BASE STATION DEVICE, USER DEVICE, AND METHOD IN MOBILE COMMUNICATION SYSTEM

摘要

A base station apparatus includes: a scheduling unit configured to determine resources to be assigned to one or more users requesting downlink communication; a unit configured to determine a PV applied to a plurality of antennas according to a feedback signal from each user apparatus; a communication scheme determination unit configured to determine for each user whether to perform feedback control of PV every predetermined number of resource blocks (RB) according to a downlink data amount requested by each user; and a unit configured to transmit a downlink signal from the plurality of antennas using resources determined by the scheduling unit. When the feedback control of PV is performed commonly for RBs in the system band, the communication scheme determination unit also determines whether to use delay diversity for downlink communication.
