    Abstract: The present invention relates to a wireless communication system and, specifically, to a method comprising the steps of: transmitting first A/N information; receiving one or more data after transmitting the first A/N information; receiving downlink control information including a 1-bit indicator; and transmitting second A/N information including an A/N result for the one or more data depending on whether the 1-bit indicator is toggled, and to an apparatus therefor, wherein the second A/N information is generated by reflecting only a data reception state after the transmission of the first A/N information, on the basis of a case where the 1-bit indicator has been toggled; and the second A/N information is generated in consideration of (i) the first A/N information and (ii) the data reception state after the transmission of the first A/N information, on the basis of a case where the 1-bit indicator has not been toggled.

    Abstract: The present specification provides a method for transmitting and receiving downlink control information (DCI) in a wireless communication system supporting narrow band-Internet of things (NB-IoT). Specifically, a terminal monitors at least one first candidate PDCCH in a first search space and at least one second candidate PDCCH in a second search space, wherein the first search space and the second search space may partially or entirely overlap each other on a time axis. Thereafter, the terminal may search for a first DCI in the at least one first candidate PDCCH and a second DCI in the at least one second candidate PDCCH, wherein the sum of the number of the at least one first candidate PDCCH and the number of the at least one second candidate PDCCH may be less than or equal to a specific number.

    Abstract: The present invention relates to a wireless communication system, and more particularly, to a method of transmitting and receiving a radio signal and an apparatus therefor. The method comprises the steps of receiving data in a time unit #n of a first frequency band and transmitting A/N in a time unit #m+k of a second frequency band in response to the data. In this case, the first frequency band and the second frequency band have different subcarrier spacing and a time unit #m of the second frequency band indicates the last time unit among a plurality of time units of the second frequency band corresponding to the time unit #n of the first frequency band.

    Abstract: The present invention relates to a wireless communication system. Specifically, the present invention relates to a method for transmitting, by a terminal, a HARQ-ACK in a CA wireless communication system and an apparatus therefor, the method comprising: receiving at SF #n−k one or more DG DCIS containing a first DAI; receiving a UG DCI which schedules a PUSCH; and transmitting at SF #n a HARQ-ACK payload over the PUSCH, wherein the size of the HARQ-ACK payload is determined on the basis of a value of the first DAI, the value of the first DAI corresponds to the total number of cells on which a first type of DL signal is scheduled at the SF #n−k with respect to the terminal, n is an integer of 0 or more and k is a positive integer.
