Sony patents method to fine-tune signal timing in 5G antenna arrays
Sony describes a technique for calibrating the phase of radio signals sent by a network access point. The system sends specific test signals to a device and uses the feedback to adjust the timing of the antenna array.
In the filing’s own words
Various examples relate to phase calibration measurements for calibrating an access node.
What exactly they claim (claim 1)
1. 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.
