Simultaneous Wireless Transmissions via Interference Margin Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-density wireless communication environments, the increasing number of devices leads to reduced transmission opportunities due to increased network traffic and interference, resulting in lower network throughput as devices must sense the environment to avoid collisions and interference before transmitting.
Innovation Solution
The solution involves determining an interference margin for a transmission, allowing other devices to transmit simultaneously by announcing this margin, which enables overlapping transmissions without decreasing the data rate of existing transmissions, thereby increasing network throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices sense the environment to avoid collision and interference before transmitting, then transmission reliability is improved, but transmission opportunities are reduced
Solution Approach 1:
The system performs preliminary sensing and determines interference margins before transmissions occur. Devices calculate and announce interference margins in advance, allowing other devices to plan their transmissions accordingly, rather than reacting to interference after it occurs. This preliminary action enables more efficient channel access while maintaining reliability.
Solution Approach 2:
The system changes the parameter of interference tolerance by introducing interference margin values. Instead of using a fixed threshold for detecting interference, devices dynamically adjust their interference tolerance parameters based on calculated margins, allowing simultaneous transmissions that would otherwise be blocked by traditional sensing mechanisms.
2Quantity of substance
If the number of wireless communication devices within an area is increased, then network coverage and connectivity are improved, but network traffic and interference increase
Solution Approach 1:
The system applies local quality by allowing different interference tolerance levels for different transmission pairs. Each device calculates and announces its specific interference margin based on local conditions, enabling transmissions to proceed in regions where interference is acceptable while preventing it in sensitive areas. This localized approach allows high device density without proportional increase in harmful interference.
3Reliability
If traditional sensing mechanisms are used to avoid interference, then transmission quality is maintained, but network throughput decreases
Solution Approach 1:
The system implements feedback by having devices announce their interference margins to the network. This feedback mechanism allows other devices to adjust their transmissions accordingly, enabling simultaneous transmissions that maintain quality for all parties. The feedback loop replaces traditional conservative sensing with informed concurrent access, increasing throughput while preserving transmission quality.

AI summary
Some demonstrative embodiments include apparatuses, systems and/or methods of simultaneous wireless transmissions. For example, an apparatus may include a first wireless communication device to receive an interference margin of a first transmission, the first transmission being from a second wireless communication device to a third wireless communication device, and, based on the interference margin, to transmit a second transmission at least partially overlapping the first transmission.
