Abstract
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.
