Welcome to Session 14 of our Open RAN series! In this session, we&#39;ll introduce supervised machine learning and its application in designing intelligent systems for Open RAN.&#60;br/&#62;&#60;br/&#62;&#60;br/&#62;Understanding Supervised Machine Learning:&#60;br/&#62;Supervised machine learning is a type of machine learning where the algorithm learns from labeled data. It involves training a model on a dataset that contains input-output pairs, where the input is the data and the output is the corresponding label or target variable. The algorithm learns to map inputs to outputs by finding patterns in the data. In Open RAN, supervised learning can be used for tasks such as predicting network performance based on historical data.&#60;br/&#62;&#60;br/&#62;Types of Supervised Machine Learning:&#60;br/&#62;There are two main types of supervised machine learning: classification and regression. In classification, the algorithm learns to categorize data into predefined classes or categories. For example, it can classify network traffic into different application types (e.g., video streaming, web browsing). Regression, on the other hand, involves predicting continuous values or quantities. It is used when the output variable is a real or continuous value, such as predicting the signal strength of a network connection.&#60;br/&#62;&#60;br/&#62;Binary and Multi-Class Classification:&#60;br/&#62;Binary classification involves categorizing data into two classes or categories. For example, it can be used to classify network traffic as either malicious or benign. Multi-class classification, on the other hand, involves categorizing data into more than two classes. It can be used to classify network traffic into multiple application types (e.g., video streaming, social media, email).&#60;br/&#62;&#60;br/&#62;Regression in Machine Learning:&#60;br/&#62;Regression is a supervised learning technique used for predicting continuous values or quantities. It involves fitting a mathematical model to the data, which can then be used to make predictions. In Open RAN, regression can be used for tasks such as predicting network latency, throughput, or coverage based on various input variables such as network parameters, traffic patterns, and environmental conditions.&#60;br/&#62;&#60;br/&#62;Subscribe to &#92;

Introduction:&#60;br/&#62;In this session, we&#39;ll introduce the RAN Intelligent Controller (RIC) and explore its role in enhancing network capabilities. We&#39;ll also discuss two examples highlighting the use of RIC in Open RAN scenarios.&#60;br/&#62;&#60;br/&#62;Introduction to RIC:&#60;br/&#62;The RAN Intelligent Controller (RIC) is a key component in Open RAN architecture, providing intelligent control and optimization capabilities to the RAN. RIC can be classified into Near Real-Time RIC (NRT-RIC) and Non-Real-Time RIC (Non-RT-RIC), each serving specific functions within the network.&#60;br/&#62;&#60;br/&#62;Example 1: RAN Slice for Enterprise Customer:&#60;br/&#62;We&#39;ll illustrate how NRT-RIC and Non-RT-RIC can facilitate the creation of RAN slices to cater to enterprise customers. For instance, consider an enterprise customer who has subscribed to services guaranteeing 50Mbps throughput for their users using various XAPPs (e.g., XRAN, XHSS, etc.). NRT-RIC can dynamically allocate resources and prioritize traffic in near real-time to meet the throughput requirements of these XAPPs, ensuring a reliable and high-performance connection for enterprise users. On the other hand, Non-RT-RIC can perform more complex and resource-intensive optimization tasks that do not require immediate action, such as long-term network planning and policy configuration.&#60;br/&#62;&#60;br/&#62;Example 2: Power Control using RIC Apps (RApps):&#60;br/&#62;We&#39;ll discuss another example focusing on power control using RIC Apps (RApps). RIC can leverage RApps to manage power usage in the RAN, optimizing energy consumption without compromising network performance. For instance, RIC can dynamically adjust transmit power levels based on traffic load and coverage requirements, leading to more efficient power utilization across the network.&#60;br/&#62;&#60;br/&#62;Conclusion:&#60;br/&#62;RIC plays a crucial role in enabling dynamic and intelligent control of the RAN, offering significant benefits in terms of performance optimization, resource allocation, and energy efficiency.
