Detailed ways

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

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 communication platform (High Altitude Platform Station, HAPS) communication system. Embodiments of the present disclosure are described by taking a satellite communication system as an example. Fig. 1 is an architecture diagram of a satellite communication system according to an exemplary embodiment. Referring to Figure 1, the satellite transmits beams through the antenna to form a satellite cell covered by the satellite network. Among them, the satellite is in a mobile state. Among them, the satellite cell can also be called Beam foot print. The coverage areas between the satellite cells may not overlap, may also partially overlap, or may also completely overlap. Satellite terminals can be deployed within the coverage of the satellite network. The satellite terminal located within the coverage of the satellite network communicates through the service link (Service link) between the satellite cell and the satellite. The satellite communicates with the ground infrastructure, such as the Gateway, through a feeder link, and then realizes interactive communication with the ground communication network, such as the core network and the data network.

Terminals referred to in embodiments of the present disclosure may include, but are not limited to: cellular and/or satellite radiotelephones with or without multi-line displays; personal Communications System (PCS) terminals; 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 and/or other devices including radio frequency transceivers. Wherein, the terminals involved in the embodiments of the present disclosure are sometimes called satellite terminals, wireless phones, or terminals, and may also be called terminal equipment, user equipment (User Equipment, UE), mobile station (Mobile Station, MS), mobile terminal ( Mobile Terminal, MT), etc.

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 devices, or ground base stations placed on aircraft that stay at high altitude for a long time. Wherein, the network device involved in the embodiments of the present disclosure may also be understood as one or more infrastructure units deployed in the satellite communication system. FIG. 2 and FIG. 3 respectively show architecture diagrams of a satellite communication system deployed with a base station involved in an exemplary embodiment of the present disclosure. In Figure 2, the base station (such as gNB in the 5G network) is independent of the satellite and gateway in the remote radio unit (Remote Radio Unit). The satellite terminal is connected to the base station through the air interface (uu), such as new radio (NR) uu, and is connected to the core network and the data network through the NG port for communication. Among them, the base station, satellite and gateway can be understood as NG radio access network (Radio Access Network, RAN). In Figure 3, the base station (such as gNB in the 5G network) can be deployed together with the satellite, and form the NG RAN with the gateway. The satellite terminal is connected to the base station through the air interface, and connected to the core network and the data network through the NG interface for communication.

In the NTN network, because the round-trip time (Round-Trip Time, RTT) is too large, the HARQ efficiency is reduced, so the feedback mechanism of closing part of the HARQ process is introduced in the feedback mechanism of the NTN network to improve the system feedback efficiency. In the feedback mechanism that shuts down part of the HARQ process, relevant terminal manufacturers have different opinions on whether to enhance the feedback HARQ codebook. Among them, the HARQ codebook includes Type-1 HARQ codebook, Type-2 HARQ and Type-3 HARQ codebook. Among them, the Type-1 HARQ codebook is also called a semi-static HARQ codebook, the Type-2 HARQ codebook is also called a dynamic codebook, and the Type-3 HARQ codebook is also called a one-shot (One-shot) HARQ codebook. The following takes the Type-3 HARQ codebook as an example for illustration. Wherein, 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.

Regarding the One-shot HARQ codebook, some terminal manufacturers claim not to support the One-shot HARQ codebook in the NTN network. Some terminal manufacturers advocate not to enhance the One-shot HARQ codebook, and believe that the HARQ results of the disabled HARQ process (disabled HARQ process) fed back by the terminal will help network equipment understand the decoding situation, so as to use more appropriate transmission parameters. In addition, the complexity of the terminal can also be simplified without enhancing the codebook. Some terminal manufacturers advocate enhancing the one-shot HARQ codebook. The main motivation is 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 HARQ process) activated by Radio Resource Control (RRC) configuration ), the One-shot HARQ codebook can be transmitted on the physical uplink control channel (Physical Uplink Control Channel, PUCCH)/physical uplink shared channel (Physical Uplink Shared Channel, PUSCH).

In related technologies, the transmission of the One-shot HARQ codebook on the PUSCH is triggered by downlink control information (DCI). Therefore, when the One-shot HARQ codebook is transmitted on the PUSCH, there is no corresponding DAI in the DCI. The value indicates whether to multiplex PUSCH to transmit One-shot HARQ codebook.

However, in the NTN network, different vendors 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 triggering the One-shot HARQ codebook feedback method, it may happen that the UE needs to perform One-shot HARQ codebook feedback on the PUSCH, but it is used for uplink scheduling For example, the DCI format 1-0 does not include the DAI field related to the one-shot codebook (that is, the information field used to indicate whether the PUSCH contains the one-shot codebook). Therefore, it is necessary to further improve the feedback method of the One-shot HARQ codebook.

An embodiment of the present disclosure provides a codebook feedback method. The network device configures One-shot HARQ codebook configuration information for the 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 flow chart showing a codebook feedback method according to an exemplary embodiment. As shown in Fig. 4, the codebook feedback method is used in a network device and includes the following steps.

In step S11, configure One-shot HARQ codebook configuration information.

In step S12, DAI indication information is sent.

In the embodiment of the present disclosure, the network device configures 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 .

Wherein, the trigger indication information may include DCI, for example, the DCI is used to trigger the terminal to perform One-shot HARQ codebook feedback. Among them, the network device can trigger the terminal to perform One-shot HARQ codebook feedback through DCI 0-1/DCI0-2.

In an implementation manner, the embodiments of the present disclosure may introduce a new information field in the DCI for sending DAI indication information. For example, introduce a new domain in DCI 0-1/0-2, say 3rd DAI, to send DAI indication information.

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

In one embodiment, the DAI indication information includes an information field for indicating whether the terminal multiplexes PUSCH resources and feeds back the One-shot HARQ codebook, which is hereinafter referred to as the first information field.

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

Wherein, the bits of the first information field can be 0 bits or 1 bits, wherein, when the terminal is not configured with a one-shot HARQ codebook by the network device, the first information field is 0 bits, and there is no need to report to the terminal at this time Send DAI indication information about one-shot HARQ codebook. When the terminal is configured with a one-shot HARQ codebook by the network device and the first information field is 1 bit, this bit indicates whether the terminal needs to feed back 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 multiplexes PUSCH resources and feeds back the One-shot HARQ codebook. For example, when the first information field bit value is 1, it indicates that the terminal Multiplex PUSCH resources to feed back the One-shot HARQ codebook. When the value of the bit in the first information field is 0, it indicates that the terminal does not multiplex PUSCH resources to feed back the One-shot HARQ codebook. Alternatively, when the bit value of the first information field is 0, it indicates that the terminal multiplexes the resource of PUSCH to feed back the One-shot HARQ codebook; when the bit value of the first information field is 1, it indicates that the terminal does not multiplex the resource of PUSCH Feedback One-shot HARQ codebook.

Wherein, the One-shot HARQ codebook fed back by the terminal may sometimes include or not include New Data Indicator (New Data Indicator, NDI) information.

In the codebook feedback method provided by the embodiments of the present disclosure, the DAI indication information sent by the network device to the terminal is used to indicate whether the terminal multiplexes PUSCH resources to feed back the One-shot HARQ codebook, and whether the One-shot HARQ codebook contains NDI information .

In the embodiments of the present disclosure, the information field used to indicate whether the terminal multiplexes PUSCH resources to feed back the One-shot HARQ codebook and whether the One-shot HARQ codebook contains NDI information is called the second information field. The DAI indication information includes a second information field, and the second information field is used to indicate whether the terminal multiplexes PUSCH resources to feed back the One-shot HARQ codebook, and whether the One-shot HARQ codebook contains NDI information.

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

Wherein, the bits in the second information field may be 0 bits or 2 bits. Wherein, when the terminal is not configured with a one-shot HARQ codebook by the network device, the second information field is 0 bits, and there is no need to send DAI indication information about the one-shot HARQ codebook to the terminal at this time. When the terminal is configured with a one-shot HARQ codebook by the network device and the second information field is 2 bits, this bit indicates whether the terminal needs to feed back the One-shot HARQ codebook in the PUSCH. Wherein, when the second information field is 2 bits, different bit values indicate whether the terminal multiplexes PUSCH resources to feed back the One-shot HARQ codebook, and/or whether the One-shot HARQ codebook contains NDI information. For example, when the bit value of the second information field is 10, it indicates that the One-shot HARQ codebook does not contain NDI information. When the bit value of the second information field is 01, it indicates that the One-shot HARQ codebook contains NDI information. When the bit value of the second information field is 00, it indicates that the resources of the PUSCH are not multiplexed to feed back the One-shot HARQ codebook. When the value of the bit in the second information field is not 0, it indicates that the resources of the multiplexed PUSCH are fed back to the One-shot HARQ codebook.

In the embodiment of the present 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 include the code of the unenhanced One-shot HARQ codebook This configuration information.

Wherein, in the embodiments of the present disclosure, for the convenience of description, the configuration information of the enhanced One-shot HARQ codebook is referred to as the first HARQ codebook configuration information. Wherein, the first HARQ codebook configuration information is used to configure the terminal to configure the codebook in the first codebook configuration manner. The codebook configuration information of the unenhanced One-shot HARQ codebook is called the second HARQ codebook configuration information. Wherein, the configuration information of the second HARQ codebook is used to configure the terminal to configure the codebook in the second codebook configuration manner. Wherein, the first codebook configuration mode can be understood as a HARQ codebook configuration mode 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 without enhancement. Wherein, the first codebook configuration manner can also be understood as an enhancement of the second codebook configuration manner.

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

Wherein, 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 showing a codebook feedback method according to an exemplary embodiment. The codebook feedback method may be executed alone, or may be executed in combination with other embodiments of the present disclosure. As shown in FIG. 5 , the codebook feedback method is used in network equipment and includes the following steps.

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

Wherein, the capability information sent by the terminal is used to indicate the HARQ codebook configuration mode supported by the terminal under the partial HARQ disabling mechanism.

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

In the embodiment of the present disclosure, the network device obtains the capability information of the terminal, and on the one hand, the terminal may send the capability information to the network device independently.

In one embodiment, when the terminal sends the capability information for indicating the HARQ codebook configuration capability supported by the terminal to the network device alone, it may design information dedicated to indicating the terminal's HARQ codebook configuration capability for the HARQ codebook. Hereinafter, the information dedicated to indicating the HARQ codebook configuration capability of the terminal for the HARQ codebook is referred to as first capability information. The network device acquires first capability information, where the first capability information is information dedicated to indicating the terminal's HARQ codebook configuration capability for the One-shot HARQ codebook.

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

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

On the other hand, the terminal may also send the capability information indicating the HARQ codebook configuration capability supported by the terminal to the network device together with other information. Wherein, other information may be understood as information other than HARQ codebook configuration capability information different from the HARQ codebook. In an example, the other information may also be understood as other signaling capable of carrying capability information of the HARQ codebook configuration capability supported by the terminal. Wherein, 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 different from the HARQ codebook can be carried in the same information and sent to the terminal. For example, the capability information for indicating the HARQ codebook configuration capability supported by the terminal may be carried in other signaling. Hereinafter, the information carrying the capability information indicating the HARQ codebook configuration capability supported by the terminal and other information is referred to as the second capability information.

In the embodiment of the present disclosure, 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 bits for indicating different HARQ codebook configuration capabilities, and different values of the bits explicitly indicate different HARQ codebook configuration capabilities. Or for another example, when the second capability information does not include the bit indicating different HARQ codebook configuration capabilities, it may be understood as implicitly indicating that the terminal supports the unenhanced HARQ codebook configuration capability.

In an 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 acquired by the network device includes the enhanced One-shot HARQ codebook, and includes information about other HARQ codebooks such as the Type-2 HARQ codebook and the Type-1 HARQ codebook.

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

In the embodiments 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 capability information indicating that the first codebook configuration mode is supported and sent by the terminal. On the other hand, when the terminal determines that the supported codebook configuration mode is the second codebook configuration mode, it does not send capability information to the network device. When the network device determines that the capability information is not received, determine that the terminal supports the second codebook configuration manner.

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

Wherein, the codebook configuration information of the One-shot HARQ codebook includes first HARQ codebook configuration information or second HARQ codebook configuration information.

In an implementation manner of an embodiment of the present disclosure, 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.
