| 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.
