## Abstract

Various aspects of the present disclosure relate to reporting differential measurement quantities for an antenna array. An apparatus, such as a first device, which may be a sensing transmitter (Tx) node, a user equipment (UE), a network equipment (NE), or another device, may receive a sensing signal from a second device. The first device may determine a differential measurement quantity based on the sensing signal. The differential measurement quantity may indicate 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. The first reference point and the second reference point may be associated with one or more antenna arrays of the first device. The first device may transmit a report including the differential measurement quantity.
