Dynamic UL Slot Allocation for 5G Uplink Bottlenecks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
5G uplink (UL) performance is limited in certain conditions, such as when user equipment (UE) generates significant UL traffic, has limited coverage, engages in mobile edge compute scenarios, or communicates with satellites, leading to bottlenecks that degrade application performance and increase power consumption.
Innovation Solution
UE dynamically increases UL resources by requesting additional slots per frame based on UL traffic conditions, application requirements, and key performance indicators, ensuring UL performance improvement without degrading downlink (DL) performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If UL resources are increased to improve UL performance, then UL throughput and application performance are enhanced, but downlink performance may be degraded due to resource reallocation
Solution Approach 1:
The system dynamically adjusts the number of UL slots per frame based on real-time UL traffic conditions, application requirements, and KPIs. The UE can request additional UL resources when UL traffic increases, and the network can grant these requests by reallocating resources from DL when UL performance needs improvement, creating a dynamic balance between UL and DL performance
Solution Approach 2:
The patent changes the parameter of slots per frame configuration dynamically. The UE determines whether to request additional UL resources based on UL traffic conditions, application UL requirements, current UL resource usage, DL resource usage, and KPIs such as UL throughput, DL throughput, and UL slot share. This parameter change allows the system to adapt resource allocation to varying traffic conditions while maintaining overall system performance
2Productivity
If additional UL resources are allocated to meet application requirements, then UL performance is enhanced, but power consumption increases
Solution Approach 1:
The system uses feedback mechanisms where the UE monitors UL traffic conditions, application requirements, and KPIs to determine when additional UL resources are needed. The UE sends requests to the network based on this feedback, and the network responds by allocating or denying resources. This feedback-driven approach ensures resources are allocated only when necessary, avoiding unnecessary power consumption
Solution Approach 2:
The resource allocation is dynamic rather than static, allowing the system to adjust UL resources based on actual traffic conditions. When UL traffic is low, fewer resources are allocated, reducing power consumption. When UL traffic increases and application performance degrades, the system dynamically increases resources to maintain performance while minimizing overall power consumption
3Productivity
If the number of slots per frame is increased to improve UL throughput, then UL bandwidth is enhanced, but device complexity increases
Solution Approach 1:
The UE autonomously determines when additional UL resources are needed by monitoring UL traffic conditions, application requirements, and KPIs. The UE self-manages the resource allocation process by sending requests to the network when conditions warrant additional resources, reducing the need for complex network-controlled resource management while still achieving optimal UL bandwidth utilization

AI summary
The techniques described herein may include solutions for enabling a user equipment (UE) to monitor uplink (UL) traffic of an application or wireless link, detect an increase in UL traffic, and communicate with a base station, satellite, etc. to dynamically increase UL resources. The increase in UL resource can include a change in the number of UL slots per frame. The UE can determine the UL requirements of the application, assess a current usage of UL resources, verify that downlink (DL) resources are underused, and more. UL performance can be increased without a meaningful decrease in DL performance, as the increase in UL resources can be achieved by a corresponding decrease in DL resources.
