Abstract: A method of receiving, by a user equipment (UE) that is configured to operate in transmission mode 10, downlink data in a wireless communication system. The method includes: receiving, in a transmission time interval (TTI), downlink control information (DCI) that includes resource element (RE) mapping information. The method also includes receiving, in a plurality of TTIs subsequent to the TTI in which the DCI was received, repeated transmissions of the downlink data to which the RE mapping information has been applied.

Abstract: A method of receiving, by a user equipment (UE), a reference signal in a wireless communication system. The method includes: receiving downlink control information (DCI) for scheduling downlink data in a first transmission time interval (TTI); acquiring, from the DCI, information related to whether the reference signal is included in the first TTI in which the downlink data is scheduled; and receiving, in the first TTI, the reference signal for the first TTI based on the information related to whether the reference signal is included in the first TTI. The method further includes, based on the downlink data scheduled to be repeatedly transmitted in the first TTI and at least one second TTI: receiving, in each of the at least one second TTI, a reference signal for the each of the at least one second TTI.

Abstract: The present invention discloses a method for transmitting a scheduling request and a device therefor in a wireless communication system. More specifically, the method performed by a user equipment (UE) includes receiving, from a base station, sounding reference signal (SRS) configuration information related to SRS transmission, and transmitting, to the base station, at least one SRS indicating a specific SR of a plurality of SRs based on the SRS configuration information. The SRS configuration information includes at least one of cyclic shift (CS) index information of a sequence related to the SRS transmission, comb information representing a comb structure in which the sequence is transmitted, or hopping bandwidth information related to the SRS transmission. The specific SR is indicated according to at least one of an CS index selected based on the CS index information, a comb index selected based on the comb information, or a hopping pattern based on the hopping bandwidth information.

Abstract: A method for transmitting an uplink control channel in a wireless communication system and a device therefor are disclosed. In detail, the method performed by a user equipment (UE) includes generating a third sequence by aggregating a first sequence with a second sequence, generating a fourth sequence by using the generated third sequence and a specific cyclic shift index corresponding to specific uplink control information, and transmitting the uplink control channel by using the generated fourth sequence, wherein the fourth sequence may be transmitted in at least one symbol constituting a resource region allocated for transmission of the uplink control channel, and wherein the fourth sequence may indicate the specific uplink control information transmitted through the uplink control channel.

Abstract: The present invention provides a method of transmitting a channel quality indicator (CQI) in a wireless communication system. The method performed by a user equipment supporting a relatively shorter transmission time interval (S-TTI) than a legacy transmission time interval (L-TTI) includes determining predefined control channel-related overhead depending on whether S-TTI-based communication is performed and transmitting the CQI based on the determined predefined control channel-related overhead. If the S-TTI-based communication is performed, the predefined control channel-related overhead is identically determined between an S-TTI including a legacy physical downlink control channel (PDCCH) region and a S-TTI not including a legacy PDCCH region.

Abstract: Disclosed are a method and apparatus for transmitting an uplink channel in a wireless communication system. A method for transmitting an uplink channel in a wireless communication system supporting an sTTI is performed by a terminal incapable of the simultaneous transmission of a first uplink channel and a second uplink channel, and includes when a first uplink channel region at a first sTTI overlaps a specific symbol included in a second uplink channel region at a second sTTI, transmitting the first uplink channel to a base station using at least one of a plurality of symbols included in the first uplink channel region symbol other than the specific symbol at the first sTTI and transmitting the second uplink channel to the base station using at least one symbol included in the second uplink channel region at the second sTTI. The specific symbol includes a symbol to which a DMRS related to the second uplink channel is mapped.
