Multi-Link Wireless RTS Coordination to Reduce Non-STR Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems using multiple links face challenges in maintaining data reliability due to interference between links, particularly in non-Simultaneous Transmit And Receive (non-STR) link pairs, which affects the smooth performance of protection mechanisms and overall communication reliability.
Innovation Solution
The proposed solution involves a wireless communication device with a radio frequency integrated circuit (RFIC) and processor that adaptively control the transmission timing and content of frames, such as Request To Send (RTS) frames, to align and synchronize communications across multiple links, thereby minimizing interference and enhancing data reliability.

Engineering Contradiction Analysis
1Productivity
If multiple links are used for wireless communication, then data transmission capacity and speed are improved, but interference between links occurs which deteriorates data reliability
Solution Approach 1:
The device obtains transmission-related information of RTS frames on other links before transmitting RTS frames on the current link. This preliminary action allows the device to determine transmission timing and content of RTS frames in advance, avoiding interference with other links and ensuring reliable data transmission across multiple links simultaneously
Solution Approach 2:
The device uses transmission-related information obtained from other links to adjust and determine the transmission timing and content of RTS frames. This feedback mechanism ensures that transmissions on multiple links are coordinated, preventing interference while maintaining high data transmission capacity
2Productivity
If RTS frames are transmitted simultaneously on multiple links, then communication efficiency is improved, but interference between links deteriorates protection mechanism performance
Solution Approach 1:
The device performs preliminary determination of RTS frame transmission timing by obtaining transmission-related information from other links before actual transmission. This ensures that RTS frames are transmitted at coordinated times that avoid interference, maintaining both communication efficiency and protection mechanism performance
Solution Approach 2:
The device dynamically determines the transmission timing and content of RTS frames based on real-time transmission-related information obtained from other links. This dynamic adjustment allows the system to adapt to changing channel conditions while preventing interference and maintaining protection mechanism effectiveness

AI summary
A wireless communication method performed by a first device includes entering a transmission preparation period of a first Request To Send (RTS) frame via a first link; obtaining transmission-related information of a second RTS frame via a second link; determining at least one of a first transmission timing and content of the first RTS frame, based on the transmission-related information of the second RTS frame; generating the first RTS frame based on a result of the determining; and transmitting, to a second device via the first link, the generated first RTS frame.
