Claim of US Patent No. 10,716,148

1. A method for transmitting, by a user equipment (UE), a random access preamble in a wireless communication system, the method comprising:performing a first random access preamble transmission for a first synchronization signal (SS) block at a first transmission power; and
performing a second random access preamble transmission for a second SS block at a second transmission power based on not successfully receiving a random access response to the first random access preamble transmission,
wherein the second transmission power is determined based on a power ramping counter value used for determination of the first transmission power based on the second SS block being different from the first SS block.
