Abstract

The invention provides a relay transfer method and apparatus, a terminal and a base station. The method comprises the following steps: in the case that remote user equipment UE performs path relay switching from a first relay device to a second relay device, the remote UE executes radio link control RLC reestablishment and packet data convergence protocol PDCP operations. By adoption of the relaytransfer method and apparatus provided by the invention, the problem that service interruption is generated easily when a terminal user moves in related art is solved, and continuous sending and receiving of service in a movement process are achieved, thereby achieving an effect of service continuity and improving the user experience.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a relay transfer method and device, a terminal, and a base station. Background technique [0002] With the development of wireless multimedia services, people's demand for high data rate and user experience and power saving of user equipment is increasing, which puts forward higher requirements for the system capacity and coverage of traditional cellular networks, and thus prompts the development of relay technology. produce. In the relay, data transmission can be performed between the remote user equipment and the base station through a relay station. Among them, the communication technology between the common user equipment and the relay station may include but not limited to D2D (Device-to-Device, device-to-device) technology, wireless fidelity WiFi technology, Bluetooth technology, and the communication technology used in the operator network . Operator network communica...
