Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in managing configuration deactivation for multiple user equipment (UEs) efficiently, particularly in complex and dynamic environments, leading to increased power consumption and potential disruptions in critical operations.
Innovation Solution
Implementing groupcast signaling to transmit information indicating a set of configurations to be deactivated, reducing overhead and preserving essential operations during cell discontinuous transmission or reception periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If individual UE-specific signaling is used to deactivate configurations, then precise control over each UE's configurations is achieved, but signaling overhead increases and network entity processing burden increases
Solution Approach 1:
The patent merges multiple UE-specific configuration deactivation signals into a single groupcast signal. The network entity transmits one groupcast signal containing deactivation information for multiple UEs simultaneously, eliminating the need for separate unicast signals for each UE. This combining approach reduces signaling overhead while maintaining the ability to precisely control configuration deactivation for each UE through individual identifiers within the groupcast message.
2Use of energy by moving object
If configurations are deactivated during cell discontinuous transmission or reception periods, then power consumption is reduced, but critical operations may be disrupted
Solution Approach 1:
The patent applies local quality by differentiating between configurations that can be deactivated and those that must be maintained. Within the groupcast deactivation signal, the network entity identifies specific configurations (such as SIB1 reception configuration) that should be preserved despite the discontinuous transmission period. This selective approach allows power savings through configuration deactivation while ensuring critical operations continue uninterrupted through explicit preservation indicators.
3Device complexity
If groupcast signaling is used to transmit configuration deactivation information, then signaling overhead is reduced, but the network entity must manage and process groupcast messages efficiently
Solution Approach 1:
The patent segments the groupcast deactivation signal into structured components that include individual UE identifiers, configuration types, and deactivation indicators. This segmentation allows the network entity to process the groupcast message efficiently by identifying and handling deactivation information for specific UEs only when necessary, rather than processing the entire message for all UEs. The structured format enables selective processing while maintaining reduced overhead benefits.
