Abstract

A base station (BS) can include a site-specific and dynamic codebook design. The BS includes an antenna and a transceiver coupled to the antenna and configured to communicate via a wireless communication medium. The BS also includes a processor coupled to the transceiver. The processor is configured to: receive, from a user equipment (UE), a measurement report comprising a best beam index and a corresponding received power; estimate a UE channel including a path gain and angle of departure; update the site-specific codebook based on the estimated UE channel; and transmit control and data signals to the UE using the updated site-specific codebook.
