Abstract
An example method of calibrating signals in an antenna array includes generating a calibration signal at a first radio sub unit (RSU), transmitting the calibration signal through a transmission path of a radio front end (RFE) of the first RSU, and receiving the calibration signal in a coupling and distribution layer of the first RSU. The method further includes providing the calibration signal from the coupling and distribution layer of the first RSU directly to a coupling and distribution layer of a second RSU, and processing the calibration signal at the second RSU.
