Embodiment Construction

[0020] Aspects of the present disclosure provide techniques for determining the relative rotation of a wireless device to another device based on relative antenna gain and / or phase of training signals sent from antennas with different polarizations (e.g., horizontal and vertical) . Such techniques may offer various advantages over measurements from mechanical sensors and, in some cases, may be used to verify or enhance such measurements.

[0021] Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms, and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. Based on the teachings herein, those skilled in the art should apprecia...

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.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims the benefit of U.S. Provisional Patent Application No. 62 / 084,104, filed November 25, 2014, and U.S. Application No. 14 / 919,389, filed October 21, 2015, which are hereby incorporated by reference. The entire contents of both applications are expressly incorporated herein. technical field [0003] In general, the present invention relates to millimeter wave radio frequency (RF) systems, and in particular, the present invention relates to the operation of phased array antennas in such radio modules to allow efficient signal propagation. Background technique [0004] The 60GHz frequency band is a license-exempt frequency band with a large amount of bandwidth and worldwide overlap. High bandwidth means that very large amounts of information can be sent wirelessly. As a result, many applications requiring the transmission of very large amounts of data may be developed to allow wireless comm...
