[0073] See figure 1 , figure 1 is a flow chart of an information indication method provided by an embodiment of the present application, the method is applied to a terminal, such as figure 1 As shown, the method includes the following steps:

[0074] Step 101: Obtain control signaling.

[0075] In this embodiment, the control signaling may be UL DCI or higher layer signaling. It should be noted that the UL DCI may be sent to the terminal by a network device such as a base station. UL DCI may be received by the terminal from the base station. High-level signaling can be obtained through any of the following methods: base station configuration, pre-configuration, protocol pre-definition, other terminal instructions, etc. For example, the high-level signaling can be obtained through pre-configuration.

[0076] Step 102: Determine relevant information of SL feedback information according to the control signaling.

[0077] Optionally, the control signaling is used to indicat...

Embodiment approach

[0113] In one embodiment, the existing DAI field in the UL DCI can be used to indicate SAI. If it is a semi-static codebook, the DAI field can be used to indicate 1-bit SAI; and if it is a dynamic codebook, the DAI field can be used to indicate 2-bit SAI.

[0114] In another embodiment, the existing DAI field in the UL DCI can be used to indicate SAI. If it is a semi-static codebook, the first DAI field can contain 1 or 2 bits of SAI. If it is a dynamic codebook, the first DAI field can contain 2 bits. SAI; in addition, if it is a dynamic codebook and there are two sub-codebooks, the second DAI field does not indicate SAI.

[0115] In another implementation, the UL DCI includes the DAI domain and the SAI domain: for the SAI domain, if it is a semi-static codebook and at least one of the following is satisfied: SL CG type1 is configured, SL CG type2 is configured, and activated SL CG type2, configured to monitor SL DCI, contains 1 bit. Preferably, if it is a semi-static codebo...

[0198] At present, when implementing SL feedback, the time offset value used to determine the time domain resource of SL feedback information generally includes a dynamic time offset value and a semi-static time offset value. And the two types of time offset values ​​are usually respectively configured or pre-configured or indicated or defined by a protocol through different signaling. For a time-domain resource of SL feedback information (such as PUCCH or PUSCH), the number of bits of the SL feedback information is related to or the time offset value associated with the time-domain resource. If the dynamic time offset value and the semi-static time offset value are different, only the SL feedback information of the dynamic time offset value is associated, and only the SL feedback information of the semi-static time offset value is associated with the dynamic time offset value The SL feedback information of the semi-static time offset value and the semi-static time offset valu...

Abstract

The invention discloses an information indication method and device, an information determination method and device and communication equipment, and belongs to the technical field of communication. The information indication method comprises the following steps: acquiring a control signaling; according to the control signaling, determining related information of bypass SL feedback information, wherein the control signaling comprises at least one of a first parameter domain and a DAI domain, the first parameter domain is used for indicating related information of SL feedback information, and the DAI domain is used for indicating related information of SL feedback information or related information of Uu feedback information; the control signaling is UL DCI or high-level signaling. According to the embodiment of the invention, by means of the related information of the SL feedback information, the terminal and network equipment such as a base station can be helped to keep consistent understanding of the SL feedback information (such as an SL codebook), so that the reliability of the SL feedback information is enhanced.

Description

technical field [0001] The present application belongs to the technical field of communication, and in particular relates to an information indication and information determination method, device and communication equipment. Background technique [0002] In order to improve the reliability and resource utilization of data transmission on the sidelink (SL), feedback mechanisms such as the Hybrid Automatic Repeat reQuest (HARQ) feedback mechanism have also been introduced into the SL technology. After receiving the SL data, the user can feed back SL HARQ-ACK information to the network device on the corresponding channel to indicate whether the SL data transmission is successful or failed. However, currently there is no corresponding method to ensure that the understanding of the SL feedback information by the terminal and the network device is consistent, which affects the reliability of the SL feedback information. Contents of the invention [0003] The purpose of the embo...
