7. A method performed by a wireless transmit/receive unit (WTRU) for receiving a physical downlink shared channel (PDSCH) transmission, the method comprising:
receiving configuration information for a channel state information reference signal (CSI-RS), wherein the configuration information indicates one or more CSI-RS resources;
receiving scheduling information for reception of the PDSCH transmission, wherein the scheduling information indicates PDSCH resources, wherein the PDSCH resources include a first number of resources and a second number of resources, and
wherein the first number of resources overlaps with at least a CSI-RS resource from the one or more CSI-RS resources; and
receiving the PDSCH transmission using the first number of resources and the second number of resources when the CSI-RS is an aperiodic non-zero power CSI-RS (NZP-CSI-RS).
