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…
Device Activity and Embedded Information Bit Detection Using AMP in Massive MIMO
Kamil Senel, Erik G. Larsson
Future cellular networks will support a massive number of devices as a result of emerging technologies such as Internet-of-Things and sensor networks. Enhanced by machine type comm…
Random Pilot and Data Access in Massive MIMO for Machine-type Communications
Elisabeth de Carvalho, Emil Björnson, Jesper H. Sørensen +2
A massive MIMO system, represented by a base station with hundreds of antennas, is capable of spatially multiplexing many devices and thus naturally suited to serve dense crowds of…
