UE Uplink Transmission Windows for 5G NR Power Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G NR user equipment (UE) consumes more power during uplink data transmission than 4G communication, necessitating a need for power optimization methods.
Innovation Solution
The UE determines the current application scenario and adjusts data transmission windows accordingly, including periods for data transmission and suspension, to optimize power usage in uplink data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If 5G NR uplink data transmission is performed frequently, then data transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements periodic uplink data transmission by configuring data transmission windows with specific periods for different application scenarios. The UE transmits data periodically within these windows rather than continuously, reducing power consumption while maintaining transmission reliability. Different scenarios (foreground activity, background activity, screen off, do not disturb) have different transmission periods configured by the network
Solution Approach 2:
The patent dynamically adjusts transmission behavior based on application scenarios. The UE determines the current scenario and applies corresponding transmission parameters (periods, window configurations) provided by the network. This dynamic adaptation allows the system to optimize between reliability and power consumption based on actual usage conditions
2Use of energy by moving object
If data transmission windows are configured for different application scenarios, then power optimization is improved, but device complexity increases
Solution Approach 1:
The patent segments the operation into distinct application scenarios (foreground activity, background activity, screen off, do not disturb), each with its own data transmission window configuration. The network provides separate period configurations for each scenario, allowing targeted power optimization without requiring complex real-time analysis. The UE simply determines the current scenario and applies the corresponding pre-configured parameters
Solution Approach 2:
The UE autonomously determines its current application scenario and selects the appropriate transmission window configuration from those provided by the network. This self-service approach allows the UE to optimize its own power consumption without requiring complex network control or additional signaling, reducing overall system complexity while achieving power optimization

AI summary
A power optimization method for uplink data transmission is provided. The power optimization method is applied to user equipment (UE). The power optimization method includes the following steps. The UE determines the current application scenario of the UE. The UE determines the data transmission window corresponding to the current application scenario. Data transmission windows corresponding to different application scenarios of the UE have at least one of different period to transmit data and different period to enter suspension. The UE may transmit data based on the determined data transmission window.
