Abstract  Abstract

A base station apparatus in a mobile communications system has a unit which transmits to one or more user apparatuses a downlink control signal including information for allocating a radio resource a unit which receives an uplink signal from the one or more user apparatuses and a unit which determines based on a feedback from the user apparatus a pre-encoding matrix indicator (PMI) indicating a pre-encoding matrix to be applied to multiple antennas of the base station apparatus. When a number of multiplexed users in the downlink control signal is no less than a predetermined number the PMI indicating the pre-encoding matrix to be applied to a whole system bandwidth of the mobile communications system is reported to each of the user apparatuses.
