Component Carrier Scheduler for Wireless UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in managing and optimizing finite wireless channel resources due to signal attenuation and blocking in complex environments, particularly in scheduling multiple component carriers across different frequency ranges with limited radio frequency chains.
Innovation Solution
A method for user equipment (UE) to select component carriers in both first and second frequency ranges, determine a schedule for search and measurement, and perform these operations according to the schedule, allowing for flexible scheduling and power savings while meeting timing requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If search and measurement are performed in all component carriers, then measurement accuracy is improved, but power consumption increases
Solution Approach 1:
The patent segments the component carriers into two groups: a first set of CCs where search and measurement are performed, and a second set of CCs where search and measurement are skipped. This segmentation allows the UE to focus measurement resources on critical carriers while conserving power on less critical ones, directly resolving the contradiction between measurement accuracy and power consumption.
Solution Approach 2:
The patent extracts the search and measurement operations from the second set of component carriers entirely. By taking out these operations from non-critical CCs and performing them only on the first set of CCs, the system maintains necessary measurement accuracy while significantly reducing power consumption associated with exhaustive measurement across all carriers.
2Use of energy by moving object
If search and measurement are skipped in some component carriers, then power consumption is reduced, but measurement coverage deteriorates
Solution Approach 1:
The patent applies local quality by differentiating measurement requirements across different component carriers. The first set of CCs receives full search and measurement operations to ensure comprehensive coverage where needed, while the second set of CCs has these operations skipped to conserve power where full measurement coverage is less critical. This localized approach resolves the contradiction between power consumption and measurement coverage.
3Productivity
If multiple component carriers are scheduled, then system capacity is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic scheduling where the network can flexibly configure which component carriers belong to the first set (requiring search and measurement) and which belong to the second set (skipping search and measurement). This dynamic approach allows the system to maintain high capacity by scheduling multiple CCs while managing complexity through adaptive configuration rather than fixed exhaustive measurement procedures.
