1. A user equipment (UE) configured to perform a random access procedure in a wireless communication system, the UE comprising:a transceiver configured to transmit or retransmit a random access preamble for the random access procedure to a network, and to receive a random access response; and
a processor comprising a MAC (Medium Access Control) layer entity and a physical layer entity,
wherein the MAC layer entity is configured to set a parameter for a transmission power of the transceiver for transmitting or retransmitting the random access preamble based on (a counter value?1)*power ramping value,
wherein the MAC layer entity comprises a first MAC layer entity and a second MAC layer entity, and
wherein the physical layer entity is configured to send a notification of suspending to the second MAC layer entity, based on the physical layer cannot transmit the random access preamble instructed from the second MAC layer entity due to a transmission of the random access preamble instructed from the first MAC layer entity, such that the second MAC layer entity does not increase the counter value.
