AI Technical Summary
The existing IEEE 802.11 standards face challenges in efficiently utilizing a 10 MHz channel for wireless LAN communication, particularly in vehicle-to-everything (V2X) networks, where higher data throughput and real-time transmission are required, and there is a need to address capacity issues and fairness with adjacent channels.
A multi-random backoff operation is performed across multiple links, extending a 10 MHz channel to a 20 MHz channel, allowing for dynamic channel extension based on payload type and performing transmission through a plurality of links, including a primary and secondary channel, to enhance fairness and reduce transmission delay.
This approach enables efficient frame transmission with reduced delay for real-time data and improved channel utilization, ensuring fairness with adjacent channels, thereby enhancing the performance of wireless LAN systems, especially in vehicle-to-everything networks.
