Two-step random access procedure in wireless systems

A method for wireless communication, comprising:

• transmitting, by a wireless device, a random access message that comprises at least one of a radio network temporary identifier (RNTI), an identity of the wireless device, an establishment cause, uplink control information (UCI) or beam information;
• and
• receiving, from a network node and in response to transmitting the random access message, a contention resolution message,
• wherein communicating the contention resolution message completes a two-step random access procedure between the wireless device and the network node, and
• wherein at least a portion of the random access message is modulated using a first modulation scheme selected from a modulation group that comprises binary phase shift keying (BPSK) and π/2-BPSK.
