Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective solutions for multi-link operation (MLO) control, particularly when non-collocated access points (APs) are involved, leading to performance malfunctions due to incorrect control.
Innovation Solution
A method for performing cooperation group (CG) indication in a wireless communication system, where non-AP devices compare CG indicators from multiple APs to configure feature support capabilities, enabling or disabling features based on group affiliation, thereby enhancing overall performance and preventing malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If non-AP devices connect to multiple non-collocated APs without CG indication, then multi-link operation diversity is increased, but control accuracy deteriorates leading to performance malfunctions
Solution Approach 1:
The system segments the multi-AP network into distinct cooperation groups identified by unique CG indicators. Each AP is assigned to a specific CG, allowing the non-AP device to segment its connections and apply appropriate control policies based on the CG indicator matching between linked APs.
Solution Approach 2:
The CG indicator acts as an intermediary parameter that mediates the control relationship between non-AP devices and multiple APs. By comparing CG indicators, the system determines whether APs belong to the same cooperation group, enabling accurate control decisions without requiring complex direct AP-to-AP coordination.
2Measurement precision
If CG indication is implemented to improve control accuracy, then system complexity increases due to additional indicator management
Solution Approach 1:
The CG indicator serves multiple functions simultaneously: it identifies cooperation groups, enables control accuracy determination, and provides a basis for feature support capability configuration. This multi-functionality reduces the need for separate control mechanisms, thereby limiting the increase in system complexity.
Solution Approach 2:
The system introduces the CG indicator as a new parameter that changes based on AP group affiliation. By managing control decisions through this single parameter change rather than multiple complex coordination parameters, the system achieves improved control accuracy with minimal complexity overhead.
3Adaptability or versatility
If feature support capabilities are enabled for all connected APs, then service versatility is improved, but system reliability decreases due to incorrect feature support in non-CG scenarios
Solution Approach 1:
The feature support capability configuration is made dynamic based on CG indicator comparison results. The non-AP device continuously monitors CG indicators of connected APs and adjusts feature support capabilities accordingly, enabling features only when APs belong to the same CG, thus maintaining both versatility and reliability.
Solution Approach 2:
The system implements feedback by comparing CG indicators and using the comparison result to determine feature support capability configuration. This feedback mechanism ensures that features are only enabled when the control conditions are met, preventing incorrect feature support while maintaining service versatility when conditions are satisfied.

AI summary
A method for performing cooperation group (CG) indication in a wireless communication system for multi-link operation (MLO) control and associated apparatus one or more AP devices and one or more non-access-point (non-AP) devices are provided. For example, the wireless communication system may include a non-access-point (non-AP) device and at least one other device such as a first access point (AP) and a second AP, and the non-AP device may be wirelessly linking to the first AP and to the second AP. The method may include: comparing a first CG indicator from the first AP with a second CG indicator from the second AP; and configuring a feature support capability of the non-AP device according to a comparison result of the first CG indicator and the second CG indicator.
