Abstract: According to the present invention, a first physical downlink control channel (PDCCH) and a second PDCCH can be transmitted to user equipment. A first physical downlink data channel (PDSCH) corresponding to the first PDCCH, and a second PDSCH corresponding to the second PDCCH can be transmitted to the user equipment. When the first PDSCH has a lower decoding priority than the second PDSCH, and the decoding timing of the first PDSCH and the decoding timing of the second PDSCH overlap, the user device may decode the second PDSCH and not the first PDSCH at the decoding timing, and transmit information with respect to the first PDSCH as first ACK/NACK information. As a reply to the first ACK/NACK information, a third PDCCH not having a corresponding PDSCH may be transmitted to the user equipment.

Abstract: Disclosed herein are a method and apparatus for transmitting/receiving random access signals. A user equipment (UE) transmits a random access preamble of a random access procedure through a random access channel (RACH) resource associated with a synchronization signal (SS) block. A base station (BS) receiving the random access preamble from a UE can transmit CSI-RSs to the UE. The BS may inform the UE that there will be CSI-RS transmission to the UE, during the random access procedure.

Abstract: The present disclosure provides a method for transmitting a random access channel (RACH) by a UE in a wireless communication system. Particularly, the method includes receiving information about actually transmitted synchronization signal blocks (SBBs) and RACH configuration information about RACH resources and transmitting a RACH in at least one RACH resource among RACH resources mapped to actually transmitted SSBs on the basis of the information about actually transmitted SSBs and the RACH configuration information, wherein the actually transmitted SSBs are repeatedly mapped to RACH resources by a positive integer multiple of the number of the actually transmitted SSBs in a RACH configuration period based on the RACH configuration information.

Abstract: The present invention discloses a method for a terminal to receive a synchronization signal in a wireless communication system. Particularly, the method includes the steps of receiving a synchronization block including a primary synchronization signal (PSS), a secondary synchronization signal (SSS), and a physical broadcasting channel (PBCH) and receiving a DMRS (demodulation reference signal) via resource region in which the PBCH is received. In this case, an index of the synchronization block can be determined in consideration of a sequence of the DMRS.
