Solution Overview

Problem

Current communication systems face challenges in efficiently managing resource allocation for device-to-device communications within cells, particularly in allocating and utilizing frequency resources without modifying legacy infrastructure, which can lead to inefficiencies and limitations in direct device-to-device communication.

Innovation Solution

The method involves a communication system where a first communication device receives identification information and resource allocation messages from a server and base station, allowing it to capture signals based on allocated resources, and a frequency master allocator device uses a wired connection to the base station to allocate and manage resources, making them available for direct device-to-device communication without interfering with wireless communications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If base stations allocate resources for traditional wireless communication, then communication reliability is improved, but resource utilization efficiency deteriorates

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidresource utilization efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent segments frequency resources into two distinct parts: one part reserved for traditional wireless communication through base stations, and another part allocated for direct device-to-device communication. This segmentation allows both traditional communication reliability and new resource utilization efficiency to coexist without interference.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent enables communication devices to autonomously capture and utilize allocated frequency resources for direct device-to-device communication without requiring base station intervention or modification. Devices self-organize and self-manage the captured resources, improving overall system efficiency while maintaining traditional communication pathways.

Inventive Principle:

Principle #25Self-service

2Adaptability or versatility

If legacy infrastructure is modified to support device-to-device communication, then adaptability is improved, but device complexity deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent extracts the device-to-device communication functionality from the base station infrastructure and implements it directly at the communication devices. By taking out the need for legacy infrastructure modification and implementing D2C capabilities endpoint-to-endpoint, the system achieves adaptability without increasing base station or network complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

Instead of modifying the base station infrastructure to enable device-to-device communication (traditional approach), the patent inverts the approach by enabling devices to directly capture and use resources without base station mediation. This inversion eliminates the need for legacy system modifications while achieving the same adaptability goal.

Inventive Principle:

Principle #13The other way round (Inversion)

3Measurement precision

If base stations manage all frequency resources, then measurement precision is improved, but loss of time deteriorates

Engineering Contradiction:

Improveresource allocation precisionVSAvoidresource allocation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent implements preliminary resource allocation where base stations pre-allocate frequency resources and communicate allocation information to devices in advance. Devices then capture these pre-assigned resources directly without requiring real-time base station coordination, reducing allocation time while maintaining precision through advance planning.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary mechanism where allocation information is transmitted through available communication channels (such as over-the-air signaling or pre-configured information) rather than requiring direct real-time base station control for each resource capture event. This intermediary approach reduces time delays while preserving allocation precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

Method and system for capturing signals in accordance with allocated resources. One method includes receiving, from a server by a network interface of a first communication device located in a cell, identification information of a second communication device located in the cell. The method further includes receiving, from a base station by the network interface of the first communication device, a resource allocation message destined for the second communication device. The resource allocation message indicates a resource allocation for the second communication device on an uplink channel of the base station. The method further includes decoding, by an electronic processor of the first communication device, the resource allocation message using the identification information of the second communication device. The method further includes capturing, by the network interface of the first communication device, signals based on the resource allocation for the second communication device.
