1. A method performed by a wireless communication node, the method comprising:
receiving, from a wireless communication device, a first message comprising a preamble and a payload for an access to the wireless communication node; and
transmitting, to the wireless communication device, a second message in response to the first message,
wherein:
the second message is transmitted based on a random access radio network temporary identifier (RA-RNTI), a fixed offset being added in a calculation of the RA-RNTI for transmitting the second message in a 2-step random access channel (RACH) procedure compared to a 4-step RACH procedure, the fixed offset being a multiple of 14×80×8.
