Solution Overview

Problem

Existing wireless communication technologies face challenges in meeting the low latency requirements for uplink data transmission in 5G networks, particularly due to the need for scheduling requests and resource allocation by the base station, which can complicate and delay the data transmission process.

Innovation Solution

A method and device for transmitting uplink data using preconfigured resources, allowing UEs to transmit data without immediate scheduling requests, by providing assistance information and configuration information for utilizing preconfigured uplink resources.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If scheduling request and resource allocation procedures are used for uplink data transmission, then the base station can allocate resources efficiently, but the transmission latency increases

Engineering Contradiction:

Improveresource allocation efficiencyVSAvoidtransmission latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent applies preliminary action by pre-configuring uplink resources at the base station before the UE needs to transmit data. The base station allocates and reserves uplink resources in advance, so when the UE has data to transmit, it can immediately use the pre-configured resources without going through the standard scheduling request and resource allocation procedure, thereby reducing latency while maintaining efficient resource management

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements self-service by enabling the UE to autonomously select and use pre-configured uplink resources without requiring real-time scheduling requests to the base station. The UE can independently transmit uplink data using the previously configured resources, eliminating the need for interactive scheduling procedures and reducing transmission delay

Inventive Principle:

Principle #25Self-service

2Productivity

If preconfigured uplink resources are used for data transmission, then transmission speed increases, but resource management complexity increases

Engineering Contradiction:

Improvedata transmission speedVSAvoidresource management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent uses an intermediary approach by introducing a pre-configuration phase where the base station acts as a mediator to allocate and configure uplink resources in advance. This intermediary configuration step simplifies subsequent transmissions by establishing a clear resource mapping beforehand, reducing the complexity of real-time resource management while enabling fast data transmission

Inventive Principle:

Principle #24Intermediary (Mediator)
