Solution Overview

Problem

Existing beam indication methods require large signaling overheads and lack flexibility due to the independent configuration of channels and reference signals, limiting efficient communication.

Innovation Solution

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

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If beam information is configured or indicated independently for each channel or reference signal, then beam information can be accurately determined for each component, but signaling overheads become large

Engineering Contradiction:

Improvebeam information accuracyVSAvoidsignaling overhead

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent merges the beam information configuration into a unified pool that serves multiple channels and reference signals. Instead of independently configuring beam information for each channel, the system creates a common beam information pool that can be shared across different channels, thereby reducing redundant signaling while maintaining accuracy.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The beam information pool is designed with universal applicability, allowing a single set of beam information to serve multiple functions across different channels and reference signals. This multi-functional approach eliminates the need for separate beam information configurations for each channel type.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If beam information is configured independently for each channel or reference signal, then each channel can have optimized beam settings, but flexibility in beam indication is limited

Engineering Contradiction:

Improvechannel-specific beam optimizationVSAvoidbeam indication flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system introduces dynamic selection mechanisms that allow the beam information pool to be adaptively chosen based on the specific channel or reference signal being processed. This enables the system to maintain channel-specific optimization while gaining flexibility through dynamic pool selection and combination.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

While maintaining a unified pool, the system allows different portions or selections of the pool to be applied to different channels based on their specific requirements. This local quality approach enables tailored beam information for each channel while using a common foundation, balancing optimization with flexibility.

Inventive Principle:

Principle #3Local quality
