Abstract
Adjusting the power of an uplink transmission based on duty cycle and proximity sensor information is disclosed. The duty cycle represents the ratio of uplink transmission time slots to downlink transmission time slots in a defined period of time. Thus, if during a time period the percentage of uplink transmission is low, then not as much of a power reduction is implemented. If the percentage of uplink transmission is high, then an increased power reduction can be implemented to ensure that the MPE is not exceeded. This duty cycle information can be paired with proximity sensor data to determine whether a person is present. If no person is present, then no power reductions need to be implemented, and if a person is present, then various levels of power reduction can be implemented based on the duty cycle.
