Zero power (ZP) channel state information reference signal (CSI-RS) rate matching with slot aggregation

Abstract:

Techniques and apparatus for rate matching physical downlink shared channel (PDSCH) around zero power (ZP) channel state information reference signal (CSI-RS) resources in slot aggregation scenarios are described. In one technique, an indication that triggers a set of ZP CSI-RS resources is received in a first slot of a plurality of aggregated slots. A rate matching behavior for processing a PDSCH transmission received in the first slot and at least a second slot, subsequent to the first slot, of the plurality of aggregated slots is determined. The PDSCH transmission received in the first slot and at least the second slot is processed in accordance with the rate matching behavior.
