6. A non-transitory computer-readable storage medium that stores a program for causing a computer provided in a base station apparatus to:
establish a connection with a terminal apparatus via a two-step random access procedure by receiving a first signal including a random access preamble and predetermined information from the terminal apparatus and transmitting a second signal as a reply to the first signal to the terminal apparatus or via a four-step random access procedure; and
when establishing the connection via the two-step random access procedure,
acquire a random access-radio network temporary identifier (RA-RNTI) by adding a predetermined offset value to a value acquired on the basis of a radio resource having been used to transmit the random access preamble with the first signal, and
execute transmission processing of the second signal using the RA- RNTI, and
when establishing the connection via the four-step random access procedure,
acquire a second RA-RNTI on the basis of a radio resource having been used to transmit a random access preamble from the terminal apparatus to the base station apparatus via the four-step random access procedure, and
execute transmission processing of a random access response, which is a reply to the random access preamble, using the second RA-RNTI.
