摘要: We propose a novel interference management framework for the cellular downlink through cooperative transmission. A sectored network is studied where only due to sectors in neighboring cells and intra cell ignored. first explore potential degrees of freedom (DoF) gain scenario mobile receivers can be associated any but no transmission allowed. show that maximum achievable per user DoF orthogonal schemes between 1/3 3/7. On other hand, if combined with flexible message assignment transmitters, we it possible achieve 7/15. In addition, proposed scheme does not require extra backhaul capacity, as uses smart messages transmitters meet an average load constraint one transmitter.
