Device and method for transmitting random access preamble

A terminal for receiving a random access channel (RACH) resource in a wireless communication system employing time division duplex (TDD) mode, the terminal comprising:

• a generator configured to generate a random access preamble;
• and
• a transceiver configured to:
• receive, from a base station, RACH resource allocation information allocating the RACH resource in an uplink pilot time slot (UpPTS), and
• transmit, to the base station, the random access preamble in the UpPTS,
• wherein first resource blocks of the RACH resource are configured in a first time and second resource blocks of the RACH resource are configured in a second time,
• wherein the first resource blocks and the second resource blocks are configured to different frequency bands, and
• wherein the first resource blocks and the second resource blocks are determined based on a RACH resource frequency index.

A method for allocating a random access channel (RACH) resource by a base station in a wireless communication system employing time division duplex (TDD) mode, the method comprising:

• generating RACH resource allocation information to allocate the RACH resource in an uplink pilot time slot (UpPTS);
• transmitting, to a terminal, the RACH resource allocation information;
• and
• receiving, from the terminal, a random access preamble in the UpPTS,
• wherein first resource blocks of the RACH resource are configured in a first time and second resource blocks of the RACH resource are configured in a second time,
• wherein the first resource blocks and the second resource blocks are configured to different frequency bands, and
• wherein the first resource blocks and the second resource blocks are determined based on a RACH resource frequency index.
