File Batch Scheduling for Wireless XR Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems, particularly those supporting extended reality (XR) applications, face challenges in managing high data rate requirements and tight delay budgets due to the lack of effective methods for scheduling and resource allocation for batches of packets that need to be processed together as files, leading to inefficiencies and reliability issues.
Innovation Solution
User equipment (UE) in these systems identifies packets configured to be processed as files, performs resource management by determining transmission direction schedules, grants, and decoding candidates, and adjusts transmission power to ensure reliable communication of file batches, using configured grants and preemption indications to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packet scheduling methods are used for XR applications, then individual packets can be transmitted independently, but the reliability of file batch processing deteriorates because packets that need to be processed together may not be received successfully as a complete set
Solution Approach 1:
The patent merges multiple packets that need to be processed together into a single file batch unit. By treating these packets as a combined entity with a shared success/failure outcome, the system ensures that either all packets in the batch are successfully received or none are, thereby maintaining file processing reliability without requiring complex individual packet scheduling coordination
Solution Approach 2:
The patent applies preliminary action by pre-configuring file batch parameters including the total number of packets, packet size, and success criteria before transmission begins. This advance configuration allows the scheduling system to manage file batches as predefined units with known requirements, simplifying real-time scheduling decisions while ensuring reliability
2Productivity
If resource management is optimized for individual packets, then transmission efficiency for single packets improves, but the efficiency of file batch communication deteriorates due to lack of coordinated resource allocation for packets that must be processed together
Solution Approach 1:
The patent combines resource allocation decisions for multiple packets into a single file batch-level allocation. By assigning resources to the entire file batch rather than individually to each packet, the system achieves coordinated resource management that improves communication efficiency while ensuring all packets receive adequate resources for successful transmission
Solution Approach 2:
The patent creates a universal resource allocation mechanism that can handle both individual packet transmission and file batch processing through a unified framework. The file batch configuration and resource management system serves multiple functions including coordination, allocation, and success criterion enforcement, thereby improving overall efficiency without sacrificing reliability
3Loss of information
If transmission scheduling is performed for each packet individually, then scheduling flexibility is maintained, but signaling overhead increases due to separate scheduling messages for each packet in the file batch
Solution Approach 1:
The patent merges multiple individual packet scheduling messages into a single file batch scheduling message. By transmitting scheduling information at the file batch level rather than for each individual packet, the system significantly reduces signaling overhead while maintaining the ability to schedule and track each packet within the batch through the unified file batch configuration

AI summary
Methods, systems, and devices for wireless communications are described. Devices of a wireless communications system may be configured to group data packets as a batch or file. In some cases, resources may be determined based on one or more resource grants corresponding to file communication. Other aspects may include DCI configurations corresponding to file communication, resource grants may be configured to assign resources for communication of a file. For example, a DCI may be specifically configured for granting resources for communication of a file. In another example, configured grants may include a configured grant index corresponding to communication of a file. Other aspects may include configuration of a UE for responding to a preemption indication when a file is scheduled for communication, power adjustments for communication of a file, reference signal configurations for communication of a file, and/or coherent detection/transmission across two or more packets of a file.
