Solution Overview

Problem

Current communication systems face challenges in effectively managing wireless communications in dense deployments, where numerous devices operate within a limited area, leading to inefficiencies and difficulties in coordinating data transmission and association.

Innovation Solution

The implementation of a resource and association poll frame (ra-poll frame) mechanism that specifies parameters for eligibility to transmit, subsets of sub-carriers, and authorized frame formats, allowing wireless communication devices to determine their eligibility and schedule transmissions efficiently, even in dense environments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional wireless communication protocols are used in dense deployments, then device connectivity is maintained, but transmission coordination efficiency deteriorates due to interference and collision from numerous devices operating in limited area

Engineering Contradiction:
Improvetransmission coordination efficiencyVSAvoidinterference and collision from numerous devices
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the wireless communication process into distinct phases: polling phase where the AP queries stations, and response phase where authorized stations transmit. This segmentation prevents random access collisions by ensuring only authorized stations transmit during their designated response windows, thereby resolving the interference problem in dense deployments

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The access point performs preliminary actions by sending poll frames that pre-authorize specific stations before they transmit data. This preliminary authorization mechanism prevents collision by ensuring only pre-cleared stations can access the medium, improving transmission coordination efficiency in dense environments

Inventive Principle:
Principle #10Preliminary action

2Productivity

If polling mechanisms are implemented to improve transmission coordination, then spatial reuse and performance in dense deployments are enhanced, but device complexity increases due to additional frame structures and protocols

Engineering Contradiction:
Improvespatial reuse and performance in dense deploymentsVSAvoidframe structures and protocols
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The poll frame structure is designed to be universal, serving multiple functions: it acts as a trigger for station responses, carries authorization information, and establishes transmission parameters. This multi-functionality reduces the need for separate control frames, thereby limiting the increase in device complexity while maintaining improved spatial reuse performance

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If resource and association poll frames are used to specify transmission eligibility parameters, then transmission scheduling efficiency is improved, but loss of information increases due to additional parameter specification requirements

Engineering Contradiction:
Improvetransmission scheduling efficiencyVSAvoidparameter specification overhead
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent merges resource allocation parameters and association information into a single poll frame structure. By combining multiple information elements (transmission eligibility, subcarrier subsets, frame format authorizations) into one unified frame, the system improves scheduling efficiency while minimizing information loss through consolidated parameter specification

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A wireless communication device (alternatively, device) includes a processor configured to support communications with other wireless communication device(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processor, among other possible circuitries, components, elements, etc. to support communications with other device(s) and to generate and process signals for such communications. A device generates and transmits a resource and association poll frame (ra-poll frame) to other device(s). The contents of ra-poll frame direct which of the other device(s) is authorized to respond to the device (e.g., authorized device(s)) and the manner in which they are authorized to respond. Authorized device(s) transmit responses that may include association request(s) and/or a resource request(s), among other types of communications. The device then generates and transmits acknowledgement(s) (ACK(s)) indicates successful receipt of any responses from the authorized device(s).
