Dynamic Resource Block Access Control for LTE Cat-M1 Noise Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular networks, the use of LTE devices can introduce noise that negatively affects Cat-M1 devices, leading to reduced performance and battery life, as LTE and Cat-M1 share common resources without efficient noise management.
Innovation Solution
An access node dynamically manages resource access by setting a noise threshold, monitoring noise parameters, and restricting access to resource blocks for communication modes based on noise levels, ensuring efficient allocation and reducing interference.

1Productivity
If LTE devices share common resource blocks with Cat-M1 devices, then resource utilization is improved, but noise interference increases and Cat-M1 performance deteriorates
Solution Approach 1:
The patent implements dynamic determination of common resource block access for Cat-M1 devices based on real-time noise parameter measurements. The access node continuously monitors noise levels and dynamically adjusts whether Cat-M1 devices can access common resource blocks, transitioning between shared and restricted access modes according to current interference conditions.
Solution Approach 2:
The system changes the operational parameters of resource block allocation based on noise threshold comparisons. When noise parameters exceed predetermined thresholds, the system modifies the access conditions for Cat-M1 devices on common resource blocks, effectively using parameter-based control to manage interference while maintaining resource utilization efficiency.
2Productivity
If LTE communication occurs on shared resources, then network capacity is improved, but Cat-M1 device battery life is reduced due to increased noise
Solution Approach 1:
The access node implements a feedback mechanism by monitoring noise parameters on common resource blocks and using this information to dynamically control Cat-M1 device access. This closed-loop feedback system ensures that Cat-M1 devices only access shared resources when noise levels are acceptable, thereby protecting battery life while allowing network capacity utilization when conditions permit.
3Productivity
If common resource blocks are shared between LTE and Cat-M1, then resource efficiency is improved, but access control complexity increases
Solution Approach 1:
The access node serves as an intermediary that manages the complexity of resource block allocation. It implements a standardized procedure for determining Cat-M1 access to common resource blocks based on noise parameter comparisons, effectively mediating between LTE and Cat-M1 devices and simplifying the overall access control mechanism through centralized decision-making.

AI summary
A system and method of managing network resources is provided, in which a noise threshold for an access node is set, the access node including a first plurality of resource blocks corresponding to communication in a first communication mode and a second plurality of resource blocks corresponding to communication in either of the first communication mode or a second communication mode; a noise parameter for the second plurality of resource blocks is monitored; the noise parameter is compared to the noise threshold; and in response to a determination that the noise parameter exceeds the noise threshold, access to the second plurality of resource blocks for communication in the first communication mode is restricted.
