Abstract
A wireless packet communication system includes at least one radio terminal station, and a base station for multiplexing packets to be transmitted using a plurality of subcarriers and for sending the multiplexed packets to the at least one radio terminal station. The system has a unit provided in the base station for simultaneously sending reference signals on the subcarriers with the same level to the at least one radio terminal station, a report unit provided in the at least one radio terminal station for reporting to the base station received conditions of the reference signal of each subcarrier or of each subband corresponding to a frequency band occupied by a plurality of subcarriers, and a unit provided in the base station for allocating the subcarrier or the subband to each of the packets to be transmitted depending upon the reported received conditions of the subcarrier or the subband, the allocation being performed in a transmission order of the packets.
