Accelerated cell activation in wireless communication
First Claim
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.

Abstract
Aspects of the present disclosure provide various procedures and methods for accelerated secondary cell (SCell) activation when carrier aggregation (CA) is configured. A scheduling entity receives, from a network entity, an indication of anticipated data for a user equipment (UE) in an idle mode. The scheduling entity determines supplemental wake-up information based on the carrier aggregation capability of the PCell. The scheduling entity transmits a wake-up message to the UE. The wake up message is configured to cause the UE to wake up in a CA configuration using the PCell and one or more SCells, based on the supplemental wakeup information.
