Wireless Channel Allocation Manager for Full-Duplex Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless networks face congestion and communication delays due to the limited wireless spectrum and competition among devices using CSMA/CA protocols, leading to inefficient data transmission rates as more users attempt to access available channels.
Innovation Solution
Implementing a channel allocation manager that schedules wireless channel usage through a TDMA-type protocol, allowing stations to request and allocate channels in specified timeframes, enabling full-duplex communications and channel aggregation, thereby reducing the need for continuous CSMA/CA and minimizing collisions and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If CSMA/CA protocol is used for wireless channel access, then devices can autonomously compete for channels without centralized control, but communication delays and collisions increase as more users access the limited wireless spectrum
Solution Approach 1:
The patent introduces a channel allocation manager as an intermediary component that coordinates channel access between multiple devices. This manager receives channel requests from devices, allocates specific channels for specified timeframes, and manages the overall channel distribution, thereby reducing collisions and delays while maintaining autonomous device operation through the mediation of this central coordinator
Solution Approach 2:
The system performs preliminary channel allocation before actual data transmission occurs. Devices submit channel requests in advance, the channel allocation manager processes these requests and assigns channels for future timeframes, and devices then use the pre-allocated channels for their transmissions, eliminating the need for real-time contention and reducing communication delays
2Adaptability or versatility
If more users compete for limited wireless spectrum using CSMA/CA, then network coverage and user access increase, but data transmission rates decrease due to channel congestion and collisions
Solution Approach 1:
The patent segments the wireless spectrum into multiple channels and further divides channel access into discrete timeframes. By allocating specific channels to specific devices for specific timeframes, the system prevents channel congestion and collisions, allowing multiple users to transmit data simultaneously at high rates without interfering with each other
Solution Approach 2:
The channel allocation system is dynamic and adaptive, allowing the channel allocation manager to reassign channels based on changing network conditions and user demands. This dynamic reallocation optimizes data transmission rates by ensuring that channels are always assigned to devices that need them most, while maintaining the ability to support a growing number of users
3Productivity
If centralized channel allocation is implemented to reduce collisions, then data transmission efficiency improves, but system complexity increases due to the need for channel allocation manager and coordination overhead
Solution Approach 1:
The channel allocation manager is designed as a universal component that can serve multiple devices and channels simultaneously. It handles channel requests from any device, manages all channel allocations across the network, and coordinates transmissions for multiple devices, thereby reducing overall system complexity through consolidation while maintaining high data transmission efficiency

AI summary
A wireless network includes a channel allocation manager and multiple wireless access points. The wireless channel allocation manager receives a request from a first wireless access point amongst multiple wireless access points for allocation of a wireless channel. In response to receiving the request for allocation of a wireless channel, the channel allocation manager selects a particular wireless channel for allocation to the first wireless access point in the network environment. The channel allocation manager notifies the multiple wireless access points of a particular wireless channel that has been allocated for use by the first wireless access point (or its subordinates) in a specified timeframe. The first wireless access point either uses the allocated channel to communicate data downstream to a respective mobile communication device or notifies the mobile communication device that the particular wireless channel has been allocated to communicate upstream to the first wireless access point.
