1. A method of wireless communication at a scheduling entity of a primary cell (PCell), comprising:

  • transmitting carrier aggregation (CA) capability information to a user equipment (UE);

    transmitting, to the UE, secondary cell (SCell) pre-configuration information for facilitating an accelerated SCell activation procedure based on the CA capability information of the UE;

    transmitting, to the UE, a control message to initiate the accelerated SCell activation procedure to establish a connection between the UE and one or more SCells;

    controlling the one or more SCells to transmit respective UE-specific reference signals based on the SCell pre-configuration information; and

    receiving, from the UE, a measurement report of the UE-specific reference signals indicating a preference of the one or more SCells for a CA configuration.
