Abstract: A method for expediting Secondary Cell (SCell) activation is proposed. Under the proposed enhanced direct SCell activation procedure, while adding an SCell to be activated state, the network can add transmission configuration indication (TCI) state information for the SCell in a radio resource control (RRC) signaling message, in addition to TCI state information for a list of candidate TCI states. Upon receiving the RRC signaling message, UE adds the SCell accordingly, and then activates the SCell based on the received TCI state information. Because there is no additional time required for receiving and processing the TCI state information via a media access control (MAC) control element (CE), the SCell activation time is reduced.

Abstract: Aspects of the disclosure provide an electronic device including processing circuitry and a method for radio resource management (RRM) measurements. The processing circuitry determines, based on a signal received in a serving cell for the electronic device, a location and mobility of the electronic device. The electronic device is in one of a first state and a second state for RRM measurements. A normal level of RRM measurements is implemented for one or more neighboring cells when the electronic device is in the first state, and a relaxed level of RRM measurements is implemented for the one or more neighboring cells when the electronic device is in the second state. The processing circuitry determines whether the electronic device is to be switched from the one of the first state and the second state to another of the first state and the second state based on the mobility and the location.

Abstract: A method for expediting Secondary Cell (SCell) or Primary cell of a secondary cell group (PSCell) addition or activation is proposed. A User Equipment (UE) receives a command that indicates adding or activating an SCell or a PSCell, wherein the command comprises information of a temporary Reference Signal (RS). The UE detects the temporary RS according to the information, and uses the temporary RS to add or activate the SCell or the PSCell.
