Abstract
A computer-implemented method, system, and computer-readable storage media for scheduling physical resource blocks are provided. Base stations, of a communication radio access network, may be configured with schedulers that assign one or more physical resource blocks to a communication channel of a wireless device based on distance or power. The physical resource blocks allow the wireless device to communicate with the base station. Some resource blocks may be monitored across multiple sites to determine whether an aggregate power for the resource blocks exceeds a threshold. When the aggregate power threshold is surpassed, the schedulers may limit or prevent use of the identified resource blocks.
