Massive MIMO Transmission for LEO Satellite Communications
TL;DR: In this paper, the authors proposed a massive MIMO transmission scheme with full frequency reuse (FFR) for LEO satellite communication systems and exploited statistical channel state information (sCSI) to address the difficulty of obtaining instantaneous CSI at the transmitter.

Ke-Xin Li,Li You,Jiaheng Wang,Xiqi Gao,Christos G. Tsinos,Symeon Chatzinotas,Bjorn Ottersten +6 more
TL;DR: This paper investigates the downlink (DL) transmit design for massive multiple-input multiple-output (MIMO) low-earth-orbit (LEO) satellite communication systems, where only the slow-varying statistical channel state information is exploited at the transmitter.
Proceedings ArticleDOI
LEO Satellite Communications with Massive MIMO
TL;DR: A massive MIMO downlink transmission scheme with full frequency reuse (FFR) for LEO satellite communication systems by exploiting statistical channel state information (sCSI) at the transmitter and a closed-form low-complexity sCSI based DL precoder is developed.
Journal ArticleDOI
Non-Orthogonal Unicast and Multicast Transmission for Massive MIMO With Statistical Channel State Information
TL;DR: Simulation results show that the proposed NOUM transmission can provide a significant performance gain in terms of the achievable ergodic unicast-multicast rate region over the conventional orthogonal approach.
