HIERARCHICAL CHANNEL STATE INFORMATION (CSI) FEEDBACK WITH PARTIAL RECIPROCITY IN A NETWORK
Document Type and Number:
WIPO Patent Application WO/2022/027631
Kind Code:
A1
Abstract:
A base station or other network component (next generation NodeB (gNB) ) can operate to transmit a channel state information reference signal (CSI-RS) for channel state information (CSI) feedback. The CSI feedback can be received as corresponding to one or more frequency parts at hierarchical precoding levels of a frequency band based on a hierarchical precoding scheme in response to providing the CSI-RS.
