Uplink Grant Scheduling for Delayed Data Availability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-dedicated access networks, such as cable television access networks, often experience significant uplink latency and inefficiencies due to delays in data availability and waste of transmission capacity at wireless base stations, which are not adequately addressed by existing technologies.
Innovation Solution
Implementing a system where the wireless base station predicts the amount of data to be transmitted and generates a signal based on a delay profile to optimize data transmission, allowing for just-in-time transfer and reducing latency by generating grants that align with the anticipated data availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If non-dedicated access networks are used to provide backhaul link connections, then installation cost and infrastructure requirements are reduced, but uplink latency and data availability delay increase
Solution Approach 1:
The base station predicts the amount of data to be transmitted and generates a signal representing anticipated upcoming data transmission before the data is actually ready for transfer. This preliminary action allows the network to prepare transmission resources in advance, mitigating the latency inherent in non-dedicated access networks.
2Ease of manufacture
If non-dedicated access networks are used to provide backhaul link connections, then installation cost and infrastructure requirements are reduced, but transmission capacity waste increases
Solution Approach 1:
The system uses a delay profile representing delay in data availability at the base station to adjust the predicted amount of data. This feedback mechanism allows the network to dynamically allocate transmission capacity based on actual data availability patterns, reducing waste while using cost-effective non-dedicated access networks.
3Speed
If data is transferred immediately when available in non-dedicated access networks, then data transmission speed is maintained, but transmission capacity is wasted due to mismatched timing
Solution Approach 1:
Instead of waiting for data to be ready and then initiating transfer, the system performs preliminary actions by predicting future data transmission needs and signaling the network in advance. This allows transmission capacity to be reserved and prepared beforehand, ensuring immediate transfer when data becomes available without wasting capacity on premature or mismatched transmission attempts.

AI summary
A method for mitigating delay in availability of data in a communication network includes predicting an amount of data to egress a first communication device; modifying the predicted amount of data to egress the first communication device according to a data delay profile, to generate a first signal representing anticipated upcoming data transmission by the first communication device, where the data delay profile represents delay in availability of data at the first communication device; transmitting the first signal from the first communication device to the second communication device; generating one or more Grants at the second communication device at least partially in accordance with the first signal, each Grant authorizing the first communication device to transfer data via the network; and transmitting the one or more Grants from the second communication device to the first communication device.
