1. A method for transmitting data, the method comprising:
sending a first probing packet using a first scanning beam, selected from a set of scanning beams;
determining feedback about the first probing packet;
sending a second probing packet using a second scanning beam, selected from the set of scanning beams based on the determined feedback about the first probing packet;
determining feedback about the second probing packet, wherein the feedback about the first probing packet and the feedback about the second probing packet is received after a delay, characterized by a delay parameter;
determining a data transmission beam based on the set of scanning beams and the determined feedback about the first probing packet and the second probing packet; and
transmitting data using an antenna that is configured according to the determined transmission beam.
