Solution Overview

Problem

User Equipment (UE) experiences high power consumption when communicating via sidelinks due to the lack of efficient power management techniques.

Innovation Solution

A method and apparatus for processing transmission power level information, where a first UE determines transmission power level information based on a correspondence between transmission power levels and transmission power regions, and sends this information to a second UE, allowing the second UE to determine its transmission power without measuring the first UE's power.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the second UE measures the transmission power of the first UE to determine its own transmission power, then the transmission power control accuracy is improved, but the power consumption of the second UE increases

Engineering Contradiction:

Improvetransmission power control accuracyVSAvoidpower consumption of second UE

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The patent extracts the transmission power measurement function from the second UE and relocates it to the first UE. The first UE measures its own transmission power and sends this information to the second UE, eliminating the need for the second UE to perform power measurement operations, thus reducing its power consumption while maintaining accurate power control.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces transmission power level information as an intermediary carrier. Instead of direct measurement by the second UE, the first UE's transmission power is converted into level information that is transmitted to the second UE, which then uses this information to determine its own transmission power without performing measurements.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the second UE continuously monitors and measures transmission power, then the reliability of power control is improved, but the power consumption increases

Engineering Contradiction:

Improvereliability of power controlVSAvoidpower consumption of second UE

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary action by having the first UE measure and report its transmission power level information before the second UE needs to determine its transmission power. This advance provision of power information eliminates the need for continuous monitoring and measurement by the second UE, maintaining reliable power control while significantly reducing power consumption.

Inventive Principle:

Principle #10Preliminary action
