摘要： The present invention provides a novel adaptive power configuration method and corresponding base stations in a Het Net. According to the present invention, some specific subframes of a serving base station are scheduled to serve victim UEs, while the corresponding subframes of an aggressor base station can be scheduled to serve its UEs with adaptively adjusting the transmit power instead of thoroughly muting. This adaptive power configuration scheme can efficiently reduce the interference in Het Nets to guarantee the workability of victim UEs, meanwhile more capacity performance gain can be achieved with backward compatibility to legacy UEs.

摘要： A relay method and device, wherein the control signal and the data signal which are in the same subframe are directly sent to a lower level device respectively by an upper level device and a relay function device. In one example, the relay function device transmits data signal using subscriber special reference signal to make the lower level device estimate an access channel correctly; in another example, the relay function device carries out precoding of the data signal correlative with the access channel so as to cancel the influence of the access channel, thereby make the lower level device receive data signal correctly. Retransmission control signaling is sent to the lower level device in each subframe by the upper level device to ensure the fixed sequential relationship of feedback retransmission.

摘要： One embodiment of the invention provides a mechanism to assist the eNodeB of the second cell, for example macrocell eNodeB or femtocell eNodeB to determine the configuration of ABSs. To be specific, the eNodeB of the first cell sends a request signaling to the eNodeB of the second cell to inform of the requirement for ABSs. The eNodeB of the second cell receives the request signaling from the eNodeB of the first cell, and then it determines the pattern of ABSs and sends the pattern of ABSs in the form of bitmap through a signaling to the eNodeB of the first cell. As the requirement for ABSs is determined by the eNodeB of the first cell on the basis of the number of the UEs and/or the traffic load of the UEs which are near the edge of coverage area of the picocell, it can help the eNodeB of the second cell to determine the configuration of ABSs, i.e. the pattern of ABSs, so that the efficient resource utilization is achieved.

摘要翻译： 本发明的一个实施例提供了一种辅助第二小区的eNodeB（例如，宏小区eNodeB或毫微微小区eNodeB）来确定ABS的配置的机制。 具体而言，第一小区的eNodeB向第二小区的eNodeB发送请求信令，以通知ABS的需求。 第二小区的eNodeB接收来自第一小区的eNodeB的请求信令，然后确定ABS的模式，并通过信令将位图形式的ABS模式发送给第一小区的eNodeB。 由于根据UE的数量和/或接近微微小区的覆盖区域的边缘的UE的业务负载，由第一小区的eNodeB确定ABS的要求，所以可以帮助eNodeB 确定ABS的配置的第二个单元，即ABS的模式，从而实现有效的资源利用。
