a ground infrastructure, such as a Gateway (Gateway), via a Feeder link, thereby enabling interactive communication with a ground communication network, such as a core network and a Data network (Data network).

The terminals involved in the embodiments of the present disclosure may include, but are not limited to: cellular and/or satellite radiotelephones with or without a multi-line display; a Personal Communications System (PCS) terminal that may combine radiotelephone and data processing, facsimile and/or data communications capabilities; personal Digital Assistants (PDAs) including radio frequency transceivers and pagers, internet/intranet access, web browsers, organizers, calendar and/or Global Positioning System (GPS) receivers; and/or other devices including radio frequency transceivers. The Terminal according to the embodiments of the present disclosure may be referred to as a satellite Terminal, a wireless phone, or a Terminal, and may also be referred to as a Terminal device, a User Equipment (UE), a Mobile Station (MS), a Mobile Terminal (MT), or the like.

The network devices involved in the embodiments of the present disclosure may be, but are not limited to, wireless base stations, satellite base stations, wireless transceiver devices, or ground base stations, etc., that are placed on an aircraft that is left aloft for a long period of time. The network device to which embodiments of the present disclosure relate may also be understood as one or more infrastructure elements deployed in a satellite communication system. Fig. 2 and 3 respectively show a satellite communication system architecture diagram with a base station deployed in an exemplary embodiment of the present disclosure. In fig. 2, the base station (e.g., the gNB in the 5G network) is independent of the satellites and gateways in the remote wireless access unit (Remote Radio Unit). The satellite terminals access the base station via an air interface (uu), e.g., new Radio (NR), and connect to the core network and to the data network via an NG interface for communication. Among other things, the base station, satellite and gateway can be understood as NG radio access network (Radio Access Network, RAN). In fig. 3, a base station (e.g., a gNB in a 5G network) may be deployed with a satellite and organized with a gateway as an NG RAN. The satellite terminal is connected to the base station through an air interface and is connected to the core network and the data network through an NG interface for communication.

In the NTN network, since the Round-Trip Time (RTT) is too large, which results in the decrease of HARQ efficiency, a feedback mechanism for closing part of HARQ processes is introduced into a feedback mechanism of the NTN network, so as to improve the feedback efficiency of the system. In the feedback mechanism of closing part of the HARQ process, the relevant terminal manufacturer has different claims on whether the feedback HARQ codebook is enhanced. The HARQ codebook comprises a Type-1HARQ codebook, a Type-2HARQ codebook and a Type-3HARQ codebook. The Type-1HARQ codebook is also referred to as a semi-static HARQ codebook, the Type-2HARQ codebook is also referred to as a dynamic codebook, and the Type-3HARQ codebook is also referred to as a One-shot (One-shot) HARQ codebook. The Type-3HARQ codebook is described below as an example. In the following embodiments of the present disclosure, the Type-3HARQ codebook and the One-shot HARQ codebook are sometimes used alternately, and those skilled in the art should understand the consistency of the meaning.

Aiming at the One-shot HARQ codebook, some terminal manufacturers claim that the One-shot HARQ codebook is not supported in the NTN network. Some terminal manufacturers claim not to enhance the One-shot HARQ codebook, and consider that the terminal feeds back the HARQ result of the unactivated HARQ process (disabled HARQ process) to help the network device to know the decoding condition, so that more appropriate transmission parameters are used. In addition, the complexity of the terminal can be simplified without enhancing the codebook. Some terminal manufacturers claim to enhance the One-shot HARQ codebook, and the main motivation is to reduce the size (size) of the One-shot HARQ codebook, thereby reducing processing overhead (overhead) and interference caused by unnecessary uplink transmission. The enhancement scheme consistency ratio is converged aiming at the enhancement of the One-shot HARQ codebook, and mainly comprises the following steps: the One-shot HARQ codebook contains a HARQ process (configured enabled HARQ process) activated by radio resource control (Radio Resource Control, RRC) configuration, and the One-shot HARQ codebook can be transmitted on a physical uplink control channel (Physical Uplink Control Channel, PUCCH)/physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

In the related art, the on-shot HARQ codebook is triggered and activated by downlink control information (Downlink control information, DCI) on PUSCH, so when the on-shot HARQ codebook is transmitted on PUSCH, no corresponding DAI value in DCI indicates whether to multiplex the PUSCH to transmit the on-shot HARQ codebook.

However, in NTN networks, different vendors have different claims on whether One-shot HARQ codebooks are enhanced. By means of feedback mode of the downlink scheduling DCI, for example, DCI format 1-1 triggering One-shot HARQ codebook, it is possible that UE needs to perform One-shot HARQ codebook feedback on PUSCH, but DCI for uplink scheduling, for example, DCI format 1-0, does not include DAI field related to One-shot codebook (i.e. information field for indicating whether PUSCH includes One-shot codebook). Therefore, a feedback scheme of the One-shot HARQ codebook needs to be further improved.

The embodiment of the disclosure provides a codebook feedback method, wherein network equipment configures One-shot HARQ codebook configuration information for a terminal and sends DAI indication information so as to introduce the DAI indication information into the One-shot HARQ codebook feedback technology.

Fig. 4 is a flowchart illustrating a codebook feedback method according to an exemplary embodiment, as shown in fig. 4, for use in a network device, including the following steps.

In step S11, one-shot HARQ codebook configuration information is configured.

In step S12, DAI indication information is transmitted.

In the embodiment of the disclosure, the network device configures the One-shot HARQ codebook configuration information for the terminal, and the terminal can perform One-shot HARQ codebook feedback.

In One embodiment, 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.

The triggering indication information may include DCI, for example, the DCI triggers the terminal to perform One-shot HARQ codebook feedback. The network equipment can trigger the terminal to perform One-shot HARQ codebook feedback through DCI 0-1/DCI 0-2.

In one implementation, embodiments of the present disclosure may introduce a new information field in the DCI for transmitting the DAI indication information. For example, a new field, such as 3rd DAI, is introduced in DCI 0-1/0-2 to transmit DAI indication information.

In the codebook feedback method provided by the embodiment of the disclosure, DAI indication information sent by the network equipment to the terminal is used for indicating whether the terminal multiplexes the resources of the PUSCH and feeding back the One-shot HARQ codebook.

In One embodiment, the DAI indication information includes a resource for indicating whether the terminal multiplexes PUSCH, and an information field of the feedback One-shot HARQ codebook, hereinafter referred to as a first information field.

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

The bit of the first information field may be 0 bit or 1 bit, where when the terminal is not configured with the one-shot HARQ codebook by the network device, the first information field is 0 bit, and at this time, no DAI indication information about the one-shot HARQ codebook needs to be sent to the terminal. When the terminal is configured with One-shot HARQ codebook by the network equipment and the first information field is 1 bit, indicating whether the terminal needs to feed back the One-shot HARQ codebook in the PUSCH or not by the bit. When the first information field is 1 bit, different bit values indicate whether the terminal multiplexes the PUSCH resources, and feed back the One-shot HARQ codebook, for example, when the bit value of the first information field is 1, the terminal is instructed to multiplex the PUSCH resources and feed back the One-shot HARQ codebook, and when the bit value of the first information field is 0, the terminal is instructed not to multiplex the PUSCH resources and feed back the One-shot HARQ codebook. Or the method can also be a resource feedback One-shot HARQ codebook for indicating the terminal to multiplex the PUSCH when the bit value of the first information domain is 0, and indicating the terminal not to multiplex the resource feedback One-shot HARQ codebook of the PUSCH when the bit value of the first information domain is 1.

The One-shot HARQ codebook fed back by the terminal may or may not include new data indication (New Data Indicator, NDI) information.

In the codebook feedback method provided by the embodiment of the disclosure, the DAI indication information sent by the network device to the terminal is used for indicating whether the terminal multiplexes the resource feedback One-shot HARQ codebook of the PUSCH and whether the One-shot HARQ codebook contains NDI information.

In the embodiment of the disclosure, an information field for indicating whether a terminal multiplexes a resource feedback One-shot HARQ codebook of PUSCH and whether the One-shot HARQ codebook includes NDI information is referred to as a second information field. The DAI indication information comprises a second information field, wherein the second information field is used for indicating whether the terminal multiplexes the resource feedback One-shot HARQ codebook of the PUSCH and whether the One-shot HARQ codebook contains NDI information.

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

The bits of the second information field may be 0 bits or 2 bits. When the terminal is not configured with the one-shot HARQ codebook by the network equipment, the second information field is 0 bit, and DAI indication information about the one-shot HARQ codebook does not need to be sent to the terminal at the moment. When the terminal is configured with the One-shot HARQ codebook by the network equipment and the second information field is 2 bits, indicating whether the terminal needs to feed back the One-shot HARQ codebook in the PUSCH or not through the bits. When the second information field is 2 bits, different bit values indicate whether the terminal multiplexes the resource feedback One-shot HARQ codebook of the PUSCH and/or whether the One-shot HARQ codebook contains NDI information. For example, when the second information field bit has a value of 10, it indicates that the One-shot HARQ codebook does not contain NDI information. And when the bit value of the second information field is 01, indicating that the One-shot HARQ codebook contains NDI information. And when the bit value of the second information domain is 00, indicating that the resource feedback One-shot HARQ codebook of the PUSCH is not multiplexed. And when the bit value of the second information domain is not 0, indicating the resource feedback One-shot HARQ codebook of the multiplexing PUSCH.

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

For convenience of description in the embodiment of the present disclosure, the configuration information of the enhanced One-shot HARQ codebook is referred to as first HARQ codebook configuration information. The first HARQ codebook configuration information is used for configuring a codebook configured by the terminal in a first codebook configuration mode. The codebook configuration information of the One-shot HARQ codebook which is not enhanced is referred to as second HARQ codebook configuration information. The configuration information of the second HARQ codebook is used for configuring the codebook by the configuration terminal in the first codebook configuration mode. The first codebook configuration mode may be understood as an HARQ codebook configuration mode corresponding to the matching enhanced HARQ codebook configuration capability. The second codebook configuration may be understood as a HARQ codebook configuration that matches the HARQ codebook configuration capability that is not enhanced. The first codebook configuration may also be understood as an enhancement to the second codebook configuration.

The codebook configuration manner included in the first codebook configuration manner in the embodiment of the present disclosure may include One or more types, for example, may include One or more types of enhancement schemes for One-shot HARQ codebooks in the related art. The codebook configuration means included in the second codebook configuration means may also include one or more.

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.

Fig. 5 is a flow chart illustrating a codebook feedback method according to an exemplary embodiment, which may be performed alone or in combination with other embodiments of the present disclosure. As shown in fig. 5, the codebook feedback method is used in a network device, and includes the following steps.

In step S21, capability information transmitted by the terminal is received.

The capability information sent by the terminal is used for indicating an HARQ codebook configuration mode supported by the terminal under the condition of adopting a partial HARQ disabling mechanism.

In the embodiment of the disclosure, the terminal may send capability information indicating 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 equipment acquires capability information sent by the terminal.

In the embodiment of the disclosure, the network device acquires the capability information of the terminal, and on one hand, the terminal can independently send the capability information to the network device.

In one embodiment, when the terminal separately transmits 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 may be designed. The information dedicated to indicating the HARQ codebook configuration capability of the terminal for the HARQ codebook will be referred to as first capability information hereinafter. The network equipment acquires first capability information, wherein the first capability information is information special for indicating the HARQ codebook configuration capability of the terminal aiming at the One-shot HARQ codebook.

In an example, assume that the One-shot HARQ codebook supported by the terminal is an 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 HARQ codebook configuration capability of the terminal for the One-shot HARQ codebook.

In an example, in the NTN network, the network device may acquire the information element (information element, IE) including the first capability information, which is reported by the terminal, as follows:

NTN-r17::＝SEQUENCE{

ul-maximumHARQProcessNumber-r17 ENUMERATED {supported}OPTIONAL,

enhancedone-shot-r17 ENUMERATED {supported}OPTIONAL。

on the other hand, the terminal may also transmit capability information indicating HARQ codebook configuration capabilities supported by the terminal to the network device along with other information. The other information may be understood as information other than HARQ codebook configuration capability information other than the HARQ codebook. In an example, this other information may also be understood as other signaling capable of carrying capability information of the HARQ codebook configuration capability supported by the terminal. The capability information for indicating the HARQ codebook configuration capability supported by the terminal and other information than the HARQ codebook configuration capability information different from the HARQ codebook may be carried in the same information and sent to the terminal. For example, capability information indicating HARQ codebook configuration capability supported by the terminal may be carried in other signaling. The information carrying capability information indicating HARQ codebook configuration capability supported by the terminal and other information will be referred to as second capability information hereinafter.

In the embodiment of the disclosure, the network device acquires 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 the different HARQ codebook configuration capabilities are explicitly indicated by different values of the bit. Or, for another example, when no bit indicating a different HARQ codebook configuration capability is included in the second capability information, it may be understood as an implicit indication that the terminal supports the HARQ codebook configuration capability that is not enhanced.

In an example, assume 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 and acquired by the network equipment comprises an enhanced One-shot HARQ codebook and related information of other HARQ codebooks such as a Type-2 HARQ codebook and a Type-1 HARQ codebook.

In an example, in the NTN network, information element including the second capability information reported by the terminal acquired by the network device may be as follows:

NTN-r17::＝SEQUENCE{

ul-maximumHARQProcessNumber-r17 ENUMERATED {supported}OPTIONAL，

enhancedHARQcodebook-r17 ENUMERATED {supported}OPTIONAL。

in the embodiment of the present disclosure, on the one hand, the terminal may send the capability information to the network device when it is determined that the supported codebook configuration mode is the first codebook configuration mode. The network equipment receives capability information which is sent by the terminal and indicates to support the first codebook configuration mode. On the other hand, the terminal does not send the capability information to the network device when the supported codebook configuration mode is determined to be the second codebook configuration mode. And the network equipment determines that the terminal supports the second codebook configuration mode under the condition that the network equipment determines that the capability information is not received.

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

Fig. 6 is a flow chart illustrating a codebook feedback method according to an exemplary embodiment, which may be performed alone or in combination with other embodiments of the present disclosure. As shown in fig. 6, the codebook feedback method is used in a network device, and includes the following steps.

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

In the embodiment of the disclosure, the network equipment acquires the capability information sent by the terminal, and the capability information is used for indicating the configuration capability of the One-shot HARQ codebook supported by the terminal, so that the network equipment can configure the configuration information of the One-shot HARQ codebook for the terminal based on the capability information.

The codebook configuration information of the One-shot HARQ codebook comprises first HARQ codebook configuration information or second HARQ codebook configuration information.

In One implementation manner of the embodiment of the disclosure, the network device determines, based on capability information of the terminal, that the terminal supports a first codebook configuration manner, and the One-shot HARQ codebook configuration information configured for the terminal is first HARQ codebook configuration information or second HARQ codebook configuration information.

In another implementation manner of the embodiment of the present disclosure, the network device determines, based on capability information of the terminal, that the terminal supports the second codebook configuration manner, where the One-shot HARQ codebook configuration information configured for the terminal is the second HARQ codebook configuration information.

In the codebook feedback method provided by the embodiment of the disclosure, based on the HARQ codebook configuration capability supported by the terminal, the network device may configure the first HARQ codebook configuration information or the second HARQ codebook configuration information for the terminal, and the terminal configures the codebook by adopting a codebook configuration mode corresponding to the configured codebook configuration information.

In the embodiment of the disclosure, the network device configures codebook configuration information of the One-shot HARQ codebook for the terminal, and the first HARQ codebook configuration information or the second HARQ codebook configuration information can be configured and used through RRC information.

In an example, whether One-shot HARQ enhancement codebook is used is configured by RRC. The enhancement codebook of One-shot HARQ codebook is for example called: enhanced type-3HARQ codebook. If the terminal supports One-shot HARQ enhancement codebook, the configuration terminal generates codebook and feedback according to the enhancement codebook mode, such as feeding back only the activated HARQ process (enabled HARQ process). If the terminal does not support the One-shot HARQ enhancement codebook, feeding back according to the One-shot HARQ codebook of the related technology.

In an example, an example of configuring One-shot HARQ enhancement codebook through RRC information is as follows:

PhysicalCellGroupConfig::＝ SEQUENCE{

In step S41, one-shot HARQ codebook configuration information is received, and DAI indication information is received.

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

In the embodiment of the disclosure, the terminal can receive the One-shot HARQ codebook configuration information through the RRC information.

In one implementation, embodiments of the present disclosure may introduce a new information field in the DCI for receiving the 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.

In one embodiment, the DAI indication information includes a first information field.

When the second information field is 0 bit, the terminal does not need to send DAI indication information, and the terminal can be understood as implicit indication terminal does not need to feed back One-shot HARQ codebook. And when the second information field is 2 bits, indicating that the terminal needs to feed back the One-shot HARQ codebook. When the second information field is 2 bits, different bit values indicate whether the terminal multiplexes the resource feedback One-shot HARQ codebook of the PUSCH and/or whether the One-shot HARQ codebook contains NDI information.
