1. A method for improving transmission power management with compliance to regulations of radiofrequency exposure, comprising a first-radio type-one control procedure; the first-radio type-one control procedure being executed by a user equipment, and comprising:
at a current time, estimating whether a first-radio window average power, which reflects average power transmitted using a first radio technology during a moving time window, will exceed a first-radio power limit after the current time; and
if it is estimated that the first-radio window average power will exceed the first-radio power limit after the current time, proceeding to at least one of a first handling subroutine and a second handling subroutine to set a first-radio power cap;
wherein the method further comprises: causing power transmitted using the first radio technology to be capped by the first-radio power cap; and
wherein estimating whether the first-radio window average power will exceed the first-radio power limit after the current time comprises:
by assuming that the first-radio power cap is lowered at a hypothetical back-off time, calculating the first-radio window average power of a future time, wherein the hypothetical back-off time is not earlier than the current time, and the future time is later than the hypothetical back-off time;
wherein the first handling subroutine comprises: scheduling to set the first-radio power cap lower at a scheduled time earlier than the hypothetical back-off time;
wherein estimating whether the first-radio window average power will exceed the first-radio power limit after the current time involves discarding one of a plurality of power records; and
wherein the second handling subroutine comprises: setting the first-radio power cap not higher than the discarded one of the plurality of power records.
