Abstract: A method for improving transmission power management with compliance to regulations of radiofrequency exposure, which may comprise: at a current time, estimating whether a window average power, which may reflect average power transmitted using a radio technology during a moving time window, will exceed a power limit after the current time; if true, proceeding to at least one of a first handling subroutine and a second handling subroutine to set a power cap, and causing power transmitted to be capped by the power cap after the current time. The first handling subroutine may comprise: scheduling to set the power cap lower at a scheduled time. Estimating whether the window average power will exceed the power limit may involve discarding one of a plurality of power records. The second handling subroutine may comprise: setting the power cap not higher than the discarded one of the plurality of power records.

Abstract: A method for dynamically allocating transmitting (TX) powers to multiple TX modules of a radio module includes: for each of the multiple TX modules: mapping a radio frequency (RF) exposure limit to a TX power limit; obtaining a first TX power limit corresponding a first time interval and a second TX power limit corresponding a second time interval, wherein the first time interval is earlier than the second time interval; in response to a TX power corresponding to the first time interval being smaller than the first TX power limit, calculating and storing a value of an unused TX power corresponding the first time interval in at least one power pool within a memory; and in response to a TX power corresponding to the second time interval being larger than the second TX power limit, obtaining the value of the unused TX power from the at least one power pool.
