Title:
BASE STATION, COMMUNICATION CONTROL METHOD, AND PROCESSOR
Document Type and Number:
WIPO Patent Application WO/2014/208555
Kind Code:
A1
Abstract:
An eNB (200-2) receives beam forming control information, which is fed back from each of a plurality of pieces of UE (100-2) connecting to the cell of the eNB (200-2), and null steering control information fed back from UE (100-1). For each of the plurality of pieces of UE (100-2), the eNB (200-2) calculates, on the basis of both a reference priority level derived by use of a scheduling algorithm and the degree of correspondence between the null steering control information and the beam forming control information, an allocation priority level of allocating the same radio resource as the radio resource allocated to the UE (100-1). The eNB (200-2) allocates the aforementioned same radio resource to one of the plurality of pieces of UE (100-2) for which the allocation priority level is the highest.
