Systems and methods for dynamic per-beam adjustment of output power in a wireless network
A system described herein may provide a technique for determining a maximum and/or target output power on a per-beam and/or per-direction basis for a base station of a radio access network (“RAN”) that implements multiple beams for which output power is dynamically adjustable. The maximum and/or target output power for a given beam (or set of beams) for a given time period may be determined based on historical output power information associated with the beam over one or more previous time periods. The maximum and/or target output power may be based on a predicted received signal power within a coverage area of the base station, based on varying levels of output power.
