Solution Overview

Problem

Current wireless communication systems face inefficiencies due to internal IC interconnect limitations, leading to uneven resource utilization and potential interference between devices, particularly in intra-device millimeter wave communications.

Innovation Solution

A method and apparatus for managing frequency use among wireless communication devices, where a controller identifies overlapping coverage areas and negotiates frequency ranges for controlled and non-controlled radiation patterns to minimize interference, using MMW transceivers and ICs to coordinate frequency allocation and communication paths.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If wireless communication devices use internal IC interconnects for communication, then device integration is improved, but resource utilization becomes uneven and interference occurs

Engineering Contradiction:
Improvedevice integrationVSAvoidresource utilization
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent divides the frequency spectrum into multiple segments (first frequency range for controlled radiation pattern communications, second frequency range for non-controlled radiation pattern communications) and allocates them to different ICs based on their specific communication needs. This segmentation allows each IC to operate on designated frequency ranges, preventing interference and improving resource utilization efficiency.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent assigns different frequency characteristics to different ICs based on their local requirements. ICs with controlled radiation pattern requirements are allocated specific frequency ranges, while ICs with non-controlled radiation patterns are allocated other ranges. This local differentiation optimizes resource allocation and eliminates interference between different ICs within the same device.

Inventive Principle:
Principle #3Local quality

2Area of stationary object

If devices operate in overlapping coverage areas, then communication coverage is improved, but interference between devices increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidinterference
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent introduces frequency range allocation as an intermediary mechanism between overlapping devices. By assigning different frequency ranges to different devices operating in overlapping coverage areas, the system acts as a mediator that prevents direct interference while maintaining communication coverage. The controller mediates frequency coordination between devices to resolve overlapping coverage conflicts.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the frequency parameter to resolve interference issues. When devices operate in overlapping coverage areas, the system adjusts and assigns different frequency ranges to each device, transforming the frequency parameter to eliminate interference while preserving the benefit of overlapping coverage for extended communication area.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If frequency ranges are allocated without coordination, then device simplicity is maintained, but interference occurs and resource utilization is inefficient

Engineering Contradiction:
Improvefrequency allocation simplicityVSAvoidinterference avoidance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent implements a feedback mechanism where the controller receives information about other devices' frequency usage and coverage areas, processes this feedback, and adjusts frequency range allocations accordingly. This feedback loop enables coordinated frequency allocation that prevents interference while maintaining relatively simple device architecture, as the coordination is handled by the controller rather than requiring complex changes to individual ICs.

Inventive Principle:
Principle #23Feedback

AI summary

An integrated circuit (IC) includes a plurality of circuit modules, a millimeter wave (MMW) transceiver coupled to a configurable antenna structure, and a controller. The controller is operably coupled to: receive parameters for an inter-chip MMW communication link; interpret the parameters to determine a range of operational requirements; compare the range of operational requirements with configuration options of the MMW transceiver and the configurable antenna structure; and, when one of the configuration options compares favorably with the range of operational requirements, generate a configuration signal to instruct the MMW transceiver and the configurable antenna structure to implement the one of the configuration options.
