Solution Overview

Problem

Existing wireless communication systems face challenges in optimizing the use of multiple communication links associated with different subscriptions in a user equipment (UE), leading to inefficiencies in data transmission and potential data collisions.

Innovation Solution

A base station determines when multiple communication links from the same UE are established and coordinates their use based on the type of information to be communicated, either using one link or multiple links, to optimize data transmission and avoid collisions.

1Productivity

If multiple communication links are used simultaneously for different subscriptions, then data transmission capacity is improved, but data collisions and interference increase

Engineering Contradiction:
Improvedata transmission capacityVSAvoiddata collision risk
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The base station monitors the status of multiple communication links and adjusts their coordination based on feedback information about link quality, interference levels, and data transmission status. This allows dynamic optimization of link usage to maintain high throughput while avoiding data collisions.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system dynamically coordinates multiple communication links by adjusting transmission parameters, link selection, and resource allocation in real-time based on current network conditions. This dynamic coordination enables the system to adapt to changing conditions and optimize both throughput and reliability.

Inventive Principle:
Principle #15Dynamics

2Productivity

If multiple communication links are coordinated based on information type, then data transmission efficiency is improved, but system complexity increases

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidcoordination system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The coordination mechanism segments the communication process by handling different information types (control plane vs. user plane) through separate coordination rules. This segmentation simplifies the overall coordination complexity while maintaining high transmission efficiency for each information type.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system changes coordination parameters based on information type, applying different coordination strategies for control plane information versus user plane data. This parameter-based differentiation improves transmission efficiency while keeping the coordination system manageable through standardized rules.

Inventive Principle:
Principle #35Parameter changes

AI summary

Aspects relate to coordination of communication links associated with multiple subscriptions. For example, a base station may determine that a first communication link and a second communication link are established with a user equipment (UE) using a first subscription and a second subscription of the UE, respectively. At least one of the first communication link or the second communication link may be established between the UE and the base station. The base station may coordinate communication of information with the UE via at least one of the first communication link or the second communication link based on the determination. The base station may coordinate the communication of information by selecting, based on the information, one of: the first communication link and the second communication link for communicating the information, or the first communication link or the second communication link for communicating the information without utilizing the other communication link.
