LTE MulteFire Measurement Object Differentiation via Configuration IEs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing communication technologies, such as Licensed Assistant Access (LAA) and MulteFire, face challenges in distinguishing measurement objects for handover processes between LTE-based networks and MulteFire-based networks, as both use the same frequency band, leading to confusion and inefficiencies in channel quality measurements.
Innovation Solution
A method is introduced to differentiate measurement objects by using a combination of measurement object configuration and measurement report configuration Information Elements (IEs) to indicate the Radio Access Technology (RAT) type, allowing base stations and User Equipment (UE) to accurately identify and measure channel quality for neighboring cells, thereby facilitating handovers between different network types.

Engineering Contradiction Analysis
1Use of energy by moving object
If the same frequency band is used for both LAA and MulteFire, then spectrum utilization is improved, but measurement object differentiation becomes difficult
Solution Approach 1:
The patent segments the measurement object identification by introducing distinct Information Elements (IEs) for LAA and MulteFire measurement configurations. The LAA measurement configuration includes an laa-CellIdentity IE, while the MulteFire measurement configuration includes a multeFire-CellIdentity IE. This segmentation allows the system to maintain unified frequency band usage while enabling precise differentiation between measurement objects through structure-specific identification fields.
2Adaptability or versatility
If existing measurement configurations are used without modification, then compatibility with current standards is maintained, but handover between LTE and MulteFire networks cannot be distinguished
Solution Approach 1:
The patent applies local quality by making specific parts of the measurement configuration structure distinct while keeping the overall framework compatible with existing standards. The measurement configuration includes both common fields (carrier frequency, bandwidth) and technology-specific fields (laa-CellIdentity or multeFire-CellIdentity). This allows the system to maintain standard compatibility at the protocol level while enabling clear handover distinction through locally differentiated identification elements.
3Measurement precision
If separate measurement configurations are created for LAA and MulteFire, then measurement accuracy is improved, but configuration complexity increases
Solution Approach 1:
The patent implements universality by designing a unified measurement configuration framework that can accommodate both LAA and MulteFire measurement objects. The base structure of the measurement configuration is common to both technologies, with only the cell identity IE differing. This multi-functional design allows a single configuration mechanism to serve dual purposes, improving measurement identification accuracy while minimizing the increase in configuration complexity through structured reusability.

AI summary
A method for distinguishing a measurement object, a base station and a UE are provided. The method includes: in case of determining to configure the UE to perform measurement to a neighboring cell, generating measurement configuration for the neighboring cell, wherein the measurement configuration includes a measurement object configuration IE and a measurement report configuration IE, and the measurement object configuration IE or a combination of the measurement object configuration IE and the measurement report configuration IE is used to indicate a RAT type of the measurement configuration; transmitting the measurement configuration to the UE so as to instruct the UE to perform measurement to a measurement object indicated in the measurement configuration; and receiving a measurement result message transmitted by the UE through a measurement result report IE after the UE performs the measurement to the measurement object.
