PDU Set Transmission with Minimum-Packet Resource-Saving Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in resource utilization when transmitting PDU sets for extended reality applications, as they often transmit all packets despite the application only needing a minimum subset for functionality, leading to unnecessary resource consumption.
Innovation Solution
Implementing a resource-saving mode where transmitting devices evaluate PDU sets based on predefined conditions to determine if essential packets have been delivered, allowing for the proactive discarding of non-essential packets, configured per data radio bearer or QoS flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all packets in a PDU set are transmitted to ensure complete data delivery, then reliability of data transmission is improved, but network resource consumption increases
Solution Approach 1:
The patent extracts and transmits only the essential subset of packets from the PDU set that are necessary for XR application functionality, rather than transmitting all packets. This is achieved by identifying and marking essential packets during PDU set construction, then selectively transmitting only those packets that meet the minimum requirement for application operation, thereby reducing network resource consumption while maintaining reliability.
Solution Approach 2:
The patent applies partial action by transmitting a partial subset of packets (only the essential portion) rather than the complete PDU set. The system determines the minimum number of packets required for XR application functionality and transmits only that partial amount, avoiding the excessive transmission of non-essential packets that would consume additional network resources.
2Loss of information
If all packets in a PDU set are transmitted to ensure complete data delivery, then information completeness is improved, but network overhead increases
Solution Approach 1:
The patent extracts only the essential information-carrying packets from the PDU set for transmission. By identifying essential packets during PDU set construction and selectively transmitting only those, the system maintains information completeness sufficient for XR application functionality while reducing the quantity of transmitted data and associated network overhead.
Solution Approach 2:
The patent transmits a partial subset of packets containing the minimum essential information required for XR application operation. This partial transmission approach maintains adequate information completeness for application functionality while minimizing network overhead by excluding non-essential packets.
3Productivity
If a minimum subset of packets is transmitted to save resources, then network resource efficiency is improved, but risk of incomplete data delivery increases
Solution Approach 1:
The patent performs preliminary identification and marking of essential packets during PDU set construction, before transmission. This preliminary action ensures that the selected subset of packets contains all necessary information for XR application functionality, thereby maintaining reliability while improving network resource efficiency through selective transmission.
Solution Approach 2:
The system performs self-service by autonomously determining which packets are essential for XR application functionality and selecting them for transmission without requiring external intervention or complete transmission of all packets. This self-service approach ensures adequate data delivery completeness while optimizing network resource efficiency.

AI summary
A wireless device is configured to transmit a protocol data unit (PDU) set. The wireless devices receives a configuration of a resource-saving mode in which the wireless device is allowed to discard, when a minimum requirement for delivering the PDU set is satisfied, one or more packets of the PDU set. The wireless device determines information to evaluate the minimum requirement for delivering the PDU set and processes the PDU set for transmission, When the minimum requirement for delivering the PDU set is satisfied, based on the information, the wireless device determines that the PDU set is successfully delivered and discards any unsent packets of the PDU set.
