  • Publication number: 20240114419
    Abstract: Examples pertaining to secure transmission in mobile communications are described. A UE receives an RRC reconfiguration message from a master network node. The RRC reconfiguration message comprises information regarding candidate cells and predefined reconfigurations, and each candidate cell is associated with one predefined reconfiguration. The UE evaluates a triggering condition for at least one candidate cell to determine whether to trigger a conditional cell change procedure and performs the conditional cell change procedure to switch a PSCell associated with the apparatus to a target cell in an event that the triggering condition for the target cell is met. The UE derives a security key according to a counter value and a key of the master network node. The counter value is obtained from a sequence of distinct counter values of the target cell or of a target secondary node stored by the processor or is generated by the processor.

  • Publication number: 20240049085
    Abstract: 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.
