Abstract
A method and system for dynamic power control for next generation LTE base stations are described herein. More particularly, a dynamic power control management process may run, for example, in an OA&M module on the control plane core of the base station. The dynamic power control management process collaborates with various components, such as a call management processing module and a transport process module, to periodically obtain information regarding the number of active calls as well as the uplink and downlink data rates for a given interval for a particular cell. The dynamic power control management process polls the call management processing module and transport process module periodically according to a tunable parameter for the key values. Based on this information, the dynamic power control management process determines whether a particular cell on the base station is running below a threshold at which dynamic power control could be triggered.
