1. A computer-implemented method for finding a data transmission beam from an Access Point (AP) to a User Equipment (UE) in a communication system, the method comprising:
sending a plurality of probing packets from the AP to the UE using a probing beam selected for each probing packet from among a set of probing beams;
receiving feedback from the UE regarding the plurality of probing packets; and
computing the data transmission beam based on the received feedback and the set of probing beams, each of the probing beams from the set of probing beams comprising an angular coverage interval corresponding to a respective single contiguous main lobe from a set of single contiguous main lobes.
