UE Slot Format Timing for Lower-Complexity Wireless Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently determining slot formats, leading to increased processing complexity and power consumption, particularly for low-complexity or low-power user equipment (UEs), due to the need for immediate and frequent slot format adjustments.
Innovation Solution
User equipment (UE) is allowed to wait for a time delay or duration before determining slot formats, reducing processing complexity and power consumption by using a time parameter or duration after receiving a dynamic indication, thereby relaxing the slot format determination process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the UE determines slot format immediately upon receiving dynamic indication, then the communication responsiveness is improved, but the processing complexity and power consumption increase
Solution Approach 1:
The patent applies preliminary action by having the UE determine slot format in advance based on configured time delay parameters. The UE receives dynamic indication and then determines the slot format after a configured time delay, which allows the UE to prepare for the determination in advance rather than reacting immediately, thereby reducing processing complexity and power consumption while maintaining communication responsiveness.
2Productivity
If the UE continuously monitors for slot format indications, then the communication efficiency is improved, but the power consumption increases
Solution Approach 1:
The patent applies periodic action by configuring the UE to monitor for slot format indications at specific periodic intervals rather than continuously. The UE monitors for a configured duration or until a configured time delay expires, then stops monitoring. This periodic monitoring approach maintains communication efficiency by ensuring the UE is alert when needed while significantly reducing power consumption by allowing the UE to enter lower-power states between monitoring intervals.
3Loss of time
If the UE applies slot format configuration immediately, then the communication responsiveness is improved, but the processing time required increases
Solution Approach 1:
The patent applies parameter changes by modifying the time parameters associated with slot format determination. Instead of immediate application, the UE is configured with time delay parameters that adjust when the slot format determination occurs. The UE determines the slot format after a configured time delay, which changes the temporal parameter of the determination process. This parameter change allows the UE to balance responsiveness with processing time requirements, ensuring that the UE has sufficient time to process the determination without causing excessive delays in communication.
Data Source
AI summary
Methods, systems, and devices for wireless communications are described. A base station may transmit an indication of a time parameter (e.g., a time delay or a configured duration) associated with determining a configuration for a slot duration. A user equipment (UE) may identify the time parameter and receive an indication of a slot configuration. The UE may determine the configuration of one or more slot durations based on the received indication and according to the time parameter. For instance, the UE may determine the configuration of one or more slots after the time delay. In some other examples, the UE may determine the configuration of one or more slots within the configured duration, and may not use different slot configurations until after the duration expires. The base station and the UE may communicate during the one or more slot durations based on the slot configuration and using the time parameter.
