Licensed Assisted Access Signal Detection for Reducing Power Use

Abstract:

This disclosure relates to techniques for detecting a signal and powering off at least some receiver components if no signal is detected. A wireless device may take one or more measurements of one or more signals. The wireless device may determine, based on the measurements, whether a signal (e.g., a signal of a licensed assisted access cell) is anticipated during an upcoming time period, e.g., a subframe or portion of a subframe. If no signal is anticipated, the wireless device may power off at least some receiver functions.
