Abstract

The embodiment of the invention discloses a wireless communication link establishment method and device, a terminal and relay equipment. The method comprises the steps that a first terminal sends a first relay request message to first relay equipment; the first terminal receives a relay response message to the first relay request message from second relay equipment, the second relay equipment comprises at least one relay equipment in the first relay equipment, and the at least one relay equipment is the relay equipment receiving a second relay request message from the second terminal; the first terminal determines a target relay device from the second relay devices according to the relay response message; and the first terminal establishes a first wireless communication link between the first terminal and the second terminal through the target relay device. Therefore, according to the embodiment of the application, the relay request process is bidirectionally initiated by both terminals, and the second relay device participates in the establishment process of the communication link, so that the number of relay devices is reduced, relay resources are saved, and the communication efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method and device for establishing a wireless communication link, a terminal and a relay device. Background technique [0002] The Service and System Aspects (SA) group of the 3rd Generation Partnership Project (3GPP) started Proximity-based Services (ProSe) communication in the protocol Release 12 (Release12) phase related research. [0003] At present, in the Release17 stage, further research on ProSe communication is being carried out. Among them, the two main research points of ProSe communication include supporting user equipment to user equipment relay (UE-to-UE relay) and supporting direct path switching between Uu and PC5 interfaces. However, in the research on supporting UE-to-UE relay, the selection of UE-to-UE relay needs to be considered in detail. In addition, in the process of establishing a wireless communication link, a large numb...
