Abstract
In one embodiment, a method is performed. A device may receive an antenna state configuration and a sequence from a wireless access point (AP) device. A plurality of antenna states configured on the device may be selected based on the antenna state configuration and the sequence. An inertial measurement unit (IMU) measurement may be determined. A beacon signal may be transmitted for each selected antenna state. Each transmitted beacon signal may indicate a corresponding selected antenna state.
