Abstract

Various aspects of the present disclosure generally relate to wireless communication. A user equipment (UE) may receive a downlink communication triggering an aperiodic cross-link interference (CLI) measurement in accordance with a quasi-co-location (QCL) Type-D configuration. The UE may perform the aperiodic CLI measurement using one or more reference signals received in accordance with the downlink communication. For example, the UE may perform the aperiodic CLI measurement using the default receive beam. The UE may report the results of the aperiodic CLI measurement in an aperiodic CLI report.

Claims20

Dependent claims

An apparatus for wireless communication at a user equipment (UE), comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories, at least one processor of the one or more processors configured to cause the UE to:
receive a quasi-co-location (QCL) configuration that associates one or more transmission configuration indicator (TCI) states with a QCL type D;
receive a physical downlink control channel (PDCCH) communication carrying downlink control information (DCI) associated with one or more aperiodic UE-to-UE cross-link interference (CLI) measurement resources corresponding to the one or more TCI states;
receive one or more CLI measurement signals in accordance with a scheduling offset between a last symbol of the PDCCH communication carrying the DCI and a first symbol of the one or more aperiodic UE-to-UE CLI measurement resources satisfying, or not satisfying, a UE-reported beam switch timing threshold;
and
transmit an aperiodic CLI report in accordance with the one or more CLI measurement signals.

5 more elements

A method of wireless communication performed at a user equipment (UE), comprising:

receiving a quasi-co-location (QCL) configuration that associates one or more transmission configuration indicator (TCI) states with a QCL type D;
receiving a physical downlink control channel (PDCCH) communication carrying downlink control information (DCI) associated with one or more aperiodic UE-to-UE cross-link interference (CLI) measurement resources corresponding to the one or more TCI states;
receiving one or more CLI measurement signals in accordance with a scheduling offset between a last symbol of the PDCCH communication carrying the DCI and a first symbol of the one or more aperiodic UE-to-UE CLI measurement resources satisfying, or not satisfying, a UE-reported beam switch timing threshold;
and
transmitting an aperiodic CLI report in accordance with the one or more CLI measurement signals.
