Wireless Measurement Differentiation for LAA and MulteFire Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks face challenges in differentiating between Licensed Assisted Access (LAA) and MulteFire measurement objects, leading to inefficient handover processes and increased uplink signaling overheads due to the inability to accurately measure channel quality across entire or partial frequency bands of MulteFire networks.
Innovation Solution
A measurement method that transmits configuration information with differentiation indications, allowing terminals to distinguish between LAA, LTE, and MulteFire cells based on Absolute Radio Frequency Channel Numbers (EARFCNs), enabling precise measurement of channel quality across entire or partial frequency bands of MulteFire networks and optimizing handover procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement configuration information does not include differentiation indications, then the terminal cannot distinguish between LAA and MulteFire measurement objects, but including differentiation indications increases uplink signaling overheads
Solution Approach 1:
The patent extracts only the essential differentiation information (EARFCN values) from the measurement configuration and transmits them as compact indication bits rather than full measurement objects. This allows the terminal to distinguish between LAA and MulteFire measurement objects while minimizing the signaling overhead by transmitting only the necessary identifying parameters.
Solution Approach 2:
The patent changes the representation parameter from transmitting complete measurement object configurations to transmitting condensed EARFCN-based differentiation indications. This parameter transformation reduces the signaling data volume while preserving the essential differentiation capability between LAA and MulteFire measurement objects.
2Measurement precision
If the terminal measures entire frequency bands of MulteFire networks, then measurement accuracy improves, but measurement complexity and processing time increase
Solution Approach 1:
The patent segments the MulteFire frequency band measurement into multiple measurement objects, each associated with specific EARFCN values. The terminal can selectively measure individual segments or combinations of segments based on network configuration and handover requirements, reducing overall measurement complexity while maintaining accuracy where needed.
Solution Approach 2:
The patent enables partial measurement action by allowing the terminal to measure only specific frequency bins or subsets of the MulteFire frequency band based on configured EARFCN ranges. This partial measurement approach reduces processing complexity while still providing sufficient accuracy for handover decisions in many scenarios.
3Reliability
If the terminal performs measurements on all configured measurement objects, then handover decision accuracy improves, but handover processing time increases
Solution Approach 1:
The patent performs preliminary configuration of measurement objects with differentiated EARFCN indications during normal operation. When handover is needed, the terminal already has the differentiation information prepared and can quickly identify which measurement objects are relevant, reducing handover processing time while maintaining decision accuracy through the pre-configured differentiation framework.
