Abstract: Provided are a method and an apparatus for transmitting uplink data in a wireless communication system. Specifically, a first terminal transmits a random access preamble for requesting a connectionless transmission. The first terminal receives a random access response comprising scheduling information of the uplink data. The first terminal transmits uplink data and a reference signal from a first resource configured on the basis of scheduling information of the uplink data and information indicating the CP length of the reference signal. The CP length of the reference signal can be configured to be identical to the CP length of the random access preamble. The first resource can correspond to a resource utilized by both the first terminal and second terminal.

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.
