US 12,356,392 B2 · Mitigation of interference at a first user equipment based on information of scheduled uplink transmissions by a second user equipment

Abstract

Disclosed are techniques for communication. In an aspect, a first UE determines information (e.g., from an external device, or via the first UE's own energy sensing) associated with scheduled uplink transmissions on a set of symbols by a second UE. The first UE performs measurements on at least some of the scheduled uplink transmissions during a first subset of the set of symbols where no DL signals are received by the first UE. The first UE receives at least one DL signal during a second subset of the set of symbols, and mitigates interference associated with the at least one DL signal based on the measurements.

Dependent claims

A method of operating a first user equipment (UE), comprising:

determining information associated with a set of scheduled uplink transmissions to a serving base station on a set of symbols by a second UE;
performing one or more measurements associated with one or more of the set of scheduled uplink transmissions during a first subset of the set of symbols where no downlink (DL) signals are received by the first UE from the serving base station;
receiving at least one DL signal from the serving base station during a second subset of the set of symbols;
and
mitigating interference associated with the at least one DL signal based on the one or more measurements.
