摘要： In order to solve the drawbacks in the prior art, a new technology scheme is provided in the present invention, in which relay stations are introduced to participate in the communication of multiple carriers. The relay station only relays the carriers with had wireless transmission characteristic and controls the transmission of those relayed carrier via a carrier which does not need to be relayed. The relayed carrier is generally a high frequency carrier and the carrier which does not need to be relayed is a low frequency carrier. The base station or the relay station determines a carrier which needs to be relayed for the relay station according to the channel conditions of each carrier. The technology scheme provided by the present invention divides a NLOS (Non-Line-Of-Sight) transmission into at least two LOS transmissions. Therefore, it is easy to extend high frequency carrier to cell edge etc. Meanwhile the mobile terminal does not need extra transmission power to transmit high frequency carrier, so that the fast consumption of the terminal battery power is avoided and the great radiation hazard to the human body is also avoided. The service data and the signaling etc. which has not been relayed will still propagate in the low frequency carrier, so that the time delay resulted from the relay is avoided.

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.
