Abstract: A method for transmitting a signal that includes the steps of: determining the beam width of a beam to be transmitted; determining, on the basis of the beam width, relative narrowband transmit power (RNTP) information indicating whether a transmission power of at least a predetermined critical value is transmitted to a predetermined resource block; transmitting the RNTP information to an adjacent cell; and transmitting the generated beam to the resource block according to the RNTP information. Also provided is a method for configuring an RNTP value for controlling inter-cell interference in a communication system.

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.

Abstract: Provided are a method and a device for generating a virtual bearer in a wireless communication system. A mobility management entity (MME) acquires context information for a packet data network (PDN) connection generated through a Wi-Fi network, and generates a virtual bearer in a cellular network on the basis of the acquired context information. The virtual bearer may be generated by various methods according to whether a PDN connection mapped to the PDN connection generated through the Wi-Fi network exists in the cellular network and whether a default bearer exists in the cellular network.

Abstract: A method for providing scalable service in a wireless communication system is disclosed. In this method, the transmitting side device performs initial transmission of base layer signals to a user equipment (UE) based on a HARQ (Hybrid Automatic Repeat Request) scheme, and performs transmission of enhancement layer signals to the UE after finishing the initial transmission of the base layer signals. The base layer signals and the enhancement layer signals are for one scalable service. The base layer signals can be independently used at the UE without the enhancement layer signals, while the enhancement layer signals cannot be used at the UE without the base layer signals. The transmitting side device further performs retransmission of the base layer signals determined to be retransmitted based on the HARQ scheme while performing the initial transmission of the enhancement layer signals.
