Terminal Data Transmission Control via Link Quality

Solution Overview

Problem

Existing data transmission methods in terminal devices lead to high power consumption due to the need for increased power when link quality is poor, resulting in inefficient energy usage.

Innovation Solution

A method and terminal device that acquire link quality and determine whether to transmit data based on preset thresholds, adjusting transmission power accordingly to optimize energy use by correlating data transmission conditions with link quality.

Engineering Contradictions & Design Principles

1Reliability

If data transmission power is increased when link quality is poor, then data transmission reliability is improved, but terminal power consumption increases

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidterminal power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The terminal device performs preliminary actions by acquiring link quality information before data transmission occurs. The network side device sends downlink reference signals, and the terminal measures downlink reference signal received power (RSRP) and downlink reference signal received quality (RSRQ) in advance. Based on these preliminary measurements, the terminal determines whether to perform uplink data transmission, avoiding unnecessary high-power transmission when link quality is poor.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms where the terminal feeds back link quality information to the network side device. The terminal measures downlink link quality and feeds back RSRP and RSRQ values. The network side device uses this feedback information to adjust downlink transmission parameters, creating a closed-loop control system that optimizes both reliability and power consumption.

Principle #23Feedback

2Reliability

If data transmission is performed with high power when link quality is poor, then data transmission reliability is improved, but energy efficiency deteriorates

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidenergy efficiency

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The terminal device performs preliminary actions by acquiring link quality information before data transmission occurs. The network side device sends downlink reference signals, and the terminal measures downlink reference signal received power (RSRP) and downlink reference signal received quality (RSRQ) in advance. Based on these preliminary measurements, the terminal determines whether to perform uplink data transmission, avoiding unnecessary high-power transmission when link quality is poor.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically changes transmission parameters based on measured link quality. The terminal adjusts transmission decisions by comparing measured RSRP and RSRQ values against threshold parameters. When link quality metrics fall below thresholds, the terminal changes its transmission parameter from high-power transmission to transmission cancellation, optimizing energy efficiency while maintaining reliability when conditions permit.
