USER SELECTION METHOD USING EFFICIENT CHANNEL FEEDBACK IN MULTIPLE ANTENNA SYSTEM AND BASE STATION USING THE SAME

摘要

PURPOSE: A user-selecting method and a base station device using the same in a multiple antenna system are provided to select a user terminal by using a subchannel information which is fed back from a user terminal. CONSTITUTION: A scheduler(12) determines the number of subchannels which each user terminal have to feedback at the next cycle according to a predetermined order. A scheduler informs the number of the subchannel to each user terminal. A scheduler assigns the resources based on the channel quality information of the subchannel fed back from each user terminal. A beamformer(14) beams form the down link packet for an plurality of users allocated by the scheduler. A plurality of antennae(11) transmits the signal which is beam formed with the beamformer.
