1. A method performed by a wireless communication device, the method comprising:
transmitting, to a wireless communication node, a first message comprising a preamble and a payload for an access to the wireless communication node;
receiving, from the wireless communication node, a second message comprising a response to the first message, wherein the second message comprises an indication indicating a type of the response from a plurality of types; and
determining, based on the type of the response, that the response is configured for a contention resolution for the access to the wireless communication node or is configured for a fallback to a 4-step random access, wherein when the response is configured for the contention resolution, the response comprises a contention resolution identity (ID) carried in the payload of the first message, wherein the response includes a subheader and a medium access control (MAC) random access response (RAR) associated with the subheader, the indication indicating either the MAC RAR is a fallback MAC RAR or a contention resolution RAR and being carried in the subheader.
