Abstract
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.
