Abstract: A method for adjusting a transmitting (TX) power ratio of a radio module includes: separating multiple radio modules into multiple radio groups according to a radiofrequency (RF) regulation, wherein the multiple radio modules comprise the radio module; mapping an RF exposure limit to a TX power limit; interacting with at least one other radio module for adjusting the TX power ratio, to obtain at least one adjusted TX power ratio, wherein the radio module and the at least one other radio module are comprised in a same radio group of the multiple radio groups; and adjusting the TX power limit according to the at least one adjusted TX power ratio, to generate an adjusted TX power limit of the radio module.

Abstract: A method for adjusting time-averaged (TA) parameters of a transmitting (TX) power of a radio module includes: obtaining at least one message of the at least one other radio module or at least one message of the radio module; determining a scenario of the TX power of the radio module according to the at least one message of the at least one other radio module or the at least one message of the radio module; determining whether the scenario is different from a predetermined scenario of the TX power of the radio module; and in response to the scenario being different from the predetermined scenario, adjusting the TA parameters according to the scenario.

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.
