Solution Overview

Problem

In wireless telecommunications networks, particularly in 5G networks, there is a challenge in maintaining effective communication between user equipment (UE) and network nodes due to poor beam correspondence, leading to suboptimal uplink and downlink performance.

Innovation Solution

A method is introduced where user equipment determines its current operating conditions and identifies or generates an antenna configuration to maintain correspondence between transmission and reception beams. This involves storing configurations for known conditions, performing a reference signal sweep when no configuration is found, and interpolating or extrapolating configurations for other conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If antenna configuration is stored and applied for current operating conditions, then beam correspondence is maintained and communication performance is improved, but device complexity increases due to storage and management of multiple configurations

Engineering Contradiction:

Improvebeam correspondenceVSAvoidantenna configuration management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs reference signal sweep procedures in advance to identify and store optimal antenna configurations for various operating conditions before they are needed. This preliminary action creates a lookup table of pre-determined configurations that can be quickly applied when operating conditions change, avoiding the need for complex real-time calculations and reducing device complexity during operation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of performing complex beam correspondence calculations for each operating condition, the system creates simplified copies (stored antenna configurations) that represent the optimal settings for specific conditions. These copied configurations can be directly applied without re-computation, reducing the complexity of real-time configuration management while maintaining reliable beam correspondence.

Inventive Principle:

Principle #26Copying

2Reliability

If reference signal sweep procedure is performed to identify antenna configuration, then beam correspondence is achieved, but loss of time occurs due to the sweep procedure

Engineering Contradiction:

Improvebeam correspondenceVSAvoidreference signal sweep duration

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The reference signal sweep procedure is performed in advance during initialization or when operating conditions change significantly, rather than continuously. The results are stored for future use, so when the same operating conditions occur again, the pre-identified antenna configuration can be applied immediately without repeating the time-consuming sweep procedure.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The reference signal sweep is performed periodically or event-driven (e.g., when operating conditions change) rather than continuously. This periodic approach reduces the total time spent on sweep procedures by only executing them when necessary, while maintaining beam correspondence through the use of stored configurations during intermediate periods.

Inventive Principle:

Principle #19Periodic action

3Adaptability or versatility

If antenna configuration is stored for multiple operating conditions, then adaptability is improved, but loss of memory resources increases

Engineering Contradiction:

Improveoperating condition coverageVSAvoidmemory resources

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

Instead of storing complete antenna configurations for all possible operating conditions, the system stores configurations only for locally relevant or frequently encountered conditions. The stored configurations are tailored to specific local operating scenarios, providing adequate adaptability for typical conditions while minimizing memory usage by not storing redundant or rarely used configurations.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The stored antenna configurations are designed to serve multiple purposes and cover ranges of operating conditions rather than being specific to single conditions. A single stored configuration can be applied to multiple similar operating scenarios, reducing the total number of configurations needed while maintaining broad adaptability across different operating conditions.

Inventive Principle:

Principle #6Universality (Multi-functionality)
