Abstract
Disclosed are techniques for wireless sensing. In an aspect, a transmitter device transmits, to at least one receiver device, one or more reference signals on each of a plurality of transmit beams, wherein the plurality of transmit beams corresponds to a plurality of codepoints of a near-field codebook, and wherein each of the plurality of codepoints is parameterized with an angle value and a range value of a corresponding transmit beam of the plurality of transmit beams.
Claims17
A method of wireless sensing performed by a transmitter device, comprising:
- receiving a request from a sensing server to perform near-field sensing;
- and
- transmitting, to at least one receiver device, in response to the request, one or more reference signals on each of a plurality of transmit beams, wherein the plurality of transmit beams corresponds to a plurality of codepoints of a near-field codebook, and wherein each of the plurality of codepoints is parameterized with an angle value and a range value of a corresponding transmit beam of the plurality of transmit beams.
A transmitter device, comprising:
- one or more memories;
- one or more transceivers;
- and
- one or more processors communicatively coupled to the one or more memories and the one or more transceivers, the one or more processors, either alone or in combination, configured to:
- receive, via the one or more transceivers, a request from a sensing server to perform near-field sensing;
- and
- transmit, via the one or more transceivers, to at least one receiver device, in response to the request, one or more reference signals on each of a plurality of transmit beams, wherein the plurality of transmit beams corresponds to a plurality of codepoints of a near-field codebook, and wherein each of the plurality of codepoints is parameterized with an angle value and a range value of a corresponding transmit beam of the plurality of transmit beams.
