Abstract

The invention provides a resource priority determining method, a resource priority processing device and system and UE. The resource priority determining method comprises the steps of performing energy detection on a physical sidelink control channel (PSCCH) to obtain a detection result and/or performing information decoding to obtain a decoding result; performing weighting processing on the detection result and/or the decoding result to determine the priority of a PSCCH resource, or determining the priority of the PSCCH resource according to the detection result and/or the decoding result. According to the invention, a problem of low utilization efficiency of resources in the related art is solved, and the effects of improving the resource utilization efficiency and reducing interference are achieved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a method for determining a resource priority, a processing device and system, and a UE. Background technique [0002] In a device-to-device (D2D) communication system of the related art, when there is a service to be transmitted between user equipment (User Equipment, UE), the service data between the UEs does not pass through the base station. Forwarding, but directly transmitted by the data source UE to the target UE through the air interface, such as figure 1 As shown in the figure, the wireless link between D2D UEs is called a side link, and the D2D communication mode is significantly different from the traditional cellular system communication mode. The wireless spectrum resources are saved, and the data transmission pressure of the core network is reduced, which can reduce the occupation of system resources, increase the spectrum efficiency of the cellular commun...
