Original Abstract Submitted

apparatuses and methods for calibration for coherent joint transmission. a method performed by a user equipment (ue) includes receiving information about a channel state information (csi) report and determining, based on the information, a reference antenna group. the information indicates nantenna groups, n>1, and a report quantity. the report quantity corresponds to a delay offset (do) or a frequency offset (fo). the method further includes determining, based on the information and the reference antenna group, calibration-related information (cli) for each of the nantenna groups excluding the reference antenna group (n−1) and transmitting the csi report including a cli indicator. the cli indicator indicates the reference antenna group and the cli.
