Title:

CODEBOOK SUBSET RESTRICTION (CBSR) ON PER SPATIAL DOMAIN AMPLITUDE

Document Type and Number:

WIPO Patent Application WO/2020/252767

Kind Code:

A1

Abstract:

Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with frequency domain (FD) compression. More particularly, aspects of the present disclosure provide for codebook subset restriction (CBSR) on per spatial domain (SD) basis amplitude.
