Seamless integration of efficient 6G wireless technologies for communication and Sensing

6 G-SENSES提出了新的6 G RAN技术的集成，例如无小区（CF）大规模多输入多输出（MIMO）和联合通信和感知（JCAS），以支持基于3GPP和O-RAN的当前（和未来）架构框架所支持的6 G愿景。该项目考虑了一个多技术RAN生态系统，其技术能够提供传感功能。这些技术包括Sub-6、Wi-Fi、毫米波和5G NR，它们将共存于JCAS框架中，其目标是从周围环境中检索尽可能多的信息，以提高能源效率、降低功耗并支持高数据速率的通信。此外，这些技术中的一些将适合于集成在使用毫米波和Sub-6技术的完全分布式CF-mMIMO方案的第一实现中。为了提高可用性和覆盖范围，并提高传感性能，将利用可重新配置的智能表面（RIS），利用接入点的分布式特性和多天线的可用性。提出了一种适合于RIS辅助CF网络结构的分布式信号处理和资源分配方案的优化方法。该框架将利用新的PHY技术来增加接入点之间的合作及其固有能力，以提高感测能力的精度/准确度。来自这些技术的感测信息将被推送到O-RAN framweork，以使用无线电智能控制器（RIC）进行优化。总共将展示三个概念验证演示，其中包括在单个基础设施中的项目的拟议目标

6G-SENSES proposes the integration of novel 6G RAN technologies such as Cell-Free (CF) Massive Multiple-Input Multiple-Output (MIMO) and Joint Communication and Sensing (JCAS) to support the 6G vision that is sustained by the current (and future) architectural framework based on 3GPP and O-RAN. The project considers a multi-technology RAN ecosystem with technologies that are able to offer sensing functionalities. These technologies are Sub-6, Wi-Fi, millimeter wave and 5G NR, which will coexist in a JCAS framework whose goal is to retrieve as much information as possible from the surrounding environment to improve energy efficiency, reduce power consumption and favour communication at high data rates. Additionally, some of these technologies will be amenable to be integrated in the first implementation of a fully distributed CF-mMIMO scheme using mmWave and Sub-6 technologies. WIth the aim to enhance availability and coverage and to improve sensing performance, will leverage Reconfigurable Intelligent Surfaces (RISs) making use of the distributed nature of the access points and availability of multiple antennas. An optimization of distributed signal processing and resource allocation schemes tailored for RIS-assisted CF network architecture is proposed. This framework will make use of new PHY technologies to increase the cooperation among access points and their inherent capabilities to improve the precision/accuracy of the sensing capabilities. Sensing information stemming from these technologies will be pushed to the O-RAN framweork for optimization purposes using the Radio Intelligent Controllers (RICs). A total of three Proof-of-Concept demonstrations will be showcased, which encompass the proposed objectives of the project in a single infrastructure
