LTE Scheduler for Category 1 M2M Device Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Category 1 M2M devices, which support low peak data rates and do not require MIMO technology, can disproportionately use network resources when transmitting large amounts of data, potentially impacting network service for other devices on an LTE network, necessitating a solution to manage and limit their data transmission effectively.
Innovation Solution
Implementing a scheduler device within the LTE network that generates a resource assignment schedule for category 1 M2M devices, limiting their data rate and ensuring fair allocation of physical resource blocks (PRBs) to prevent network resource overload, while allowing these devices to communicate without affecting other devices' performance.

Engineering Contradiction Analysis
1Productivity
If category 1 M2M devices are allowed to transmit data on the LTE network without restrictions, then these devices can communicate effectively with the core network, but they will disproportionately consume network resources and impact service quality for other devices
Solution Approach 1:
The patent implements dynamic resource allocation by introducing a scheduler that continuously monitors network conditions and adjusts resource assignment for category 1 M2M devices in real-time. The scheduler modifies transmission parameters such as resource block allocation and modulation schemes based on current network load and device performance, enabling adaptive control that prevents resource exhaustion while maintaining effective communication.
Solution Approach 2:
The patent changes key transmission parameters including data rate limits, resource block allocation ratios, and modulation and coding schemes (MCS) specifically for category 1 M2M devices. By imposing data rate ceilings and adjusting resource allocation parameters dynamically, the system ensures these devices can communicate effectively without consuming disproportionate network resources that would impact other devices.
2Ease of operation
If a scheduler is introduced to manage category 1 M2M devices, then fair resource allocation is achieved, but the network complexity increases
Solution Approach 1:
The patent segments the network management function by introducing a dedicated scheduler component that handles category 1 M2M devices separately from other device types. This segmentation allows specialized resource allocation rules and parameters to be applied specifically to M2M traffic, achieving fair resource distribution without requiring complete redesign of the overall network architecture.
Solution Approach 2:
The scheduler implemented in the patent serves multiple functions simultaneously: it performs resource block allocation, monitors data rate compliance, adjusts transmission parameters, and enforces quality of service policies for category 1 M2M devices. By consolidating these functions into a single multi-functional component, the patent achieves comprehensive resource management while minimizing the increase in network complexity.

AI summary
A scheduler device may receive machine-to-machine (M2M) transmission information associated with a data transmission between a base station and a category 1 M2M device. The scheduler device may determine other transmission information associated with the base station. The other transmission information may include information associated with another data transmission between the base station and another device which is not a category 1 M2M device. The scheduler device may generate a resource assignment schedule associated with the category 1 M2M device and the other device. The resource assignment schedule may be based on the M2M transmission information and the other transmission information. The resource assignment schedule may identify a set of resources to be allocated to the category 1 M2M device during an increment of time. The scheduler device may provide the resource assignment schedule.
