    Abstract: The present disclosure discloses a method of transmitting a hybrid automatic repeat request-acknowledgement (HARQ-ACK) signal at a user equipment (UE) in a wireless communication system. Particularly, the method includes receiving at least one first physical downlink shared channel (PDSCH) related to the HARQ-ACK signal in a first bandwidth part (BWP), receiving downlink control information (DCI) for switching an active BWP related to a downlink signal from the first BWP to a second BWP, receiving at least one second PDSCH related to the HARQ-ACK signal in the second BWP, and transmitting the HARQ-ACK signal. The HARQ-ACK signal does not include HARQ-ACK information for the at least one first PDSCH.

    Abstract: A disclosure of the present specification provides a random access method for an unlicensed band. The method comprises the steps of: transmitting, by a user equipment (UE), a random access preamble in a first cell of the unlicensed band; and receiving, by the UE, a random access response in a second cell, wherein the second cell may be a first cell, a cell of the unlicensed band, included in a cell group to which the first cell belongs, or a cell of the unlicensed band, included in a timing advance group (TAG) within the cell group, to which the first cell belongs.

    Abstract: One disclosure of the present specification provides a user equipment method. The method comprises the steps of: receiving a time division duplex (TDD) uplink (UL)-downlink (DL) configuration from a frequency division duplex (FDD)-based primary cell; receiving downlink data from at least one secondary cell; determining an uplink subframe of the primary cell to transmit a hybrid automatic repeat request (HARQ) acknowledgement (ACK)/negative-acknowledgement (NACK) for the received downlink data, which is transmitted from the at least one secondary cell, according to the TDD UL-DL configuration; and transmitting the HARQ ACK/NACK from the determined uplink subframe to the primary cell.

    Abstract: Provided are methods and devices for transmitting/receiving downlink signals in a Wireless communication system. Carrier information is provided to user equipment, the carrier information including cell identifier information which indicates Whether a first cell identifier related to a first carrier operating on one resource block (RB) and a second cell identifier used for a cell-specific reference signal (CRS) on the first carrier are the same or different. If the second cell identifier is the same as the first cell identifier, the user equipment assumes that the number of antenna ports for the CRS on the first carrier is the same as the number of antenna ports for a reference signal defined for NB-IoT (reference signal for NB-IoT, NRS). If the second cell identifier is different from the first cell identifier, the carrier information further includes antenna port number information, and the user equipment assumes that the number of the antenna ports for the CRS is the same as the number of antenna ports based on the antenna port number information.

    Abstract: Provided are a method and device for rate matching in a wireless communication system. More specifically, provided is a method for rate matching by user equipment (UE), in new radio access technology (NR), under various circumstances. As an example, UE receives a configuration for the rate matching either UE-specifically or cell-specifically, and, if the configuration is received UE-specifically, the rate matching is performed only on unicast data, and, if the configuration is received cell-specifically, the rate matching is performed on broadcast data and the unicast data.
