Patent ID: 8243662

Claim:
A method for implementing bandwidth allocation based on a relay station (RS), in a Bandwidth Wireless Access (BWA) system, comprising: receiving, by a base station (BS) a bandwidth request message from a subscriber station/mobile subscriber station (SS/MSS) relayed by the RS; performing, by the BS, bandwidth allocation for the link of the RS, and generating a bandwidth grant information which reflects the corresponding bandwidth allocation, wherein the bandwidth grant information comprises a UL-MAP RS message which is adapted to bandwidth allocation for the uplink of the RS and a DL-MAP RS message which is adapted to bandwidth allocation for the downlink of the RS, and usage and location of each burst of corresponding connection of the SS/MSS belonging to the RS is indicated in the DL-MAP RS message and the UL-MAP RS message; sending, by the BS, the bandwidth grant information to the RS; and performing, by the RS, a relay processing to the UL-MAP RS message and the DL-MAP RS message and transmitting the UL-MAP RS message and the DL-MAP RS message to the SS/MSS or a subordinate RS.
