摘要： A simultaneous transmit and receive (STR) technology is described. The eNB is configured with a downlink centric measurement threshold and an uplink centric measurement threshold which increase overall capacity in the wireless cellular network. A signal measurement command is transmitted from the eNB to the UE instructing the UE to take a signal quality measurement. The signal quality measurement is received from the UE at the eNB. It is determined whether the signal quality measurement is greater than the downlink centric measurement threshold and whether the signal quality measurement is greater than the uplink centric measurement threshold. The downlink centric measurement threshold, the uplink centric measurement threshold, and the DL/UL ratio are configured to increase capacity in the wireless cellular network through selective use of STR

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.

摘要： A wireless communication system and method schedules a beginning of an uplink transmission from a wireless device to a network transceiver with a first predetermined period of time after an end of a downlink transmission from the network transceiver device to the wireless device is scheduled. The uplink transmission and the downlink transmission comprise the same carrier frequency. The first predetermined period of time is related to a time required for the wireless device to switch from between receive and transmit modes. A beginning a downlink transmission from the network transceiver to the wireless device is scheduled with a second predetermined period of time after an end of an uplink transmission from the wireless device to the network transceiver is scheduled. The second predetermined period of time is related to a time required for the wireless device to switch between transmit and receive modes.

摘要： Techniques are disclosed that provide for femto base stations to become synchronized with other base stations in a wireless network. For instance, a macro base station may instruct a mobile station to engage in a synchronization operation that synchronizes one or more timings (e.g., OFDM timings) of a femto base station with one or more corresponding timings of the macro base station. This may involve the mobile station having timing references of the macro base station. Further, this may involve the mobile station performing scanning operations and/or handover ranging operations with the femto base station. The mobile device may determine timing offsets between the femto BS and the macro BS. These offsets may be sent to the macro base station or to the femto base station. Also, the femto base station may adopt timings employed by the mobile station. The macro base station or a femto base station may direct a femto base station to achieve synchronization either directly with timing adjustment offset, or with a list of already synchronized femto base station as synchronization reference.
