Abstract
Various aspects of the disclosure relate to millimeter wave ranging with six degrees of freedom. For example, a multi-gigabyte link (e.g., an IEEE 802.11ad link or an 802.11ay link) and RF/Antenna diversity modules can be used to conduct round trip time (RTT) distance measurements between an anchor point and a station. Relative location information (e.g., degrees of freedom) between the wireless devices can then be determined based on the distance measurements.
Claims22
An apparatus for communication, comprising:
- an interface configured to obtain a plurality of signals;
- and
- a processing system configured to:
- estimate a plurality of distances between a first plurality of antennas and a second plurality of antennas based on the plurality of signals,
- determine six degrees of freedom between the apparatus for communication and another apparatus based on the plurality of distances, and
- generate an indication of the six degrees of freedom,
- wherein the interface is further configured to output the indication.
A method of communication, comprising:
- obtaining a plurality of signals;
- estimating a plurality of distances between a first plurality of antennas and a second plurality of antennas based on the plurality of signals;
- determining six degrees of freedom between an apparatus and another apparatus based on the plurality of distances;
- generating an indication of the six degrees of freedom;
- and
- outputting the indication.
20-32. (canceled)
A wireless node, comprising:
- a first plurality of antennas;
- a receiver configured to receive a plurality of signals via the first plurality of antennas;
- a processing system configured to:
- estimate a plurality of distances between the first plurality of antennas and a second plurality of antennas based on the plurality of signals,
- determine six degrees of freedom between the wireless node and another wireless node based on the plurality of distances, and
- generate an indication of the six degrees of freedom;
- and
- an interface configured to output the indication.
