Abstract
In the context of sixth-generation (6G) architectures, multiple input multiple output (MIMO) networks emerged with innovative proposals for the future of mobile communications with various applications. Among the many applications, the integration of uncrewed aerial vehicles (UAVs) and ground users (GUEs), combined with the multibeam technique stands out as a powerful alternative for efficiently transmitting and receiving signals. In this article, we study the downlink communication between an access point and a mixture of cellular users, comprised of UAVs and GUEs. The access point employs a multibeam technique to steer beams towards UAVs and GUEs to improve the communication, while also performing power management in the beamforming vectors as a key element. Our results indicate that the variation in the power allocation of the multibeams has a direct impact on the performance of network users. This suggests a wide range of applications in the future prospects for mobile networksDownload
