摘要： Methods and apparatuses are provided for determining a transmission power cap for one or more devices based at least in part on pathloss measurements to one or more access points received from the one or more devices. A common transmission power cap can also be computed for assigning to devices communicating with an access point, and the transmission power cap for a given device can be adjusted when the transmission power is at or a threshold level from the common power cap to conserve signaling in the wireless network. Adjustment of the transmission power cap can additionally or alternatively be based on a received power at an access point related to signals from the device, an interference report from one or more access points, and/or the like.

摘要： Methods and apparatuses are provided for mitigating interference among access points, and/or devices communicating therewith, in unplanned network deployments. Based on determining that one or more served devices potentially interfere with one or more access points, an inter-frequency handover (IFHO) threshold or data rate can be adjusted for the device to cause IFHO or reduce occurrence of interference, and/or a coverage area can be modified so the device can communicate with one or more other access points to mitigate potential interference. Based on determining interference from one or more devices served by other access points, an access point can switch operating modes to a hybrid or open access point to allow the one or more devices to handover to the access point, and/or can boost downlink transmit power to cause the one or more devices to perform IFHO from the other access points to mitigate potential interference.

摘要： Techniques are provided for overcoming uplink (UL) interference at a femtocell or the like by modifying the estimated interference-plus-noise power in UL power control. In one example, the modification can be specified by a method, operable by a network entity, that may involve determining a level of excess received interference based at least in part on out-of-cell interference (Ioc). In another example, the modification can be specified by a method, operable by a network entity, that may involve determining a difference between the downlink transmit powers of the high-speed downlink packet access (HSDPA) serving and non-serving cells, with which the UE are in soft handover (SHO) in uplink and is served by the HSDPA serving cell in downlink.

摘要： Methods and apparatuses are provided for determining whether to handover a device to mitigate uplink interference while achieving acceptable uplink service quality in a wireless network. One or more parameters related to a device can be evaluated to determine whether to handover the device, such as a number of transmission power reports received from the device over a period of time, a frame error rate, setpoint, or power control commands related to the uplink of the device, a received pilot signal strength at the device, an uplink throughput or buffer size at the device, etc., from which transmit power information of the device can be inferred for determining whether the device potentially interferes with access points or devices. Based on the one or more parameters, an access point can determine whether handing over the device may mitigate such uplink interference while ensuring uplink service quality, and accordingly handover the device.
