Carrier Measurement Gap Control for Faster 5G Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in 5G networks, performing carrier measurements during connection setup can be delayed due to limited measurement capabilities and inefficient use of measurement gaps, leading to incomplete early measurement reporting and prolonged connection setup times.
Innovation Solution
Implementing a predefined measurement gap pattern for user equipment during connection setup, configured by the network, to facilitate timely and accurate carrier measurements, including early measurement reporting.

Engineering Contradiction Analysis
1Measurement precision
If measurements are performed during connection setup using existing measurement gap patterns, then measurement capabilities are utilized, but connection setup time is prolonged due to delayed and incomplete measurement reporting
Solution Approach 1:
The network configures the user equipment with a measurement gap pattern before connection setup begins. This preliminary configuration enables the user equipment to perform carrier measurements during the connection setup procedure itself, rather than waiting for connection establishment. The measurement gap pattern is pre-defined with specific timing parameters that align with the connection setup timeline, allowing measurements to be completed and reported within the same connection setup message, thereby reducing overall connection setup time while ensuring complete measurement reporting.
2Measurement precision
If measurement gap patterns are configured to enable complete carrier measurements, then measurement accuracy is improved, but measurement timing flexibility is reduced
Solution Approach 1:
The measurement gap pattern configuration includes dynamic parameters such as gap offset, gap length, and gap repetition period that can be adjusted by the network based on specific deployment scenarios and carrier frequencies. This dynamic configuration allows the system to adapt the measurement timing to different network conditions while maintaining complete and accurate carrier measurements. The flexible parameters enable optimization for various situations without sacrificing measurement completeness.
