In this blog post, we introduce the solution proposed by Rimedo Labs: Beamforming Optimization rApp (BO-rApp). We discuss how the BO-rApp can be improved when utilizing location information or a Network Digital Twin - a virtual replica of the network. Then, we point out a possible architecture for the BO-rApp within the O-RAN architecture.  Finally, we present numerical results demonstrating the benefits of the BO-rApp in an event-based scenario.

One approach to realize M-MIMO systems is the GoB concept which relies on a predefined set of beams that are launched in fixed directions. However, the main disadvantage of GoB is that the fixed set of beams may not track the dynamics of a real network, like users' mobility. In some cases, this can lead to QoS degradation. In this blog, we explore how to address this challenge by examining the concept of Beamforming Optimization in the context of its applicability. We present four use cases, with different approaches to the GoB, ranging from static to dynamic beam adaptation.

This blog post covers the topic of Beamforming in the context of the Open Radio Access Network. First, we discuss the possible implementation of beamforming in 5G networks, namely Grid of Beams. Then, some challenges regarding GoB are highlighted. Finally, some ideas for utilizing O-RAN to solve them are mentioned.
