Title:
CODEBOOK SUBSET RESTRICTION FOR FREQUENCY DOMAIN COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2020/113547
Kind Code:
A1
Abstract:
Certain aspects of the present disclosure generally relate to methods and apparatus for channel estimation with frequency compression. One example method for wireless communication generally includes receiving at least one pilot signal from a base station, identifying spatial domain compression beams based on the at least one pilot signal, identifying a codebook subset restriction indicating one or more amplitude restrictions for each of a plurality of frequency domain basis, generating a channel state information (CSI) report with frequency compression and with the spatial domain compression beams in accordance with the codebook subset restriction, and transmitting the CSI report.
