Background
In a mobile communication system, sidelink (sidelink), or called a sidelink, or an edge link, is used for direct transmission between terminals without passing through a network device. The terminal sends Sidelink Control Information (SCI) through a Physical Sidelink Control Channel (PSCCH), and schedules transmission of a Physical Sidelink Shared Channel (PSCCH) to send data. Here, sidelink transmission is performed based on broadcast, and the receiving end terminal does not feed back whether reception is successful or not unlike the transmitting end terminal.
The Sidelink transmission supports two resource allocation modes, one is a scheduling resource allocation (scheduled resource allocation) mode, and in the mode, the network equipment controls and allocates resources for each terminal; the other is an autonomous resource selection (autonomous resource selection) mode in which the terminal autonomously selects a resource.

An embodiment of the present invention provides a method for feeding back sidelink information, which is applied to a first terminal (a receiving terminal), and as shown in fig. 1, the method includes the following steps:
step 11: first transmission information related to a sidelink transmission is received.

Step 12: and feeding back second transmission information to the second terminal according to the first transmission information, wherein the second transmission information is used for indicating whether to perform receiving feedback on data sent by the second terminal.
After receiving the first transmission information, the first terminal feeds back second transmission information to the second terminal to inform the second terminal whether to receive and feed back the data sent by the second terminal, so that the feedback of the side link transmission is realized, and the reliability of the side link transmission is ensured.
Before step 11, the method further includes: a second terminal that establishes a sidelink transmission with the first terminal is determined. This step is to determine whether two terminals are capable of sidelink transmission, and is preferably implemented by, but not limited to: and determining a terminal which belongs to the same interest group as the first terminal as the second terminal according to at least one item of the following target information. Wherein, the target information includes but is not limited to:
1. and the interactive information of an application layer or a control layer. For example, the terminals ensure that two terminals can be in an interest group at the V2X level by interacting with the application layer of V2X or the control function (control function) layer of V2X, in a manner similar to that of (discover) mechanism found in sidelink transmission in the LTE system, and ensure that services can be understood by using the same encryption and decryption process. Such as by a service-independent service ID.
2. The air interface transmits information. For example, two terminals send over-the-air information, such as discovery (discovery) signals/information (message) or data communication (data communication) signals/information, at the air interface, and discovery that the two terminals are in the same interest group and are closer to each other at the air interface is implemented at the sidelink air interface.
3. Discovery signals/information or data transmission signals/information. For example, in discovery signals/information or transmission signals/information carrying: a group identity of the interest group, a terminal identity of each terminal (per UE) within the group, etc. Wherein the terminal id can be used for the two terminals to perform further sidelink transmission and feedback negotiation. For example, in two terminals, the group identifier of the first terminal is X, the first terminal identifier is UE identifier 1, the group identifier of the second terminal is X, and the second terminal identifier is UE identifier 2.
4. Indication information of the network device in such a way that the terminal can discover the discovery of the terminal performing the sidelink transmission with the assistance or the indication of the network device. For example, if the network device knows that the two terminals are close to each other, it may directly indicate that the two terminals can perform sidelink transmission.
In this embodiment of the present invention, the second transmission information includes: at least one of a group identifier of an interest group to which the first terminal and the second terminal belong, a first terminal identifier of the first terminal, a second terminal identifier of the second terminal, feedback indication information whether to perform feedback reception, second transmission resource information related to the feedback reception, and identification information related to the feedback reception.
The first terminal and the second terminal belong to the same interest group, services transmitted between the first terminal and the second terminal can be understood by adopting the same encryption and decryption processes, and the transmitted services can be distinguished by independent service identifiers. The first terminal identifier is used to represent identity information of the first terminal, and the first terminal identifier may be a terminal ID, an RNTI, and the like of the first terminal. The second terminal identifier is used to represent identity information of the second terminal, and the second terminal identifier may be a terminal ID, an RNTI, and the like of the second terminal.
The second transmission resource information is used for indicating the position and the size of the transmission resource related to the side link transmission feedback. If the first terminal sends second transmission resource information used for indicating resources used for receiving feedback to the second terminal, implicitly indicating that the first terminal can carry out receiving feedback on the received data; and if the second transmission resource information is not sent, implicitly indicating that the first terminal does not receive feedback on the received data. Wherein the resource indicated by the second transmission resource information is determined from a data communication feedback resource pool. For example, the second terminal transmits first transmission information carrying the group identifier X, UE identifier 1 as a destination address, the UE identifier 2 as a source address, and which resource selected from a data communication resource pool (data communication pool) it desires to transmit to the first terminal, and may also carry information such as Modulation and Coding Scheme (MCS) capability, Multiple Input Multiple Output (MIMO) capability, bandwidth, Sub-Carrier Spacing (SCS) it desires, and the like. After receiving the first transmission information, the first terminal uses second transmission information carrying group identifier X, UE identifier 1 as a source address, UE identifier 2 as a destination address, and which resource selected from a data communication feedback resource pool (data communication feedback pool) is desired to perform feedback of ACK or feedback of MCS. The information fed back may include, but is not limited to: the feedback includes information such as a Physical Uplink Control Channel-like format (PUCCH-like format), a timing relationship, a Hybrid automatic repeat Request code book (HARQ code book), and the like. Therefore, the first terminal and the second terminal perform one negotiation equivalently, and subsequent communication is facilitated.

For example, the second terminal sends the first transmission information carrying the group identifier X, UE id 2 as the source address, the UE identifier 1 as the destination address, and the resource selected in which data communication pool to communicate with, to the first terminal, and the first terminal sends the second transmission information carrying the group identifier X, UE id 1 as the source address, the UE identifier 2 as the destination address, and the second transmission information used to indicate that i receive this information and that i will also allocate a UE identifier (e.g., UE identifier 1') for the feedback resource alone. Wherein this UE identity 1' is used for the transmission of scrambled feedback information, wherein the resource of the feedback information may select one from the datacom feedback pool. The second terminal needs to demodulate the UE identity 1 ' to judge whether the first terminal has feedback, if not, the first terminal is considered not to feed back, and if the UE identity 1 ' is demodulated, the second terminal determines the first terminal to feed back according to the demodulated UE identity 1 '. The resources and specific information of the feedback information of this method are also scheduled, so the configuration for scheduling these feedback information needs to be negotiated, such as negotiating the location and identification of the feedback scheduled resources. And then the terminal monitors the feedback scheduling information to determine whether the feedback exists.
And the first transmission resource information and the second transmission resource information have a preset corresponding relation. For example, the second terminal sends the first transmission information carrying the group identity X, UE identity 2 as the source address, the UE identity 1 as the destination address, and the resource selected in which data communication pool it wishes to communicate. The first terminal uses the identifier 1 carrying the group identifier X, UE as the source address, the UE identifier 2 as the destination address, and the second transmission information indicating that the information is received and can be fed back according to the first transmission information. The specific feedback resource may have a default mapping relationship with the resource selected in the datacom pool, that is, the second transmission resource information is determined according to the first transmission resource information.
The method for feeding back the sidelink information at the first terminal side is introduced above, and the method for feeding back the sidelink information at the second terminal side will be further explained with reference to the drawings.

The first transmission resource information of the embodiment of the present invention includes, but is not limited to: at least one of resource information selected from a data communication resource pool, hybrid automatic repeat request, HARQ, process number information, reference signal configuration information of RLM, reference signal configuration information of beam management, and antenna transmission mode information.

And the second terminal determines whether the first terminal receives and feeds back the data sent by the second terminal according to the second transmission information, so that the feedback of the side link transmission is realized, and the reliability of the side link transmission is ensured.
Wherein, step 21 also includes before: a first terminal that establishes a sidelink transmission with a second terminal is determined. Wherein, this step includes: determining a terminal which belongs to the same interest group as the second terminal as the first terminal according to at least one item of the following target information; wherein, the target information includes but is not limited to:

Such as by a service-independent service ID.
The air interface transmits information; for example, two terminals send air interface transmission information at an air interface, such as a discovery signal/information or a data transmission signal/information, and discovery that the two terminals are in the same interest group and are closer to each other at the air interface is achieved at a sidelink air interface.
Discovery signals/information or data transmission signals/information; for example, in discovery signals/information or transmission signals/information carrying: a group identification of the interest group, a terminal identification of each terminal within the group, etc. Wherein the terminal id can be used for the two terminals to perform further sidelink transmission and feedback negotiation. For example, in two terminals, the group identifier of the first terminal is X, the first terminal identifier is UE identifier 1, the group identifier of the second terminal is X, and the second terminal identifier is UE identifier 2.
Indication information of the network device. The method is that the terminal can discover the discovery of the terminal which conducts the sidelink transmission under the assistance or the instruction of the network equipment. For example, if the network device knows that the two terminals are close to each other, it may directly indicate that the two terminals can perform sidelink transmission.

The first terminal and the second terminal belong to the same interest group, and services transmitted between the first terminal and the second terminal can be mutually understood by adopting the same encryption and decryption processes. The first terminal identification is used for representing the identity information of the first terminal, and the second terminal identification is used for representing the identity information of the second terminal.

Wherein the identification information related to receiving the feedback refers to: identification information associated with the second transmission resource information. The second terminal needs to demodulate the identification information to judge whether the first terminal has feedback, if not, the first terminal is considered not to feed back, and if the identification information is demodulated, the second terminal determines the first terminal to feed back according to the demodulated identification information.
The first transmission resource information and the second transmission resource information have a preset corresponding relation, and the second transmission resource information for feedback is determined according to the first transmission resource information.
In the side link information feedback method of the embodiment of the invention, the receiving terminal receives first transmission information related to side link transmission, and feeds back second transmission information to the sending terminal according to the first transmission information to indicate whether to feed back data sent by the sending terminal, so that the receiving terminal can receive and feed back the data transmitted by the sending terminal, and the reliability of data transmission in the side link transmission process is ensured.
