Embodiment approach 1

[0097] This embodiment mainly describes that when the UE at the transmitting end and the UE at the receiving end perform sidelink transmission through the autonomous resource selection mode, the UE at the transmitting end allocates the first resource, sends indication information to the UE at the receiving end, and receives feedback sent by the UE at the receiving end information process. like Figure 4 As shown, the resource indication method provided by the embodiment of the present invention may include the following steps 401-405.

[0098] Step 401, the UE at the sending end determines the first resource.

[0099] Step 402, the UE at the sending end sends first indication information to the UE at the receiving end.

[0100] Step 403, the UE at the receiving end receives the first indication information.

[0101] Step 404, the UE at the receiving end sends first feedback information to the UE at the transmitting end on the first resource.

[0102] Step 405, the sending ...

Embodiment approach 2

[0129] This embodiment mainly describes that when the UE at the transmitting end and the UE at the receiving end perform sidelink transmission through the scheduling resource allocation mode, the control node allocates the first resource and sends indication information to the UE at the transmitting end, so that the UE at the transmitting end forwards the information to the UE at the receiving end. Indication information, and the process of receiving feedback information from the UE at the receiving end to the UE at the sending end. like Figure 6 As shown, the resource indication method provided by the embodiment of the present invention may include the following steps 601-608.

[0130] Step 601, the control node determines the first resource.

[0131] Step 602, the control node sends fifth indication information to the UE at the sending end.

[0132] Step 603, the sending end UE receives the fifth indication information.

[0133] Step 604, the UE at the transmitting end d...

Embodiment approach 3

[0157] This embodiment mainly describes that when the UE at the transmitting end and the UE at the receiving end perform sidelink transmission through the scheduling resource allocation mode, the control node allocates the first resource and sends indication information to the UE at the receiving end, so that the UE at the receiving end can send process of feedback. like Figure 7 As shown, the resource indication method provided by the embodiment of the present invention may include the following steps 701-705.

[0158] Step 701, the control node determines the first resource.

[0159] Step 702, the control node sends the first indication information to the receiving end UE.

[0160] Step 703, the UE at the receiving end receives the first indication information.

[0161] Step 704, the UE at the receiving end sends the first feedback information to the control node on the first resource.

[0162] Step 705, the control node receives the first feedback information.

Abstract

The embodiment of the invention discloses a resource indication method, device and system, relates to the technical field of communication, and aims to solve the problem that transmission resources reserved by receiving end UE conflict with transmission resources reserved by sending end UE. The method is applied to a process of adopting sidelink transmission, and comprises the steps that first equipment determines a first resource, wherein the first resource is used for transmitting first feedback information, and the first equipment sends first indication information to second equipment, wherein the first indication information is used for indicating the first resource. The method can be applied to a scene in which a control node or a sending end UE indicates a resource for transmitting feedback information for a receiving end UE.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource indication method, device and system. Background technique [0002] In a Long Term Evolution (Long Term Evolution, LTE) system, user equipment (User Equipment, UE) can directly perform data transmission by using a sidelink (sidelink) technology without going through a network device. [0003] Currently, when the UE at the transmitting end is in the autonomous resource selection mode (that is, the UE at the transmitting end allocates transmission resources autonomously), the UE at the transmitting end can reserve Physical Sidelink Shared Channel (PSSCH) resources for it, and the UE at the transmitting end The UE can directly send data to the UE at the receiving end through the PSSCH resource without using a network device. [0004] However, in the New Radio (NR) system, after the receiving UE receives the data sent by the transmi...
