1. A method, comprising:
steering, by a communication device, an antenna unit into a first direction to cause the antenna unit to generate a first constant tone (CT) signal based on a plurality of multipath signals;
performing, by the communication device, a phase measurement on the first CT signal to generate a first phase measurement value;
steering, by the communication device, the antenna unit into a second direction to cause the antenna unit to generate a second CT signal based on the plurality of multipath signals;
performing, by the communication device, a phase measurement on the second CT signal to generate a second phase measurement value;
determining, by the communication device based on the first phase measurement value and the second phase measurement value, a change in multipath interference at the antenna unit among the plurality of multipath signals; and
re-steering, by the communication device responsive to determining the change in multipath interference, the antenna unit into the first direction.
