Abstract: The present invention discloses a method of requesting resource from a resource allocating apparatus by a request requesting apparatus, a resource allocating apparatus, a resource requesting apparatus and a communication system. The method comprises the following steps: sending a resource request message from the resource requesting apparatus to the resource allocating apparatus; after receiving the resource request message, if resource cannot be allocated within a set time interval with respect to the resource requesting apparatus, sending an acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus; and if the resource is allocated to the resource requesting apparatus within the set time interval, not sending the acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus. Utilizing the method and structure of the present invention, the resource allocating apparatus sends additional acknowledgement message only if needed, therefore overhead is reduced much more. Moreover, since the solution of the present invention does not change any signaling exchanged between the resource allocating apparatus and the resource requesting apparatus, it is able to meet the requirement of backward compatibility.

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.
