Two-timescale weighted sum-rate maximization for large cellular and cell-free massive MIMO
Lorenzo Miretti, Emil Björnson, Sławomir Stańczak
We reconsider the problem of joint power control and beamforming design to maximize the weighted sum rate in large and potentially cell-free massive MIMO networks. In contrast to t…
Reconfigurable Intelligent Surfaces for 6G Mobile Networks: An Industry R&D Perspective
Maik Sode, Michael Ponschab, Lucas N. Ribeiro +9
The reconfigurable intelligent surface (RIS) technology is a potential solution to enhance network capacity and coverage without significant investment in additional infrastructure…
Unlocking the Potential of Local CSI in Cell-Free Networks with Channel Aging and Fronthaul Delays
Lorenzo Miretti, Sławomir Stańczak
It is generally believed that downlink cell-free networks perform best under centralized implementations where the local channel state information (CSI) acquired by the access-poin…
Optimized Detection with Analog Beamforming for Monostatic Integrated Sensing and Communication
Rodrigo Hernangómez, Jochen Fink, Renato L. G. Cavalcante +2
In this paper, we formalize an optimization framework for analog beamforming in the context of monostatic integrated sensing and communication (ISAC), where we also address the pro…
Towards Bridging the Gap between Near and Far-Field Characterizations of the Wireless Channel
Navneet Agrawal, Ehsan Tohidi, Renato L. G. Cavalcante +1
The "near-field" propagation modeling of wireless channels is necessary to support sixth-generation (6G) technologies, such as intelligent reflecting surface (IRS), that are enable…
QoS prediction in radio vehicular environments via prior user information
Noor Ul Ain, Rodrigo Hernangómez, Alexandros Palaios +2
Reliable wireless communications play an important role in the automotive industry as it helps to enhance current use cases and enable new ones such as connected autonomous driving…
