Solution Overview

Problem

In wireless communication systems, especially in future 5G systems like NR, the stability of beam pair links is compromised due to environmental factors and mobility, leading to deteriorated or failed links, particularly at high frequencies.

Innovation Solution

An electronic device at the base station and terminal device sides, equipped with processing circuitry, monitors the status of uplink signals and adjusts the uplink beam pair links by adjusting the transmitting and receiving beams, with the base station transmitting adjustment messages and receiving feedback from the terminal device to optimize the beam pair links.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of energy

If beam sweeping technology is used to establish beam pair links, then beamforming gain is achieved to compensate for radio signal loss, but the beam pair links become unstable due to environmental factors and mobility

Engineering Contradiction:
Improveradio signal lossVSAvoidbeam pair link stability
Core Design Contradiction:
Loss of energyVSReliability

Solution Approach 1:

The patent implements dynamic beam adjustment mechanisms where the base station continuously monitors uplink signal quality and adjusts beam parameters in real-time. The processing circuitry determines when beam adjustment is needed based on signal status monitoring, transforming the static beam configuration into a dynamic system that adapts to changing environmental conditions and mobility scenarios

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent establishes a feedback loop where the base station monitors uplink signal status, determines beam adjustment needs, sends adjustment messages to the terminal device, and receives feedback on the adjustment results. This closed-loop feedback mechanism enables continuous optimization of beam pair links, allowing the system to respond to signal degradation and maintain link stability

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If the number of antenna ports is increased to hundreds for Massive MIMO system, then beamforming application space is expanded, but the complexity of beam management and link maintenance increases

Engineering Contradiction:
Improvebeamforming application spaceVSAvoidbeam management complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements self-service mechanisms where the terminal device autonomously performs beam adjustments based on instructions from the base station. The processing circuitry at both ends automatically monitors signal status and executes beam parameter adjustments without requiring manual intervention or complex centralized control, reducing the operational complexity of managing large-scale antenna systems

Inventive Principle:
Principle #25Self-service
