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

A user equipment (UE) for use in a wireless communication system, the UE comprising:

• a radio frequency (RF) module;
• and
• a processor, wherein the processor is configured to:
• transmit N (N>1) first random access (RA) signals during a first duration;
• monitor a response signal (RAR) to the plurality of first RA signals;
• and
• after the monitoring of the RAR is failed, transmit N second RA signals during a second duration,
• wherein sounding reference signal (SRS) symbols within the same orthogonal frequency division multiple access symbol (OFDMA symbol) are transmitted in the same transmit beam direction, wherein SRS symbols within different OFDMA symbols are transmitted in different transmit beam directions.
