Multi-Link Wireless Transceiver Radar Channel Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communications systems face performance reduction when radar systems operate in the same radio frequency band, leading to challenges in channel management, particularly in the 5 GHz band, where existing solutions may introduce side effects or fail to maintain connection and prevent packet loss.
Innovation Solution
A method and apparatus using multi-link operation (MLO) architecture, where a wireless transceiver device communicates through multiple links across different radio frequency bands, allowing channel management information to be transmitted and received efficiently even when radar is detected, by utilizing alternative links and dynamically managing traffic identifiers and links to maintain connection and prevent packet loss in the 5 GHz band.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If radar detection causes channel management information transmission delays, then connection reliability is improved, but packet loss increases
Solution Approach 1:
The patent segments the communication system into multiple independent links operating at different radio frequency bands (e.g., 2.4 GHz and 5 GHz bands). When radar is detected in one band, only that specific link is affected, while other links continue to transmit channel management information successfully, preventing packet loss and maintaining connection reliability.
Solution Approach 2:
The patent uses alternative links as intermediaries to transmit channel management information when the primary link is blocked by radar. The system identifies available alternative links and routes management frames through these intermediary paths, ensuring continuous communication without packet loss even when one link is unavailable.
2Measurement precision
If channel management information is transmitted only when the other device is ready, then transmission accuracy is improved, but response time increases
Solution Approach 1:
The patent implements preliminary action by continuously monitoring device readiness states and proactively transmitting channel management information through alternative links before the primary link becomes unavailable due to radar detection. This ensures timely delivery of management frames without waiting for perfect transmission conditions, reducing response time while maintaining accuracy.
3Device complexity
If single-link operation is used, then device complexity is reduced, but adaptability to radar interference decreases
Solution Approach 1:
The patent implements multi-functionality by enabling the wireless communication system to operate across multiple radio frequency bands simultaneously. Each link serves multiple purposes: normal communication, radar avoidance, and channel management information transmission. This universal approach allows the system to adapt to radar interference by switching between bands without requiring complex dedicated systems for each function.

AI summary
A method for performing channel usage management with aid of multi-link operation architecture and associated apparatus are provided. The method applicable to a wireless transceiver device within a wireless communications system may include: utilizing the wireless transceiver device to communicate with another device within the wireless communications system through at least one portion of multiple links respectively corresponding to multiple predetermined radio frequency bands; and at first time point when radar is detected in a first channel used by a first link among the multiple links, starting performing a first procedure to make channel management information be received by the other device via one or more other links among the multiple links at any time point when the other device is ready to receive the channel management information, wherein the other device is not ready to receive the channel management information at the first time point.
