Adaptive radio downlink output power compensation based on temperature and traffic load

Abstract

The technology described herein is directed towards determining (e.g., a base station's) radio downlink power output based on traffic load data and temperature data. The downlink power output can be a compensation value that modifies the radio's power output by adapting to dynamic traffic load and temperature changes. Using traffic load and temperature results in more accurate power compensation. In one implementation, the current (most-recent) traffic load data and temperature data are used to obtain bounding values from a table indexed by traffic load data intervals and temperature data intervals. The bounding values are interpolated to find a power compensation value. By considering the downlink traffic, good correlation is maintained between the radio internal temperature reading and the actual radio ambient temperature, resulting in a more accurate power compensation value for any combination of downlink traffic load and internal temperature reading. This results in improved serving cell coverage.
