UE Switching Time Parameters for 5G Measurement Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment (UE) without a spare RF chain faces challenges in performing measurements without gaps, leading to inefficiencies and resource wastage due to unknown switching times between measurement and transmission/reception, which affects scheduling efficiency and increases error rates.
Innovation Solution
The UE determines and transmits parameters such as time periods for switching between synchronization signal block measurements and transmission/reception to the network, allowing the network to optimize resource grants and minimize interruptions during measurements.

Engineering Contradiction Analysis
1Loss of time
If UE performs measurements without gaps using a spare RF chain, then measurement continuity is improved, but device complexity increases due to requiring additional RF chains
Solution Approach 1:
The UE determines and reports switching time parameters in advance before measurements are performed. This allows the network to pre-configure resource grants and scheduling parameters, enabling the UE to switch between measurement and transmission/reception modes efficiently without requiring a spare RF chain, thus eliminating measurement gaps without increasing device complexity
Solution Approach 2:
The patent introduces dynamic switching time parameters that allow the UE to flexibly transition between measurement and transmission/reception modes. By reporting these switching time parameters to the network, the system can dynamically adjust scheduling to accommodate measurement activities without requiring additional hardware resources, resolving the contradiction between measurement continuity and device complexity
2Productivity
If UE switches between measurement and transmission without known switching times, then resource allocation is simplified, but scheduling efficiency deteriorates and error rates increase
Solution Approach 1:
The UE reports switching time parameters to the network entity, providing feedback about the time required to switch between measurement and transmission/reception modes. This feedback enables the network to accurately schedule resource grants, avoiding conflicts and optimizing scheduling efficiency, thereby resolving the contradiction between simplified resource allocation and scheduling efficiency
