Power-Efficient Multi-Link Activation in Mobile Communications

The patent applies dynamics by making the carrier activation state changeable rather than fixed. The UE dynamically switches between active and inactive states for secondary carriers based on data arrival conditions. When data is detected on the primary carrier, the UE activates secondary carriers; when no data is expected, the UE deactivates them. This dynamic state transition resolves the contradiction by allowing fast activation when needed while saving power during idle periods.

The patent applies partial action by having the UE monitor only the primary carrier continuously while performing partial or selective monitoring of secondary carriers. The UE monitors secondary carriers only when data is detected on the primary carrier, rather than continuously monitoring all carriers. This partial monitoring approach maintains data throughput capability while significantly reducing power consumption during idle periods.

The patent applies preliminary action by pre-configuring secondary carriers with necessary parameters and maintaining them in an inactive but quickly activatable state. The UE receives configuration information for secondary carriers in advance through RRC signaling, so when data arrives on the primary carrier, the activation process is expedited rather than starting from scratch. This preliminary preparation reduces activation delay without requiring continuous active monitoring.

The patent applies segmentation by dividing the carrier management into distinct functional segments: primary carrier for continuous monitoring and control, and secondary carriers for data transmission that are activated only when needed. This segmentation allows the UE to maintain CA or DC/MC configuration for high data transmission capability while managing complexity by separating always-active functions from conditional functions. The UE handles primary carrier management continuously and secondary carrier management event-driven.
