Abstract
A user-equipment-coordination set in a cellular network includes multiple UEs for performing coordinated radar sensing. A first UE determines a configuration to coordinate other UEs to detect an object. The first UE uses the configuration to configure a second UE to transmit a first radar signal and a third UE to detect the first radar signal. The first UE receives first radar signal samples from the third UE based on the third UE receiving the first radar signal in multiple reflection states. The first UE filters the first radar signal samples to remove samples associated with interference from the first radar signal received in a first reflection state. The first UE determines object location information based on at least the filtered first radar signal samples.
Claims13
A method, by a first user equipment (UE) of a plurality of UEs in a cellular network, comprising:
- configuring, based on a configuration for coordinating the plurality of UEs to detect one or more objects, a second UE of the plurality of UEs to transmit, as a first radar signal, either a Sounding Reference Signal (SRS) or a Random Access Channel (RACH) signal utilized by the second UE for cellular signaling;
- sending, to a third UE of the plurality of UEs, a radar detection configuration message identifying one or more attributes associated with the first radar signal;
- receiving, from the third UE, first radar signal samples based on the third UE receiving the first radar signal in a plurality of reflection states;
- filtering the first radar signal samples to remove samples associated with the third UE receiving the first radar signal directly from the second UE;
- and
- responsive to filtering the first radar signal samples, determining object location information based on at least the filtered first radar signal samples.
