    Abstract: Disclosed herein is a method of transmitting UL data in a wireless communication system supporting low latency service. The method is performed by an eNB, and includes receiving an urgent signal providing notification of the generation of an event related to an emergency situation from a first UE, determining a point of time at which and/or a section in which an UL grant to be transmitted to a second UE is canceled, wherein the UL grant includes resource allocation information for transmitting, by the second UE, UL data, cancelling the UL grant to be transmitted to the second UE based on a result of the determination, and receiving an urgent message including the detailed information related to the generated event from the first UE.

    Abstract: A method of supporting communication using two or more heterogeneous radio access technologies (RAT) may include receiving, from a first communication network supporting a first RAT, a first message requesting notification as to whether access to a second communication network that simultaneously support the first communication network and a second RAT is supported; transmitting, to the base station in the first communication network, a second message including an indicator indicating whether to support simultaneous access to the first and second communication networks in response to the first message; and receiving a trigger condition for reporting a measurement result for the second communication network from the base station in the first communication network, when the indicator indicates that the terminal is able to access the first and second communication networks.

    Abstract: The present invention relates to a method and apparatus for selecting a cell in a wireless communication system supporting a low latency service. According to the present invention, provided are a method including: receiving a first control message including first scheduling delay information indicating a delay time related with resource allocation of a serving base station from the serving base station; transmitting a request message including an UL (uplink) resource request IE (information element) for requesting UL resource allocation to the serving base station or a neighboring base station; receiving a response message in response to the request message from the serving base station or the neighboring base station; and receiving the UL resource from the serving base station or the neighboring base station based on the request message, in which the UL resource request IE includes an UL grant offset field indicating an UL resource request time of the UE, and an apparatus.

    Abstract: Provided are a method and device for performing channel estimation in a wireless communication system. Specifically, user equipment receives a control channel in the first symbol of a plurality of symbols received for a short TTI (sTTI) set to be shorter than a TTI. The user equipment receives a data channel scheduled by the control channel in the remaining symbols other than the first symbol of the plurality of symbols received in the sTTI. The user equipment receives a user equipment (UE)-specific reference signal having the same frequency resource as a first cell-specific reference signal received in the TTI in the first symbol. The first cell-specific reference signal is received subsequent to the UE-specific reference signal, and the UE-specific reference signal is received in the sTTI. The user equipment decodes the control channel or the data channel using the UE-specific reference signal.
