Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 4:
5. A terminal in a wireless communication system comprising:
a transceiver; and
at least one processor operatively coupled with the transceiver,
wherein the at least one processor is configured to:
control the terminal to determine whether to report a first type power headroom report (PHR) or a second type PHR, based on a scheduling information for a physical uplink shared channel (PUSCH) transmission,
control the transceiver to transmit, to a base station, the first type PHR, in case that the scheduling information for the PUSCH transmission is received by the terminal,
control the transceiver to transmit, to the base station, the second type PHR, in case that the scheduling information for the PUSCH transmission is not received by the terminal, and
in case that the terminal is configured with at least two serving cells including a first serving cell and a second serving cell that have different slot lengths, control the transceiver to transmit, on a timeslot of the first serving cell, a PHR for a timeslot of the second serving cell,

wherein the first type PHR comprises a power headroom (PH) obtained based on the scheduling information for the PUSCH transmission,
wherein the second type PHR comprises a PH obtained based on a default configuration, and
wherein the timeslot of the second serving cell is a first of a plurality of time slots of the second serving cell that fully overlaps with one timeslot of the first serving cell.
