Abstract: Provided are a method and a device for reducing a transmission resource of a control channel in a short TTI in a wireless communication system. Specifically, a plurality of first downlink channels which are received during an sTTI and are included in a subframe corresponding to one TTI, and a second downlink channel received during a TTI are received. Further, information on a resource block used for the plurality of first downlink channels is obtained by using a resource block indicator transmitted to a downlink control channel of a control region comprising the first symbol of a subframe. The plurality of first downlink channels are demodulated by using the information, and the second downlink channel is demodulated by using the downlink control channel.

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 device for transmitting control information in a wireless communication system. In particular, a downlink resource block group including a downlink resource block in a downlink frequency bandwidth is set, and an uplink resource block group including an uplink resource block in an uplink frequency bandwidth is set. If the downlink frequency bandwidth is smaller than the uplink frequency bandwidth, the downlink resource block group is mapped to the uplink resource block group. The ratio of the number of uplink resource blocks to the number of downlink resource blocks is set so that the number of uplink resource block groups and the number of downlink resource block groups become the same. The uplink and downlink resource block groups are mapped according to the ratio. Control information on the mapping is transmitted through the downlink resource block groups.
