    Abstract: Disclosed is a method for a terminal for transceiving a signal with a base station in a wireless communication system. Specifically, the method comprises the steps of: receiving, from the base station, information regarding one or more extended subbands by means of a base subband; transmitting a random access preamble to the base station by means of a particular extended subband from among the base subband or one or more extended subbands; receiving, from the base station, a random access response corresponding to the random access preamble by means of the particular extended subband; and transmitting an uplink signal and receiving a downlink signal by means of the particular extended subband, wherein the base subband and said one or more extended subbands differ from each other by one or more from among the subcarrier spacing, unit scheduling time, and bandwidth.

    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: Disclosed is method and apparatus for communication using common feedback information in multiple antenna system. According to this method, a receiving side device receives rank Ni signals from a transmitting side device with a first type multiple antenna transmission scheme at a first receiving opportunity, and receives rank Nj signals from the transmitting side device with a second type multiple antenna transmission scheme at a second receiving opportunity, where Ni>Nj. The feedback information of this method is common feedback information comprising a combination of a first feedback information for the rank Ni signals and a second feedback information for the rank Nj signals. For this, the first type multiple antenna transmission scheme uses the second type multiple antenna transmission scheme for transmission of rank Nj signals among the rank Ni signals received at the first receiving opportunity.

    Abstract: The present disclosure provides a method and apparatus for performing an operation related to a Radio Link Failure (RLF) in a wireless communication system. Particularly, the method performed by a user equipment (UE) includes monitoring a radio link state of a serving base station (BS); detecting a physical layer problem; transmitting a specific random access preamble related to the RLF to one or more neighboring BSs through a specific Physical Random Access Channel (PRACH) resource; receiving a random access response from the one or more neighboring BSs; determining a neighboring BS to which an additional RRC connection is to be configured based on the received random access response; and configuring an RRC connection with the determined neighboring BS, wherein the specific PRACH resource is a common PRACH resource that is separately configured to transmit the specific random access preamble, thereby preventing the Link Outage phenomenon of the UE for a specific service.

    Abstract: Disclosed are a method and a device for determining a cell identifier. A method for determining a cell identifier can comprise the steps of: a network control unit generating an Nth neighbor cell list which comprises information about a neighboring cell of a search cell; the network control unit receiving, from a search cell, information about a global cell identifier and a first PCI of an unknown cell; the network control unit determining whether or not the unknown cell is a moving cell on the basis of the global cell identifier; and, if the unknown cell is a moving cell and the first PCI and a second PCI of a neighbor cell that is comprised in the Nth neighbor cell list, the network control unit transmitting to the moving cell a PCI change signal that requests changing of the first PCI.
