Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication networks face challenges in efficiently managing shared radio resources, particularly when Cat-M1 transmissions are high while NR and LTE demands are low, leading to suboptimal resource utilization and capacity limitations.
Innovation Solution
A method implemented by a network node to estimate first technology resource usage for bandwidth-limited transmissions like Cat-M1, and adjust priority orders dynamically based on predefined criteria to favor second technology transmissions such as LTE and NR, ensuring optimal resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Cat-M1 transmissions are prioritized to ensure high capacity for bandwidth-limited devices, then Cat-M1 resource utilization is improved, but resource availability for NR and LTE transmissions deteriorates
Solution Approach 1:
The patent implements dynamic priority adjustment for Cat-M1 transmissions based on real-time resource utilization thresholds. When estimated Cat-M1 resource usage exceeds predefined thresholds, the priority order is dynamically changed from high to low, allowing the system to adapt resource allocation between Cat-M1, NR, and LTE transmissions according to current network conditions
Solution Approach 2:
The system changes the priority order parameter for Cat-M1 transmissions based on resource utilization conditions. By modifying this scheduling parameter dynamically, the network can shift resource allocation between different transmission types (Cat-M1, NR, LTE) to optimize overall network performance while preventing any single technology from monopolizing shared radio resources
2Productivity
If dynamic priority adjustment is implemented to favor NR and LTE during high demand, then resource efficiency is improved, but system complexity increases
Solution Approach 1:
The patent employs feedback mechanisms where the network node continuously estimates Cat-M1 resource usage and compares it against predefined thresholds. Based on this feedback loop, the system automatically adjusts priority orders for upcoming Cat-M1 transmissions, enabling intelligent resource management without requiring complex manual configuration or intervention
Solution Approach 2:
The network node performs self-service by autonomously estimating resource usage, evaluating threshold conditions, and adjusting priority orders without external control. This self-managing capability allows the system to optimize resource allocation between Cat-M1, NR, and LTE transmissions independently, reducing the need for complex external management systems

AI summary
A method performed by a network node is provided. The method is for handling radio resources for an upcoming first technology transmission between the network node and a first technology device in a wireless communications network. The radio resources are shared between first technology transmissions and second technology transmissions. The first technology transmissions relate to transmissions that are bandwidth limited. The second technology transmissions relate to any one or more out of: Long Term Evolution, LTE, and New Radio, NR, transmissions. The network node estimates (203) first technology resources used for first technology transmissions in a shared radio resource. The network node determines (204) whether or not one or more criteria related to the estimated first technology resources are fulfilled. When the one or more criteria are fulfilled, the network node adjusts (205) a priority order for the upcoming first technology transmission to be lower than a given priority order in the radio resource to be shared. The adjusted priority order is in favour for the second technology transmissions. When the one or more criteria are not fulfilled. the network node keeps (206) the given specific priority order for the upcoming first technology transmission in the radio resource to be shared.
