Abstract: This disclosure provides systems, methods and apparatuses that support channel state information (CSI) reporting techniques for secondary cell (SCell) activation. A user equipment (UE) may receive one or more medium access control-control elements (MAC-CEs) that indicate a secondary cell (SCell) activation command, an aperiodic tracking reference signal (AP-TRS) trigger, and an aperiodic channel state information (AP-CSI) report trigger. The network entity may signal the SCell activation command, the AP-TRS trigger, and the AP-CSI report trigger in the same MAC-CE or in separate MAC-CEs. The UE may receive and measure AP-TRS in accordance with the AP-TRS trigger indicated by the one or more MAC-CEs, and may perform measurements via an aperiodic channel measurement resource (AP-CMR) and an aperiodic interference measurement resource (AP-IMR) in accordance with the AP-CSI report trigger indicated by the one or more MAC-CEs.

Abstract: Aspects of the present disclosure allow for more efficient rate matching by allowing a triggered A-ZP-CSI-RS set to support rate matching around multiple slots. Aspects of the present disclosure may allow a triggered A-ZP CSI-RS set to be applied to less than all scheduled PDSCH slots when DCI schedules PDSCH on multiple slots.

In addition, aspects of the present disclosure can also add periodicity to A-ZP-CSI-RS resource set configuration.
