Method and apparatus for transmitting and receiving data in wireless communication system

A method of allocating, by a base station, a resource for random access procedure to a terminal, the method comprising:

• transmitting a system information block 1 (SIB1) comprising first information indicating a Msg3 transmission repetition and second information indicating a number of repetitions of a Msg3 transmission;
• receiving a random access preamble based on a physical random access channel (PRACH) resource based on the first information;
• transmitting a random access response (RAR) in response to the reception of the random access preamble;
• and
• receiving the repetitions of the Msg3 transmission, based on the second information.

A terminal performing random access procedure, the terminal comprising:

• a transceiver;
• and
• at least one processor connected to the transceiver,
• wherein the at least one processor is configured to
• receive a system information block 1 (SIB1) comprising first information indicating a Msg3 transmission repetition and second information indicating a number of repetitions of a Msg3 transmission,
• select a physical random access channel (PRACH) resource based on the first information,
• transmit a random access preamble based on the selected PRACH resource,
• receive a random access response (RAR) in response to the transmission of the random access preamble,
• perform the repetitions of the Msg3 transmission, based on the second information, and
• start a timer for a contention resolution after an end of all the repetitions of the Msg3 transmission.

A base station allocating a resource for random access procedure to a terminal, the base station comprising:

• a transceiver;
• and
• at least one processor connected to the transceiver,
• wherein the at least one processor is configured to:
• transmit a system information block 1 (SIB1) comprising first information indicating a Msg3 transmission repetition and second information indicating a number of repetitions of a Msg3 transmission,
• receive a random access preamble based on a physical random access channel (PRACH) resource based on the first information,
• transmit a random access response (RAR) in response to the reception of the random access preamble, and
• receive the repetitions of the Msg3 transmission, based on the second information.
