| SORUS-RAN-A1.2-E1 | vRAN Use Cases | This document corresponds to deliverable A1.2 - VRAN Use Cases - which is in the initial phase of the tasks described in the technical specifications. It describes three relevant vRAN use cases and studies the parameters of interest to optimize, the metrics to consider, and the different optimization objectives. Following the introduction, the primary goal is to identify scenarios where vRAN virtualization is an advantage over existing deployments. The deployment of multiple virtualized O-DUs on shared computing nodes is studied, as well as the advantages, disadvantages, and challenges of deploying different virtualized O-DUs on the same platform. The technical challenges of deploying multiple O-DUs at the computational level and shared hardware acceleration, as well as associated AI services at the Edge, are also described. The use of both Non-Real Time and Near-Real Time controllers is analyzed to improve resource allocation based on demand. |
| SORUS-RAN-A2.1-E1 | Initial vRAN Profiling | This document corresponds to deliverable A2.1 - vRAN Profiling - which is in the initial phase of the tasks described in the technical specifications. This document defines the elements used in the implementation of two testbeds to conduct various experiments aimed at obtaining energy consumption data. These data include both CPU and device consumption, allowing for separate comparison of energy consumption under the use cases outlined in the SORUS-RAN-A1.2 document. This has made it possible to appreciate, in terms of energy consumption reduction, that the hardware platform used plays a fundamental role in the total consumption, making it essential to select the appropriate platform based on the needs. At the same time, finding the right balance of MCS, airtime, and image resolution (if applicable) in each situation is essential to reduce energy consumption without compromising the end-user experience. |
| SORUS-RAN A2.1-E2 | Final vRAN Profiling | This document summarizes the existing features in vRAN environments and solutions through the proposed O-RAN architecture, which includes both non-real-time and near-real-time intelligent radio control. The problem of noisy neighbors is mainly addressed in this type of deployments with resource sharing. An experimental platform based on Docker is presented with which different experiments have been carried out to find the main reason for the exponential performance degradation with the increase of vBS. It has been concluded that secure computing weakly affects this increase (7%) and context switches account for 43% of the total overhead. However, the main problem lies in cache losses, which increase by 500% with five vBS. |
| SORUS-RAN-A2.2-E1 | First version of joint optimization algorithms | This deliverable deals with algorithms created for the optimisation of IoT networks to provide low-cost, high-bandwidth connectivity. For this purpose, an algorithm based on reconfigurable intelligent surfaces (RISs), called RISMA, has been developed, which jointly optimises the RIS parameters and the beamforming strategy at the transmitter from a theoretical perspective. In turn, an algorithm developed from the previous one, called Lo-RISMA, is presented, which aims to provide a solution to the cases where low resolution RISs are used through the study of the standarized mean square error (SMSE) to achieve an optimisation of the aggregate transmission rate of the system in the downlink. |

This document presents a preliminary study of the technology and technical feasibility necessary to address the challenge of improving wireless networks through the use of reconfigurable smart surfaces. Three main areas of improvement have been defined: connectivity and reliability, localization and detection, and sustainability and security. It theoretically describes how this technology can be useful to overcome problems in urban environments with high density of obstacles or without direct line of sight from the base stations (BSs). In indoor and outdoor environments, it could be used for people detection as a passive radar or environment mapping. Regarding security, it can enable highly directional communications, resulting in greater energy efficiency and preventing signal interception by other agents. |

After describing the environment, our focus will shift to analyzing radio access technologies (3G, 4G, 5G, and Wi-Fi) and their impact on energy consumption. Subsequently, we will outline the planned experiments for the upcoming Deliverable 2. Finally, from Telefónica's perspective as a connectivity provider, we will explore the energy-saving mechanisms of base stations when entering different suspension patterns. These results will be presented in Deliverable 3. |
| SORUS-RIS-A2.1-E2 | Experiment Design and Development | In the field of telecommunications, understanding the energy consumption of smartphones is a critical area of focus. With approximately 8 billion smartphones in use worldwide, examining how these devices consume energy during internet use can highlight opportunities for significant improvements and optimizations. Despite its importance, this area remains relatively unexplored by researchers. Our goal is to identify the main factors contributing to the increased energy consumption in smartphones during internet use. To achieve this, we have concentrated on key elements such as content size, radio access technologies (3G, 4G, 5G, WiFi), device age (newer vs. older models), mobile network operators (e.g., Vodafone, Movistar), and types of applications (web browsers, social networks, video streaming). By identifying these factors, we aim to uncover insights that can drive more efficient energy use in smartphones. |

These include the identification of the psychological and behavioural concepts of relevance for the characterization of users’ response to the system latency, as well as the identification of the methodology to be used for its measurement. Furthermore, this Deliverable presents the first version of the user classification algorithm, applied to three different datasets, as well as the results of the pilot study based on the use of psychophysiological signals, as a first step for the integration of these in the classification algorithm. |
| SORUS-RIS-A3.1-E1 | RIS Simulator Design | This report represents a preliminary investigation into the benefits of incorporating RIS (Reconfigurable Intelligent Surface) equipment into Radio Access networks (RAN) to enhance cellular services. To conduct this evaluation, it is necessary to design a system-level simulator capable of capturing both realistic propagation environments and the behavior of RIS. In this work, we have designed such a simulator using the Remcom Wireless InSite ray-tracing tool, an advanced commercial software for radio-level analysis. Our goal is to augment the capabilities of this tool to aid in the deployment and simulation of RIS, featuring specific radiation patterns derived from laboratory test bench environments. We aim to assess the impact of RIS repeaters on radio coverage improvement, taking into account key system parameters such as size, location, and orientation. |
| SORUS-RIS-A3.2-E1 | Platform design | This document includes the requirements imposed to achieve a passive, scalable and sustainable RIS. In contrast to other works, a RIS design is proposed with modularity features and capable of offering 3-bit resolution, which enables high spatial resolution codebooks. A RIS design is proposed using an RF switch, which reduces the cost of controlling the reflector cells with respect to PIN diode-based solutions, and the use of two buses called cell selection and phase selection buses, which enable scalability. |
