Abstract:
1. A method for allocating subchannels in a wireless network wherein a plurality of users are subscribed in the wireless network, a base station has N T transmission antennas, a user i has N R reception antennas, a network capacity determined by the N T transmission antennas and K subcarrier groups is divided into K transmission subchannel groups, and a network bandwidth determined by the N T transmission antennas is divided into the K subchannel groups; wherein the base station sequentially allocates channels to the plurality of 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, wherein a desired service quality of said each user is a minimum allowable data transmission rate of the user; the method comprising: a step (a) of calculating a relative weight between the users by said base station on the basis of a minimum allowable data transmission rate φ a step (b) of calculating φ a step (c) of selecting the user i having a maximum value of φ a step (d) of executing said steps (a) to (c) for all channels by the base station.
