CoMP realizing method and device and base station

Abstract

The invention discloses a coordinated multi-point realizing method, a coordinated multi-point realizing device and a base station. The method comprises: acquiring the reference signal receiving power (RSRP) difference between the current service cells and neighbor cells of users subjected to judgment; determining users of which the differences are smaller than a threshold as candidate edge users and users of which the differences are more than or equal to the threshold as central users; determining the users meeting preset conditions among the candidate edge users as central users so that theusers can perform frequency selection scheduling in a central frequency band; and performing CoMP on the central users. In the CoMP realizing method disclosed by the embodiment of the invention, someedge users are determined as the central users, and according to inter-cell interference coordination (ICIC) scheduling standards, and these central users can be scheduled on a wider frequency band to obtain a certain scheduling gain; and the interference introduced by these central users can be inhibited by a CoMP technique to obtain a CoMP interference inhibition gain. Therefore, the performance of the ICIC combined CoMP can be further improved.

Description

technical field [0001] The present invention relates to the field of communications, and in particular to a method, device and base station for realizing CoMP. Background technique [0002] CoMP (coordinated multi-point) is a coordinated multi-point technology, including downlink CoMP transmission and uplink CoMP reception. Uplink CoMP reception improves user throughput through joint reception of user data by multiple cells, and uses joint processing to obtain transmission gain. CoMP includes intra-eNodeB within a base station and inter-eNodeB CoMP between base stations. Intra-eNodeB CoMP cooperation takes place in a base station, and is cooperation between different cells in the same base station. Inter-eNodeB CoMP cooperation occurs between different base stations, and is cooperation between different cells of different base stations. [0003] ICIC (Inter-Cell Interference Coordination) is an inter-cell interference coordination technology, which tries to avoid using th...
