Wireless Channel Allocation via Aggregated Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for allocating wireless channels in the 3.5 GHz band require an Environmental Sensing Capability (ESC) to detect incumbents, which is costly and compromises incumbent privacy, while individual devices cannot reliably determine the presence of incumbents, leading to inefficient spectrum sharing.
Innovation Solution
A method and apparatus that aggregate energy level measurements from multiple sensing devices to reliably determine the presence of incumbents without an ESC, using commercially available devices to perform measurements and ensure compliance with regulatory requirements, allowing for efficient channel allocation to Tier 2 and Tier 3 users when incumbents are not detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Environmental Sensing Capability (ESC) is used to detect incumbents, then incumbent detection reliability is improved, but system cost and complexity increase
Solution Approach 1:
The patent combines sensing capabilities from multiple independent devices into a centralized detection system. Individual devices perform local energy measurements and report results to a controller, which aggregates data to determine incumbent presence. This merging approach achieves reliable detection without requiring each device to have full ESC functionality, reducing individual device complexity while maintaining system-level reliability.
2Measurement precision
If ESC is deployed for incumbent detection, then detection accuracy is improved, but incumbent privacy is compromised
Solution Approach 1:
The patent introduces a centralized controller as an intermediary between sensing devices and incumbent operations. The controller receives aggregated energy measurement data from multiple devices and performs incumbent detection analysis centrally. This intermediary architecture allows accurate detection through data aggregation while protecting privacy by processing only aggregated statistical information rather than individual device data or detailed incumbent operational information.
3Ease of operation
If individual devices perform incumbent detection, then device autonomy is improved, but detection reliability deteriorates
Solution Approach 1:
The patent segments the detection function into two parts: local energy measurement performed autonomously by individual devices, and centralized analysis performed by a controller. Each device independently performs measurements and reports results, maintaining device autonomy for the sensing function. The controller then aggregates these segmented measurements from multiple devices to perform reliable incumbent detection, achieving both autonomy and reliability through functional segmentation.
4Productivity
If spectrum sharing is enabled without reliable incumbent detection, then spectrum utilization is improved, but interference risk increases
Solution Approach 1:
The patent implements a feedback mechanism where sensing devices continuously monitor energy levels and report measurements to a centralized controller. The controller uses this feedback data to dynamically determine incumbent presence and adjust spectrum allocation decisions accordingly. This feedback loop enables safe spectrum sharing by providing continuous monitoring and real-time detection information, allowing spectrum utilization to be maximized while maintaining interference protection through ongoing verification.

AI summary
An apparatus and a method for allocating wireless channels are disclosed. For example, the method, by an aggregator, aggregates sensed information received from a plurality of sensing devices, by an analyzer, analyzes the sensed information that is aggregated and determines when an incumbent is not detected based on the analysis, and allocates, by a channel allocator, a wireless channel of the targeted frequency spectrum to a user equipment when the incumbent is not detected.
