QoS Phase Encoding for Wireless Transmission Priority
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, there is a need for methods to facilitate the communication and use of quality of service (QoS) level information in peer-to-peer networks to enable devices to make informed decisions about data transmission, particularly in scenarios where interference and priority levels are involved.
Innovation Solution
The method involves recovering QoS levels from transmission request response signals, using the phase of these signals to convey priority information, and making decisions on whether to transmit based on the recovered QoS levels, interference costs, and predetermined thresholds, allowing devices to yield to higher priority traffic to avoid interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If devices transmit data without considering QoS levels, then transmission simplicity is maintained, but interference and priority management deteriorate
Solution Approach 1:
The system implements feedback mechanisms where devices receive QoS level information from transmission request response signals and use this feedback to make informed transmission decisions. This allows devices to adjust their behavior based on priority information without requiring complex manual intervention, resolving the contradiction between operational simplicity and effective interference management.
Solution Approach 2:
The patent changes the parameter space by encoding QoS levels as phase information in transmission request response signals. This allows priority information to be conveyed without adding significant complexity to the transmission protocol, enabling devices to manage interference through parameter-based decisions rather than complex control mechanisms.
2Reliability
If devices implement QoS-based transmission decisions, then priority management improves, but decision-making complexity increases
Solution Approach 1:
The patent introduces QoS level information as an intermediary element that mediates between transmission decisions and priority requirements. By encoding priority information in the phase of transmission request response signals, the system provides a clear intermediary parameter that devices can use to make decisions without needing to process complex priority management logic directly.
Solution Approach 2:
The system performs preliminary action by including QoS level information in transmission request response signals before the actual data transmission occurs. This allows receiving devices to prepare their transmission decisions in advance based on priority information, reducing the complexity of real-time decision-making while ensuring proper priority management.
3Productivity
If devices use phase information for QoS encoding, then signal efficiency improves, but signal interpretation difficulty increases
Solution Approach 1:
The patent applies universality by using the phase of transmission request response signals for multiple purposes: conveying QoS level information while maintaining the existing signal's primary function. This multi-functional approach improves signal efficiency without requiring separate dedicated signals for QoS information, and the phase modulation remains compatible with standard signal detection techniques.

AI summary
Methods and apparatus for making communications decisions are described. In some embodiments, a method includes recovering a quality of service level from a transmission request response signal and making a decision whether or not to transmit traffic data based on the recovered quality of service level. In other embodiments a method includes recovering a first quality of service level from a first transmission request response signal which is in response to a first traffic transmission request signal, and making a decision, based on the recovered first quality of service level, whether or not to transmit a second transmission request response signal in response to a second traffic transmission request signal. In some embodiments, the phase of the transmission request response signal is used to communicate the quality of service level. The device transmitting the transmission request response may also transmit pilots which can be used as phase reference signals.
