A Fine-Grained Analysis of Millimeter-Wave Device-to-Device Networks

open access: yesIEEE Transactions on Communications, 2017
Enabling device-to-device (D2D) communications in millimeter-wave (mm-wave) networks is of critical importance for the next-generation mobile networks to support very high data rates (multi-gigabits-per-second) for mobile devices. In this paper, we provide a fine-grained performance analysis of the mm-wave D2D communication networks.

Millimeter-Wave Device-to-Device Networks With Heterogeneous Antenna Arrays

open access: yesIEEE Transactions on Communications, 2018
Millimeter-wave (mm-wave) device-to-device (D2D) communication is considered one of the most promising enabling technologies to meet the demanding requirements of future networks. Previous works on mm-wave D2D network analysis mostly considered the case that all devices were equipped with exactly the same number of antennas, whereas real networks are ...
