Patent ID: 7359398

Claim:
A wireless communication method of performing wireless communication of information using a transmission frame having an asynchronous access region in a contention access period and a channel-time-allocation access region in a contention free period, the method being under management of a control station in a wireless network, said wireless communication method comprising: transmitting information in the asynchronous access region of the contention access period of the transmission frame; determining an amount of information transmittable in the asynchronous access region during said transmission frame; sending a channel time allocation request to the control station according to a result of said step of determining; and transmitting at least a portion of the information using channel time allocated in the channel-time-allocation access region during said transmission frame, wherein said step of transmitting information using channel time further comprises allocating a guaranteed time slot to transmit a remaining information not transmittable in said asynchronous access region of the transmission frame, and wherein said step of allocating is performed without receiving an announcement of completion of channel time allocation communication from an upper-layer application.
