Abstract

The invention discloses a side link communication terminal equipment cooperation information indication method, and the method comprises the following steps: determining a standby PSFCH resource set corresponding to a PSSCH, wherein the standby PSFCH resource set comprises special resources used for sending cooperation information, and the special resource and a PSFCH resource used for sending the HARQ information in the PSFCH resource configured by the system occupy different resource positions; and indicating the position of a special resource in the standby PSFCH resource set according to a special resource index, wherein the cooperation information is used for indicating that transmission resources occupied by the PSSCH sent by the first terminal device and the second terminal device have conflicts, or is used for indicating HARQ retransmission information sent by a third terminal device. The invention further discloses equipment for implementing the method. The problem that cooperation information cannot be sent in the prior art is solved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for indicating cooperative communication between terminal devices in an application scenario of side link communication. Background technique [0002] In inter-terminal communication, terminal A needs to send cooperation information to terminal B to help terminal B select appropriate transmission resources and avoid resource collisions with other terminals. Terminal A may be the destination receiving terminal of information sent by terminal B, or it may be another terminal. A possible solution is that the cooperation information sent by terminal A to terminal B may be carried by side link control information (SCI), MACCE, PC5-RRC or PSFCH. Among them, PSFCH carrying cooperative signaling has the advantage of low delay, and at the same time supports terminals without a channel monitoring function to provide cooperative information to...
