Uplink Signaling Sequence Codes for Latency and Resource Trade-offs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication systems face challenges in managing bursty traffic patterns, particularly in uplink transmissions, where pre-allocating resources for signaling requests leads to either high latency or inefficient resource allocation, affecting user experience and quality of service.
Innovation Solution
A method involving a sequence of codes shared among multiple user equipment (UEs) is used to request uplink resources, where the network element allocates minimal initial resources and dynamically allocates further resources based on received codes, allowing efficient scheduling and reducing waste while meeting latency bounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the number of pre-allocated uplink request slots or resources is increased, then the latency for devices to request uplink resources is reduced, but the number of resources available for transmitting mobile user traffic decreases
Solution Approach 1:
The patent segments the resource allocation process into two distinct phases: a minimal pre-allocation phase where only a small number of uplink request slots are reserved, and a dynamic allocation phase where additional resources are allocated on-demand based on actual traffic needs. This segmentation allows the system to maintain low latency for requests while preserving the majority of resources for user traffic transmission.
Solution Approach 2:
The patent implements dynamic resource allocation where the network element monitors traffic patterns and adjusts resource allocation in real-time. Instead of static pre-allocation, the system dynamically assigns additional uplink request slots to specific devices based on their actual traffic demands, ensuring that resources are available when needed without permanently reserving excessive resources.
2Quantity of substance
If the number of pre-allocated uplink request slots or resources is reduced, then more resources are available for transmitting mobile user traffic, but the waiting time for devices to request uplink resources increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring a minimal set of uplink request slots and establishing the dynamic allocation framework in advance. This preliminary setup ensures that the basic mechanism for low-latency requests is in place, while the actual resource expansion happens dynamically based on need, thus maintaining both low waiting time and high resource efficiency.
Solution Approach 2:
The patent employs feedback mechanisms where the network element continuously monitors uplink traffic requests and device buffer status. This feedback information is used to dynamically adjust resource allocation, ensuring that resources are allocated promptly when devices need them, thereby minimizing waiting time without requiring excessive pre-allocation.
3Productivity
If more resources are pre-allocated for monitoring uplink requests, then the latency for servicing requests is reduced, but the resource utilization efficiency decreases
Solution Approach 1:
The patent enables a self-service mechanism where devices that have actual uplink traffic needs actively indicate their requirements through the minimal pre-allocated request slots. The network element then provides targeted resource allocation only to those devices that need service, eliminating the waste of monitoring and allocating resources to devices with no traffic, thus improving both servicing speed and efficiency.
