Two-step random access procedure for a backhaul node

A method for wireless communication at a parent network entity, comprising:

• transmitting, to a first wireless node, system information that is indicative of both a first random access procedure configuration for a two-step random access procedure and a second random access procedure configuration for a random access procedure which has more than two steps, wherein the first wireless node is a wireless backhaul node to the parent network entity;
• determining that the first random access procedure configuration instead of the second random access procedure configuration is being used by the first wireless node for communicating with the parent network entity;
• and
• performing the two-step random access procedure with the first wireless node in accordance with the first random access procedure configuration.

An apparatus for wireless communication at a first wireless node, comprising:

• a processor,
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• receive, from a parent network entity, system information that is indicative of both a first random access procedure configuration for a two-step random access procedure and a second random access procedure configuration for a random access procedure which has more than two steps, wherein the first wireless node is a wireless backhaul node to the parent network entity;
• determine to use the first random access procedure configuration instead of the second random access procedure configuration;
• and
• perform the two-step random access procedure with the parent network entity in accordance with the first random access procedure configuration.
