Solution Overview

Problem

In wireless communication systems, terminal devices perform unnecessary radio resource management (RRM) measurements due to network devices configuring measurements without considering the terminal's status, leading to increased power consumption, especially for static devices with no positional changes relative to serving cells.

Innovation Solution

Implementing a method where network devices receive status information from terminal devices, such as mobile status and channel quality, to configure RRM measurements accordingly, adjusting measurement periods and reporting frequencies based on the terminal's status, thereby reducing unnecessary measurements and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the network device configures RRM measurements continuously without considering terminal status, then the measurement coverage is comprehensive, but the terminal device power consumption increases

Engineering Contradiction:

Improvemeasurement coverageVSAvoidterminal device power consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies dynamics by making the RRM measurement configuration adaptive rather than static. The network device adjusts measurement parameters dynamically based on terminal status information (mobile status and channel quality), allowing the system to transition between different measurement intensities according to real-time conditions, thus resolving the contradiction between comprehensive coverage and power consumption.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes key parameters of the RRM measurement configuration (measurement period, reporting frequency, measurement quantity) based on terminal status. When the terminal is static with good channel quality, parameters are relaxed to reduce power consumption; when the terminal is mobile or channel quality degrades, parameters are tightened to maintain measurement reliability, thereby resolving the contradiction.

Inventive Principle:

Principle #35Parameter changes

2Speed

If the terminal device performs continuous RRM measurements, then the mobility management is timely, but unnecessary measurements waste power consumption

Engineering Contradiction:

Improvemobility management response speedVSAvoidpower consumption

Core Design Contradiction:

SpeedVSLoss of energy

Solution Approach 1:

The patent applies partial action by performing RRM measurements at different intensities based on terminal status. Instead of always performing full measurements, the system performs only necessary measurements - reducing measurement quantity and reporting frequency when terminal status indicates no mobility management is needed, thus eliminating wasted energy while maintaining timely response when actually required.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The patent implements feedback mechanisms where the terminal reports mobile status and channel quality information to the network device, which then adjusts RRM measurement configuration accordingly. This closed-loop feedback ensures measurements are performed at the right intensity - maintaining fast mobility management response when needed while reducing power consumption when the terminal is static and channel conditions are stable.

Inventive Principle:

Principle #23Feedback

3Device complexity

If the network device configures RRM measurements without considering channel quality, then the measurement configuration is simple, but measurement efficiency decreases

Engineering Contradiction:

Improveconfiguration complexityVSAvoidmeasurement efficiency

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The patent applies preliminary action by having the terminal device report mobile status and channel quality information to the network device before the network device configures RRM measurements. This advance information gathering allows the network device to make informed configuration decisions, improving measurement efficiency without significantly increasing overall system complexity, as the information collection is integrated into existing uplink reporting mechanisms.
