Solution Overview

Problem

Smart repeaters in high-frequency communication scenarios face challenges in determining the forwarding state of resources, which is crucial for implementing smart amplify-and-forward operations to save power and reduce interference, but existing methods are inadequate.

Innovation Solution

A method and apparatus where a first communication node acquires and determines the forwarding state of a resource based on configuration information, including resource transmission direction and forwarding state configuration, allowing for downlink, uplink, or no forwarding operations, and a second communication node configures and sends this information to determine the forwarding state.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If smart repeater performs amplify-and-forward operations on all resources, then network coverage is improved, but power consumption increases and interference is generated

Engineering Contradiction:
Improvenetwork coverageVSAvoidpower consumption
Core Design Contradiction:
Area of stationary objectVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the forwarding state configurable and adjustable based on network conditions. The smart repeater can dynamically switch between different forwarding states (DL forwarding, UL forwarding, or no forwarding) for different resources, allowing adaptive power consumption management while maintaining necessary network coverage.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements local quality by allowing different forwarding states to be applied to different resources (time slots, frequency resources, or spatial resources). This enables selective amplification only where needed, reducing overall power consumption while maintaining coverage in critical areas.

Inventive Principle:
Principle #3Local quality

2Area of stationary object

If smart repeater performs amplify-and-forward operations on all resources, then network coverage is improved, but interference is increased

Engineering Contradiction:
Improvenetwork coverageVSAvoidinterference
Core Design Contradiction:
Area of stationary objectVSObject-generated harmful factors

Solution Approach 1:

The patent applies local quality by enabling selective forwarding on a per-resource basis. The network can configure the smart repeater to forward only in specific directions (DL or UL) or on specific resources, thereby localizing the amplification effect and minimizing interference in other spatial, temporal, or spectral domains while maintaining necessary coverage.

Inventive Principle:
Principle #3Local quality

3Device complexity

If forwarding state is determined without configuration information, then device complexity is reduced, but determination accuracy is insufficient

Engineering Contradiction:
Improvedetermination mechanism complexityVSAvoidforwarding state determination accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent introduces configuration information as an intermediary between the network and the smart repeater's forwarding decision mechanism. This configuration information (received via RRC signaling, MAC CE, or DCI) provides the necessary guidance for accurate forwarding state determination without requiring complex autonomous decision-making algorithms in the repeater.

Inventive Principle:
Principle #24Intermediary (Mediator)
