Wireless Frame Termination Signaling for Priority Channel Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, once a device begins transmitting a data frame, the channel remains unavailable for other frames until the current frame is completed, which can hinder the transmission of higher priority, time-sensitive data.
Innovation Solution
Implementing a termination signal to indicate premature termination of a lower priority data frame, allowing the channel to be freed up for higher priority data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device begins transmitting a data frame over a wireless channel, then the transmission reliability of the current frame is improved, but the channel becomes unavailable for other frames until transmission is complete, reducing overall network productivity
Solution Approach 1:
The patent applies preliminary action by sending a termination signal before the actual transmission of the data frame is complete. This allows the receiving device to prepare for channel reuse in advance, freeing up the wireless channel sooner for higher priority transmissions and improving overall network productivity while maintaining reliable communication through proper protocol handling
2Reliability
If the wireless channel is kept occupied until frame transmission is complete, then data integrity is ensured, but time-sensitive higher priority data cannot be transmitted, increasing loss of time
Solution Approach 1:
The termination signal enables preliminary action by notifying the receiving device in advance that the current frame transmission will be interrupted. This allows the receiver to prepare for channel reuse before the transmission actually ends, reducing the time the channel remains occupied and enabling faster transmission of time-sensitive high priority data while maintaining data integrity through proper acknowledgment handling
3Productivity
If transmission of a data frame is terminated early to free the channel, then productivity is improved, but the receiving device may not know transmission is complete, increasing device complexity for error handling
Solution Approach 1:
The patent applies feedback by implementing a termination signal that provides explicit notification to the receiving device about early transmission termination. This feedback mechanism allows the receiver to distinguish between intentional early termination and transmission errors, reducing device complexity for error handling while improving channel availability for higher priority transmissions

AI summary
Example operations may include initiating wireless transmission of a first data frame of data designated for wireless transmission. The wireless transmission of the first data frame may be via a first wireless signal packet configured to carry the data of the first data frame. The operations include directing termination of the wireless transmission of the first data frame via the first wireless signal packet prior to wireless transmission, via the first wireless signal packet, of all of the data of the first data frame. In addition, the operations include directing, in response to termination of transmission of the first data frame, wireless transmission of a termination signal, the termination signal indicating that transmission of the first data frame via the first wireless signal packet terminated prior to completion of transmission of all of the data of the first data frame via the first wireless signal packet.
