摘要： In certain aspects, a method implemented in a wireless device includes determining a specific absorption rate (SAR) distribution for a first wireless communication technology, determining a power density (PD) distribution for a second wireless communication technology, and combining the SAR distribution and the PD distribution to generate a combined RF exposure distribution. The method also includes determining at least one first maximum allowable power level and at least one second maximum allowable power level for a future time slot based on the combined RF exposure distribution, setting at least one transmission power limit for a first transmitter in the future time slot based on the at least one first maximum allowable power level, and setting at least one transmission power limit for a second transmitter in the future time slot based on the at least one second maximum allowable power level.

摘要： Embodiments disclosed herein provide a method and apparatus for optimizing time-averaged transmitter power of a communications device. A time-averaged SAR is computed over a predefined time window using past transmitter power levels with minimum transmitter power equal to reserve transmitter power for any time interval. Based on the time-averaged SAR a maximum allowable transmitter power for a future fixed time interval is determined. The communication device then transmits at a power equal to or less than the maximum allowable transmitter power. The communication device may back off from high transmitter power to a reserve transmitter power when calculated time-averaged SAR approaches the SAR limit. When old high power transmissions expire, the communication device gains SAR margin and may then transmit at high power. The apparatus comprises: at least one antenna, a transmitter in communication with a power supply, a receiver, a timer in communication with a processor, and a memory.
摘要翻译：本文公开的实施例提供了一种用于优化通信设备的时间平均发射机功率的方法和装置。使用过去的发射机功率电平在预定义的时间窗口上计算时间平均SAR，其中最小发射机功率等于在任何时间间隔内保留发射机功率。基于时间平均SAR，确定未来固定时间间隔的最大允许发射机功率。通信装置然后以等于或小于最大允许发射机功率的功率发射。当计算的时间平均SAR接近SAR限制时，通信设备可以从高发射机功率退回到预留发射机功率。当旧的高功率传输过期时，通信设备增加SAR裕度，然后可以以高功率传输。该装置包括：至少一个天线，与电源通信的发射机，接收机，与处理器通信的定时器和存储器。

摘要： Certain aspects of the present disclosure propose methods for determining power level of one or more transmitters based on a power level of a primary transmitter (302) when the transmitters are located in close proximity of each other. The power levels may be determined such that a combined power of all the transmitters is compliant with regulatory radio frequency (RF) safety requirements. For certain aspects, power level of the lower priority transmitters (306) may be determined utilizing one or more look-up tables. For another aspect, power level of the lower priority transmitters may be calculated using an algorithm based on the power level of the priority transmitter. In aspects, the power level of lower priority transmitters and the time duration for which the transmitters are active may be selected dynamically so that the time averaged power of the transmitters for a defined period of time falls below the RF exposure limit.
