A Comparison between Network-Controlled Repeaters and Reconfigurable Intelligent Surfaces
Hao Guo, Charitha Madapatha, Behrooz Makki +4
Network-controlled repeater (NCR) has been recently considered as a study-item in 3GPP Release 18, and the discussions are continuing in a work-item. In this paper, we introduce th…
Positioning and Sensing in 6G: Gaps, Challenges, and Opportunities
Ali Behravan, Vijaya Yajnanarayana, Musa Furkan Keskin +8
Among the key differentiators of 6G compared to 5G will be the increased emphasis on radio based positioning and sensing. These will be utilized not only for conventional location-…
Integrated Access and Backhaul in Cell-free Massive MIMO Systems
Ali Hosseinalipour Jazi, S. Mohammad Razavizadeh, Tommy Svensson
One of the major challenges with cell-free (CF) massive multiple-input multiple-output (MIMO) networks is providing backhaul links for a large number of distributed access points (…
Constrained Deployment Optimization in Integrated Access and Backhaul Networks
Charitha Madapatha, Behrooz Makki, Hao Guo +1
Integrated access and backhaul (IAB) is one of the promising techniques for 5G networks and beyond (6G), in which the same node/hardware is used to provide both backhaul and cellul…
Electromagnetic Field Exposure Avoidance thanks to Non-Intended User Equipment and RIS
Hao Guo, Dinh-Thuy Phan-Huy, Tommy Svensson
On the one hand, there is a growing demand for high throughput which can be satisfied thanks to the deployment of new networks using massive multiple-input multiple-output (MIMO) a…
6G Radio Requirements to Support Integrated Communication, Localization, and Sensing
Henk Wymeersch, Aarno Pärssinen, Traian E. Abrudan +10
6G will be characterized by extreme use cases, not only for communication, but also for localization, and sensing. The use cases can be directly mapped to requirements in terms of…
Dynamic Blockage Pre-Avoidance using Reconfigurable Intelligent Surfaces
Hao Guo, Behrooz Makki, Magnus Åström +2
Internet-of-vehicle (IoV) is a general concept referring to, e.g., autonomous drive based vehicle-to-everything (V2X) communications or moving relays. Here, high rate and reliabili…
