1. A method for wireless communication of a first wireless device, comprising:
- receiving at least one signal from a second wireless device, the at least one signal including one or more of round-trip phase (RTP) information or inertial sensor information;
determining at least one angle-of-arrival (AoA) measurement and at least one RTP measurement associated with the at least one signal received from the second wireless device;
determining a path of trajectory of the second wireless device based on the inertial sensor information and at least in part on the at least one AoA measurement and the at least one RTP measurement;
determining orientation information of the second wireless device based at least in part on the inertial sensor information;
determining tilt information associated with the second wireless device based at least in part on the inertial sensor information;
de-rotating an accelerometer component of the inertial sensor information and removing a gravity component of the acceleration information to generate de-rotated and gravity free acceleration information based at least in part on the tilt information; and
integrating the de-rotated and gravity free acceleration information to determine sensor derived trajectory information.
