Abstract
Apparatuses and methods for CSI codebook for multi-TRP. a method for operating a user equipment (UE) is provided. The method includes receiving a configuration about a channel state information (CSI) report. The configuration includes information about (i) N>1 groups of CSI reference signal (CSI-RS) ports and (ii) a codebook. The codebook includes a spatial-domain (SD) basis component. The SD basis component includes Lbasis vectors for each group r=1, . . . , N. The method further includes, based on the configuration, measuring the N groups of CSI-RS ports and identifying, based on the measurement, the SD basis component. The method further includes transmitting the CSI report. The Lvalues for r=1, . . . , N are indicated by a joint indicator. The joint indicator is a function of the Lvalues.
