Abstract
Apparatuses and method for calibration for multiple transmission and reception point (multi-TRP) coherent joint transmissions. A method performed by a user equipment (UE) includes receiving configuration information about N downlink (DL) antenna port groups, N uplink (UL) antenna port groups, wherein the N DL antenna port groups are associated with the N UL antenna port groups, respectively and receiving an indicator to trigger M DL antenna port groups, where M≤N. The method further includes measuring a DL reference signal (RS) for the triggered M DL antenna port groups; determining, based on the measured DL RS, an UL precoder for each of M UL antenna port groups respectively associated with the triggered M DL antenna port groups; and transmitting, based on the UL precoder, an UL RS for the M associated UL antenna port groups.
