1. An operation method of a terminal in a wireless communication system, the method comprising:
identifying a priority between uplink (UL) data and sidelink data;
transmitting at least one of the UL data or the sidelink data based on the identified priority;
in case that the terminal is not capable of simultaneous transmissions of the UL data and the sidelink data, transmitting a first data having a higher priority between the UL data and the sidelink data based on the identified priority; and
in case that the terminal is unable to simultaneously transmit the UL data and the sidelink data with a predetermined transmission power, transmitting a second data using a first transmission power and a third data having a lower priority between the UL data and the sidelink data using a second transmission power, wherein the second transmission power is low power identified based on the lower priority and a total of the first transmission power and the second transmission power does not exceed a maximum transmission power,
wherein the priority of the UL data and the sidelink data is identified based on at least one of a logical channel of the UL data and the sidelink data, and wherein a logical channel for a medium access control (MAC) control element (CE) for buffer status report (BSR) with exception of BSR included for padding has a higher priority than a logical channel for a MAC CE for sidelink BSR with exception of sidelink BSR included for padding,
wherein the logical channel for the MAC CE for the sidelink BSR with exception of the sidelink BSR included for padding has a higher priority than a logical channel for a MAC CE for UL BSR included for padding, and
wherein the logical channel for the MAC CE for the UL BSR included for padding has a higher priority than a logical channel for a MAC CE for the sidelink BSR included for padding.
