Abstract

The purpose of the present invention is to provide a method, device and system for determining communication resources of a D2D pair. The method according to the present invention includes: acquiring first related information corresponding to the D2D pair, second related information corresponding to the device to be selected, and third related information corresponding to the base station; based on the first 1. The second and third relevant information, combined with the first SINR threshold corresponding to the receiving end of the D2D pair, and the second SINR threshold corresponding to the base station, to determine the Whether the D2D pair satisfies the predetermined condition; when the D2D pair satisfies the predetermined condition, select the communication resource of the device to be selected and allocate it to the D2D pair for D2D communication. The technical solution according to the present invention can simultaneously ensure the communication quality of the cellular user equipment and the communication quality of the D2D pair.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, device and system for determining communication resources of a D2D pair. Background technique [0002] Since the D2D (Device-to-Device, device-to-device) technology can effectively increase the spectral efficiency of the system and reduce the power consumption of the user equipment in the D2D pair (Device-to-Device Pair), it has received more and more attention. s concern. In a network supporting D2D technology, radio resources can be used by cellular UEs and D2D pairs at the same time, so that system resources can be reused compactly. However, the uplink has not been fully utilized compared to the downlink, so most studies on D2D transmission mainly focus on how to enable D2D pairs to reuse the uplink spectrum of the LTE system. [0003] In the mode of sharing uplink resources, especially when the D2D pair is relatively close to the base station,...
