Multi-Link Wireless Transmission with Adaptive Back-Off Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Challenges exist in achieving high data throughput in multi-link wireless communication, particularly in noisy environments, due to interference between links.
Innovation Solution
A method and apparatus that adaptively determine whether to transmit data over a single link or multiple links based on link states, selecting a transmission method that optimizes throughput by delaying transmission until back-off counts of interfering links become zero.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission is performed over multiple links simultaneously to achieve higher throughput, then transmission speed is improved, but interference between links increases
Solution Approach 1:
The patent applies preliminary action by checking the back-off count of other links before transmitting data. The device determines whether to transmit immediately or delay until interfering links have finished their back-off period, preventing interference before it occurs
Solution Approach 2:
The patent uses feedback from the back-off count mechanism to control transmission timing. By monitoring the back-off counts of multiple links and adjusting transmission decisions accordingly, the system dynamically adapts to avoid interference while maximizing throughput opportunities
2Object-affected harmful factors
If transmission is delayed until back-off counts of interfering links become zero to reduce interference, then interference is reduced, but transmission time is increased
Solution Approach 1:
The patent applies dynamics by making the transmission decision adaptive rather than fixed. The device dynamically determines whether to transmit immediately or delay based on the current back-off counts of other links, optimizing the balance between interference avoidance and transmission timing
Solution Approach 2:
The patent changes the transmission timing parameter based on the back-off count values. By adjusting the transmission decision parameter (immediate vs. delayed) according to the back-off count states of interfering links, the system optimizes both interference reduction and time efficiency

AI summary
A wireless communication method performed by a first apparatus may include obtaining back-off counts of a plurality of links, when a back-off count of a first link among the plurality of links is zero, selecting a first or a second transmission method; when the first transmission method is selected, transmitting first data to a second apparatus over the first link, and when the second transmission method is selected, delaying transmission of the first data to the second apparatus until a back-off count of a second link among the plurality of links becomes zero.
