Reporting differential measurement quantities for an antenna array

A processor for wireless communication, comprising:

• at least one controller coupled with at least one memory and operable to cause the processor to:
• receive, from a second device, a sensing signal;
• determine a differential measurement quantity based on the sensing signal, wherein the differential measurement quantity indicates a difference between a first measurement of a first channel segment associated with the first device at a first reference point and a second measurement of a second channel segment associated with the first device at a second reference point, and wherein the first reference point and the second reference point are associated with one or more antenna arrays of the first device;
• and
• transmit, to the second device, a report including the differential measurement quantity.

A method performed by a first device, the method comprising:
