1. A terminal, comprising:
a processor,
wherein the processor causes the terminal to:
receive first random access (RA) configuration information and second RA configuration information from a base station;
transmit a Msg1 to the base station based on the second RA configuration information;
receive a Msg2, which is a response to the Msg1, from the base station; and
repeatedly transmit a Msg3 K times to the base station,
wherein the Msg3 is not repeatedly transmitted in a first RA procedure according to the first RA configuration information, the second RA configuration information is used when a first condition is satisfied, the Msg3 is repeatedly transmitted in a second RA procedure according to the second RA configuration information, and K is a natural number.
