Abstract

The embodiment of the invention discloses a relay communication method and device, relates to the field of communication, and solves the problem of how to perform uplink communication between remote equipment and target wireless access network equipment through relay equipment when the remote equipment moves to a coverage range of a target cell in a one-way relay scene. According to the specific scheme, the method comprises the following steps that: after first wireless access network equipment receives first information sent by first terminal equipment, a second terminal device for providinga relay service for a first terminal device in a target cell can be determined according to first information, wherein the first information is used for indicating that the first terminal device is aterminal device with limited uplink power, the first wireless access network equipment sends second information to second wireless access network equipment, and the second information is used for indicating the second terminal device which provides relay service for the first terminal device in the target cell.

Description

technical field [0001] The embodiments of the present application relate to the communication field, and in particular, to a relay communication method and device. Background technique [0002] In the fifth generation (5G) mobile communication technology, for a remote device with limited power, the remote device can communicate with the wireless access network device through a relay device, thereby reducing the power of the remote device. power consumption, the relay device here may be a terminal device, and a side link (sidelink) exists between them. The 3rd generation partnership project 3GPP topic discusses two-way relaying and one-way relaying. The so-called two-way relay means that both the uplink data and the downlink data between the remote device and the radio access network device are forwarded through the relay device. One-way relay means that the uplink data between the remote device and the wireless access network device is forwarded through the relay device, a...
