TCI State Deactivation for Wireless Resource Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices continue to consume resources by maintaining active transmission configuration indicator (TCI) states even when they are not utilized for communications, leading to undesirable resource consumption.
Innovation Solution
A method and apparatus for a user equipment (UE) to receive an indication from a network entity to deactivate all TCI states associated with indicated cells, allowing the UE to conserve resources by refraining from performing operations associated with unused TCI states, and to activate TCI states for candidate cells when necessary for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE activates and maintains multiple TCI states for candidate cells, then the UE is prepared for potential cell switching and communication flexibility, but the UE consumes unnecessary resources by performing operations on TCI states that are not utilized
Solution Approach 1:
The patent implements dynamic TCI state management where the UE can switch between different sets of TCI states based on actual communication needs. The network entity dynamically activates or deactivates TCI states associated with candidate cells through signaling messages, allowing the UE to adapt its resource allocation in real-time rather than maintaining all TCI states continuously.
Solution Approach 2:
The patent applies selective activation of TCI states on a per-cell basis. Instead of uniformly maintaining all TCI states, the system identifies which candidate cells actually require TCI state activation based on local communication conditions, and only activates TCI states for those specific cells, thereby optimizing resource usage.
2Reliability
If the UE continues to perform operations on activated TCI states, then the UE maintains readiness for communication, but the UE wastes resources on TCI states that are not utilized for actual communications
Solution Approach 1:
The network entity provides feedback through signaling messages that indicate whether TCI states should be activated or deactivated. This feedback mechanism allows the system to adjust TCI state activation based on actual communication requirements, ensuring that resources are allocated efficiently while maintaining communication readiness where needed.
Solution Approach 2:
The system performs preliminary activation of TCI states for candidate cells when cell switching is anticipated, but the UE can refrain from performing full operations on TCI states unless actually needed. This allows the system to be prepared for communication while avoiding unnecessary resource consumption on unused TCI states.
3Adaptability or versatility
If the network entity configures multiple candidate cells with TCI states, then the system provides scheduling flexibility and communication options, but the UE must manage and process multiple TCI state configurations
Solution Approach 1:
The patent segments the management of TCI states by cell, allowing the UE to handle each candidate cell's TCI states independently. The network entity provides cell-specific configuration information, and the UE processes TCI states on a per-cell basis rather than managing all TCI states as a single complex entity, thereby reducing overall management complexity.

AI summary
A user equipment (UE) may receive, from a network entity, a configuration of one or more candidate cells for switching to from a serving cell. The UE may receive, from the network entity, an indication to deactivate all transmission configuration indicator (TCI) states associated with one or more indicated cells. The UE may deactivate the all TCI states associated with the one or more indicated cells based at least in part on receiving the indication to deactivate the all TCI states. One or more of the one or more candidate cells or the serving cell may include the one or more indicated cells.
