Abstract: According to one embodiment of the present invention, a method of receiving a downlink signal by a machine type communication user equipment (MTC UE) in a wireless communication system can comprise obtaining frequency hopping information on a plurality of subbands included in a downlink band and repeatedly receiving the downlink signal via different subbands based on the frequency hopping information. In this case, the downlink band includes ⌊ N RB 6 ⌋ number of subbands each configured as 6 resource block (RB) size and ‘NRB’ corresponds to a size of the downlink band. If a remaining band which does not belong to the ⌊ N RB 6 ⌋ number of subbands and is smaller than 6 RB size exists in the downlink band, at least one of a lowest index RB, a highest index RB and an intervening RB between subband groups in the downlink band may be configured as the remaining band.

Abstract: The present invention determines a PUCCH resource based on which serving cell ACK/NACK information is related to, when a user device set as a plurality of serving cells transmits the ACK/NACK information. Moreover, if a PUCCH transmission time matches with a PUSCH transmission time, the present invention does not piggy back ACK/NACK information to PUSCH but transmits the ACK/NACK information through PUCCH.

Abstract: Disclosed is a method by which a terminal transmits channel status information (CSI) feedback in a wireless communication system. Particularly, the method for transmitting CSI feedback comprises the steps of: setting, through an upper layer signal, one CSI process having a periodic reference signal and an aperiodic reference signal; receiving, from a base station, an aperiodic CSI feedback request message related to the one CSI process; generating, in response to the aperiodic CSI feedback request message, aperiodic CSI feedback on the basis of the aperiodic reference signal; and transmitting the aperiodic CSI feedback to the base station.
