Solution Overview

Problem

Existing wireless communication systems face challenges in efficiently managing beams for improved radio interface efficiency and coverage, particularly in high-frequency bands like 28 GHz and 60 GHz, due to hardware constraints and increased propagation loss.

Innovation Solution

Implementing positioning assisted beam management through UE and BS systems that synchronize to a reference source for timing, transmit and receive signals based on configured transmission occasions, and evaluate conditions for beam management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If beam management is implemented in high-frequency bands (28 GHz, 60 GHz), then radio interface efficiency and coverage are improved, but propagation loss increases and transmission distance decreases

Engineering Contradiction:
Improveradio interface efficiencyVSAvoidpropagation loss
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The system performs preliminary synchronization to a reference source (GPS, network timestamp, or base station signal) before beam management operations. This preliminary timing alignment enables accurate determination of transmission occasions and reduces the need for repeated beam training, thereby improving radio interface efficiency while compensating for high propagation loss through optimized timing rather than increased power.

Inventive Principle:
Principle #10Preliminary action

2Productivity

If beam management is implemented in high-frequency bands (28 GHz, 60 GHz), then radio interface efficiency and coverage are improved, but transmission distance is reduced

Engineering Contradiction:
Improveradio interface efficiencyVSAvoidtransmission distance
Core Design Contradiction:
ProductivityVSLength of moving object

Solution Approach 1:

The system dynamically adjusts beam management operations based on timing information from a reference source. Transmission occasions are determined dynamically relative to synchronized timing, allowing the system to adapt beam operations to current channel conditions and device positions. This dynamic approach maintains effective communication over varying distances by optimizing beam timing and direction rather than relying solely on fixed transmission power.

Inventive Principle:
Principle #15Dynamics

3Measurement precision

If synchronization to reference source is implemented for timing information, then beam management accuracy is improved, but device complexity increases

Engineering Contradiction:
Improvetiming accuracyVSAvoidsynchronization mechanism
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The user equipment performs self-synchronization to available reference sources using standard communication protocols. The device autonomously acquires timing information from GPS, network timestamps, or base station signals without requiring complex external synchronization infrastructure. This self-service approach achieves high timing accuracy while minimizing additional device complexity by leveraging existing capabilities.

Inventive Principle:
Principle #25Self-service

4Ease of operation

If transmission occasions are configured with periodicity and offset, then signal coordination is improved, but system complexity increases

Engineering Contradiction:
Improvesignal coordinationVSAvoidconfiguration management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Transmission occasions are configured with periodicity and offset parameters that create regular, predictable transmission patterns. This periodic structure simplifies coordination between devices by establishing fixed time intervals for beam management signals, making it easier to predict and schedule transmissions without requiring complex real-time negotiation. The periodic action reduces configuration complexity compared to fully dynamic scheduling.

Inventive Principle:
Principle #19Periodic action

AI summary

Methods and apparatuses for positioning assisted beam management. A method of operating a user equipment (UE) includes receiving first configuration information for one or more transmission occasions for one or more first signals, respectively, that indicates periodicity of the one or more transmission occasions and an offset relative to a reference source and synchronizing to the reference source for timing information. The method further includes evaluating a condition to transmit a first signal from the one or more first signals, determining the first signal, and when the condition is satisfied, transmitting the first signal in a corresponding transmission occasion and receiving, in response to the first signal, a second signal for beam management.
