Solution Overview

Problem

Current New Radio (NR) systems do not consider backscatter communication (BSC) services in resource configuration, leading to unsupported BSC service transmission.

Innovation Solution

A resource allocation method and apparatus that configure and schedule resources for transmitting BSC channels or signals, including carrier wave, control, and feedback channels, within NR systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If BSC services are not considered in resource configuration, then the NR system maintains simple resource allocation, but BSC service transmission cannot be supported

Engineering Contradiction:

ImproveBSC service transmission supportVSAvoidresource configuration complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments resource allocation by creating separate resource pools for BSC services and traditional NR services. The network device allocates specific time-frequency resources dedicated to BSC channels, signals, and data, allowing independent management and configuration without affecting existing NR resource allocation mechanisms.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent designs a universal resource allocation framework that can handle both traditional NR services and BSC services through a unified scheduling mechanism. The network device uses a single resource allocation apparatus that dynamically assigns resources based on service type, making the system multi-functional without requiring separate dedicated systems.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If specific resources are allocated for BSC channels, then communication reliability for BSC services is improved, but resource allocation complexity increases

Engineering Contradiction:

ImproveBSC communication reliabilityVSAvoidresource allocation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary resource configuration where the network device pre-allocates resource pools for BSC services before actual transmission occurs. Configuration parameters such as time-frequency resources, physical layer parameters, and scheduling rules are established in advance, ensuring reliable BSC communication while simplifying real-time allocation decisions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent incorporates feedback mechanisms where the network device monitors BSC transmission performance and dynamically adjusts resource allocation parameters. Based on channel conditions, traffic demand, and transmission reliability metrics, the system optimizes resource distribution to maintain high reliability while adapting to changing conditions.

Inventive Principle:

Principle #23Feedback
