Abstract:
Systems and methods are disclosed for determining a first downlink control indicator (DCI) and a second DCI, determining a set of active aperiodic channel state information reference signals (A-CSI-RSs) based on the first DCI, and determining a subset of the set of active A-CSI-RSs based on the second DCI. A WTRU may perform resource element (RE) muting based on a set of active A-CSI-RSs. A WTRU may perform channel state information (CSI) measurement based on a subset of a set of active A-CSI-RSs.
