    摘要: A method is disclosed to eliminate inter-cluster interference of user equipment located at the edge of a cluster of cells. The method operates by employing fractional frequency reuse (FFR) principles on clusters or combinations of cells in a wireless neighborhood, in which base stations in the cells coordinate their operations in a scheme known as coordinated multi-point transmission (CoMP). By using the FFR principles to single out edge users of the CoMP cluster, the method mitigates interference and increases throughput for the edge users.

    摘要: Wireless-device-to-wireless device (WD-WD) interference in a full-duplex wireless network is managed by an uplink transmit power control technique that minimizes interference experienced in downlink signals at other wireless devices in the wireless network. In one exemplary embodiment, an instantaneous antenna gain of the wireless device and a target uplink Signal-to-Interference-plus-Noise Ratio (SINR) of an uplink signal of the wireless device to the home base station are determined at the wireless device. A Noise plus Interference level at the home base station is received by either a closed-loop or an open-loop feedback technique. The uplink power level for an uplink signal of the wireless device is determined based on the determined antenna gain, the determined target uplink SINR and the received Noise plus Interference level at the home base station.
