Reference signal for cross-link interference measurement

A method for wireless communications at a base station, comprising:

• transmitting, to a first user equipment (UE), a cross-link interference measurement configuration which provides a cross-link interference measurement resource for measurement by the first UE of cross-link interference from an aggressor UE;
• transmitting, to the first UE, an indication of a reference cell to be used by the first UE for estimation of a cross-link interference measurement resource timing;
• and
• receiving a cross-link interference report from the first UE which includes one or more cross-link interference measurements made by the first UE on the cross-link interference measurement resource and in accordance with the cross-link interference measurement resource timing.

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

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive a cross-link interference measurement configuration which provides a cross-link interference measurement resource for the UE for measurement of cross-link interference from an aggressor UE;
• select, based at least in part on a selection priority, a reference cell for estimation of a cross-link interference measurement resource timing;
• determine a reference cell timing based on a reference signal of the reference cell;
• estimate the cross-link interference measurement resource timing based at least in part on the reference cell timing;
• and
• measure cross-link interference from the aggressor UE in accordance with the cross-link interference measurement resource timing.
