Embodiment 1

[0210] This embodiment will be described from the perspective of a base station, and the base station may specifically be an evolved base station (eNB, EvolvedNode B) or other equipment such as a transmitting station.

[0211] A method for controlling a link in cooperative communication, comprising: confirming that a beneficiary terminal and a pre-support terminal have the ability to perform cooperative communication, and sending a first-hop link establishment request to the beneficiary terminal and the pre-support terminal respectively, so that the beneficiary terminal and the pre-support terminal The supporting terminal establishes the physical link of the first hop according to the link establishment request of the first hop; respectively receives the initial measurement information sent by the pre-supporting terminal and / or the beneficiary terminal after initial measurement of the physical link of the first hop, When there is one beneficiary terminal and at least one pre-su...

Embodiment 2

[0300] This embodiment will be described from the perspective of a terminal. The terminal can be used as a supporting terminal or as a beneficiary terminal. Specifically, the terminal can be a mobile phone, a tablet computer, or a personal computer (PC, Personal Computer). When used as a supporting terminal, It can also be an existing E5 (Equipment5, device) device, such as a wireless access device (CPE, Customer Premise Equipment) that receives WIFI, E5, a portable broadband wireless access device (MIFI, mobile Wi-Fi hotspot) or more Powerful Super E5 (Super E5) and other equipment.

[0301] A method for controlling a link in coordinated communication, comprising: a terminal receiving a first-hop link establishment request sent by a base station; the terminal establishing a first-hop physical link according to the first-hop link establishment request; the terminal based on The physical link of the first hop establishes a support link; the terminal measures the support link to...

Embodiment 3

[0389] In this embodiment, the base station is specifically an evolved base station, terminal A is a beneficiary terminal, and terminal B and terminal C are supporting terminals as an example for illustration.

[0390] Such as Figure 3a As shown, the protocol stack of the evolved base station includes the LTE protocol stack (Protocol Stack), and the terminal (including the beneficiary terminal and the supporting terminal) includes the LTE protocol stack and the WIFI protocol stack. On the control plane, a terminal wireless communication mode control layer (RAMC, Radio Access Mode Control) can be established on the upper layer of the protocol stack of the cellular network, and deployed on the evolved base station and the terminal respectively. For example, the RAMC can be deployed on the terminal's Operating System (OS, Operating System) layer, communication protocol stack or high-level application software, and deployed in the main control module of the evolved base station, ...

Abstract

A method for controlling a link in cooperative communication includes: confirming that a beneficial user equipment and a pre-supportive user equipment have a capability of performing cooperative communication; separately sending a first-hop link setup request to the beneficial user equipment and the pre-supportive user equipment, so that the beneficial user equipment and the pre-supportive user equipment establish first-hop physical links according to the first-hop link setup request; separately receiving initial measurement information that is sent by the pre-supportive user equipment and / or the beneficial user equipment after the pre-supportive user equipment and / or the beneficial user equipment performs initial measurement on the first-hop physical link; according to the initial measurement information, selecting a supportive user equipment of the beneficial user equipment from the pre-supportive user equipment or selecting a beneficial user equipment that is supported by the supportive user equipment; establishing a support link based on the established physical links; separately receiving link measurement information of the support link reported by the beneficial user equipment and the supportive user equipment after the beneficial user equipment and the supportive user equipment perform measurement on the support link; and controlling the support link according to the link measurement information. In addition, another method for controlling a link in cooperative communication and a corresponding apparatus and system are further provided.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a link control method, device and system in cooperative communication. Background technique [0002] With the rapid development of mobile communication technology, mobile communication systems of various standards have appeared, for example, Global System of Mobile Communication (GSM, Global System of Mobile communication) network, General Packet Radio Service (GPRS, General Packet Radio Service) network, wideband code division multiple access (WCDMA, Wideband Code Division Multiple Access) network, time division synchronous code division multiple access (TD-SCDMA, Time Division-Synchronous Code Division Multiple Access) network and global microwave interconnection access (WiMAX, Worldwide Interoperability for Microwave Access) network, etc. These mobile communication systems usually provide data communication services in addition to voice communication services.
