Solution Overview

Problem

Existing communication technologies face challenges in detecting events triggered by terminals to determine if they can execute relaxation mechanisms, such as extended measurement gaps for reducing power consumption and improving terminal endurance.

Innovation Solution

A measurement method and apparatus that allow terminals to obtain measurement values for radio link monitor (RLM) and radio resource management (RRM) measurements, and determine target events like relaxation entering or exiting based on these values and reference information, enabling the terminal to report these events to the network device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If measurement gap is extended for relaxation mechanism, then power consumption is reduced and terminal endurance is improved, but ability to detect relaxation events is lost

Engineering Contradiction:

Improvepower consumptionVSAvoidevent detection capability

Core Design Contradiction:

Use of energy by moving objectVSDifficulty of detecting and measuring

Solution Approach 1:

The network device pre-configures reference information including measurement parameters and event triggering conditions before the terminal enters relaxation mode. This allows the terminal to have event detection capability ready in advance without needing continuous measurement gaps during relaxation.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system dynamically adjusts measurement behavior based on terminal state. During non-relaxation periods, normal measurements occur; during relaxation periods, measurements are suspended but event detection can still occur using pre-configured parameters, creating a flexible adaptive measurement system.

Inventive Principle:

Principle #15Dynamics

2Duration of action of stationary object

If measurement gap is extended for relaxation mechanism, then terminal endurance is improved, but measurement precision may be affected

Engineering Contradiction:

Improveterminal enduranceVSAvoidmeasurement accuracy

Core Design Contradiction:

Duration of action of stationary objectVSMeasurement precision

Solution Approach 1:

The system changes measurement parameters based on terminal state. During relaxation mode, the terminal uses pre-configured reference information with appropriate measurement parameters that balance accuracy requirements with power saving goals, rather than using fixed measurement configurations.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The terminal reports detected events and measurement values to the network device, which uses this feedback to adjust future measurement configurations and relaxation parameters, continuously optimizing the balance between measurement precision and power consumption.

Inventive Principle:

Principle #23Feedback

AI summary

A measurement method is performed by a terminal, and includes: obtaining a measurement value of a target measurement, wherein the target measurement includes at least one of a radio link monitor (RLM) measurement or a radio resource management (RRM) measurement; and determining a target event triggered by the terminal based on the measurement value and reference information corresponding to the target measurement, wherein the target event includes a relaxation entering event or a relaxation exiting event.
