Abstract
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.
