1. A method comprising:
transmitting, by a base station to a wireless device, one or more radio resource control (RRC) messages indicating two-step random access resources of a two-step random access type; and
receiving, while the two-step random access type and a four-step random access type are available for a random access procedure and based on the two-step random access resources comprising contention-free two-step random access resources, a preamble via the contention-free two-step random access resources.
