Abstract

The invention discloses a method and a device for supporting coverage extension and business continuity in a relay station used for receiving signaling and data from a remote user and transmitting the signaling and the data from the remote user to a base station. The method comprises any one of the following steps that the relay station is provided with an S1-AP (S1Application Protocol) function and receives an attach request from the remote user, and the relay station sends S1-AP signaling, which is packaged in RRC (Radio Resource Control) signaling, of the remote user to the base station or sends the S1-AP signaling to the base station through a data radio bearer; or the relay station receives the attach request from the remote user and sends NAS (Non Access Stratum) signaling, which is packaged in the RRC signaling, of the attach request of the remote user to the base station; or the relay station receives the RRC signaling from the remote user through a PC5 interface and sends the RRC signaling to the base station through a first data radio bearer. The scheme not only supports coverage extension but also business continuity.

Description

technical field [0001] The present invention relates to a wireless communication network, and more particularly, to a method and a device for supporting coverage extension and service continuity in a wireless communication network. Background technique [0002] The Proximity Service (ProSe: Proximity Service) direct communication is introduced in LTE-A of REL12. A user equipment (UE: User Equipment) supporting ProSe direct communication can operate in two resource configuration modes: 1) scheduled resource allocation (ie mode 1); and 2) UE autonomous resource selection (ie mode 2). If a UE not within the network coverage wants to perform ProSe direct communication, it can only use UE autonomous resource selection; if a UE within network coverage wants to perform ProSe direct communication, it can use scheduled resource allocation or UE autonomous resource selection choose. [0003] In REL13, a relay station (UE-NW RN: ​​UE to Network RelayNode) between the user equipment a...
