The disclosure relates to a fifth-generation (5G) or a pre-5G communication system for supporting a higher data transfer rate than a fourth-generation (4G) communication system such as Long-Term Evolution (LTE). The disclosure relates to uplink transmission in a wireless communication system, in which an operating method of a user equipment (UE) may include: receiving information about a UE group to which the same uplink resource is allocated from a base station; receiving uplink resource allocation information corresponding to the UE group from the base station; performing channel access for uplink transmission on the basis of the received uplink resource allocation information; and transmitting uplink data to the base station after accessing a channel, wherein the channel access may be performed using a multilevel threshold value in a contention slot for the UE.

Apparatus and method for uplink transmission in wireless communication system

The present disclosure is related to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4-Generation (4G) communication system such as Long Term Evolution. A method for operating a base station includes transmitting, to a terminal, configuration information for measuring a channel blockage status indicating a degree by which an unlicensed band is occupied by an interference node, receiving information regarding the channel blockage status measured based on the configuration information, transmitting, to the terminal, scheduling information regarding uplink resources generated based on the information regarding the channel blockage status, and receiving data from the terminal based on the scheduling information, wherein the configuration information comprises at least one of information regarding a measurement duration for measuring the channel blockage status, information regarding uplink resources allocated to measure the channel blockage status, and information regarding a channel occupancy time of the base station.
