    摘要： The present disclosure relates to a method performed by a terminal in a wireless communication system, the method comprising determining whether to report a first type power headroom report, PHR, or a second type PHR, based on a scheduling signaling for a physical uplink shared channel, PUSCH, transmission; in case that the scheduling singling for the PUSCH transmission is received, transmitting, to a base station, transmitting, to a base station, the first type PHR; and in case that the scheduling singling for the PUSCH transmission is not received, transmitting, to the base station, the second type PHR, wherein the first type PHR comprises a power headroom, PH, calculated based on the scheduling signaling for the PUSCH transmission, and wherein the second type PHR comprises a PH calculated based on a default configuration.

    摘要： A method is performed by a terminal in a wireless communication system. The terminal transmits, to a base station, a random access preamble and increases a preamble transmission counter for a retransmission of the random access preamble, in case that a random access response for the random access preamble is not received within a random access window. It identifies a transmission power for the retransmission of the random access preamble based on a preamble power ramping counter, wherein the preamble power ramping counter is increased in case that a transmission beam for the retransmission is not changed, and the preamble power ramping counter is maintained in case that the transmission beam for the retransmission is changed. The method comprises transmitting, to the base station, the random access preamble by using the transmission power.
