Base Station Transmission Path Configuration for 5G Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, determining optimal transmission paths for Dual-Connectivity scenarios is challenging due to varying quality of service (QoS) and path state conditions, leading to inefficiencies in resource utilization and reliability, especially for URLLC services.
Innovation Solution
A method and base station configuration that dynamically determines and manage multiple transmission paths for terminals based on QoS and path state information, using artificial intelligence models to group terminals and select paths with high signal quality, and activate packet duplication mechanisms as needed, to ensure QoS requirements are met.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple transmission paths are configured for terminals in Dual-Connectivity scenarios, then communication reliability is improved, but device complexity and resource utilization efficiency deteriorate
Solution Approach 1:
The patent segments terminals into different groups based on their QoS requirements and service types. By dividing the terminal population into segments (e.g., URLLC terminals, eMBB terminals), the system can apply different transmission path configurations to different segments, thereby improving reliability for critical services without unnecessarily increasing complexity for all terminals.
Solution Approach 2:
The patent applies local quality by configuring multiple transmission paths selectively for specific terminals or terminal groups that have high reliability requirements, rather than uniformly for all terminals. The base station determines whether to configure multiple paths based on individual terminal characteristics, QoS parameters, and service types, thus improving reliability where needed while controlling overall system complexity.
2Reliability
If multiple transmission paths are configured for all terminals, then communication reliability is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent implements dynamic configuration of transmission paths where the base station determines for each terminal whether to configure one or multiple transmission paths based on real-time conditions including QoS requirements, service types, and terminal characteristics. This dynamic approach ensures that multiple paths are activated only when necessary for reliability, thereby optimizing resource utilization efficiency while maintaining communication reliability where needed.
Solution Approach 2:
The patent changes the parameter of transmission path quantity from a fixed value to a variable that adapts to different terminal requirements. By adjusting the number of transmission paths (one or multiple) based on QoS parameters, service types, and terminal groups, the system achieves both improved reliability for critical services and optimized resource utilization for less critical services.
3Adaptability or versatility
If transmission paths are determined based on QoS and path state information, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the base station autonomously determines transmission path configurations by evaluating QoS information, path state information, and terminal characteristics without requiring complex external control or manual configuration. The base station's determination unit automatically makes decisions about whether to configure multiple transmission paths based on the collected information, thereby improving adaptability while keeping the system relatively simple.
Solution Approach 2:
The patent incorporates feedback mechanisms where the base station continuously monitors QoS information and path state information, and uses this feedback to dynamically adjust transmission path configurations. The determination of whether to configure multiple paths is based on feedback from the network state and terminal performance, enabling adaptability without requiring overly complex predetermined rules.

AI summary
A method and a base station for determining transmission paths are provided. The method includes determining that multiple transmission paths are to be configured for each of one or more terminals, and determining first configuration information of a terminal group corresponding to each terminal, which is used for configuring multiple transmission paths for a terminal in the terminal group. The disclosure reduces the complexity and computation amount of configuring transmission paths and improves the system performance.
