Abstract: A method and an apparatus for transmitting/receiving a downlink signal in a wireless communication system are provided. Carrier information about a second carrier that is different from a first carrier can be transmitted on the first carrier. Downlink data for UE can be transmitted on the second carrier based on the carrier information. The first carrier is a carrier having a synchronisation signal and a physical broadcast channel, and the second carrier can be a carrier without any synchronisation signals or physical broadcast channels. The first carrier can be operated on a single resource block in a guard frequency that is used in the wireless communication system.

Abstract: A method for receiving a Physical Downlink Shared Channel (PDSCH) in a user equipment (UE) from a base station (BS) in a wireless communication system includes the UE receiving first information related to one or more control resource set (CORESET); receiving second information related to resource region of the PDSCH; receives the PDSCH based on the second information; and receiving a demodulation reference signal (DMRS) for the PDSCH in an orthogonal frequency divisional multiplexing (OFDM) symbol after the one or more CORESET when the one or more CORESET overlaps the resource region of the PDSCH.

Abstract: The present disclosure relates to a wireless access system supporting an unlicensed band, and provides methods for transreceiving discovery reference signals and devices supporting same. A method for a terminal receiving a discovery reference signal (DRS) in a wireless access system supporting an unlicensed band, according to one embodiment of the present disclosure, may comprise the steps of: receiving an upper layer signal including parameters indicating a multimedia broadcast multicast service single frequency network (MBSFN) subframe; receiving a setting for a discovery measurement timing configuration (DMTC) section, which is a time section during which the DRS can be transmitted; and receiving the DRS within the DMTC section, wherein when a first subframe belonging to the DMTC section is configured as the MBSFN subframe and the DRS is transmitted from the first subframe, an MBSFN configuration may not be applied to the MBSFN subframe.

Abstract: Provided are a method and apparatus for transmitting/receiving single cell point to multipoint (SC-PTM) data. Time-frequency resources for the SC-PTM can be set. A frequency resource that may have downlink control information (DCI) scrambled with a corresponding group identifier for each group identifier available in a cell may be set. A time resource, which may have a DCI scrambled with the corresponding group identifier for each group identifier available in the cell, may be set.
