Wireless Downlink Scheduling with Selectable UE Processing Times
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communications systems are limited by user equipment (UE) processing times and feedback timelines, which restrict the use of communication resources and reduce throughput and efficiency.
Innovation Solution
UEs transmit indications of different processing times and resource quantities to a network entity, allowing the network to schedule communications with relaxed timelines, enabling higher resource usage and increased throughput.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UE processes messages with longer processing times, then throughput and efficiency increase, but latency increases
Solution Approach 1:
The patent implements dynamic processing time adjustment where the UE can operate in different processing time modes (first processing time for lower latency, second processing time for higher throughput). The network entity dynamically selects which mode to use based on current system conditions and message requirements, allowing the system to adapt between latency and throughput priorities as needed.
Solution Approach 2:
The patent changes the processing time parameter from a fixed value to a selectable set of values. By allowing the UE to indicate supported processing times and corresponding communication parameters, and enabling the network to select from multiple options, the system can optimize performance parameters based on current operational requirements.
2Productivity
If UE uses more communication resources, then throughput increases, but processing time requirements increase
Solution Approach 1:
The patent establishes a dynamic relationship between communication resources and processing time. The UE indicates multiple pairs of communication parameters and processing times, allowing the network to dynamically match resource allocation with appropriate processing time requirements. This enables the system to scale resources up when processing time is available and down when latency is critical.
Solution Approach 2:
The patent introduces multiple discrete parameter sets representing different operational modes. Each mode specifies a particular combination of communication resources and processing time, allowing the system to switch between parameter configurations based on current needs rather than being constrained to a single fixed configuration.
3Productivity
If network schedules UE with relaxed timelines, then resource usage increases, but feedback latency increases
Solution Approach 1:
The patent implements dynamic feedback timeline adjustment where the network can schedule the UE with different feedback timelines based on the selected processing time mode. When longer processing times are used to increase resource utilization, the feedback timeline is相应 extended. When shorter processing times are selected for low-latency operations, the feedback timeline is compressed accordingly.
Solution Approach 2:
The patent changes the feedback timeline parameter from a fixed value to a variable that depends on the selected processing time mode. By establishing correspondence between different processing time options and their associated feedback timelines, the system can optimize the balance between resource usage and feedback requirements.

AI summary
Methods, systems, and devices for wireless communication are described. A user equipment (UE) may indicate a first quantity of communication resources associated with a first processing time in which the UE is capable of processing a message that is transmitted over a set of transmission layers using the first quantity of communication resources. The UE may indicate a second quantity of communication resources associated with a second processing time in which the UE is capable of processing a downlink message that is transmitted over the set of transmission layers using the second quantity of communication resources. The UE may receive control signaling, for a scheduled downlink message, that indicates the second quantity of communication resources and that schedules the UE in accordance with the second processing time.
