Claim 28:
29. A method of wireless communication performed by a user equipment (UE), comprising:
performing an initial random access channel (RACH) attempt by transmitting, to a network entity, an initial request message of an initial two-step RACH procedure,
wherein transmitting the initial request message comprises transmitting an initial request message preamble according to an initial transmission procedure; and
performing an additional RACH attempt, using an alternative two-step RACH procedure, based at least in part on determining that an initial response message, corresponding to the initial request message, of the two-step RACH procedure is not received during an initial random access response (RAR) window,
wherein performing the additional RACH using the alternative two-step RACH procedure comprises transmitting at least one additional request message preamble according to an additional transmission procedure that is different than the initial transmission procedure,
wherein the at least one additional request message preamble comprises a plurality of preamble sequences, and
wherein each preamble sequence of the plurality of preamble sequences is linked to each other preamble sequence of the plurality of preamble sequences.
