Abstract: A method and device for transmitting a transport block in a wireless communication system is provided. Particularly, a terminal receives, from a base station, information on the number of subcarriers in a partial band included in an allocated carrier. The terminal distributes a soft buffer possessed by the terminal in proportion to the number of subcarriers in the partial band. The terminal determines a transport block size for each partial band according to the size of the distributed soft buffer. The terminal transmits, to the base station, the transport block within the transport block size.

Abstract: Provided are method and device for transmitting/receiving a downlink signal. A user equipment-specific reference signal (UE-RS) can be transmitted to a user equipment. A downlink control channel and a downlink data channel for the user equipment can share the UE-RS. Antenna port information about a transmission antenna port of the downlink control channel and/or a transmission antenna port of the downlink data channel is provided to the user equipment. The user equipment receives UE-RS(s) corresponding to the antenna port information and thus receives the downlink control channel and the downlink data channel.

Abstract: Provided are a method and an apparatus for obtaining downlink synchronization in a wireless communication system. The wireless communication system that is proposed has an environment in which the resource location of a downlink synchronization signal changes due to the application of multiple numerology. Particularly, a terminal receives synchronization signal information from a base station. The synchronization signal information includes candidate resources from which synchronization signals with respect to a tracking area can be transmitted, and the order of detecting the synchronization signals from the candidate resource win respect to the tracking area. The terminal detects the synchronization signal on the basis of the synchronization signal information.

Abstract: The present invention relates to a method and an apparatus for generating a signal for low latency in a wireless communication system. The method, according to one embodiment of the present invention, for a communication device generating a situation-reporting signal for low latency and transmitting the signal to a base station in a wireless communication system comprises the steps of: generating the situation-reporting signal on the basis of a pre-set, specific situation recognized by the communication device; and transmitting the generated situation-reporting signal to the base station, wherein the situation-reporting signal may be generated so as to have a subcarrier spacing which is a pre-set number of times larger than a subcarrier spacing of a legacy communication system, the pre-set number being an integer.

Abstract: The present invention relates to a method and an apparatus for transmitting and receiving data in a wireless communication system which supports a low latency service. According to the present invention, a method and an apparatus are provided, wherein a terminal transmits a request message to a base station for converting from an idle state to a connected state; receives, from the base station, a response message including the resource information associated with the transmission and reception of low latency service data, in response to the request message; and transmits and receives the low latency service data using an allocated resource. Thereafter, when additional data is generated, the terminal converts from an idle state to a connected state and transmits and receives the additional data.

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.
