Millimeter Wave Resource Allocation for Multi-Protocol Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face interference issues in shared unlicensed frequency spectrums, such as the 2.4 GHz and V-band, due to the lack of effective resource allocation and coordination between devices operating with different protocols, leading to reduced communication efficiency and increased interference.
Innovation Solution
A control device that allocates resources in a millimeter wave environment by dividing the frequency spectrum or time slots between groups of communication devices using different protocols, such as WiHD and NGMS, to minimize interference and optimize resource usage based on usage data from each group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication devices operate in shared unlicensed frequency spectrums using different protocols, then communication versatility is improved, but interference between devices increases
Solution Approach 1:
The control device segments the shared unlicensed frequency spectrum into distinct resource allocations for different protocol groups. It divides frequency bands, time slots, or spatial resources among WiHD devices, NGMS devices, and other protocols, allowing each group to operate in its allocated segment without interfering with others, thus maintaining versatility while eliminating interference.
Solution Approach 2:
The control device acts as an intermediary between different protocol groups (WiHD, NGMS, etc.). It receives resource allocation requests from various devices, processes them according to protocol-specific requirements, and assigns appropriate frequency bands, time slots, or spatial resources. This intermediary coordination enables multiple protocols to coexist in shared spectrums without direct interference.
2Productivity
If resource allocation is implemented across different protocol groups, then communication efficiency is improved, but system complexity increases
Solution Approach 1:
The control device is designed as a universal system that handles multiple protocol types (WiHD, NGMS, and others) through a single integrated resource allocation mechanism. It maintains protocol-specific configurations and allocation rules for each device type while using a unified control interface and resource management framework, thereby improving efficiency across diverse protocols without proportionally increasing system complexity.
3Object-generated harmful factors
If frequency spectrum is divided between different protocol groups, then interference is reduced, but available resources for each group are limited
Solution Approach 1:
The resource allocation system is dynamic rather than static. The control device continuously monitors resource usage, interference levels, and communication demands across different protocol groups, adjusting frequency band assignments, time slot allocations, and spatial resource distribution in real-time. This dynamic adaptation allows the system to reduce interference while optimizing the quantity of available resources for each group based on current conditions.
Solution Approach 2:
The system changes allocation parameters (frequency bands, time slots, power levels, spatial resources) based on protocol requirements and usage patterns. For example, it may allocate wider frequency bands to WiHD devices during low-interference periods, adjust time slot durations for NGMS devices based on data traffic demands, or modify power levels to balance resource availability with interference mitigation, thereby optimizing both interference reduction and resource quantity.
