BASE STATION, COMMUNICATION CONTROL METHOD, AND PROCESSOR

摘要

eNB 200-2 receives beamforming control information fed back from each of a plurality of UEs 100-2 that are connected with the eNB 200-2, and null-steering control information fed back from UE 100-1. The eNB 200-2 calculates, for each of the plurality of UEs 100-2, assignment priority by which to assign the same radio resource as a radio resource assigned to the UE 100-1, on the basis of reference priority derived from a scheduling algorithm, and matching degree between the null-steering control information and the beamforming control information. The eNB 200-2 assigns the same radio resource to a UE 100-2 having the highest assignment priority, from among the plurality of UEs 100-2.

主权项

1. A base station managing a cell in a mobile communication system supporting downlink multi-antenna transmission, comprising:
a receiver configured to receive beamforming control information fed back from each of a plurality of terminals that are subject to beamforming and that are connected with the cell, and null-steering control information fed back from a terminal subject to null steering; and a controller configured to calculate, for each of the plurality of terminals subject to beamforming, assignment priority for assigning the same radio resource as a radio resource assigned to the terminal subject to null steering, on the basis of reference priority derived from a scheduling algorithm, and matching degree between the null-steering control information and the beamforming control information, wherein the controller assigns the same radio resource to a terminal subject to beamforming having the highest assignment priority, from among the plurality of terminals subject to beamforming.
