Secondary cell activation status reporting

A method for wireless communications at a user equipment (UE), comprising:

• receiving an indicator of an activation of one or more secondary cells configured for the UE;
• performing at least a portion of a synchronization procedure, one or more channel state information (CSI) measurements, or both, for the one or more secondary cells in accordance with the activation of the one or more secondary cells;
• transmitting, via an uplink control information message, a status indication for the one or more secondary cells that indicates completion of the synchronization procedure, the one or more CSI measurements, or both;
• and
• receiving a message that requests aperiodic CSI reporting from the UE of the one or more secondary cells based at least in part on transmission of the status indication.
