Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Network side devices lack the ability to configure uplink resources that meet the demands of terminals, as they are unaware of the terminals' needs and requirements.

Innovation Solution

Terminals send auxiliary information to network side devices to assist in configuring uplink resources, such as preconfigured physical uplink shared channels, based on their specific needs and requirements, including tendentious configurations and service status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the network side device configures uplink resources without knowing terminal needs, then the configuration process is simple, but the configured resources cannot satisfy terminal demands

Engineering Contradiction:

Improveadaptability of uplink resource configuration to terminal demandsVSAvoidcomplexity of resource configuration process

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The terminal sends auxiliary information to the network side device in advance before actual uplink data transmission. This preliminary action enables the network side device to configure appropriate uplink resources (such as PUR configuration information including time resources, frequency resources, and modulation and coding scheme) before the terminal needs to transmit data, ensuring the resources are pre-prepared and match terminal demands.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal provides feedback information (auxiliary information) to the network side device about its uplink transmission needs. The network side device uses this feedback to adjust and configure the uplink resources accordingly. This feedback mechanism ensures the configured resources accurately reflect terminal demands while maintaining a relatively simple configuration process.

Inventive Principle:

Principle #23Feedback

2Productivity

If the network side device configures uplink resources without terminal information, then the configuration process is fast, but resource utilization is inefficient

Engineering Contradiction:

Improveefficiency of uplink resource utilizationVSAvoidtime required for resource configuration

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The terminal sends auxiliary information in advance before data transmission is needed. This allows the network side device to pre-configure uplink resources (selecting appropriate time resources, frequency resources, and modulation and coding scheme) so that when the terminal needs to transmit, the resources are already ready and optimized, avoiding last-minute configuration delays and improving overall resource utilization efficiency.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal actively provides its own needs information (auxiliary information including service status and tendentious configuration) to the network side device. This self-service approach enables the network to configure resources that precisely match terminal requirements, improving resource utilization efficiency without requiring extensive network-side investigation or trial-and-error configuration.

Inventive Principle:

Principle #25Self-service

3Loss of energy

If the network side device configures uplink resources without knowing terminal needs, then the configuration process is simple, but unnecessary overheads are generated

Engineering Contradiction:

Improveenergy consumption related to uplink resource overheadVSAvoidcomplexity of terminal-network coordination

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The terminal extracts and sends only the necessary auxiliary information (such as service status indicator and tendentious configuration indicator) to the network side device. This extraction of essential information allows the network to configure uplink resources efficiently without requiring extensive data exchange, thereby reducing unnecessary overheads and energy consumption while maintaining relatively simple coordination complexity.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The terminal and network side device use parameter indicators (such as service status indicator with values like first indicator value indicating need for PUR, second indicator value indicating no need, and tendentious configuration indicator) to convey essential information concisely. This parameter-based communication reduces the amount of data transmitted, minimizing overheads and energy consumption while achieving effective resource configuration.

Inventive Principle:
