Abstract: Disclosed is a method by which a terminal transmits an acknowledgement (ACK)/negative ACK (NACK) signal in a wireless communication system. In particular, the method is characterized by receiving data from a base station, generating an ACK signal or a NACK signal corresponding to the data, transmitting the ACK signal to the base station on the basis of a first hopping pattern when the ACK signal is generated according to the data, and transmitting the NACK signal to the base station on the basis of a second hopping pattern different from the first hopping pattern when the NACK signal is generated according to the data. The terminal is capable of communicating with at least one of another terminal, a terminal related to an autonomous driving vehicle, the base station or a network.

Abstract: A method for receiving a signal by a terminal in a wireless communication system according to an embodiment of the present invention can comprise a step for determining REGs, which are to be assumed that the same precoding is used, among REGs comprised in a control resource set on the basis of information relating to precoder granularity, and thus monitoring a control channel candidate. Particularly, if a part of resource blocks overlaps another resource region and particular resource blocks in the resource blocks are no longer contiguous due to the overlapping, the terminal can comprise an assumption that the same precoding is used with respect to the REGs comprised in the particular resource blocks even if the information relating to the precoder granularity corresponds to first configuration.

Abstract: A method and apparatus for handling a soft buffer size in a wireless communication system is provided. It is assumed that a user equipment (UE) is connected to both a long-term evolution (LTE) system and a new radio access technology (NR) system in dual connectivity. The UE determines a first UE capability for the LTE system and a second UE capability for the NR system, determines a total soft buffer size based on the first UE capability and the second UE capability, and shares the total soft buffer size between the LTE system and the NR system based on at least one of a maximum transport block size (TBS) per transmission time interval (TTI) and a number of carriers used in the NR system.

Abstract: The present invention relates to a wireless access system supporting machine type communication (MTC), and to various methods for an MTC terminal transmitting/receiving data. A method for an MTC terminal receiving data in a wireless access system supporting MTC, as one embodiment of the present invention, may comprise the steps of: receiving a modulation and coding scheme (MCS) index indicating a MCS, and a physical resource block (PRB) index indicating the size of a PRB allocated to a MTC terminal; checking a transport block size (TBS) index that is mapped with the MCS index and deriving a TBS on the basis of the TBS index and the PRB index; and on the basis of the TBS, decoding a physical downlink shared channel (PDSCH) in order to receive data. Here, the size of the MCS index is configured to be a 4-bit size, and the TBS index may be configured so as to support only from 0 to 9 for the MTC terminal.
