摘要： The present invention relates to a wireless self-backhaul technique in a wireless communication network, especially in a WiMAX network, which implements wireless backhaul between base stations by using radio resources (frequency, sub-band or timeslot) of base stations' own. More specifically, uplink and downlink backhaul channels are formed between a master base station and a slaver base station using base stations' inherent resources and through offsetting the frame start time of the slaver base station for a period of time in relation to the master base station. The slaver base station operates in base station mode during local user access and operates in subscriber station mode during implementing wireless backhaul traffic with the master base station. Therefore, the slaver base station needs to switch between these two operating modes.

摘要： To address the drawbacks of the current bandwidth requesting and allocation in the wireless broadband access network, the present invention proposes a technical solution of fast bandwidth requesting and allocation, wherein the MS sends a bandwidth allocation request message to the BS for only once, and the interactions between the BS and the MS are decreased so as to increase the efficiency of bandwidth requesting and allocation, effectively shorten the transmission waiting time of traffic data, and especially improve the support for latency-sensitive data traffic. Due to the fact that the interactions between the BS and the MS are decreased, various processing resources in the BS and the MS are spared. Additionally, the BS can also adjust the size of the time/frequency resource block on which each mobile station sends the bandwidth allocation request message according to the number of the mobile stations covered by the base station, and/or according to the traffic types in each mobile station, so as to make the whole wireless communication system operate efficiently.
