Title:
SELECTION AND QUANTIZATION OF TIME DOMAIN COEFFICIENTS THROUGH AN EXTENDED ETYPE-II CODEBOOK
Document Type and Number:
WIPO Patent Application WO/2023/184147
Kind Code:
A1
Abstract:
This disclosure provides systems, methods, and devices for wireless communication that support selection and quantization of time domain coefficients through an extended eType-II codebook. In a first aspect, a method of wireless communication includes measuring, by a user equipment (UE), a bundle of channel state information reference signals (CSI-RS) to determine channel quality information across a spatial domain, a frequency domain, and a time domain. The UE generates a first bitmap identifying a first plurality of non-zero coefficients (NZCs) selected to represent a first CSI for the spatial domain and the frequency domain, and a second bitmap identifying a second plurality of NZCs selected to represent a second CSI for the time domain. The UE would then transmit one or more CSI reports including one or both of the first bitmap and the second bitmap. Other aspects and features are also claimed and described.
