Abstract: Methods and apparatus are proposed for computing a power reduction policy to control radio emissions of a base station over a time window, with the objective to keep the time-averaged radio emissions over the time window below an authorized value set by regulations, with minimum impact on the performance of the overall system. The time window is subdivided into a plurality of time periods starting at a plurality of time steps, and the policy control comprises, at least at a first time step in the time window: generating a predicted average radio emissions over subsequent time periods in the time window, based on radio emissions historical data; finding couples of values of a power reduction factor and an average radio emissions that minimize a cost function for each time step in the time window, based on the predicted average radio emissions.

Abstract: An apparatus comprising circuitry configured to: determine at least one parameter used to determine an energy cap for a time period for at least one network node within a cluster of at least one network node comprising the at least one network node; determine the energy cap for the time period for the at least one network node within the cluster, based on the at least one parameter; wherein the energy cap for the time period for the at least one network node is determined so that energy consumed by the cluster during a time window comprising multiple time periods does not exceed an energy constraint, the multiple time periods comprising the time period; and transmit the energy cap for the time period to the at least one network node within the cluster at a beginning of the time period.

Abstract: The present subject matter relates to a method for controlling radio frequency, RF, emissions, including maintaining a number of power units below a maximum number within a time interval, wherein a power unit of the power units is indicative of an amount of radiated power for transmission of data. A data element to be transmitted may be received during the time interval. A number of the power units representing an amount of radiated power for the transmission of the data element may be determined. The data element may be transmitted depending on the current maintained number of power units and the determined number. The current maintained number of power units may be decreased by the determined number of power units if the data element is transmitted.
