Scell Dormancy Indication Across DRX Groups for Lower PDCCH Power

The patent segments the Scell group into multiple Scell sub-groups, where each sub-group can be independently controlled by separate dormancy indications. This segmentation allows different dormancy behaviors to be applied to different subsets of cells, thereby improving flexibility without significantly increasing overall system complexity through structured organization.

The patent introduces dynamic dormancy indication mechanisms where the network can flexibly configure and update dormancy parameters for different Scell sub-groups based on real-time conditions. This dynamic approach enables the system to adapt dormancy behavior to varying traffic patterns and channel conditions, enhancing versatility while maintaining manageable complexity through standardized procedures.

The patent implements periodic monitoring of PDCCH for dormancy indications, where terminals monitor at defined intervals rather than continuously. This periodic approach maintains adequate accuracy in determining dormancy states while significantly reducing power consumption compared to continuous monitoring, as terminals can enter low-power states between monitoring occasions.

The patent introduces configurable monitoring parameters such as monitoring periodicity and threshold values that can be adjusted based on traffic conditions. By dynamically changing these parameters, the system can balance between measurement precision and power consumption, allowing more frequent monitoring when accuracy is critical and less frequent monitoring when power savings are prioritized.
