Abstract
A method of operating a network entity includes receiving, via a first TRP and a second TRP, information associated with a SRS from a UE, and estimating a channel based on the information associated with the SRS. The method further includes, for N iterations: transmitting, via a first CSI-RS port from a CSI-RS resource, from the first TRP, a CSI-RS; transmitting, via a second CSI-RS port from the CSI-RS resource, from the second TRP, the CSI-RS with a controlled phase offset; receiving a PMI report associated with the CSI-RS including a measured phase offset between the first CSI-RS port and the second CSI-RS port; and updating the controlled phase offset, based on the measured phase offset. The method further includes, after the N iterations, based on the controlled phase offset and the measured phase offset, determining a phase mis-match for phase calibration between the first TRP and the second TRP.
