Abstract

The invention discloses a method and device for relay transmission and relay terminal equipment, which can reduce the processing complexity of relay transmission. The method includes: a relay terminal device sends a bearer establishment request to a core network device, where the bearer establishment request is used to request to establish an EPS bearer of a remote terminal device; the relay terminal device receives a reconfiguration message sent by the access network device, the The reconfiguration message carries the configuration information of the EPS bearer established for the remote terminal device, wherein the EPS bearer includes the cellular data transmission channel between the access network device and the relay terminal device and the relay terminal device and the relay terminal device. D2D data transmission channel between remote terminal devices.

Description

technical field [0001] Embodiments of the present invention relate to the communication field, and more specifically, to a method and device for relay transmission and a relay terminal device. Background technique [0002] Device-to-Device (D2D) technology means that adjacent terminal devices can transmit data through direct links within a short distance without forwarding through access network devices. D2D communication can share licensed frequency band resources with the cellular system to form a unified hybrid cellular-D2D network. In this hybrid network, some terminal devices can still work in cellular communication mode, that is, communicate with other terminal devices through access network devices, while some terminal devices can work in D2D communication, that is, through direct links with other terminal devices Direct transmission of data between roads and other terminal equipment. [0003] In addition, the data transmission between the access network device and ...
