Station Channel Resource Allocation for High-Density Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-density wireless network deployments, existing technologies face inefficiencies in managing channel resources, leading to reduced system efficiency and data rate requirements, particularly in scenarios like high-density hotspots and cellular offloading, where many devices compete for the wireless medium.
Innovation Solution
The implementation of High Efficiency Wireless Local Area Network (HEW) and Enhanced Directional Multi Gigabit (EDMG) communication methods, which utilize primary and secondary channel resources, scheduled orthogonal frequency division multiple access (OFDMA) techniques, and directional transmission to optimize channel allocation and data transmission opportunities.

Engineering Contradiction Analysis
1Productivity
If many devices compete for the wireless medium using traditional contention-based access, then device connectivity is maintained, but system efficiency deteriorates in high-density scenarios
Solution Approach 1:
The patent segments the wireless channel into primary and secondary channel resources, allowing different types of traffic and devices to be assigned to different channels. This segmentation enables more efficient resource utilization in high-density scenarios by reducing contention on the primary channel while maintaining device connectivity through secondary channels.
Solution Approach 2:
The patent implements dynamic channel allocation where the access point can assign devices to different channel resources based on current network conditions, device requirements, and traffic patterns. This dynamic assignment allows the system to adapt to changing density conditions and optimize efficiency without requiring complex manual configuration.
2Productivity
If traditional channel allocation methods are used, then implementation simplicity is maintained, but data rate management efficiency deteriorates in high-density deployments
Solution Approach 1:
The patent performs preliminary channel allocation during device association and connection setup, where the access point assigns appropriate primary and secondary channel resources based on predicted device requirements and current network state. This preliminary action reduces the need for complex real-time negotiations and improves data rate management efficiency from the outset.
Solution Approach 2:
The patent implements feedback mechanisms where devices report their channel quality, data rate requirements, and transmission success/failure to the access point. The access point uses this feedback to dynamically adjust channel allocations and optimize data rate management, creating a closed-loop system that improves efficiency without requiring overly complex predetermined configurations.

AI summary
Embodiments of a station (STA) and method for communication on primary and secondary channel resources are generally described herein. The STA may transmit a grant frame to indicate a transmission of a data payload by the STA during a grant period. The grant frame may indicate whether the data payload is to be transmitted on primary channel resources or on secondary channel resources. The STA may transmit the data payload to a destination STA on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources. The grant frame may be transmitted on the primary channel resources and on the secondary channel resources when the grant frame indicates that the data payload is to be transmitted on the secondary channel resources.
