Solution Overview

Problem

Current wireless telecommunications network deployments face issues with intra-cell interference and network performance due to non-maximally spaced TR components and high Sector Power Ratios (SPR), leading to suboptimal beamforming settings that do not account for SPR or azimuthal settings, resulting in reduced network performance for UEs.

Innovation Solution

Dynamic beamforming settings are adjusted based on the Sector Power Ratio (SPR) of TR components within a broadcast cell, modifying the power and/or phase to broaden or taper the network signal footprint, thereby reducing intra-cell interference and improving network performance by optimizing the SPR values.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If TR components are not maximally spaced apart, then device complexity is reduced, but intra-cell interference increases and network performance deteriorates

Engineering Contradiction:
ImproveTR component spacing configurationVSAvoidnetwork performance
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent applies dynamics by making beamforming settings adjustable and adaptive rather than fixed. The system dynamically modifies beamforming parameters based on TR component azimuthal positions and SPR values, allowing the network to optimize performance despite non-maximal spacing. This resolves the contradiction by enabling flexible adaptation to various TR component configurations without requiring maximal spacing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes physical or operational parameters (beamforming weights, power levels, phase shifts) to optimize network performance. By adjusting these parameters based on measured SPR values and azimuthal positions, the system compensates for suboptimal TR component spacing, resolving the contradiction between simplified configuration and maintained performance.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If beamforming settings do not account for SPR, then ease of operation is improved, but network performance deteriorates

Engineering Contradiction:
Improvebeamforming configurationVSAvoidnetwork performance
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system performs self-service by automatically measuring SPR values and adjusting beamforming settings without manual intervention. The network autonomously optimizes its performance by monitoring signal characteristics and adapting beamforming parameters, eliminating the need for complex manual configuration while maintaining optimal network performance.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent implements feedback mechanisms where the system continuously monitors network signal characteristics, measures SPR values, and uses this information to adjust beamforming settings. This closed-loop approach enables automatic optimization of network performance while keeping the system easy to operate, resolving the contradiction between operational simplicity and performance optimization.

Inventive Principle:
Principle #23Feedback

3Manufacturing precision

If sector power ratio is not optimized, then manufacturing precision requirements are reduced, but intra-cell interference increases

Engineering Contradiction:

Core Design Contradiction:

Solution Approach 1:

The patent changes operational parameters (beamforming weights, power levels) to compensate for TR component positioning variations. By dynamically adjusting these parameters based on measured azimuthal positions and SPR values, the system reduces intra-cell interference without requiring high manufacturing precision in TR component placement.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent replaces mechanical positioning precision requirements with electronic parameter adjustment. Instead of relying on precise physical spacing of TR components, the system uses electronic beamforming control to achieve optimal signal distribution, substituting mechanical precision with electronic flexibility to reduce intra-cell interference.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
