1. A method of wireless communication for a base station, the method comprising:
sending a beam modification command that indicates a set of transmit beam indexes corresponding to a set of transmit beams associated with the base station and indicates a first set of symbol indexes corresponding to a first set of symbols of a reference signal, each transmit beam index of the set of transmit beam indexes indicating at least a transmit direction for transmitting a transmit beam by the base station, wherein the beam modification command is included in one of a medium access control element (MAC) control element (CE) or a downlink control information (DCI) message, and wherein the reference signal comprises a channel-state information reference signal (CSI-RS); and
sending, in association with the beam modification command, the reference signal using at least one transmit beam of the set of transmit beams, wherein a first portion of the reference signal is sent in the first set of symbols.
