Service-Aware Measurement Gap Configuration for Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, measurement gaps disrupt both uplink and downlink communications, leading to increased jitter and reduced throughput, particularly in scenarios requiring inter-frequency or intra-frequency measurements, and existing configurations are not service-aware, making them unsuitable for various service types like eMBB, URLLC, or critical IoT services.
Innovation Solution
A service-aware measurement gap configuration is implemented, where a RAN device determines the service information of a UE and selects an optimal measurement gap pattern based on the service type, adjusting parameters like gap length, periodicity, and timing advance to optimize performance for specific services, such as high throughput or low latency, and transmits this configuration to the UE.

1Measurement precision
If a measurement gap is configured to enable inter-frequency or intra-frequency measurements, then measurement capability is improved, but communication performance deteriorates due to increased jitter and reduced throughput
Solution Approach 1:
The measurement gap configuration is made dynamic and adaptive rather than static. The RAN device determines service information (eMBB, URLLC, or other service types) and selectively configures measurement gap patterns based on the specific service requirements. This dynamic adaptation allows the system to optimize between measurement capability and communication performance depending on the active service type.
Solution Approach 2:
Different measurement gap patterns with varying parameters (gap length, periodicity, offset) are configured based on service type. For example, URLLC services may use shorter or less frequent measurement gaps compared to eMBB services, changing the temporal parameters of measurement gaps to minimize impact on throughput while maintaining necessary measurement capability.
2Measurement precision
If a measurement gap is configured to enable inter-frequency or intra-frequency measurements, then measurement capability is improved, but communication quality deteriorates due to increased jitter
Solution Approach 1:
The system dynamically adjusts measurement gap configuration based on service type to minimize jitter impact. For latency-sensitive services like URLLC, the RAN device can configure measurement gaps with patterns that reduce interruption frequency or duration, thereby maintaining measurement capability while minimizing jitter and preserving communication reliability.
Solution Approach 2:
By changing measurement gap parameters (length, periodicity, timing advance) according to service requirements, the system optimizes the balance between measurement accuracy and communication quality. Different service types receive tailored measurement gap configurations that minimize their specific performance concerns.

AI summary
In some implementations, a radio access network (RAN) device may determine service information associated with a user equipment (UE). The service information may be associated with a service to be received by the UE. The RAN device may select a measurement gap configuration based on the service information associated with the UE. The RAN device may transmit the measurement gap configuration for reception by the UE.
