Abstract

This disclosure provides systems, methods, and apparatuses for wireless communication. In some aspects, an example method includes receiving, from a second wireless communication device, a frame associated with one or more wireless sensing measurements, verifying an integrity of the received frame associated with a message integrity code (MIC) in the received frame, and obtaining one or more wireless sensing measurements associated with the received frame.

First claim

What is claimed is:

1 . A first wireless communication device, comprising:
an interface configured to:
obtain a frame associated with one or more wireless sensing measurements;
a processing system configured to:
verify an integrity of the frame associated with a message integrity code (MIC) in the frame; and
the interface further configured to:
obtain one or more wireless sensing measurements associated with the frame.

2 . The first wireless communication device of claim 1 , wherein the MIC is configured to protect the integrity of a timestamp of the frame.

3 . The first wireless communication device of claim 2 , wherein verifying the integrity of the frame comprises validating the timestamp with the MIC.

4 . The first wireless communication device of claim 2 , wherein verifying the integrity of the frame is associated with a difference between an arrival time of the frame and the timestamp.

5 . The first wireless communication device of claim 4 , wherein verification of the integrity of the frame is associated with the difference between the arrival time of the frame and the timestamp being less than a threshold time.

6 . The first wireless communication device of claim 5 , further comprising refraining from verifying the integrity of the frame when the difference is greater than the threshold time.

7 . The first wireless communication device of claim 5 , wherein the threshold time is associated with an estimated propagation time of the frame.

8 . The first wireless communication device of claim 1 , wherein verifying the integrity of the frame includes validating an entirety of one or more media access control (MAC) protocol data units (MPDUs) associated with the frame.

9 . The first wireless communication device of claim 1 , wherein verifying the integrity of the frame includes validating one or more aggregated physical layer (PHY) protocol data units (A-PPDUs) associated with the frame.

10 . The first wireless communication device of claim 1 , further comprising establishing a wireless sensing session with at least a second wireless communication device prior to receiving the frame, wherein the frame is obtained from the second wireless communication device.

11 . A method for wireless communication by a first wireless communication device, comprising:
receiving a frame associated with one or more wireless sensing measurements; verifying an integrity of the received frame associated with a message integrity code (MIC) in the received frame; and receiving one or more wireless sensing measurements associated with the received frame.

12 . The method of claim 11 , wherein the MIC is configured to verify the integrity of a timestamp of the received frame.

13 . The method of claim 12 , wherein verifying the integrity of the received frame comprises validating the timestamp with the MIC.

14 . The method of claim 12 , wherein verifying the integrity of the received frame is associated with a difference between an arrival time of the frame and the timestamp.

15 . The method of claim 14 , wherein verification of the integrity of the received frame is associated with the difference between the arrival time of the frame and the timestamp being less than a threshold time.

16 . The method of claim 11 , wherein verifying the integrity of the received frame includes validating an entirety of one or more media access control (MAC) protocol data units (MPDUs) associated with the received frame.

17 . The method of claim 11 , wherein verifying the integrity of the received frame includes validating one or more aggregated physical layer (PHY) protocol data units (A-PPDUs) associated with the received frame.

18 . The method of claim 11 , further comprising, establishing a wireless sensing session with at least a second wireless communication device prior to receiving the frame, wherein the frame is received from the second wireless communication device.

19 . A non-transitory computer-readable storage medium storing instructions, that, when executed by one or more processors of a first wireless communication device, cause the first wireless communication device to perform operations comprising:
receiving a frame associated with one or more wireless sensing measurements; verifying an integrity of the received frame associated with a message integrity code (MIC) in the received frame; and receiving one or more wireless sensing measurements associated with the received frame.

20 . The non-transitory computer-readable storage medium of claim 19 , wherein the MIC is configured to protect the integrity of a timestamp of the received frame, and wherein verifying the integrity of the frame comprises validating the timestamp with the MIC.
