Abstract
Techniques and apparatus for radio frequency (RF) exposure management for multiple radios are described. An example method of wireless communication by a wireless device generally includes determining a first exposure associated with a first radio for a first transmission in a first time interval; determining a first allowable transmit power associated with a second radio for a second time interval based at least in part on the first exposure associated with the first radio; and transmitting a first signal at a first transmit power in the second time interval using the second radio based on the first allowable transmit power.
Claims29
A method of wireless communication by a wireless device, comprising:
- determining a first exposure associated with a first radio for a first transmission in a first time interval;
- determining a first allowable transmit power associated with a second radio for a second time interval based at least in part on the first exposure associated with the first radio;
- and
- transmitting a first signal at a first transmit power in the second time interval using the second radio based on the first allowable transmit power,
- wherein determining the first allowable transmit power comprises:
- determining a first exposure margin associated with the second radio based on the first exposure associated with the first radio;
- and
- determining the first allowable transmit power based on the first exposure margin and a second maximum time-averaged transmit power level associated with the second radio.
An apparatus for wireless communication, comprising:
- one or more memories collectively storing executable instructions;
- and
- one or more processors coupled to the one or more memories, the one or more processors being collectively configured to execute the executable instructions to cause the apparatus to:
- determine a first exposure associated with a first radio for a first transmission in a first time interval,
- determine a first allowable transmit power associated with a second radio for a second time interval based at least in part on the first exposure associated with the first radio, and
- control transmission of a first signal at a first transmit power in the second time interval using the second radio based on the first allowable transmit power,
- wherein to determine the first allowable transmit power, the one or more processors are collectively configured to execute the executable instructions to cause the apparatus to:
- determine a first exposure margin associated with the second radio based on the first exposure associated with the first radio;
- and
- determine the first allowable transmit power based on the first exposure margin and a second maximum time-averaged transmit power level associated with the second radio.
An apparatus for wireless communication, comprising:
- means for determining a first exposure associated with a first radio for a first transmission in a first time interval;
- means for determining a first exposure margin associated with a second radio based on the first exposure associated with the first radio;
- means for determining a first allowable transmit power associated with the second radio for a second time interval based at least in part on the first exposure margin and a second maximum time-averaged transmit power level associated with the second radio;
- and
- means for transmitting a first signal at a first transmit power in the second time interval using the second radio based on the first allowable transmit power.
A non-transitory computer-readable medium having instructions stored thereon, which when executed by an apparatus, cause the apparatus to perform an operation comprising:
- determining a first exposure associated with a first radio for a first transmission in a first time interval;
- determining a first allowable transmit power associated with a second radio for a second time interval based at least in part on the first exposure associated with the first radio;
- and
- transmitting a first signal at a first transmit power in the second time interval using the second radio based on the first allowable transmit power,
- wherein determining the first allowable transmit power comprises:
- determining a first exposure margin associated with the second radio based on the first exposure associated with the first radio;
- and
- determining the first allowable transmit power based on the first exposure margin and a second maximum time-averaged transmit power level associated with the second radio.
