Primary Link Selection in IEEE 802.11be Multilink Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multilink communication according to the IEEE 802.11be standard, selecting the most appropriate primary link is crucial for efficient communication due to hardware constraints, such as non-simultaneous transmission and reception operations, which limit data transmission opportunities and throughput.
Innovation Solution
A communication apparatus with a determination unit that selects a primary link based on conditions related to frequency channels and radio wave status, ensuring efficient data transmission by prioritizing links with wider bandwidth and more vacant channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NSTR operation is used to comply with hardware constraints, then transmission and reception operations can be performed sequentially, but data transmission opportunities are limited and throughput is reduced
Solution Approach 1:
The patent dynamically selects the primary link based on real-time radio wave status and frequency channel conditions rather than using a fixed selection method. This dynamic adaptation allows the system to optimize data transmission opportunities within NSTR constraints, improving throughput by choosing the most suitable link at each moment.
Solution Approach 2:
The patent changes the selection parameter from static (fixed primary link) to dynamic (based on radio wave status and frequency channel bandwidth). By evaluating multiple parameters including radio wave status and available bandwidth, the system optimizes the primary link selection to maximize data transmission efficiency under NSTR operation.
2Productivity
If multiple wireless links are established to improve communication rate, then throughput is improved, but complexity of selecting appropriate primary link increases
Solution Approach 1:
The determination unit automatically evaluates and selects the primary link based on predefined conditions (radio wave status, frequency channel bandwidth) without requiring manual intervention or complex external control. The system self-optimizes by autonomously determining the most suitable primary link from multiple available links.
Solution Approach 2:
The patent simplifies the selection process by establishing clear selection criteria based on measurable parameters (radio wave status, frequency channel bandwidth). This parameter-based approach transforms the complex selection problem into a systematic evaluation process that can be efficiently automated.
3Reliability
If predetermined radio frames are transmitted only in primary link, then communication protocol compliance is maintained, but communication efficiency is reduced due to limited transmission opportunities
Solution Approach 1:
The patent dynamically determines which link should serve as the primary link based on real-time conditions, allowing the system to adapt to changing communication needs. This dynamic selection optimizes the timing and selection of links for transmitting predetermined radio frames, reducing delays while maintaining protocol compliance.
Solution Approach 2:
The determination unit continuously monitors radio wave status and frequency channel conditions to make informed decisions about primary link selection. This feedback mechanism ensures that the primary link is always the most suitable for transmitting critical radio frames, minimizing communication delays while maintaining protocol requirements.
