Abstract:
An embodiment method, by a user equipment (UE), includes performing a channel measurement (CM) on a first subset of a set of non-zero-power (NZP) CSI reference signal (CSI-RS) resources and an interference measurement (IM) on at least a second subset of the set of NZP CSI-RS resources. The second subset includes one or more NZP CSI-RS ports. The IM is performed according to assumptions: each NZP CSI-RS port in the second subset corresponds to an interference transmission layer, the IM being in accordance with a set of energy per resource element ratios each associated with one NZP CSI-RS resource in the second subset; and other interference not associated with the interference transmission layers is on the first and second subsets. The method includes generating a channel state information (CSI) report based on the CM and IM and transmitting the CSI report to a network.

Abstract:
A method and apparatus for triggering activation of a secondary cell (SCell) and activating the SCell is provided. A user equipment (UE) may receive, from a gNB, a SCell activation command indicating the UE to activate a SCell for communications between the UE and the gNB on the SCell, and receive a reference signal (RS) on the SCell. The RS is configured for activation of the SCell. The UE may perform, upon receiving the SCell activation command, SCell activation for activating the SCell based at least on the RS, and send, to the gNB, a report indicating that the SCell is activated for the UE.
