Abstract
A subchannel scheduling method in a multi-user MIMO-OFDM environment modifies proportional fairness scheduling specifications and maximizes a system throughput under conditions that a minimum data transmission rate required by a multimedia user be ensured. In a method for allocating subchannels in a wireless network, plural users are subscribed in the wireless network, a base station has Ntransmission antennas, a user i has Nreception antennas, a network capacity determined by the Ntransmission antennas and K subcarrier groups is divided into K transmission subchannel groups, and a network bandwidth determined by the Ntransmission antennas is divided into the K subchannel groups. The base station sequentially allocates channels to the users on the basis of a proportional value of a data transmission rate supported to each user and an average throughput of each user in a predetermined time and a service quality required by each user.
