Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE wireless communication systems, unclear specifications for handling system information reception with measurement gap configuration lead to potential delays in UE performance, cell access, and increased burden on eNBs due to unclear handling of measurement gaps during system information reception.
Innovation Solution
A method and device that prioritize the reception of system information over measurement gaps, ensuring timely acquisition of critical system information like MIB and SIB, and allow measurement to be performed within gaps, thereby avoiding delays and reducing network scheduling burdens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the UE performs measurements during configured measurement gaps, then measurement accuracy is improved, but system information reception is delayed or interrupted
Solution Approach 1:
The measurement gap configuration is made dynamic and adaptable. Instead of fixed measurement gaps that always collide with system information reception, the UE dynamically adjusts measurement gap usage based on whether system information reception is currently active. When system information reception is detected, the UE temporarily suspends measurement activities in those gaps, allowing the system to switch between measurement and reception modes flexibly without permanent collision.
Solution Approach 2:
The UE performs preliminary detection to determine whether system information reception is scheduled during configured measurement gaps. By detecting the system information reception schedule in advance and comparing it with measurement gap configurations, the UE can proactively adjust measurement activities before collisions occur, preventing delays rather than reacting to them afterward.
2Adaptability or versatility
If the eNB schedules measurement gaps for all UEs, then measurement coverage is improved, but network scheduling complexity increases
Solution Approach 1:
The UE performs self-service by autonomously detecting system information reception schedules and independently adjusting its measurement gap utilization. Instead of requiring the eNB to schedule measurement gaps around each UE's system information reception (which would create complex scheduling problems), the UE itself manages the conflict by suspending measurements during reception periods, thereby simplifying network scheduling while maintaining measurement coverage.
3Reliability
If the UE waits for required system information during measurement gaps, then system information completeness is improved, but cell access time increases
Solution Approach 1:
The UE dynamically adjusts its cell access procedure based on the reception status of system information. When system information reception is interrupted by measurement gaps, the UE detects this condition and adapts by extending its cell access preparation time only when necessary. This dynamic adjustment ensures that the UE has complete system information for reliable access while minimizing unnecessary delays when system information is available without interruption.

AI summary
A method of handling system information reception with measurement gap configuration for a mobile device in a wireless communication system is disclosed. The method comprises performing reception of a first system information broadcasted by a network of the wireless communication system, and prioritizing reception of the first system information over utilization of a measurement gap for measurement when the measurement gap overlaps a period for the reception of the first system information, wherein the mobile device is configured with the measurement gap.
