1. A processor of a base station configured to perform operations, comprising:
transmitting reference signal configurations to a user equipment (UE), each reference signal configuration corresponding to one transmitter beam;
transmitting beam identification information to the UE comprising at least an indication that one or more reference signal configuration is repeated in time using a same transmitter beam;
transmitting reference signals according to the reference signal configurations; and
receiving, from the UE, a message comprising an indication of a selected-transmitter beam based on the reference signals.
