1. A method of operating a wireless communication device, the method comprising:
before a two-step random access procedure, receiving, from an access node of a communication network, a message comprising a configuration defining at least one of multiple different types of scheduling that differ in how an occasion for transmitting the uplink message is defined, and that are usable for resource allocation of an uplink shared channel of the communication network during the two-step random access procedure, the configuration informing the wireless communication device how to identify the occasion for uplink transmission on the uplink shared channel during the two-step random access procedure, and
enabling transmission of an uplink message of the two-step random access procedure on the uplink shared channel in accordance with the configuration, the uplink message including a connection request for establishing a data connection between the wireless communication device and the communication network.
