Claim 0:
1. A terminal comprising:
a receiver that receives information indicating a first number of preamble transmissions, the information being a condition for switching from a 2-step random access procedure to a 4-step random access procedure, and information indicating a second number which is a maximum number of preamble transmissions; and
a processor that when a number of preamble transmissions is the first number, controls to switch from a 2-step random access procedure to a 4-step random access procedure, and when the number of preamble transmissions is the second number, determines a failure of the 4-step random access procedure that has been switched from the 2-step random access procedure,
wherein the processor controls, based on the information indicating the second number, whether or not to report, to a higher layer, the failure of the 4-step random access procedure that has been switched from the 2-step random access procedure.
