Abstract: The present application at least describes a wireless transmit/receive unit (WTRU) including a processor and non-transitory memory including stored instructions which are executed by the processor. The instructions include receiving, from a base station, configuration information indicating a set of channel state information interference channel measurement (CSI-ICM) resources for the WTRU. The configuration information indicates a period and an offset for the set of CSI-ICM resources. The instructions also include receiving, from the base station, downlink control information (DCI) indicating a subset of the set of CSI-ICM resources. The instructions further include measuring the subset of CSI-ICM resources. The instructions even further include transmitting feedback to the base station based on the subset of CSI-ICM resources. The instructions yet even further include receiving a MAC control element (CE) indicating an activation of a CSI report from the base station.
