Dual Cell Scheduling Fallback When a Secondary Cell Is Unavailable
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual scheduling configurations in wireless communications networks are limited in certain configurations, particularly when a secondary cell is not available.
Innovation Solution
A method and apparatus for user equipment to operate in a dual scheduling configuration, determining the availability of a secondary cell, and switching to a single scheduling configuration if the secondary cell is not available, with the primary cell being scheduled only by the primary cell.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If dual scheduling configuration is used to allow primary cell to be scheduled by primary cell or secondary cell, then scheduling flexibility and resource allocation efficiency are improved, but system complexity and configuration limitations increase when secondary cell is not available
Solution Approach 1:
The patent implements dynamic switching between dual scheduling configuration (when secondary cell is available) and single scheduling configuration (when secondary cell is not available). The system adapts its scheduling mode based on the availability status of the secondary cell, allowing the primary cell to be scheduled by either primary cell or secondary cell in dual mode, and automatically falling back to primary cell-only scheduling in single mode. This dynamic adaptation resolves the contradiction by maintaining high scheduling efficiency while managing configuration complexity through conditional mode switching.
2Adaptability or versatility
If dual scheduling configuration is used, then resource allocation flexibility is improved, but reliability decreases when secondary cell becomes unavailable
Solution Approach 1:
The patent prepares for secondary cell unavailability by implementing a pre-configured fallback mechanism. The system is designed with the capability to switch from dual scheduling to single scheduling mode before actual failures occur, ensuring continuous operation. When the secondary cell becomes unavailable, the system has already established the single scheduling configuration as a backup, maintaining connection reliability without service interruption.
Solution Approach 2:
The patent changes the scheduling configuration parameter based on secondary cell availability status. In dual scheduling mode, the primary cell can receive scheduling from both primary and secondary cells, maximizing resource allocation flexibility. When secondary cell becomes unavailable, the parameter changes to single scheduling mode where primary cell is scheduled only by itself, maintaining reliable operation with available resources.
3Stability of the object's composition
If the system switches from dual scheduling to single scheduling when secondary cell is unavailable, then operational stability is improved, but scheduling efficiency decreases
Solution Approach 1:
The system dynamically adjusts the scheduling configuration based on real-time secondary cell availability. When secondary cell is available, dual scheduling provides high efficiency with both cells participating in scheduling. When secondary cell becomes unavailable, the system transitions to single scheduling mode to maintain stability. This dynamic adjustment resolves the contradiction by optimizing for efficiency when possible and stability when necessary.
