Abstract

The invention discloses a method and a system of wireless communication. The method of the wireless communication includes that a first user device receives first configuration information, wherein the first configuration information is sent by network nodes, and the first configuration information comprises configuration parameters of reference signals; the first user device responds to the reference signals, wherein the reference signals are sent by the first configuration information; and a second user device detects the reference signals. The method and the system of the wireless communication solve the technical problem that in the prior art, service data can not be directly transmitted between user devices without transmission of a base station. Therefore, the method of the wireless communication has the advantages of saving wireless spectrum resource and reducing data transmission pressure of a core network.

Description

technical field [0001] The present invention relates to the field of communications, and in particular, to a wireless communication method and system. Background technique [0002] Because the cellular communication system realizes the multiplexing of limited spectrum resources, the wireless communication technology has been developed vigorously. In a cellular system, when a service needs to be transmitted between two user equipments (UE1), the service data from user equipment 1 (UE1) to user equipment 2 (UE2) will first be transmitted to the base station through the air interface. 1. Base station 1 transmits the user data to base station 2 through the core network, and base station 2 transmits the above service data to UE2 through the air interface. The service data from UE2 to UE1 is transmitted using a similar processing flow. like figure 1 As shown, when UE1 and UE2 are located in the same cell, although base station 1 and base station 2 are the same site, one data tr...
