Patent ID: 7535869

Claim:
A method for dynamically assigning resources in a transmitter of an Orthogonal Frequency Division Multiplexing (OFDM) wireless communication system that divides an entire frequency band into a plurality of subcarriers, transmits reference signals through a predetermined number of the plurality of the subcarriers, transmits data signals through subcarriers, not including the subcarriers through which the reference signals are transmitted, and includes a plurality of subchannels, each of which is a set of at least one among the plurality of subcarriers, the method comprising the steps of: receiving channel quality informations (CQIs) including a first parameter related to a mean channel gain of subcarriers in subbands, each of which includes a predetermined number of subcarriers among a plurality of the subcarriers and noise power, and a second parameter related to a variance of subcarriers in the subbands and the noise power, the CQIs being received from respective receivers; and assigning the subchannels, modulation and coding schemes, and a transmission power to the respective receivers based on the first parameter and the second parameter.
