Embodiment Construction
[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0039] In SL communication, the introduction of cooperative resource allocation between terminals is considered to reduce transmission collision problems caused by hidden nodes and half-duplex restrictions in resource allocation modes independently selected by terminals. At present, it is considered that the sending of cooperation information between ...

The invention discloses a configuration method for sending cooperation information between sidelink terminals. The method comprises the following steps: cooperation information for assisting terminals to perform resource selection or resource reselection in sidelink communication, wherein the cooperation information has a transmission priority, and the configuration parameter of the cooperation information corresponds to the transmission priority of the cooperation information. The invention further comprises a device applying the method. According to the invention, the problem that the existing method and device cannot determine the priority rule of the terminal cooperation information and send the configuration parameters is solved, and the method and device are especially suitable for a mobile communication system.
Description
technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a method and device for sending and configuring cooperation information between side link terminals. Background technique [0002] In side link communication, the resources used by cooperative terminals to send cooperation information may include the following methods: resources indicated in the cooperation request information; resources independently selected by cooperative terminals based on interception; cooperative terminals request resources from the base station for sending Coordination information: high-level configuration resources bound to terminal ID or sub-channel ID, that is, cooperative terminals can send cooperation information through resources bound to terminal ID or sub-channel ID, similar to the existing NR (new air interface) system The PSFCH (Physical sidelink feedback channel, physical sidelink feedback channel) channel. At present...
