Method and apparatus for device transmit power capping in wireless communications

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.

主权项

1. A method for determining a transmission power cap for a device to mitigate interference at least at an access point, comprising:
receiving a pathloss measurement to at least one access point from a device; computing a transmission power cap for a plurality of devices based at least in part on the pathloss measurement, wherein the transmission power cap is common for the plurality of devices; causing the plurality of devices to communicate according to the transmission power cap; and adjusting the transmission power cap for an individual device of the plurality of devices based at least in part on determining a device transmission power is at or a threshold level from the transmission power cap, or on determining a received power of one or more signals from the individual device is at or exceeds a received power threshold.
