Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellular communication systems lack efficient methods for prioritizing downlink data transmissions based on various attributes, leading to suboptimal user experience and network performance, especially in multi-user and multi-technology environments.
Innovation Solution
Implementing network-based and sender-based data packet prioritization techniques using machine learned models to tag data packets with priority levels based on attributes such as application type, user preferences, and network conditions, allowing for optimized transmission through the radio protocol stack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data packets are transmitted without prioritization in current cellular systems, then the system operation is simple, but the Quality of Service and user experience deteriorate in multi-user environments
Solution Approach 1:
The patent applies preliminary action by tagging data packets with priority levels before transmission. The sender device (user equipment or base station) classifies and marks packets with QoS parameters in advance, allowing the network to prioritize transmission without adding complex real-time decision-making infrastructure. This pre-tagging approach enables differentiated service quality while maintaining relatively simple system operation.
2Productivity
If priority tagging is implemented at the sender device, then transmission optimization is achieved, but the processing complexity at the sender increases
Solution Approach 1:
The patent applies partial action by implementing priority tagging only where needed - either at the user equipment for uplink traffic or at the base station for downlink traffic. Not all devices must implement the full functionality, allowing systems to gain transmission optimization benefits while limiting the processing complexity increase to only those components that require it.
3Adaptability or versatility
If multiple priority levels are assigned to data packets, then Quality of Service differentiation is improved, but the complexity of packet management increases
Solution Approach 1:
The patent applies parameter changes by using standardized QoS parameters (5QI for 5G, QCI for 4G) that encode priority information in predefined values. Instead of creating complex custom priority schemes, the system leverages existing parameter frameworks with defined mappings between parameter values and priority levels. This enables versatile service differentiation while keeping packet management complexity manageable through standardized parameter interpretation.

AI summary
Techniques for network-based and sender-based data packet prioritization for downlink transmissions are discussed herein. Packets can be tagged or associated with information indicative of a priority of the packet for downlink transmission to a user equipment (UE). A priority level can be determined based on an application identifier or type associated with a data request, a level of user interaction with the UE, network conditions, and other factors. Packets can be received by a PDCP layer of a base station for sending based on the priority. Packets may be associated with a primary priority level associated with a QCI level and a secondary priority level based on UE and/or network factors discussed herein. Packets associated with a same QCI may be prioritized to optimize transmission of downlink data associated with a single UE or between transmission of downlink data associated with a plurality of UEs.
