To increase network capacity and coverage, new deployment strategies are being explored for beyond-5G networks. Building on the unique features and potentials of lampost-based access points (APs) for hotspot deployment scenarios, this work investigates the performance of three hybrid precoding techniques at the APs, where the analog RF beamformer is based on orthogonal matching pursuit (OMP) and modified generalized low rank approximation of matrices (MGLRAM) while the digital baseband precoder is based on maximum ratio transmission (MRT) and zero forcing (ZF) precoding schemes. The performance of these hybrid precoding techniques is compared to the SVD-based upper bound. Using a stadium deployment as sample use case, this work considers a multi-cell, multi-user THz Massive MIMO operation for harnessing beamforming and multiplexing gains, where the APs use hybrid precoding while users employ analog-only beamforming. The spectral efficiency results show that this deployment strategy can deliver ultra-broadband connectivity for next-generation short-range communication networks.
