Abstract: Ultra-massive MIMO（Multiple-Input Multiple-Output） is a potential key technology for 6G mobile communications. Most of the existing channel models assume that all the scatterers are in the far-field region, and adopt the far-field channel model based on the plane wave assumption; Or they are all in the near-field region, using the near-field channel model based on the spherical wave hypothesis. In practice, ultra-massive MIMO systems are more likely to produce hybridfield channel environments. E... More
