1. A method for wireless communication at a user equipment (UE), comprising:
transmitting a first message indicating at least a random access preamble for a random access procedure based at least in part on a configuration;
transmitting, as part of the random access procedure and after transmitting the first message indicating the at least random access preamble, a plurality of reference signals using a plurality of directional beams;
receiving, from a network device and based at least in part on transmitting the plurality of reference signals, a second message indicating a directional beam of the plurality of directional beams and a set of resources for transmitting a third message; and
transmitting, as part of the random access procedure, the third message over the set of resources using the indicated directional beam.
