Solution Overview

Problem

Existing sending methods for assistance communication devices in communication systems have high complexity and poor applicability due to the need for separate algorithms to jointly design the precoding of smart repeaters/RIS and base stations.

Innovation Solution

The proposed solution involves obtaining indication information, including channel state information (CSI) and/or a sending scheme, for assistance communication devices, and executing precoding based on this information to facilitate signal transceiving.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate algorithms are used to jointly design the precoding of smart repeaters/RIS and base stations, then channel control capability is improved, but system complexity increases

Engineering Contradiction:
Improvechannel control capabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the precoding design into two independent parts: base station precoding and assistance communication device precoding. Each part has its own algorithm and optimization process, eliminating the need for complex joint design while maintaining channel control capability through coordinated operation of the segmented components.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces indication information as an intermediary that carries channel state information and precoding parameters between the base station and assistance communication devices. This intermediary mechanism enables coordinated precoding without requiring complex joint algorithms, as the indication information mediates the interaction between independent precoding designs.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If separate algorithms are used to jointly design the precoding of smart repeaters/RIS and base stations, then channel control capability is improved, but applicability deteriorates

Engineering Contradiction:
Improvechannel control capabilityVSAvoidapplicability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

By segmenting the precoding into independent base station and assistance device components, the system becomes more adaptable to different deployment scenarios. Each segmented component can be independently configured and optimized for specific use cases, improving overall applicability while maintaining channel control.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a universal precoding framework where the base station generates indication information that can be applied to multiple types of assistance communication devices (RIS, smart repeaters, etc.). This multi-functional approach enhances applicability across different device types and deployment scenarios without requiring device-specific joint algorithms.

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

3Productivity

If assistance communication devices execute precoding based on obtained CSI and sending schemes, then computing resource distribution is improved, but information processing requirements increase

Engineering Contradiction:
Improvecomputing resource distributionVSAvoidinformation processing requirements
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The base station performs preliminary computation by generating comprehensive indication information containing channel state information and precoding parameters before transmission to assistance devices. This preliminary action reduces the information processing burden on assistance devices, as they receive pre-processed data rather than needing to perform complex computations themselves.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a feedback mechanism where terminal devices provide channel state information to the base station, which then generates appropriate precoding parameters. This feedback loop enables the base station to pre-compute optimal precoding solutions based on actual channel conditions, improving computing resource distribution while managing information processing requirements through intelligent feedback-driven parameter generation.

Inventive Principle:
Principle #23Feedback
