Abstract:
1. A method in a first carrier controller, associated with a network node for distributed power management of a plurality of power amplifiers within a sector, the first carrier controller, the network node and the power amplifiers are comprised within a communication system together with at least one further carrier controller, the first carrier controller being arranged for scheduling power allocation at each power amplifier of the radio frequency power estimated to be used by at least one carrier controlled by the first carrier controller, the method comprising: (1) estimating the radio frequency power to be used by the at least one carrier controlled by the first carrier controller during a predetermined time frame on one or more power amplifiers within the same sector; (2) distributing the estimated radio frequency power to the further carrier controller; (3) obtaining the estimated radio frequency power to be used by the at least one carrier controlled by the further carrier controller during the predetermined time frame; (4) based on (1) and (3), performing an allocation of radio frequency power to the one or more power amplifiers with the same sector; (5) if a maximum power threshold is exceeded for any of the one or more power amplifiers, performing a reallocation of the radio frequency power based on priority of the at least one carrier.
