First Claim
1. A communication method for performing communication using one or more subchannels between a cell station and a plurality of personal stations, the communication method comprising:
- performing communication with a downlink frame for a downlink period in which the cell station communicates with at least one of the plurality of personal stations and an uplink frame for an uplink period in which at least one of the plurality of personal stations communicates with the cell station, in predetermined frame formats, respectively,wherein the frame format of the downlink frame includes a MAP field that notifies, in the downlink period, each personal station of information indicating an available or unavailable subchannel for each personal station, and whereinthe frame format of the uplink frame includes a Refuse MAP (RMAP) field that notifies, in the uplink period, the cell station from a personal station of information distinguishing a subchannel to be used from a suhchannel to be unused by the corressonding personal station among the available subchannels after notifying each personal station of the information.
