1. A method of data transmission, comprising the steps of:
receiving, by a base station (BS), from a user equipment (UE), a first set of training signals;
using the first set of training signals to determine a first downlink (DL) beam for DL data transmission;
transmitting data on the first DL beam to the UE;
receiving, by the UE, a second set of training signals;
using the first uplink beam and the second set of training signals to determine a second DL beam for the uplink data transmission; and
transmitting data on the second DL beam to the UE.
