Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The speed of Secondary Cell (SCell) configuration in carrier aggregation technology is slow due to the terminal performing measurements and reporting only after an RRC connection is established, which impacts service performance.

Innovation Solution

Performing measurements in a non-connected state and transmitting an uplink message during the connection establishment procedure to indicate valid measurement results, allowing the network to rapidly acquire and utilize these results for SCell configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If the terminal performs measurement and reporting only after RRC connection establishment is completed, then the connection establishment procedure is simplified, but the SCell configuration speed becomes slow

Engineering Contradiction:

Improveconnection establishment procedureVSAvoidSCell configuration speed

Core Design Contradiction:

Device complexityVSProductivity

Solution Approach 1:

The terminal performs measurement in the non-connected state before RRC connection establishment, and reports measurement results through uplink messages during connection establishment. This preliminary action allows the network to obtain measurement results earlier, accelerating SCell configuration speed without complicating the connection establishment procedure.

2Ease of manufacture

If the terminal performs measurement after RRC connection establishment, then the measurement process is straightforward, but the service performance of the terminal is impacted

Engineering Contradiction:

Improvemeasurement processVSAvoidservice performance

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The terminal performs measurement in advance during the non-connected state and reports results through uplink messages before or during connection establishment. This ensures measurement results are available when needed for SCell configuration, improving service performance while maintaining measurement process simplicity.

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If measurement and reporting are performed after connection establishment, then the system state management is simplified, but the speed of acquiring measurement results is reduced

Engineering Contradiction:

Improvesystem state managementVSAvoidmeasurement result acquisition speed

Core Design Contradiction:

Ease of operationVSSpeed

Solution Approach 1:

The terminal performs measurement and reports results through uplink messages during the connection establishment procedure. The network acquires measurement results earlier by receiving them in uplink messages before or during connection establishment, thereby increasing the speed of measurement result acquisition while keeping system state management simple.

AI summary

An indication method for a measurement result, a terminal and a base station are provided. The method includes: performing measurement in a non-connected state to obtain a measurement result; transmitting an uplink message to a base station, the uplink message being at least used to indicate that the measurement result is valid; wherein the uplink message is an uplink message in a connection establishment procedure between the terminal and the base station, or the uplink message is an uplink message transmitted after the connection establishment procedure between the terminal and the base station is completed.
