Multiple message types and procedure for selection of a message type for a random access message in a two-step random access procedure

A method of wireless communication performed by a base station, comprising:

• receiving, from a user equipment (UE), a random access message associated with a two-step random access channel (RACH) procedure;
• determining, based at least in part on the random access message, a message type of the random access message,
• wherein the message type is either a first message type or a second message type, the first message type being different from the second message type;
• and
• processing the random access message based at least in part on determining the message type of the random access message.

A user equipment (UE) for wireless communication, comprising:

• a memory;
• and
• one or more processors operatively coupled to the memory, the memory and the one or more processors configured to:
• determine a message type for a random access message associated with a two-step random access channel (RACH) procedure,
• wherein the message type is either a first message type or a second message type, the first message type being different from the second message type, and
• wherein the message type is determined based at least in part on whether a signal strength satisfies a signal strength threshold;
• and
• transmit the random access message based at least in part on the determined message type.
