Abstract
Methods, systems, and devices for wireless communications are described. A first device may transmit, to a second device, reference signals using combinations of analog beamforming parameters over multiple cycles. The reference signals may be transmitted for different combinations of transmit beamforming parameters and receive beamforming parameters over different cycles of the multiple cycles. The first device may receive, from the second device over the multiple cycles, a set of reports. Each report may indicate combinations of analog beamforming parameters selected for the analog beamforming parameters at the second device. Each combination of analog beamforming parameters may correspond to different cycles of the multiple cycles. The first device may set, for each radio frequency (RF) chain of a plurality of RF chains associated with the first device, a corresponding combination of analog beamforming parameters, and communicate with the second device via two or more beams based on the setting.
