Measurement Gap Determination for NR Bandwidth Parts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing measurement gap modes in LTE systems are not suitable for New Radio (NR) systems, leading to an excessive number of measurement gaps due to differences in synchronization signal design, which can disrupt communication services.
Innovation Solution
User Equipment (UE) receives measurement configuration information about actually transmitted Synchronization Signals (SS) blocks on Bandwidth Parts (BWP), determining measurement gaps only where SS blocks are transmitted, reducing unnecessary gaps by operating on BWPs with no SS block transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LTE measurement gap modes are adopted in NR system, then measurement coverage is ensured, but the quantity of measurement gaps becomes excessive
Solution Approach 1:
The patent applies local quality by configuring measurement gaps specifically for BWPs where SS blocks are actually transmitted, rather than applying a uniform measurement gap configuration across all BWPs. The network device determines measurement gap configurations based on the actual SS block transmission locations in different BWPs, making the measurement gap arrangement localized and adaptive to actual signal conditions.
Solution Approach 2:
The patent implements dynamics by making measurement gap configurations flexible and adaptive rather than fixed. The network device can dynamically adjust measurement gap configurations based on UE capabilities, BWP characteristics, and actual SS block transmission patterns. This allows the system to optimize measurement gap usage according to changing conditions, reducing unnecessary measurement gaps while ensuring adequate measurement coverage where needed.
2Reliability
If measurement gaps are increased to ensure measurement coverage, then measurement reliability improves, but service interruption increases
Solution Approach 1:
By applying measurement gaps only to BWPs where SS blocks are actually transmitted, the patent minimizes the total duration and frequency of measurement gaps. This localized approach ensures measurement reliability is maintained in necessary areas while avoiding unnecessary service interruptions in BWPs without SS block transmissions.
Solution Approach 2:
The dynamic configuration of measurement gaps allows the system to adapt measurement timing and duration to actual needs. The network can adjust measurement gap patterns based on traffic conditions, UE mobility, and SS block transmission schedules, thereby maintaining measurement reliability while minimizing impact on service continuity.

AI summary
A measurement gap determination method, a UE and a network side device are provided. The measurement gap determination method includes: receiving, by a UE, measurement configuration information of a SS block of at least one BWP transmitted from a network side device, wherein the UE operates at the BWP on which no SS block is transmitted when the UE receives the measurement configuration information; determining, by the UE, a measurement gap for the measurement of the SS block on the at least one BWP in accordance with the measurement configuration information; and measuring, by the UE, the SS block on the at least one BWP in the measurement gap.
