Wireless Access Point Uplink Resource Scheduling for Small Packet Traffic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless Local Area Network (WLAN) systems face low spectrum utilization and network efficiency due to high signaling scheduling overheads and collisions from frequent small packet uplink traffic, particularly in virtual desktop infrastructure (VDI) applications with high Quality of Service (QoS) requirements.
Innovation Solution
A resource scheduling method where a wireless access point (AP) device periodically or dynamically schedules uplink resources for multiple station devices with frequent small packet traffic, reducing signaling overheads and downlink control channel load by determining and allocating uplink resources based on station device information, load statistics, and QoS requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contention based access mechanism is used in WLAN, then devices can access the network independently, but spectrum utilization and network efficiency deteriorate due to high signaling overheads and collisions
Solution Approach 1:
The AP device autonomously determines uplink resource scheduling information based on collected statistics about station devices, eliminating the need for stations to request resources individually. The system self-adjusts scheduling decisions according to observed traffic patterns and QoS requirements, reducing signaling overhead while maintaining efficient resource allocation
Solution Approach 2:
The AP device collects statistics on station device behavior and traffic patterns, then uses this feedback information to dynamically adjust uplink resource scheduling decisions. This closed-loop approach optimizes spectrum utilization by adapting resource allocation to actual network conditions and QoS requirements
2Reliability
If frequent small packet uplink traffic is scheduled individually, then each station receives dedicated service, but signaling scheduling overheads increase and downlink control channel load increases
Solution Approach 1:
The patent merges multiple individual scheduling decisions into a single batch scheduling operation. The AP device determines uplink resource scheduling information for multiple stations simultaneously based on collected statistics, consolidating what would otherwise require numerous separate signaling exchanges into one comprehensive scheduling decision
Solution Approach 2:
The AP device performs preliminary statistics collection and analysis to pre-determine optimal scheduling decisions. By gathering traffic pattern data and QoS requirements in advance, the system can proactively allocate uplink resources before traffic demands arise, eliminating the need for reactive individual scheduling requests
