Abstract: A method for performing mapping between one or more radio modules and one or more radiofrequency (RF) groups includes: separating the one or more radio modules into the one or more RF groups according to one or more messages, wherein the one or more messages comprise a previous TX power ratio, a TX power ratio margin, one or more weighting information, one or more TX performance indices, one or more receiving (RX) performance indices, one or more configurations, or one or more usage scenarios; accumulating RF exposure of the one or more radio modules to at least one RF group among the one or more RF groups; and determining at least one transmitting (TX) power limit corresponding to the at least one RF group according to accumulated RF exposure of the at least one RF group.

Abstract: A method for dynamically allocating radio frequency (RF) exposure across multiple RF groups including a first RF group and a second RF group includes: estimating RF exposure of the first RF group according to at least one message of the first RF group, in order to generate estimated RF exposure; calculating RF exposure of the second RF group according to at least one message of the second RF group, the estimated RF exposure, and one or more equations, in order to generate calculated RF exposure, wherein the one or more equations are associated with a predetermined regulation; and determining a TX power limit corresponding to the first RF group and a TX power limit corresponding to the second RF group according to the estimated RF exposure and the calculated RF exposure, respectively.

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.
