Wireless Slot Allocation for Throughput Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently allocating communication bandwidth to maximize throughput without exceeding the capacity of backhaul links or network elements, particularly in scenarios where devices operate with varying modulation and coding schemes and RF conditions.
Innovation Solution
A method where base stations receive indicators of throughput for network elements and allocate slots to wireless devices based on their associated modulation and coding schemes, prioritizing devices with lower throughput rates and those in poor RF conditions to ensure total traffic does not exceed the maximum capacity, thereby optimizing bandwidth allocation and reducing interference.

Engineering Contradiction Analysis
1Productivity
If slots are allocated to maximize throughput for wireless devices, then data transmission efficiency is improved, but the total throughput may exceed the maximum capacity of backhaul links or network elements
Solution Approach 1:
The base station receives an indicator of throughput for network elements and uses this feedback information to adjust slot allocation. The indicator provides real-time information about network capacity, allowing the base station to dynamically modify throughput requests from wireless devices to ensure total throughput remains within maximum capacity constraints while maximizing data transmission efficiency.
Solution Approach 2:
The system changes the throughput parameter for wireless devices based on network conditions. By adjusting the throughput parameter dynamically according to the indicator received from network elements, the base station optimizes the balance between maximizing data transmission efficiency and preventing capacity overload on backhaul links.
2Productivity
If slot allocation prioritizes devices with higher throughput rates, then overall data transmission efficiency is improved, but devices in poor RF conditions receive insufficient resources
Solution Approach 1:
The base station applies different slot allocation strategies to different wireless devices based on their local conditions. Devices in poor RF conditions receive prioritized treatment compared to devices in good RF conditions, ensuring that each device receives appropriate resources according to its specific operational environment rather than applying uniform allocation rules.
Solution Approach 2:
Instead of prioritizing devices with naturally better throughput capabilities, the system inverts the priority logic by favoring devices with lower throughput rates and those in poor RF conditions. This inversion ensures that resources are allocated to devices that need them most, improving overall network coverage while still maintaining efficiency.
3Reliability
If more slots are allocated to devices in poor RF conditions, then network coverage is enhanced, but total air interface resources consumed increase
Solution Approach 1:
The base station applies partial prioritization to devices in poor RF conditions rather than providing excessive resources to all devices uniformly. By applying the prioritization principle selectively only to devices that meet the criteria (poor RF conditions, lower throughput rates), the system enhances network coverage for these devices while avoiding unnecessary consumption of air interface resources from devices that do not require such preferential treatment.
