摘要： A method is provided a wireless system for providing small “guard” cells in a heterogeneous network at locations proximate to privately-maintained HeNB (or femto) cells in the heterogeneous network. More particularly, the methodology of the invention addresses the problem of a mobile user in a heterogeneous network located nearby to a privately maintained HeNB cell in the heterogeneous network, and the inherent interference created for the HeNB cell by the necessity of the mobile user having to transmit and receive communications from a distant public macro eNB. By deploying small public “guard” cells in the macro cell proximate to the private HeNB cells, such a public mobile terminal is enabled to communicate with the public small cell at generally lower power than would have been necessary for communication with the distant macro eNB, with a resulting reduction in interference for the nearby HeNB cell. The FL interference between the macro cell and the HeNBs is also mitigated.
摘要翻译：提供了一种无线系统，用于在异构网络中的邻近私有维护HeNB（或毫微微）小区的位置的异构网络中提供小的“保护”小区。更具体地说，本发明的方法解决了位于异构网络中私有维护的HeNB小区附近的异构网络中的移动用户的问题，以及由移动用户必须为HeNB小区创建的固有干扰从远程的公共宏eNB发送和接收通信。通过在靠近私有HeNB小区的宏小区中部署小的公共“保卫”小区，这样的公共移动终端能够以比与远程宏eNB进行通信所需的一般功率更小的功率与公共小小区进行通信，导致附近HeNB电池的干扰减少。宏小区和HeNB之间的FL干扰也得到缓解。

摘要： A multi-stream wireless relay is arranged to maintain independent data streams with multiple base stations and thereby provide a relay from those multiple base stations to mobile units having respective communication relationships with those multiple base stations. In an alternative approach, the data streams from the multiple base stations are superposed on each other, wherein harmful inter-cell interference is converted into useful information bearing signals, thereby enabling the scheduling of transmission resources from the multiple base stations for a single mobile unit via the relay.
