Abstract

See full text

A user equipment (UE), or other network component can operate to configure channel state information (CSI) feedback in response to receiving a CSI-reference signal (CSI-RS) according to a hierarchical precoding scheme that selectively reduces a feedback overhead associated with the CSI feedback. The UE can operate to divide and further sub-divide a frequency band (e.g., a wideband, or particular frequency part) into a precoding hierarchy to generate precoders for conveyance to a base station, eNodeB (eNB), or next generation NodeB (gNB) via the CSI feedback.
