Abstract

The invention relates to the technical field of wireless communication, in particular to a communication method, device and system. The embodiment of the invention provides a communication method, which comprises the following steps that first communication equipment schedules second communication equipment in different subsets in N second communication equipment to send signals in each channel measurement time period of T channel measurement time periods, and the subsets need to meet a certain rule. The method aims at utilizing time-frequency domain resources as few as possible to complete link measurement between the D2D communication terminals, and link measurement between the D2D communication terminals can be realized by applying the technical scheme provided by the embodiment of theinvention under various scenes of time-frequency domain resource quantity change or terminal quantity change participating in D2D communication.

Description

Technical field [0001] This application relates to the field of wireless communication technology, and in particular to a communication method, device and system. Background technique [0002] With the development of wireless communication technology and the popularization of smart terminals, the number of terminals in wireless networks has increased dramatically. The end-to-end (Device to Device, D2D) communication technology realizes communication between short-distance terminals, so that it can share the network load of the wireless network and support more types of communication services. At the same time, based on the natural advantages of short-distance communication, D2D communication technology can also improve spectrum efficiency, obtain higher throughput performance and lower transmission delay. [0003] In the prior art, data transmission is usually carried out by broadcasting between terminals performing D2D communication, and there is no link adaptation function betwe...
