Dynamic Spectrum Allocation for IMT and Non-IMT Band Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing demand for wireless data communication is leading to a global spectrum shortage, with licensed spectrum becoming overburdened, resulting in decreased quality of service and potential disruptions, as current methods for optimizing spectrum use are inefficient and lack dynamic management solutions.
Innovation Solution
Implementing a dynamic spectrum allocation (DSA) system that allows primary spectrum holders to temporarily rent underused spectrum to secondary users through a cloud-based brokerage, using computational analytics to manage and optimize spectrum use across networks, incorporating both International Mobile Telecommunication (IMT) and non-IMT bands for efficient resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If exclusive mobile spectrum licenses are allocated to wireless network operators, then service quality and connectivity are guaranteed, but spectrum congestion occurs and available spectrum for additional users is exhausted
Solution Approach 1:
The patent implements dynamic spectrum sharing where spectrum allocation transitions from static exclusive licensing to dynamic multi-access allocation. The system allows spectrum to be dynamically allocated between licensed and unlicensed users based on real-time demand, enabling the same spectrum resources to serve multiple users at different times and conditions, thus increasing overall spectrum availability without compromising service quality through proper coordination mechanisms
Solution Approach 2:
The patent enables spectrum to serve multiple functions and user types simultaneously. The same spectrum resources are made usable by both licensed wireless network operators and unlicensed devices through a unified framework that supports diverse access modes, device types, and service requirements, maximizing the utility of limited spectrum resources
2Productivity
If more spectrum is allocated to support increasing wireless data traffic, then user demand is met, but spectrum shortage worsens and existing licensed spectrum becomes overburdened
Solution Approach 1:
The patent changes the fundamental parameter of spectrum access from exclusive to shared, and from static to dynamic. By introducing flexible allocation mechanisms that adjust spectrum assignment based on traffic demand, user type, and network conditions, the system increases productivity without requiring additional licensed spectrum, effectively making existing spectrum resources expand to meet growing demands
3Reliability
If traditional spectrum management methods are used, then licensed spectrum is protected, but spectrum utilization efficiency is low and underused spectrum cannot be recovered
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors spectrum usage patterns, user demands, and network conditions. This feedback enables dynamic adjustment of spectrum allocation decisions, allowing the system to identify and utilize previously underused spectrum opportunities while maintaining protection for licensed users through coordinated access control and interference management
Solution Approach 2:
The patent enables unlicensed devices and networks to autonomously access and utilize available spectrum resources without requiring traditional licensing procedures. The system allows these users to self-organize and self-manage their spectrum access through distributed coordination mechanisms, thereby recovering and utilizing underused spectrum that would otherwise remain idle while maintaining protection for primary licensed users

AI summary
A system and method are provided to facilitate signaling between base stations controlled by alternate spectrum holders (ASH's) and individual multi-mode devices (MMD's) operating in communication with those base stations to indicate an ability to a global spectrum marketplace of an ability of the base stations and/or the individual MMD's to support communication in both International Mobile Telecommunication (IMT) and non-IMT bands is support of a dynamic spectrum allocation scheme. The disclosed systems and methods may be based on a modification of the 3rd Generation Partnership Protocol (3GPP®) Long Term Evolution (LTE®) standard so that non-IMT licensed spectrum can be included in LTE® or LTE-Advanced® multi-band carrier aggregation.
