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： 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.
摘要翻译：为了解决现有技术的缺点，在本发明中提供了一种新的技术方案，其中引入了中继站以参与多个载波的通信。中继站仅中继具有无线传输特性的载波，并通过不需要中继的载波来控制那些中继载波的传输。中继载波通常是高频载波，不需要中继的载波是低频载波。基站或中继站根据每个载波的信道状况确定需要为中继站中继的载波。本发明提供的技术方案将NLOS（非视线）传输划分为至少两个LOS传输。因此，容易将高频载波扩展到小区边缘等。同时，移动终端不需要额外的传输功率来传输高频载波，从而避免了终端电池电力的快速消耗，并且对于人体也避免了。尚未中继的业务数据和信令等仍将在低频载波中传播，从而避免了继电器产生的时延。
