Dynamic control of radio frequency device power mode

Abstract

Methods and apparatus for dynamically controlling a power mode of a wireless device are disclosed. Techniques may include receiving, at the wireless device, a radio frequency (RF) signal from a base station; transmitting an RF signal to the base station responsive to the RF signal from the base station; receiving signal power information from the base station, the signal power information being indicative of signal power capabilities of the base station; and adjusting a power mode of the wireless device to a passive mode or a semi-passive mode based on a signal strength of the RF signal received from the base station, a signal strength of the transmitted RF signal sent to the base station, and the signal power information.
