    摘要： A method of L1/L2-based mobility with signaling optimization using base (reference) configuration and replaceable (delta) configuration for candidate cells is proposed. All candidates can be configured at different levels provided by Radio Resource Control (RRC) signaling. To support L1/L2-triggered mobility (LTM), there is a common base configuration for candidates, and the candidates are modelled as replaceable configurations which are delta configurations on top of the common base configuration (instead of UE's current RRC configuration). The common and replaceable configurations are also referred to as reference configuration and candidate delta configuration. The candidate delta configuration is applied on top of the reference configuration to form a complete candidate configuration for handover.

    摘要： In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. In certain configurations, the UE enters a first radio resource control (RRC) connection with a first base station of a first network. The UE receives, from the first base station, an indication that enables the UE to send a first request for deactivating or releasing resources used for communications with the first base station. In response to a determination to enter a second RRC connection with a second base station of a second network, the UE sends, to the first base station, the first request for deactivating or releasing the resources. The UE enters the second RRC connection with the second base station while maintaining the first RRC connection with the first base station.

    摘要： A method of UE-initiated radio resource control, RRC, connection release procedure in LTE/5G network is proposed. A UE is required to establish RRC connection and enter RRC_Connected state for data communication (501). However, power consumption from functions for UE mobility can be significant, especially in RRC_Connected state. It is thus desirable for the UE to be able leave the RRC_Connected state (503, 504) by triggering an RRC connection release procedure (502). The triggering conditions may include: 1) UE has no data transmission for quite some time; 2) UE is in low battery status; 3) UE has incoming voice/video call from another USIM; or 4) UE has outgoing voice/video call in another USIM.

    摘要： Aspects of the disclosure provide a method to activate secondary cell group (SCG) selectively. For example, the method can include receiving a radio resource control (RRC) reconfiguration message including first and second radio resource configurations of first and second primary secondary cells (PSCells) and conditional PSCell addition (CPA) and conditional PSCell change (CPC) triggering conditions, setting a current triggering condition to be the CPA triggering condition, evaluating the current triggering condition and determining that the first PSCell satisfies the current triggering condition, and performing a CPA step to add the first PSCell as a current SCG, updating the current triggering condition to be the CPC triggering condition, the UE still keeping the first and second radio resource configurations and the CPA and CPC triggering conditions for subsequent CPC step, without releasing the second radio resource configuration and the CPA and CPC triggering conditions associated with the second PSCell.
