Abstract

Future wireless multiple-input multiple-output
(MIMO) communication systems will employ sub-6 GHz and
millimeter wave (mmWave) frequency bands working cooper-
atively. Establishing a MIMO communication link usually relies
on estimating channel state information (CSI) which is difficult
to acquire at mmWave frequencies due to a low signal-to-noise
ratio (SNR). In this paper, we propose three novel methods to es-
timate mmWave MIMO channels using out-of-band information
obtained from the sub-6 GHz band. We compare the proposed
channel estimation methods with a conventional one utilizing
only in-band information. Simulation results show that the
proposed methods outperform the conventional mmWave channel
estimation method in terms of achievable spectral efficiency,
especially at low SNR and high K-factor.
