Energy Efficient Downlink Transmission for Multi-cell Massive DAS with Pilot Contamination
, 2016 In this paper, we study the energy efficiency (EE) of a downlink multi-cell massive distributed antenna system (DAS) in the presence of pilot contamination (PC), where the antennas are clustered on the remote radio heads (RRHs).

Scalable Cell-Free Massive MIMO With Indoor/Outdoor Users
IEEE Open Journal of Vehicular TechnologyCell-free networks are expected to be a forthcoming (r)evolutionary step in the coming generation of mobile networks, the so called 6 G. While mobile infrastructure is often assumed to be deployed outdoor by the operators, reality is that most of the ...

6DMA-Aided Cell-Free Massive MIMO Communication
IEEE Wireless Communications LettersIn this letter, we propose a six-dimensional movable antenna (6DMA)-aided cell-free massive multiple-input multiple-output (MIMO) system to fully exploit its macro spatial diversity, where a set of distributed access points (APs), each equipped with multiple 6DMA surfaces, cooperatively serve all users in a given area. Connected to a central processing
