Independent Measurement Gap Configuration for 5G NR-U
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G NR-U technologies face challenges in configuring independent measurement gaps for user equipment (UE) in unlicensed spectrum, which affects efficient data collection and network performance, particularly in scenarios involving multiple radio access technologies and spectrum types.
Innovation Solution
The method involves a network cell establishing a connection with UE, receiving an indication of independent measurement gap support for NR-U, and transmitting measurement gap configuration information to the UE, allowing it to configure a measurement gap pattern tailored for NR-U operations, enabling concurrent independent measurement gaps for different spectrum types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single measurement gap pattern is configured for multiple measurement types (5G NR and 5G NR-U), then device complexity is reduced, but measurement precision and reliability deteriorate due to inability to optimize gaps for specific spectrum characteristics
Solution Approach 1:
The patent segments the measurement gap configuration into separate independent patterns: one for 5G NR (licensed spectrum) and another for 5G NR-U (unlicensed spectrum). This allows each measurement gap pattern to be independently optimized for its specific spectrum type, resolving the contradiction between device complexity and measurement precision by dividing the unified configuration into specialized sub-configurations.
2Measurement precision
If independent measurement gap configuration is implemented for 5G NR-U, then measurement precision and network performance improve, but device complexity and configuration overhead increase
Solution Approach 1:
The patent implements dynamic measurement gap configuration where the UE can be configured with different measurement gap patterns based on the specific measurement type and spectrum characteristics. The configuration is flexible and adaptable, allowing the network to dynamically select appropriate gap patterns for 5G NR-U measurements, thereby achieving high measurement precision without permanently increasing device complexity.
3Adaptability or versatility
If measurement gaps are configured for both 5G NR and 5G NR-U simultaneously, then versatility and adaptability improve, but loss of time increases due to coordination overhead and potential conflicts
Solution Approach 1:
The patent segments measurement operations into distinct time windows and gap patterns for different spectrum types. By separating 5G NR and 5G NR-U measurements into independent gap configurations, the system eliminates coordination conflicts and time losses associated with managing simultaneous measurements in a unified gap structure.

AI summary
A network cell is connected to a user equipment (UE) that supports an independent measurement gap configuration. The cell establishes a connection to the UE, receives an indication that the UE supports an independent measurement gap configuration for new radio in an unlicensed spectrum (NR-U) and transmits measurement gap configuration information to the UE, wherein the UE configures a measurement gap pattern based on the measurement gap configuration information.
