Techniques for using a data channel for beam refinement

Abstract:

Methods, systems, and devices for wireless communications are described. For example, a first wireless device may transmit, via a first beam, a first set of data and a first reference signal associated with the data on a data channel for beam refinement. The first wireless device may further transmit, via a second beam, a second set of data and a second reference signal on the data channel for beam refinement. A second device may receive the first set of data and first reference signal in addition to receiving the second set of data and second reference signal. The second device may transmit, to the first device, beam refinement feedback information for the first beam and the second beam based on receiving the first reference signal and the second reference signal on the data channel. Thus, the first device may refine beams based on a data transmission over a data channel.
