Abstract: A method for transmitting downlink by a network node. The network node creates downlink data for a terminal which is in a radio resource control (RRC) idle state. The network node inserts the downlink data into a first paging message for transitioning the terminal to an RRC connected state, when a size of the downlink data is smaller than a reference value. In addition, the network node transmits the first paging message to the terminal through a base station.

Abstract: A method in which a base station manages information for D2D communication, which is direct communication between terminals, is provided. The base station receives a first message that requests a configuration of a first open discovery service that searches for a first terminal and at least one terminal to perform D2D communication. The base station determines whether a resource to allocate to the first terminal exists. The base station stores first information for providing the first open discovery service based on the determination result.

Abstract: A method of providing a physical cell identity (PCI) assignment by a management server for small-cell base stations (BSs) in a heterogeneous network environment includes setting a location coordinate and radius for the small-cell BSs; grouping every first preset number of small-cells together to define one femto zone; constructing a location map for each femto zone; grouping every second preset number of femto zones to define one femto group; and constructing a location map for each femto group.
