Abstract:
1. A wireless communication method in which a plurality of terminal stations are connected with a base station by a common wireless line, the base station managing a bandwidth for bandwidth assignment in an uplink communication bandwidth of a wireless frame as a demand assignment period and a remaining bandwidth as a random access period, and assigning a requested uplink communication bandwidth to the demand assignment period according to bandwidth request information from a terminal station among the plurality of the terminal stations, and the terminal station transmitting, by random access, the bandwidth request information in the random access period after a back-off time lapses when data to transmit is generated, and transmitting the data to transmit using a bandwidth assigned from the base station when the transmission is successfully performed, the wireless communication method comprising: identifying, by the base station, first data of a data exchange sequence from a data type in the data; specifying, by the base station, a predetermined sequence from known data exchange sequence group; setting, by the base station, a first reception timing of the first data for the predetermined sequence as an initiation of a specific period in which a frequency of data transmission is high, the specific period being specified for each terminal station or each wireless link between the terminal station and the base station; setting, by the base station, a second reception timing of last data as a termination of the specific period; performing, by the base station, bandwidth assignment for each terminal station or each wireless link even when the base station does not receive a bandwidth request in the random access from the terminal station in the demand assignment period present in the specific period; and transmitting, by the terminal station, the bandwidth request information or the data to transmit in the bandwidth assigned by the base station.
