Methods and apparatus for transmitting rach in wireless communication system

A terminal in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• at least one processor coupled to the transceiver, the at least one processor configured to:
• receive configuration information regarding a random access channel (RACH) from a base station;
• and
• transmit a RACH preamble based on the configuration information,
• wherein the configuration information includes first information indicating the number of RACH transmission occasions in a frequency axis, and second information indicating a start symbol of the RACH.

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• at least one processor coupled to the transceiver and configured to:
• transmit configuration information regarding a random access channel (RACH) to a user equipment (UE);
• and
• receive a RACH preamble based on the configuration information,
• wherein the configuration information includes first information indicating the number of RACH transmission occasions in a frequency axis and second information indicating a start symbol of the RACH.
