Abstract:
1. A method for transmitting data from a portable communication device to a base station via a radio frequency signal, wherein data are transmitted using a plurality of modulation and coding schemes and using a protocol that has recurring frames, each frame having a plurality of transmission slots different numbers of which can be used to transmit the data, the method comprising: deriving a given power level, a given number of transmission slots, and a given modulation and coding scheme from information from the portable communication device; determining whether the given number of transmission slots can be increased; in response to determining the given number of transmissions slots can be increased, increasing the given number of transmission slots provided that a transmission with an increased number of transmission slots will not result in a predefined specific absorption rate limit being exceeded, and transmitting the data at the given power level using the given modulation and coding scheme and an increased number of transmission slots; when the given number of transmission slots cannot be increased: selecting another one of the plurality of modulation and coding schemes as a selected scheme; selecting a certain power level in response to the selected scheme; in response to the certain power level, selecting a certain number of transmission slots so that a data transmission does not result in a specific absorption rate that is greater than the predefined specific absorption rate limit; and transmitting the data at the certain power level using the selected scheme and the certain number of transmission slots.
