A method for reporting channel state information in a large-scale antenna system

摘要

The embodiments described herein provide a system and method for constructing a reference signal for multiple panels having a panel-specific Channel State Information Reference Signal (CSI-RS) configuration and a pseudo-placement (QCL) Includes an indication for QCL type definition and panel specific CSI-RS configuration. The exemplary embodiments also provide a multi-component precoder architecture with panel-specific component precoders and panel common pre-coders. Embodiments include (semi) open loop methods using random pre-coding for panel common pre-coder and / or panel specific precoder; Panel Select / limit panel with common precoder; MU-MIMO operation using a different set of panels; Panel-based CSI reporting.
