Abstract

The invention discloses a neighbourhood cooperative multipoint transmission information updating method and a device and system thereof, relating to the field of wireless communication and solving the problem that eNB can not initiatively acquire CoMP information of neighbourhood. The method includes: a base station receives a CoMP update message sent by an adjacent base station, the CoMP update message contains the CoMP information of all the cells of the adjacent base station; and the base station stores the CoMP information or updates related CoMP information stored on the base station according to the CoMP update message. The technical scheme provided by the invention is applicable to universal evolution type terrestrial wireless access network of the third generation mobile communication long term evolution system.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, device and system for updating Coordinated Multiple Point transmission / reception (CoMP, Coordinated Multiple Point transmission / reception) information of neighboring cells. Background technique [0002] In the evolved universal terrestrial radio access network of the third-generation mobile communication long-term evolution system, the uplink and downlink data between the user equipment (UE) and the base station are transmitted through the uplink shared channel and the downlink shared channel respectively, and are transmitted by the base station Allocate resources to each UE. E-UTRAN adopts Orthogonal Frequency Division Multiplexing (OFDM) technology. Compared with the second-generation mobile communication system, the radio resource management of E-UTRAN system has the characteristics of large bandwidth and multiple time processes. Its radio resources are ...
