Solution Overview

Problem

Existing beam indication methods require significant signaling overheads and lack flexibility due to the independent configuration of channels and reference signals, limiting efficient communication in multi-antenna systems.

Innovation Solution

A method for determining beam information that involves configuring a candidate beam information pool for both downlink and uplink channels or reference signals, allowing for shared beam information determination based on this pool to reduce signaling overheads and enhance flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If beam information is configured or indicated independently for each channel or reference signal, then beam indication can be performed for each channel or reference signal separately, but signaling overheads increase significantly

Engineering Contradiction:
Improvebeam indication capabilityVSAvoidsignaling overhead
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent merges the beam information configuration for multiple channels and reference signals into a unified candidate beam information pool. Instead of independently configuring beam information for each channel or reference signal, the system creates a shared pool that contains candidate beam information that can be reused across multiple downlink and uplink channels and reference signals, thereby reducing redundant signaling overhead while maintaining the ability to provide beam indication for each entity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The candidate beam information pool serves multiple functions simultaneously - it provides beam information for downlink channels, uplink channels, and reference signals. This universal pool can be configured once and then used to indicate beam information across multiple different channel types and reference signal types, making the beam indication system more efficient and reducing the total amount of signaling required.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If beam information is configured independently for each channel or reference signal, then specific beam requirements can be met, but the system lacks flexibility in beam indication

Engineering Contradiction:
Improvebeam indication accuracyVSAvoidbeam indication flexibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces dynamic selection capability within the unified candidate beam information pool. The system can dynamically select which candidate beam information from the pool to apply to specific channels or reference signals based on current communication conditions, channel types, and signal requirements. This dynamic approach provides both flexibility in beam indication and maintains reliability by allowing specific beam selection when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent segments the beam information configuration into a structured candidate pool that can be selectively applied. The candidate beam information pool is organized in a way that allows different candidate beams to be assigned to different channel types or reference signal types based on specific requirements, providing both flexibility and targeted accuracy for each channel or signal.

Inventive Principle:
Principle #1Segmentation
