Abstract: The present invention relates to a wireless communication system and provides a method and a device for same. The method comprises the steps of: receiving information about SPS transmission periods; confirming information about the number of SPS repetitions; and receiving SPS data, which is newly and repeatedly transmitted in every SPS transmission period, on the basis of the SPS transmission periods and the number of the SPS repetitions, wherein, if the SPS transmission periods are greater than the number of the SPS repetitions, a frequency band in which the SPS data is received is maintained to be the same in every SPS transmission period and, if the SPS transmission periods are smaller than the number of the SPS repetitions, the frequency band in which the SPS data is received is switched in every SPS transmission period.

Abstract: Provided are a method whereby a terminal transmits an acknowledgement/not-acknowledgement (ACK/NACK) with a primary cell and a secondary cell aggregated, and a device for supporting the method. The method comprises: receiving data by a downlink subframe of a secondary cell; and transmitting an ACK/NACK for the data by an uplink subframe of a primary cell, wherein: the time interval between the downlink subframe and the uplink subframe is determined by a first hybrid automatic repeat request (HARQ) timing or a second HARQ timing; the first HARQ timing is an HARQ timing which is applied when the primary cell is used alone; and the second HARQ timing is an HARQ timing which is additional to the first HARQ timing.

Abstract: The present invention relates to signal transmission and reception method and device by an equipment which is dual-connected to a first radio access technology (RAT) and a second RAT in a wireless communication system. The method comprises the steps of: a first signal in accordance with a first RAT and a second signal in accordance with a second RAT being scheduled separately timewise; and transmitting and receiving the first signal and the second signal. The operation for the second signal is determined on the basis of whether or not the second signal reception is scheduled in a first time domain for transmitting the first signal. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: A method and apparatus for allocating resources for a machine type communication user equipment (MTC UE) in a wireless communication system is provided. A base station indicates a transport block size (TBS) directly, adapts a code rate according to repetition numbers across multiple subframes in a MTC physical downlink shared channel (M-PDSCH) for the MTC UE, and allocates resources for the M-PDSCH by using the indicated transport block size and the adapted code rate. The TBS may be determined based on a modulation and coding scheme (MCS) only.

Abstract: A method for receiving Physical Downlink Shared Channel (PDSCH) in a user equipment (UE) from a base station (BS) in a wireless communication system. In the method, the UE receives information for at least one control resource set (CORESET) and information for a CORESET not used for the PDSCH among the CORESET. Furthermore, the UE receives the PDSCH in resources other than the CORESET not used for the PDSCH. In other words, the PDSCH is not mapped into the CORESET not used for the PDSCH. In addition, a demodulation reference signal (DMRS) for the PDSCH is received in an orthogonal frequency division multiplexing (OFDM) symbol after the at least one CORESET when a region for PDSCH overlaps a region for the at least one CORESET.

Abstract: A method and apparatus for transmitting a power headroom report (PHR) in a wireless communication system is provided. A user equipment (UE) transmits a first PHR for a first carrier group, which is configured by a first eNodeB (eNB), to a second eNB; and transmitting a second PHR for a second carrier group, which is configured by the second eNB, to the first eNB. The first PHR and the second PHR include a PHR for a physical uplink control channel (PUCCH) regardless of whether simultaneous transmission of the PUCCH and a physical uplink shared channel (PUSCH) is configured or not.
