Patent ID: 8649313

Claim:
A mobile station (MS) for use in a wireless network, the wireless network comprising a base station (BS), the MS attempting to request a bandwidth from the BS, the MS comprising: a storage configured to store transmission information and a sequence generating function; a microprocessor electrically connected to the storage and configured to: select a selected transmission sequence from a plurality of transmission sequences according to the sequence generating function; generate a quick access message according to the transmission information, the quick access message at least comprising a station identification (ID) corresponding to the MS; and embed pre-defined bit information into the selected transmission sequence according to the transmission information; and a transceiver electrically connected to the microprocessor and configured to transmit the selected transmission sequence and the quick access message to the BS in a frame so that the BS may allocate the bandwidth to the MS according to the pre-defined bit information and the station ID; wherein, the sequence generating function is: RN= ( a× current_state+ p )mod m wherein RN is a serial number of the selected transmission sequence; a is a first predetermined parameter; current_state is information shared by the BS and the MS, wherein current state includes at least one of the station ID of the MS, a serial number of the frame, a flow ID of the MS, or a combination thereof; p is a second predetermined parameter; and m is a total number of the plurality of transmission sequences.
