1. A method of wireless communication by a user equipment (UE), the method comprising:
transmitting, to a base station, a random access channel preamble over a first bandwidth of a system bandwidth that is less than the system bandwidth;
receiving, from the base station after transmitting the random access channel preamble, a random access channel response over the first bandwidth;
receiving, from the base station after transmitting the random access channel preamble, one or more reference signals over one or more portions of a second bandwidth of the system bandwidth, the second bandwidth being wider than the first bandwidth, the one or more portions of the second bandwidth being different than the first bandwidth, the one or more reference signals being usable for determining a beam to be used for data communication over the second bandwidth; and
receiving, from the base station, a physical downlink shared channel (PDSCH) over the second bandwidth via the beam based on the one or more reference signals.
