Solution Overview

Problem

In millimeter wave communication systems, accurately aligning spatial beams between user equipment (UE) and base stations (BS) for efficient wireless communication is challenging due to the need for precise beam measurement and reporting mechanisms.

Innovation Solution

A method and apparatus for beam measurement and reporting are provided, where user equipment determines and transmits capability values and indicators for uplink transmissions, and base stations generate and receive reports to align spatial beams effectively.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If beam measurement and reporting mechanisms are implemented in millimeter wave communication systems, then spatial beam alignment between UE and BS is achieved, but system complexity and measurement precision requirements increase

Engineering Contradiction:

Improvebeam alignment accuracyVSAvoidmeasurement and reporting mechanism complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The beam measurement and reporting process is divided into distinct capability components (e.g., number of beams, frequency ranges, measurement types) that can be independently configured and reported. This segmentation allows the system to manage complexity by handling specific beam capabilities separately rather than as a monolithic complex system.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent utilizes capability indicators and parameters (such as beam formation capability, frequency range support, and measurement type capabilities) that can be dynamically adjusted and reported. These parameter changes enable flexible adaptation of beam measurement mechanisms to different system requirements and UE capabilities, resolving the contradiction between reliability and complexity.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If detailed capability values and indicators are reported for uplink transmissions, then beam alignment precision is improved, but uplink transmission overhead increases

Engineering Contradiction:

Improvebeam measurement precisionVSAvoiduplink transmission overhead

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

The patent extracts only the essential capability indicators needed for beam measurement and reporting from the complete UE capability set. By taking out only the relevant capability values (such as beam-related capabilities) and reporting them separately through dedicated indicators, the system achieves precise beam measurement without transmitting unnecessary information, thus reducing uplink overhead.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system reports capability indicators partially - only when and where they are needed for beam measurement purposes. Rather than reporting all UE capabilities continuously, the patent implements partial reporting mechanisms that provide sufficient precision for beam alignment while minimizing redundant information transmission in the uplink.

Inventive Principle:

Principle #16Partial or excessive action
