1. A wireless transmit/receive unit (WTRU) comprising:
a processor and a transceiver configured to receive configuration information indicating a value for a timer associated with feedback reporting;
the processor and the transceiver configured to receive information indicating a presence of a channel state information reference signal (CSI-RS) transmission resource and indicating a request for a feedback report including feedback associated with the CSI-RS transmission resource;
the processor configured to determine a validity of a feedback report based on a time between the CSI-RS transmission resource and a feedback report resource and based on the timer associated with feedback reporting; and
the processor and the transceiver configured to, based on a determination that the feedback report is valid, transmit the feedback report in the feedback report resource.
