Technique for obtaining the rotation of a wireless device
First Claim
1. A first apparatus for wireless communications, comprising:
- a first interface for obtaining, via at least one receive antenna, first and second training signals transmitted from a second apparatus via at least first and second transmit antennas having different polarizations; and
a processing system configured to;
determine, based on the first and second training signals, one or more characteristics for different transmit-receive antenna pairs, each pair comprising one of the first and second transmit antennas and the at least one receive antenna,generate, based on the one or more characteristics, a parameter indicative of a rotation of the first apparatus relative to the second apparatus, andadjust the parameter based on the one or more characteristics.

Abstract
Certain aspects of the present disclosure relate to methods and apparatus for wireless communication. More particularly, aspects of the present disclosure generally relate to techniques for wireless communications by a first apparatus comprising a first interface for obtaining, via at least one receive antenna, first and second training signals transmitted from a second apparatus via at least first and second transmit antennas having different polarizations, and a processing system configured to determine, based on the first and second training signals, one or more characteristics for different transmit-receive antenna pairs, each pair comprising one of the first and second transmit antennas and the at least one receive antenna, and generate, based on the one or more characteristics, a parameter indicative of a rotation of the first apparatus relative to the second apparatus.
