Zero power (zp) channel state information reference signal (csi-rs) rate matching with slot aggregation

An apparatus for wireless communications, comprising:

• a receiver configured to receive, in a first slot of a plurality of aggregated slots, a first indication in downlink control information (DCI) that triggers a set of zero power (ZP) channel state information reference signal (CSI-RS) resources from multiple sets of ZP CSI-RS resources;
• at least one processor configured to:
• determine, based at least in part on the first indication received in the first slot of the plurality of aggregated slots, a rate matching behavior for processing a physical downlink shared channel (PDSCH) transmission received in the first slot and at least a second slot, subsequent to the first slot, of the plurality of aggregated slots;
• and
• process the PDSCH transmission received in the first slot and at least the second slot in accordance with the rate matching behavior;
• and
• a memory coupled to the at least one processor.

A method for wireless communication by a network entity, comprising:

• determining a rate matching behavior for processing a physical downlink shared channel (PDSCH);
• transmitting, to a user equipment (UE), a first indication via downlink control information (DCI) that triggers a set of zero power (ZP) channel state information reference signal (CSI-RS) resources from multiple sets of ZP CSI-RS resources, wherein the first indication is transmitted in a first slot of a plurality of aggregated slots;
• and
• transmitting the PDSCH in the first slot and at least a second slot, subsequent to the first slot, of the plurality of aggregated slots, wherein the determined rate matching behavior for processing the PDSCH transmitted in the first slot and at least the second slot is based in part on the first indication transmitted in the first slot.
