Abstract
A radio terminal (2) attempts to receive a second message of a 2-step random access procedure after transmitting a first message of the 2-step random access procedure. In response to successfully receiving the second message of the 2-step random access procedure and determining that the second message explicitly or implicitly indicates a fallback to a 4-step random access procedure, the radio terminal (2) further attempts to receive a control message that contains an uplink grant indicating uplink resources available for transmission of a third message of a 4-step random access procedure. This contributes to, for example, reducing the load on a radio terminal that supports a fallback from the 2-step random access procedure to the 4-step random access procedure.
