1. A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
receiving information related to a channel state information reference signal (CSI-RS) configuration for first panels and second panels;
measuring a CSI-RS using one or more panels of the first panels; and
in response to a triggering event:
sending a request to a base station to transmit a CSI-RS associated with one or more panels of the second panels;
activating the one or more panels of the second panels;
measuring the CSI-RS associated with the one or more panels of the second panels; and
identifying a panel having a CSI-RS measurement greater than a threshold and reporting the identified panel to the base station.
