Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment without carrier aggregation capability faces challenges in maintaining optimal channel quality due to time-variant service distribution and channel conditions, leading to poor user experience and system performance.
Innovation Solution
A carrier switching method that allows user equipment to dynamically switch between carriers based on determined carrier switching policies, using information about carrier switching capability and network status to match service distribution and channel quality changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If user equipment operates only on a single carrier or a fixed pair of system-associated carriers, then device complexity is reduced and ease of operation is improved, but channel quality becomes time-variant and user experience deteriorates
Solution Approach 1:
The patent implements dynamic carrier switching by introducing a carrier switching policy that allows user equipment to transition between different carriers based on real-time network status and channel conditions. The base station determines switching policies and sends indication information to trigger carrier switching, transforming the static single-carrier operation into a dynamic multi-carrier switching mechanism that adapts to changing conditions while maintaining operational simplicity.
2Reliability
If user equipment dynamically switches between carriers, then channel quality and user experience are improved, but device complexity and control complexity increase
Solution Approach 1:
The patent introduces a base station as an intermediary that centralizes the carrier switching decision-making process. The base station determines carrier switching policies based on network status and sends indication information to user equipment, which then executes the switching. This intermediary approach transfers the complexity of policy determination from user equipment to the base station, reducing device complexity while enabling dynamic carrier switching for improved channel quality.
3Productivity
If carrier aggregation technology is used, then peak rate and productivity are improved, but device complexity increases and compatibility with legacy equipment is reduced
Solution Approach 1:
The patent implements a partial carrier aggregation approach by enabling user equipment to operate on multiple carriers through dynamic switching rather than simultaneous aggregation. The carrier switching policy allows UE to activate different carriers at different times based on service distribution and channel conditions, achieving improved peak rate and productivity while maintaining lower device complexity compared to full carrier aggregation, as UE only needs to handle one carrier at a time.
