Proxy QoS Setup for Low-Latency Peer-to-Peer Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle to effectively manage peer-to-peer (P2P) traffic in wireless networks, particularly for latency-sensitive applications like augmented reality and robotics, due to unregulated traffic interfering with low-latency requirements.
Innovation Solution
A mechanism and protocol for proxy quality of service (QoS) setup, where a first station (STA) requests QoS parameters for a second STA's P2P traffic through an access point (AP), allowing the AP to allocate channel resources and manage QoS flows, including setup, removal, or modification of QoS for P2P traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If unregulated traffic is allowed in wireless networks, then network flexibility and ease of operation are improved, but latency for low-latency applications increases and QoS cannot be guaranteed
Solution Approach 1:
The patent introduces an intermediary mechanism where a first STA acts as a proxy to request QoS parameters for a second STA's P2P traffic through the AP. This intermediary approach allows the network to maintain operational flexibility while ensuring QoS requirements are met, as the proxy mechanism enables coordinated resource allocation without restricting network operation.
Solution Approach 2:
The patent implements preliminary action by establishing QoS flows and allocating channel resources before P2P traffic transmission begins. The AP receives QoS setup requests, determines appropriate parameters, and allocates resources in advance, ensuring that latency-sensitive applications receive guaranteed service quality before actual data transmission occurs.
2Productivity
If QoS flows are established for P2P traffic, then latency and throughput are improved, but device complexity and protocol overhead increase
Solution Approach 1:
The patent applies universality by enabling a STA to perform multiple functions: it can act as both a regular data transmitting device and a proxy for requesting QoS parameters for another STA. This multi-functionality reduces the need for separate dedicated QoS management devices, thereby limiting the increase in device complexity while maintaining improved throughput through proper QoS flow establishment.
3Reliability
If the AP manages QoS for all STAs, then QoS guarantee and reliability are improved, but control overhead and network management complexity increase
Solution Approach 1:
The patent implements self-service by enabling STAs to autonomously request QoS parameters for their P2P traffic through the proxy mechanism. Instead of the AP proactively managing all QoS aspects, the STA initiates QoS setup requests when needed, reducing AP management overhead while maintaining QoS guarantees through the structured request-response protocol between STA and AP.
Data Source
AI summary
A first station (STA) in a wireless network, comprising a memory and a processor coupled to the memory. The processor is configured to cause transmitting, to an access point (AP), a request frame that requests for setting up a quality of service (QoS) flow for a second STA's peer to peer (P2P) traffic. The request frame includes one or more QoS parameters associated with the QoS flow and a field indicating a type of request frame. The processor is further configured to cause receiving, from the AP, a response frame in response to the request frame.
