Solution Overview

Problem

Current wireless communication systems lack mechanisms for non-AP stations to request resources, such as transmission opportunities (TXOP), for peer-to-peer (P2P) communications, which hinders efficient handling of unmanaged traffic and prioritization of low-latency applications.

Innovation Solution

The implementation of a P2P Resource Solicitation frame allows non-AP stations to request TXOP from an access point (AP) for P2P communications, enabling the AP to allocate necessary resources and facilitate seamless P2P transmissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If non-AP stations cannot request resources from AP, then the system maintains simple resource allocation, but P2P communication efficiency deteriorates and latency-sensitive applications cannot be prioritized

Engineering Contradiction:
ImproveP2P communication efficiencyVSAvoidresource allocation mechanism
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent introduces a resource request mechanism where non-AP stations can request TXOP resources from the AP through structured frame exchanges. The AP acts as an intermediary that receives resource requests, processes them according to network conditions, and allocates TXOP resources accordingly. This resolves the contradiction by enabling efficient P2P communication while maintaining centralized resource management through the AP.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent enables dynamic resource allocation by allowing non-AP stations to request specific TXOP parameters (duration, timing, bandwidth) based on their P2P communication needs. The AP adjusts resource allocation parameters in response to requests, enabling latency-sensitive applications to obtain prioritized resources without fundamentally changing the centralized allocation architecture.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If centralized resource allocation is used, then resource management is simplified, but unmanaged traffic handling and low-latency prioritization deteriorate

Engineering Contradiction:
Improvelow-latency traffic handlingVSAvoidresource management mechanism
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a resource request mechanism where non-AP stations can proactively request TXOP resources in advance before P2P communication begins. This preliminary action allows the AP to allocate resources ahead of time, ensuring that latency-sensitive applications receive prioritized handling without requiring complex real-time resource management changes.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If no resource request mechanism is implemented, then the protocol remains simple, but multi-device connectivity performance deteriorates

Engineering Contradiction:
Improvemulti-device connectivity performanceVSAvoidprotocol structure
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the resource allocation process into distinct phases: resource request phase (non-AP station sends request frame), resource decision phase (AP processes request), and resource allocation phase (AP sends trigger frame with TXOP assignment). This segmentation enables improved multi-device connectivity through structured resource management while maintaining protocol simplicity through clear phase separation and standardized frame formats.

Inventive Principle:
Principle #1Segmentation

AI summary

A station (STA) in a wireless network comprising a memory and a processor coupled to the memory, the processor configured to establish a peer-to-peer (P2P) link with a peer STA; transmit, to an access point (AP), a request frame that requests a resource from the AP to perform P2P communication with the peer STA; receive, from the AP, a trigger frame that allocates a transmission opportunity (TXOP) to the STA; and transmit, to the peer STA, one or more frames via the P2P link within the TXOP.
