BROADBAND POWER MANAGEMENT (POWER BANKING) WITHIN A BROADBAND MULTI-CARRIER BASE STATION TRANSCEIVER SYSTEM

摘要

A method and apparatus to manage RF power in a broadband transceiver station (BTS) that includes a multi-carrier common RF power source such as a multi-carrier power amplifier (MCPA), for maintaining carrier power at a prescribed level. The power is managed by a power banking agent which is a module of the BTS system software. On a new channel request, the power banking agent determines if the request can be satisfied at the requested level. Otherwise, the power banking agent determines if the channel request can be satisfied at a lower power level. The power banking agent also manages active channels by reclaiming power from channels requiring less power and/or by allocating more power to the channels requiring more power. If the power banking agent cannot satisfy a request, the power banking agent will queue the request until a later time in the event that additional power becomes available. The power banking agent also processes alarms which can occur in the event of a MCPA module addition or MCPA module failure.
