Multi-Link Medium Synchronization During Active Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices operating in non-STA mode or EMLSR mode face challenges in receiving medium synchronization information for links other than the one being used for data transmission, leading to increased latency and reduced data transmission efficiency.
Innovation Solution
The electronic device receives medium synchronization information through one link while transmitting data through another link, allowing it to maintain synchronization and perform data transmission rapidly across multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the electronic device operates in non-STA mode or EMLSR mode to transmit data through one link, then data transmission can occur through that link, but the device is unable to receive data through another link simultaneously, causing failure to receive medium synchronization information for the other link
Solution Approach 1:
The patent segments the information transmission by separating medium synchronization information from regular data frames. The synchronization information is embedded within data frames transmitted on the first link, allowing the receiving device to extract and process synchronization information for the second link even while the first link is actively transmitting data. This segmentation enables simultaneous data transmission and synchronization maintenance across multiple links.
Solution Approach 2:
The patent uses the first link as an intermediary channel to convey medium synchronization information about the second link. By embedding synchronization information within data frames transmitted on the first link, the system creates a mediator mechanism that allows the receiving device to stay synchronized with the second link without needing to actively receive dedicated synchronization signals on that link.
2Reliability
If the electronic device waits for data to be received through a specific link or waits until a specified time to perform data transmission, then medium synchronization can be maintained, but latency of data transmission increases
Solution Approach 1:
The patent applies preliminary action by maintaining medium synchronization information in advance through continuous reception via the first link. The receiving device proactively updates its synchronization state using information embedded in data frames before actual data transmission on the second link is needed, eliminating the need to wait for timeout periods or dedicated synchronization signals.
Solution Approach 2:
The patent ensures continuity of useful action by making the reception of medium synchronization information an ongoing process through the first link. Instead of periodic or event-driven synchronization updates, the device continuously extracts synchronization information from incoming data frames, maintaining up-to-date synchronization state without interruption or delay.
3Measurement precision
If the electronic device performs medium synchronization based on data received through a specific link, then synchronization accuracy is improved, but the device must be in a state of receiving data through that link, limiting operational flexibility
Solution Approach 1:
The patent applies universality by making the first link serve multiple functions: it is used both for regular data transmission and for conveying medium synchronization information about the second link. This multi-functionality allows the receiving device to maintain synchronization accuracy while preserving operational flexibility, as the same link performs dual roles without requiring separate dedicated synchronization channels.
