Abstract
A station includes a reservation request transmitter, a bandwidth request transmitter, and a data transmitter. The reservation request transmitter transmits a reservation request to an access point during a contention slot specified by the access point. The contention slot is periodically allocated by the access point. The bandwidth request transmitter transmits a bandwidth request to the access point using a first allocated bandwidth allocated to the station as a response to the reservation request. The bandwidth request has a first data structure different from a second data structure of the reservation request, and includes information indicating a required bandwidth for transmitting a data to be transmitted. The data transmitter transmits the data using a second allocated bandwidth allocated to the station based on the required bandwidth.
