Fast Multibeam Training for RIS-Assisted Millimeter Wave Massive MIMO
Zhang, C; Qi, C; Nallanathan, A (IEEE, 2023-11-16)For reconfigurable intelligent surface (RIS)-assisted mmWave massive MIMO, we propose a fast multibeam training (FMT) scheme with two stages. In the first stage, we find a multibeam together with the RIS reflection ... -
Multiuser Beamforming for Partially-Connected Millimeter Wave Massive MIMO
Qi, C; Hu, J; Du, Y; Nallanathan, A (IEEE, 2023-11-10)Multiuser beamforming is considered for partially-connected millimeter wave massive MIMO systems. Based on perfect channel state information (CSI), a low-complexity hybrid beamforming scheme that decouples the analog ...
