1. An apparatus for wireless communications at a user equipment (UE), comprising:
a processor; and
memory coupled to the processor, the processor configured to:
receive, from a network device, a system information message that comprises a timing offset value;
transmit, to the network device via a physical random access channel, a random access preamble message in accordance with a transmission timing for the random access preamble message, the transmission timing for the random access preamble message based at least in part on the timing offset value;
receive, from the network device and in response to the random access preamble message, a random access response message that comprises a timing advance value, the timing advance value based at least in part on the transmission timing for the random access preamble message; and
transmit, to the network device via a second channel different from the physical random access channel, a subsequent message based at least in part on the timing advance value and the timing offset value set to zero.
