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 generating a signal for reducing interference in a user-centralized virtual cell, according to an embodiment of the present invention, comprises the steps of: transmitting a reference signal to a terminal within a user-centralized virtual cell; receiving, from the terminal, a first channel measurement report message including channel information measured by the terminal on the basis of the reference signal; exchanging, with the first channel measurement report message, a second channel measurement report message that another base station within the user-centralized cell receives from another terminal other than the terminal, thereby sharing a channel measurement report message with the another base station; and generating a signal for reducing the interference on the basis of the first channel measurement report and the second channel measurement report message.

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.

Abstract: Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.
