On the Energy Efficiency of Limited-Backhaul Cell-Free Massive MIMO
Manijeh Bashar, Kanapathippillai Cumanan, Alister G. Burr +3
We investigate the energy efficiency performance of cell-free Massive multiple-input multiple-output (MIMO), where the access points (APs) are connected to a central processing uni…
Massive MIMO for Internet of Things (IoT) Connectivity
Alexandru-Sabin Bana, Elisabeth de Carvalho, Beatriz Soret +4
Massive MIMO is considered to be one of the key technologies in the emerging 5G systems, but also a concept applicable to other wireless systems. Exploiting the large number of deg…
Performance of In-band Transmission of System Information in Massive MIMO Systems
Marcus Karlsson, Emil Björnson, Erik G. Larsson
We consider transmission of system information in massive MIMO. This information needs to be reliably delivered to inactive users in the cell without any channel state information…
Performance Analysis of NOMA in Training Based Multiuser MIMO Systems
Hei Victor Cheng, Emil Björnson, Erik G. Larsson
This paper considers the use of NOMA in multiuser MIMO systems in practical scenarios where CSI is acquired through pilot signaling. A new NOMA scheme that uses shared pilots is pr…
Multigroup Multicast Precoding in Massive MIMO
Meysam Sadeghi, Emil Björnson, Erik G. Larsson +2
Optimal physical layer multicasting (PLM) is an NP-hard problem that for simplicity has been studied under idealistic assumptions, e.g., availability of perfect channel state infor…
Optimal Base Station Design with Limited Fronthaul: Massive Bandwidth or Massive MIMO?
Kamil Senel, Emil Björnson, Erik G. Larsson
To reach a cost-efficient 5G architecture, the use of remote radio heads connected through a fronthaul to baseband controllers is a promising solution. However, the fronthaul links…
