Vendor-Specific IE Rate Control for Multi-Band WLAN Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission rate control methods in wireless local area networks (WLANs) based on IEEE 802.11 standards are limited, as they often depend on specific Physical Protocol Data Unit (PPDU) types and are not effective for achieving target data transmission rates across multiple channel bandwidths.
Innovation Solution
A data transmission rate control scheme using vendor-specific information elements and action frames to control the transmission rate of devices, allowing for non-standard communication and rate control capabilities, enabling the device to support various features and modulation schemes without relying on specific PPDU types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional data rate control methods are used, then the control is limited to specific PPDU types, but the effectiveness for achieving target data transmission rates across multiple channel bandwidths deteriorates
Solution Approach 1:
The patent implements a universal rate control mechanism using vendor-specific Information Elements that can control data transmission rates across all PPDU types and multiple channel bandwidths (20 MHz, 40 MHz, 80 MHz, 160 MHz). The vendor-specific IE framework allows a single control structure to handle diverse transmission scenarios that conventional methods could not address effectively
Solution Approach 2:
The patent changes the control parameters by introducing vendor-specific Information Elements with custom rate control fields that can specify target data rates, modulation schemes, and coding rates. This parameter extension allows flexible rate control across different channel bandwidths and PPDU types without being constrained by standardized field limitations
2Adaptability or versatility
If vendor-specific information elements are used, then rate control capability and versatility improve, but compliance with standardized IEEE 802.11 formats may be compromised
Solution Approach 1:
The patent uses vendor-specific Information Elements as an intermediary mechanism that bridges standardized IEEE 802.11 communication and custom rate control requirements. The vendor-specific IE acts as a mediator layer that maintains compatibility with the standardized frame structure while enabling extended functionality through vendor-defined fields, thus preserving standard compliance while achieving enhanced rate control capability
