Claim 29:
30. A method of wireless communication performed by a network entity, comprising:
receiving, from a user equipment (UE), an initial request message of an initial two-step random access channel (RACH) procedure, wherein the initial request message corresponds to an initial RACH attempt,
wherein receiving the initial request message comprises receiving an initial request message preamble that is transmitted according to an initial transmission procedure; and
receiving an additional request message of an alternative two-step RACH procedure, wherein the additional request message corresponds to an additional RACH attempt performed by the UE based at least in part on a failure of the UE to receive an initial response message, corresponding to the initial request message, during an initial random access response (RAR) window,
wherein receiving the additional request message comprises receiving at least one additional request message preamble that is transmitted 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.
