Cognitive Pilot Channel Reception for Mobile Radio Devices

Solution Overview

Problem

Current mobile radio communication devices using Cognitive Radio and Software Defined Radio paradigms inefficiently scan all possible frequency bands for available radio communication systems, consuming significant battery power and time, especially as the number of possible permutations increases with dynamic frequency allocations.

Innovation Solution

Integration of a Cognitive Pilot Channel (CPC) or Virtual Cognitive Pilot Channel (V-CPC) reception module in mobile radio communication devices, which allows them to receive context information about available radio communication technologies via a dedicated physical or virtual channel, enabling selective reconfiguration without scanning all possibilities.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the device scans all possible frequency bands to detect available radio communication systems, then the device can find all possible communication options, but the scanning time and battery power consumption increase significantly

Engineering Contradiction:

Improveability to detect available radio communication systemsVSAvoidscanning time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The network side performs preliminary action by broadcasting context information about available radio communication systems, frequency bands, and transmission parameters before the device needs to scan. This pre-prepared information is transmitted via cognitive pilot channels, allowing devices to directly acquire knowledge about available systems without performing exhaustive scans, thereby dramatically reducing scanning time while maintaining complete system detection capability

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

A cognitive pilot channel acts as an intermediary between the network and the device. Instead of the device directly scanning all frequency bands to find available systems, the pilot channel mediates by carrying pre-processed context information from the network to the device, enabling the device to efficiently acquire knowledge about available radio communication systems without direct exhaustive scanning

Inventive Principle:

Principle #24Intermediary (Mediator)

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A cognitive pilot channel acts as an intermediary between the network and the device. Instead of the device directly scanning all frequency bands to find available systems, the pilot channel mediates by carrying pre-processed context information from the network to the device, enabling the device to efficiently acquire knowledge about available radio communication systems without direct exhaustive scanning

Inventive Principle:

Solution Approach 2:

The patent replaces the mechanical scanning approach with an information-theoretic approach. Instead of physically scanning through all possible frequency permutations (mechanical search), the system uses cognitive pilot channels to transmit context information about available configurations (information delivery), substituting a computationally intractable mechanical process with an efficient information transmission mechanism

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
