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: Provided are a method and an apparatus for detecting a random access channel (RACH) preamble on the basis of a plurality of zero-correlation zones (ZCZ) in a wireless communication system. A user equipment (UE) transmits a RACH preamble, generated using a combination of a plurality of sequences corresponding to a plurality of zero-correlation zones, to an evolved NodeB (eNB). The evolved NodeB (eNB) detects a plurality of peaks from the RACH preamble and transmits a random access response to the UE.
