Intermittent Usable Time Domain Resources for 5G UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Higher frequency bands in 5G NR networks, such as FR2, increase UE complexity due to shorter symbol durations and higher subcarrier spacings, leading to increased phase noise, peak-to-average-power ratio, and higher processing loads, which result in increased cost and power consumption.
Innovation Solution
Configuring intermittent usable time domain resources (TDR) for UE, allowing for reduced average complexity by selectively allocating time resources for communication, using a usable TDR configuration that indicates available time resources for communication, which can be semi-statically or dynamically configured, and includes a reduction factor or pattern mask to optimize resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If higher frequency bands (FR2 or higher) are used for communication, then communication capacity and speed are improved, but UE complexity increases due to shorter symbol durations and higher subcarrier spacings
Solution Approach 1:
The patent applies periodic action by configuring intermittent usable time domain resources where the UE only needs to perform DFT operations during specific periodic intervals rather than continuously. The network configures a pattern of usable time resources that repeats periodically, allowing the UE to enter low-power states during non-usable periods while maintaining communication capability during usable periods, thus reducing average complexity while preserving high-speed communication capability when needed
2Reliability
If continuous time resources are allocated to UE, then communication reliability is improved, but power consumption increases
Solution Approach 1:
The patent applies dynamics by making the time resource allocation dynamic rather than static. The network can configure and update the pattern of usable time resources adaptively based on traffic conditions, channel quality, and UE capabilities. This dynamic configuration allows the system to maintain reliable communication during critical periods while reducing power consumption during periods with lower traffic demands, achieving an optimal balance between reliability and energy efficiency
3Productivity
If more DFT operations are performed per unit time, then processing capability is improved, but UE complexity and cost increase
Solution Approach 1:
The patent applies partial action by having the UE perform DFT operations only during the configured usable time resources rather than continuously. The UE performs the necessary processing capability during these partial intervals, which is sufficient to maintain communication reliability while significantly reducing the average processing load and associated complexity and cost

AI summary
Aspects relate to techniques for configuring intermittent time domain resources that are usable by a user equipment (UE) for communication with a base station. The base station may transmit a usable time domain resource (TDR) configuration to the UE that indicates the usable time resources that are available to the UE for communication with the base station. The UE may then communicate with the base station based on the usable TDR configuration.
