Solution Overview

Problem

The challenge of implementing base station components for wireless network infrastructure sharing among multiple communication service operators is exacerbated by the increased size and cost of frequency bandwidth requirements, leading to higher power consumption.

Innovation Solution

A base station configuration that reduces the frequency bandwidth operated by each processing unit to match that of a single operator, using a switch matrix and phase-locked loops to dynamically adjust the frequency band for each slot, facilitating component implementation and reducing costs and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the base station operates multiple frequency bands to support multiple communication service operators, then the network sharing capability is improved, but the frequency bandwidth requirement increases leading to higher power consumption and implementation difficulty

Engineering Contradiction:

Improvenetwork sharing capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements dynamic frequency band switching where the base station can change the operating frequency band of processing units between time slots. This allows the same hardware to serve multiple operators by dynamically adjusting to different frequency requirements, rather than requiring static support for all frequencies simultaneously, thereby reducing power consumption and implementation complexity.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If the base station operates multiple frequency bands to support multiple communication service operators, then the network sharing capability is improved, but the device complexity and implementation difficulty increase

Engineering Contradiction:

Improvenetwork sharing capabilityVSAvoidimplementation difficulty

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base station uses dynamic configuration of processing units that can be reprogrammed or reconfigured between time slots to handle different frequency bands. This dynamic approach replaces the need for multiple static processing units, simplifying the overall device architecture while maintaining the ability to support multiple operators.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent creates universal processing units that can perform multiple functions by operating at different frequency bands at different times. These processing units are designed to be multi-functional, capable of serving any operator's frequency requirements through software or configuration changes, rather than requiring dedicated hardware for each frequency band.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the base station operates multiple frequency bands to support multiple communication service operators, then the network sharing capability is improved, but the cost increases

Engineering Contradiction:

Improvenetwork sharing capabilityVSAvoidimplementation cost

Core Design Contradiction:

Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

By implementing dynamic frequency switching, the base station requires only one set of processing units that can be reconfigured over time, rather than purchasing and installing multiple sets of processing units for each frequency band. This significantly reduces hardware costs while maintaining the ability to support multiple operators.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent employs universal processing units with multi-functional capabilities that can be configured for different operators through software or control mechanisms. This eliminates the need for expensive dedicated hardware for each operator, reducing manufacturing and deployment costs while enabling network sharing.

Inventive Principle:

Principle #6Universality (Multi-functionality)
