Full duplex (FD) communication has emerged as an attractive solution for increasing the
network throughput, by allowing downlink (DL) and uplink (UL) transmissions in the same …

This paper exploits the potential of massive multiple input multiple output (MIMO) in K-tier
heterogeneous cellular networks (HCNs), to enhance the data rate for 5G. In such a network …

Massive multiple-input multiple-output (MIMO) is a transmission technique for cellular
systems that uses many antennas to support not-as-many users. Thus far, the performance …

Massive multiple-input multiple-output (MIMO) is a transmission technique for cellular
systems that uses many antennas to support not-as-many users. In this paper, we analyze its …

We propose a time division duplex (TDD) based network architecture where a macrocell tier
with a “massive” multiple-input multiple-output (MIMO) base station (BS) is overlaid with a …

A Cell-Free Massive MIMO (multiple-input multiple-output) system comprises a very large
number of distributed access points (APs), which simultaneously serve a much smaller …

We propose a novel pilot sequence design to mitigate pilot contamination in multi-cell
multiuser massive multiple-input multiple-output networks. Our proposed design generates …

This paper studies a cell-free massive multiple-input multiple-output (MIMO) system where
its access points (APs) and users are equipped with multiple antennas. Two transmission …

Given the recent advances in system and antenna design, practical implementation of full
duplex (FD) communication is becoming increasingly feasible. In this paper, the potential of …

We investigate the heterogeneous cellular network (HetNet) where the macrocell base
stations (MBSs) are equipped with very large antenna arrays. Since such a combined …
