Initial Access for Millimeter-Wave and Terahertz Communications with Hybrid Beamforming
Wei Jiang, Hans D. Schotten
In order to achieve terabits-per-second (Tbps) data rates in the sixth-generation (6G) mobile system, wireless communications are required to exploit the abundant spectrum in the m…
Initial Beamforming for Millimeter-Wave and Terahertz Communications in 6G Mobile Systems
Wei Jiang, Hans D. Schotten
To meet the demand of supreme data rates in terabits-per-second, the next-generation mobile system needs to exploit the abundant spectrum in the millimeter-wave and terahertz bands…
Opportunistic AP Selection in Cell-Free Massive MIMO-OFDM Systems
Wei Jiang, Hans D. Schotten
Exploiting the degree of freedom in the frequency domain and the near-far effect among different access points (APs), this paper proposes an opportunistic transmission scheme in ce…
Dual-Beam Intelligent Reflecting Surface for Millimeter and THz Communications
Wei Jiang, Hans Dieter Schotten
Intelligent reflecting surface (IRS) is a cost-efficient technique to improve power efficiency and spectral efficiency. However, IRS-aided multi-antenna transmission needs to joint…
