DISTRIBUTED MIMO CALIBRATION
This abstract first appeared for US patent application 20240429974 titled 'DISTRIBUTED MIMO CALIBRATION
Original Abstract Submitted
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.
