Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, overlapped beam coverage areas between base stations cannot cooperate, leading to unreliable data transmission for users and decreased system throughput due to limited scheduling capabilities and increased scheduling delays.
Innovation Solution
A cooperative scheduling method and apparatus that acquires and determines configuration information for base stations in overlapped beam coverage areas, allowing for dynamic adjustment of beam coverage and resource allocation to fully utilize scheduling capabilities across the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If base stations in overlapped beam coverage areas operate independently without cooperation, then device complexity is reduced, but system throughput decreases and scheduling delays increase
Solution Approach 1:
The patent merges scheduling operations of multiple base stations by establishing a cooperative scheduling mechanism where base stations in overlapped coverage areas coordinate their scheduling decisions. The network device collects scheduling capability information from multiple base stations and generates unified configuration information that enables joint scheduling, thereby improving system throughput while managing complexity through centralized coordination.
Solution Approach 2:
The patent introduces a network device as an intermediary that facilitates cooperation between base stations. This mediator collects scheduling capability information from participating base stations, determines appropriate configuration information for cooperative scheduling, and distributes it to the base stations. This intermediary approach enables coordination without requiring direct complex interactions between all base station pairs.
2Reliability
If base stations in overlapped beam coverage areas operate independently, then scheduling coordination overhead is reduced, but data transmission reliability decreases
Solution Approach 1:
The patent implements preliminary action by having base stations pre-report their scheduling capability information to the network device before actual data transmission. The network device uses this advance information to determine and distribute configuration information for cooperative scheduling, enabling base stations to be ready for coordinated operation and reducing scheduling delays during actual transmission.
Solution Approach 2:
The patent establishes a feedback mechanism where base stations provide scheduling capability information to the network device, which then generates configuration information and feeds it back to the base stations. This closed-loop feedback enables the network to adaptively adjust cooperative scheduling parameters based on actual base station capabilities, improving both reliability and timing efficiency.
3Productivity
If base stations in overlapped beam coverage areas cooperate through centralized coordination, then resource utilization improves, but device complexity increases
Solution Approach 1:
The patent applies local quality by enabling cooperative scheduling only in specific overlapped coverage areas where it provides benefit, rather than requiring all base stations to participate in complex coordination. The network device identifies which base stations should cooperate based on their coverage overlap and scheduling capability information, applying coordinated scheduling locally where needed while maintaining independent operation elsewhere, thus improving resource utilization without universally increasing complexity.
