Abstract
Various examples relate to phase calibration measurements for calibrating an access node.
Claims21
A method performed by an access node of a communication network, the method comprising:
- providing, to a wireless communication device of the communication network, a message indicative of the access node requiring characterization of phases of multiple pilot signals sequentially transmitted by the access node;
- sequentially transmitting, to the wireless communication device, the multiple pilot signals;
- and
- obtaining an indication of one or more receive properties of the multiple pilot signals.
