UE behavior in receiving aperiodic reference signals

A user equipment (UE), comprising:

• a memory comprising instructions;
• a transceiver;
• and
• one or more processors operatively coupled with the memory and the transceiver, the one or more processors configured to execute instructions in the memory to:
• receive downlink control information (DCI) indicating a first transmission of a plurality of aperiodic (AP) channel state information (CSI) reference signals (AP-CSI-RSs) and indicating a second transmission of downlink data;
• receive the plurality of AP-CSI-RSs and the downlink data, the reception of the plurality of AP-CSI-RSs indicating to the UE to transmit an AP-CSI report based on receiving the plurality of AP-CSI-RSs, wherein a last-in-time AP-CSI-RS of the plurality of AP-CSI-RSs is received before receiving a first orthogonal frequency division multiplexing (OFDM) symbol of the downlink data via a physical downlink shared channel (PDSCH) scheduled by the DCI;
• and
• refrain from transmitting the AP-CSI report indicated by the reception of the plurality of AP-CSI-RSs based on at least one of a change in a channel condition of the PDSCH for the downlink data or receiving the downlink data.

• and
• means for refraining from transmitting the AP-CSI report indicated by the reception of the plurality of AP-CSI-RSs based on at least one of a change in a channel condition of the PDSCH for the downlink data or receiving the downlink data.
