Dynamic Spectrum Renting for Wireless Service Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Local operating entities in wireless communication systems, especially those without licensed spectrum, face challenges in providing high-bandwidth services due to congestion in unlicensed spectra, necessitating mechanisms for dynamic spectrum use and coordination with spectrum owners.
Innovation Solution
Implementing mechanisms for local service advertising and discovery, allowing local operators to request temporary spectrum use from spectrum owners based on service demands, with synchronous and asynchronous methods for in-band and out-of-band spectrum usage, respectively, to enhance service quality and coordination.

1Area of stationary object
If local operating entities use unlicensed spectrum for wireless services, then service coverage can be extended, but spectrum congestion increases and service quality deteriorates
Solution Approach 1:
The patent implements dynamic spectrum access where local operators can dynamically request and obtain temporary spectrum rentals from spectrum owners based on real-time service demands. This dynamic mechanism allows the system to adapt spectrum allocation to changing conditions, enabling high-bandwidth services when needed while avoiding persistent congestion in unlicensed bands.
Solution Approach 2:
The patent changes the spectral parameter by allowing operators to switch between unlicensed and licensed spectrum bands. Through spectrum renting, operators can change the frequency band parameter from congested unlicensed bands to available licensed bands, thereby maintaining service quality while preserving coverage area.
2Productivity
If local operators dynamically request spectrum use from spectrum owners, then high-bandwidth services can be provided, but coordination complexity increases
Solution Approach 1:
The patent establishes preliminary agreements and frameworks for spectrum renting before actual service delivery. Spectrum owners and local operators pre-arrange spectrum access terms, pricing, and coordination protocols, which simplifies real-time operations. This preliminary structuring reduces coordination complexity during dynamic spectrum access while enabling high-bandwidth services.
3Productivity
If multiple operators share licensed spectrum through priority-based access, then spectrum utilization improves, but access delays increase for non-primary users
Solution Approach 1:
The patent implements periodic spectrum sharing where primary users and secondary users take turns accessing the spectrum in defined time periods. This periodic structure allows spectrum owners to maintain primary access rights while providing guaranteed time slots to local operators, thereby improving overall utilization without causing unbounded access delays.

AI summary
Wireless communication systems and methods related to service advertising and discovery with dynamic spectrum use are provided. A user equipment (UE) receives, from a first wireless communication device, a network information signal in a spectrum. The UE receives, from a second wireless communication device, a service advertising signal based on at least a synchronization to the network information signal. The service advertising signal indicates an availability of a service. The UE transmits, to the second wireless communication device, a request for the service. The first wireless communication device and the second wireless communication device are associated with different operating entities of the spectrum.
