Solution Overview

Problem

Existing communication methods in 5G systems face challenges in maintaining effective beamlock operations and managing transmitting power in non-connected states, leading to inefficiencies and potential signal interference.

Innovation Solution

A method involving a user equipment (UE) that obtains beamlock-related information in a connected state and performs corresponding operations in a non-connected state, including activating or de-activating beamlocks based on duration, power, and timing information, and a network node that measures and adjusts UE transmitting power and beam directions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If beamlock function is used in connected state, then beam correspondence can be maintained, but it cannot operate in non-connected states (idle or inactive states)

Engineering Contradiction:

Improvebeamlock operation capabilityVSAvoidbeam correspondence maintenance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The network node configures beamlock parameters and sends configuration messages to the UE while in connected state, preparing the beamlock settings in advance. This preliminary configuration enables the UE to maintain beam correspondence when transitioning to non-connected states, as the beamlock parameters are pre-established and can be executed autonomously by the UE without real-time network control.

Inventive Principle:

Principle #10Preliminary action

2Use of energy by moving object

If UE transitions to non-connected state, then power consumption is reduced, but transmitting power becomes unpredictable

Engineering Contradiction:

Improvepower consumptionVSAvoidtransmitting power measurement

Core Design Contradiction:

Use of energy by moving objectVSMeasurement precision

Solution Approach 1:

The network node measures the uplink signal power received from the UE in non-connected state and provides feedback through configuration messages or reconfiguration. This feedback mechanism allows the network to monitor and control the UE's transmitting power even when the UE is in low-power non-connected state, ensuring predictable power levels for beam correspondence testing while maintaining energy efficiency.

Inventive Principle:

Principle #23Feedback

3Reliability

If beamlock parameters are configured for non-connected state, then beam correspondence testing is enabled, but device complexity increases

Engineering Contradiction:

Improvebeam correspondence testingVSAvoidconfiguration management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent uses existing RRC message structures and configuration mechanisms that are already part of the 5G NR standard, making the beamlock configuration for non-connected states utilize existing multi-functional protocols. The same RRC signaling infrastructure used for connected state management is extended to handle non-connected state configurations, avoiding the need for entirely new signaling protocols and reducing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)
