5G Terminal SCell Dormancy for Lower PDCCH Monitoring Power

The patent applies dynamics by making the monitoring state of secondary cells changeable between active and dormant states. The terminal dynamically adjusts its monitoring behavior based on received indications from the network side device, transitioning from continuous monitoring to reduced monitoring when in dormant state, thus adapting the system behavior to current traffic conditions to balance reliability and power consumption.

The patent implements periodic action by introducing specific monitoring occasions for secondary cells in dormant state. Instead of continuous monitoring, the terminal monitors PDCCH only at predetermined periodic intervals configured for dormant SCells, significantly reducing power consumption while maintaining adequate detection capability for resuming data transmission when needed.

The patent applies dynamics by enabling the terminal to switch between different monitoring states for secondary cells. When traffic activity is low, the terminal transitions to dormant state with reduced monitoring, extending operational time. When traffic activity increases or scheduling is needed, the terminal can quickly transition back to active state, maintaining fast scheduling response capability when required.

The patent implements self-service by enabling the terminal to autonomously manage its monitoring behavior based on received dormant SCell indications. The terminal independently determines which SCells to monitor and at what frequency based on network configurations and received indications, without requiring continuous network control, thus extending operational time while maintaining responsiveness.

The patent applies dynamics by enabling flexible activation and deactivation of secondary cell monitoring based on traffic demands. The terminal dynamically adjusts the number of active monitoring SCells rather than continuously monitoring all configured SCells, allowing the system to scale monitoring activity according to actual data transmission needs, thus balancing productivity and power consumption.

The patent implements local quality by applying different monitoring states to different secondary cells individually. Instead of uniformly monitoring all SCells, the network can indicate specific SCells to be in dormant state while others remain active, allowing localized optimization where each SCell's monitoring state matches its current traffic requirements, improving overall power efficiency while maintaining data transmission capacity where needed.
