Abstract
Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may perform one or more operations for receive antenna switching. For example, a UE may receive a set of reference signals from a base station using one or more ports of the UE. Based on receiving the set of reference signals, the UE may generate channel state information (CSI) associated with a set of antenna ports. In some cases, the UE may generate CSI based on receiving a configuration indicating the set of antenna ports. The UE may transmit, to the base station, a CSI report including the CSI information associated with the set of antenna ports and an indication of the associated antenna ports. The base station may receive the CSI report and may communicate with the UE using a set of precoders associated with the set of indicated antennas ports.
