Disclosed are a method, a device and an eNodeB for implementing CoMP. The method comprises: acquiring the Reference Signal Received Power (RSRP) differential between a serving cell of a determined user equipment and a neighboring cell; designating a user equipment having a differential less than a preset threshold as a candidate cell-edge user equipment, and designating a user equipment having a differential not less than the preset threshold as a cell-center user equipment; designating a user equipment, among the candidate cell-edge user equipments, that meets a preset condition as a cell-center user equipment, so that frequency selection and scheduling thereof are performed in a central band; and performing CoMP on the cell-center user equipments. In the method for implementing CoMP disclosed in the embodiment of the present invention, some cell-edge user equipments are designated as cell-center user equipments and are scheduled on a wider band according to an ICIC scheduling criterion so as to obtain a certain scheduling gain. The interference introduced by said cell-center user equipments may be suppressed by means of CoMP technology, so as to obtain CoMP interference suppression gain. Therefore, the integration between ICIC and CoMP is further enhanced.
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...
