Abstract:
1. A method for using frequency and time resources by a Base Station (BS) in a communication system comprising at least two frequency subbands and a guard interval between the at least two frequency subbands, the method comprising: setting part of a guard interval between a first frequency subband and a second frequency subband among the at least two frequency subbands as at least one of a transmission frequency band and a reception frequency band, according to whether the first frequency subband and the second frequency subband are used as the transmission frequency band or the reception frequency band; and communicating with a Mobile Station (MS) in at least one set frequency band, wherein the part of the guard interval is used as the transmission frequency band when the first frequency subband and the second frequency subband are used as the transmission frequency band, wherein the part of the guard interval is used as the reception frequency band when the first frequency subband and the second frequency subband are used as the reception frequency band, and wherein the at least one set frequency band has a time duration equal to a shorter time duration of the first frequency subband and the second frequency subband.
