Power-efficient body proximity sensing for mmWave systems

A method for a user equipment (UE) to perform operations via processing circuitry, comprising:

• generating new radio (NR) communications in millimeter wave (mmW) frequency on one or more bands;
• performing body proximity sensing (BPS) operations on the one or more bands;
• generating a determination of whether a maximum permissible exposure (MPE) event in the one or more bands is triggered based on the BPS operations;
• in response to the determination, determining a safe transmit power level associated with the one or more bands to provide the NR communications;
• and
• determining whether one or more conditions are satisfied to suspend the BPS operations temporarily.

A base station comprising:

• a memory;
• and
• processing circuitry configured to:
• process new radio (NR) communications in millimeter wave (mmW) frequency on one or more bands;
• and
• process a data set of safe transmit power levels associated with different bands to enable a determination of whether a maximum permissible exposure (MPE) event in the one or more bands is triggered based on body proximity sensing (BPS) operations and in response to a transmit power level being less than an entry in the data set or data table suspending the BPS operations.
