Abstract: The present invention relates to a method for managing information of on/off small cells in a small cell-based network system and apparatuses for supporting the same. As an embodiment of the present invention, a method for managing information on on/off small cells in a radio access system supporting small cells comprises the steps of: receiving a first message including cell state change information of a first cell corresponding to a small cell, which is changed to an on state or an off state, by a second cell; and transmitting a second message including the cell state change information to a UE by the second cell. At this time, the cell state change information may contain identification information of the first cell, on/off time information indicating a time when change to an on state or an off state is made, and on/off timer information indicating a time interval in which the change to the on state or the off state is made.

Abstract: A method of allocating resources according to the present invention comprises the steps of: allocating a signal having a first beam width from a first base station controlling a first cell to a predetermined resource; and allocating a signal, having a second beam width different from the first beam width, from a second base station controlling a second cell adjacent to the first cell to the resource. The signal having the first beam width may be a signal having a first priority, and the signal having the second beam width may be a signal having a second priority that is different from the first priority. Accordingly, a method for allocating resources is proposed which can stably receive signals even when a terminal that moves in a dense small cell structure is at a cell edge or a border region between cells.

Abstract: A method for providing scalable service in a wireless communication system is disclosed. In this method, the transmitting side device transmits base layer signals and enhancement layer signals for one scalable service to a user equipment (UE) based on a HARQ (Hybrid Automatic Repeat Request) scheme. The base layer signals can be independently used at the UE without the enhancement layer signals. On the other hand, the enhancement layer signals cannot be used at the UE without the base layer signals. The transmitting side device also retransmits the base layer signals before a retransmission of the enhancement layer signals when there are both of the base layer signals and the enhancement layer signals to be retransmitted based on the HARQ scheme.
