Low-Overhead Channel Estimation via 3D Extrapolation for TDD mmWave Massive MIMO Systems Under High-Mobility Scenarios

B Zhou, X Yang, S Ma, F Gao, G Yang - arXiv preprint arXiv:2406.08887, 2024 - arxiv.org
In TDD mmWave massive MIMO systems, the downlink CSI can be attained through uplink
channel estimation thanks to the uplink-downlink channel reciprocity. However, the channel …
