Timing Advance Configuration for Multi-Beam 5G Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing configuration methods for timing advance information in multi-beam/multi-station transmission in 5G wireless communication systems face challenges due to large time delay differences and the coexistence of eMBB and URLLC services, leading to low transmission performance, as traditional single timing advance methods are inadequate for handling multiple transmissions and differing service configurations.
Innovation Solution
A method and device for configuring timing advance information, where a first transmission node indicates timing advance information through signaling to multiple second transmission nodes, allowing each node to configure timing advance information for multiple transmission links, addressing the limitations of single TA methods by enabling flexible and service-specific configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single timing advance information is configured for uplink transmission, then the configuration is simple, but it cannot handle multiple transmissions with different path delays in multi-beam/multi-station scenarios
Solution Approach 1:
The patent segments the single timing advance information into multiple timing advance information sets, each corresponding to different transmission links or beams. This allows each link to have its own timing advance value, resolving the contradiction by maintaining simplicity through structured organization while achieving versatility through multiple configurable parameters.
Solution Approach 2:
The patent introduces a new dimension of timing advance configuration by associating different timing advance information with different transmission links, beams, or service types. This dimensional expansion allows the system to handle multi-beam/multi-station scenarios without significantly increasing overall configuration complexity.
2Device complexity
If timing advance information is shared among different services (eMBB and URLLC), then the configuration is simplified, but transmission performance degrades due to different service requirements
Solution Approach 1:
The patent applies local quality by allowing different timing advance information to be configured for different services (eMBB and URLLC) based on their specific requirements. This enables optimized timing advance values for each service type, improving transmission performance while maintaining manageable configuration complexity through service-specific customization.
Solution Approach 2:
The patent changes the timing advance parameter configuration by introducing service-specific timing advance information. This allows the system to adjust timing advance values according to different service characteristics (latency requirements, reliability needs), resolving the contradiction between simplified configuration and optimized performance.
3Reliability
If multiple timing advance information are configured for different transmission links, then transmission performance is improved, but the configuration complexity increases
Solution Approach 1:
The patent creates a universal timing advance configuration framework that can handle multiple transmission links, beams, and service types through a unified structure. This multi-functional approach improves transmission performance by enabling precise timing control for each link while avoiding excessive complexity through standardized configuration mechanisms.
