Patent ID: 11109257

Abstract:
A wireless transmit/receive unit (WTRU) may receive configuration information indicating a plurality of sets of resource elements (REs). Each of the plurality of sets of REs may be associated with a Channel-State-Information Reference Signal (CSI-RS) configuration. Also, the WTRU may receive a request in a Downlink Control Information (DCI) signal, in a first time unit, to receive at least one CSI-RS, in at least one set of the plurality of sets of REs, in the first time unit, to perform a measurement and to report the measurement; and the request may indicate the at least one set of the plurality of sets of REs. Further, the WTRU may receive the at least one CSI-RS, in the at least one set of the plurality of sets of REs, in the first time unit, according to the request. Moreover, the WTRU may perform the measurement of the at least one CSI-RS.
