1. A method, comprising:
- sensing, using one or more sensors in a wireless communication device, information related to a state and/or alignment of the wireless communication device;
configuring the wireless communication device based on the information sensed by the one or more sensors;
determining a direction of arrival estimate of a received signal in the wireless communication device, wherein sensed conditions relating to the state and/or alignment of the wireless communication device are utilized to affect the behavior of the wireless communication device while determining the direction of arrival estimate; and
performing power management that disables the direction of arrival estimate determination when one or more sensors detect that the wireless communication device is stationary.

Abstract
A system for enhancing the performance of a wireless communication device (WCD) while executing a direction of arrival (DoA) estimation. The performance may be improved through device management, and may include the collection of information from one or more sensors installed within the WCD. The sensor information may initially be used to determine an appropriate configuration for the device. Further, the sensor information may also be used to affect the behavior of the device while performing the DoA estimation.
