Abstract: Provided are a method and an apparatus for measuring inter-RU interference in order to perform space division duplex communication in a wireless communication system. Specifically, a terminal acquires first interference information indicating the strength of inter-RU interference after analog interference cancellation, and second interference information indicating the strength of inter-RU interference before analog interference cancellation. The terminal determines whether space division duplex communication can be performed between RUs, by comparing the interference strength indicated by the first interference information with a first threshold. The terminal determines whether inter-RU interference needs to be periodically measured, by comparing the interference strength indicated by the second interference information with a second threshold.

Abstract: A method and a device for transmitting an uplink transmission block in a wireless communication system are provided. Particularly, a terminal receives, from a base station, allocation information on a first grant-free uplink resource, which is scheduled semi-persistently. The terminal repeatedly transmits a first transmission block through the first grant-free uplink resource by using a first reference signal. The terminal transmits a second transmission block by using a second reference signal before completion of the transmission of the first transmission block. The second transmission block is distinguished from the first transmission block through a change of the first reference signal to the second reference signal.
