a receiver that receives an index that specifies first configuration information for transmitting a random access preamble; and
a controller that uses, in response to the receiver receiving the index, the first configuration information for transmitting the random access preamble,
wherein, when a value of a subframe number included in the first configuration information specified by the index in a case where a value of the index is greater than or equal to a specific value is replaced with a value of a subframe number included in second configuration information specified by a specific index with a value that is less than the specific value, the first configuration information is identical to the second configuration information, and
wherein the index with the value that is greater than or equal to the specific value is specified by prach-ConfigurationIndex-v16xy included in RACH-ConfigGeneric information element, and the specific value is 256.
