Abstract: A resource allocation method according to the present invention may comprise the steps of: allocating a signal of an external resource to a predetermined resource according to a preconfigured resource allocation frame structure by a first base station governing a first cell; allocating a signal of an internal resource to the resource according to the resource allocation frame structure by a second base station governing a second cell adjacent to the first cell; and frequency-hopping the signal of the internal resource by the second base station when the signal of the internal resource overlaps the signal of the external resource. Accordingly, proposed is a resource allocation method capable of stably receiving a signal even when a terminal moving in a dense small cell structure is located at a cell edge, that is, an inter-cell boundary area.

Abstract: Provided are a method and a device for arranging a subframe structure of a short TTI according to the change in a control region in a wireless communication system. Specifically, a plurality of first downlink channels received during an sTTI and a second downlink channel received during a TTI are received. The number of symbols used for each of the plurality of first downlink channels is determined by a format indicator channel included in the first symbol of a subframe. Further, the plurality of first downlink channels are demodulated by using scheduling information included in each of the plurality of first downlink channels, and the second downlink channel is demodulated by using scheduling information included in a control region indicated by the format indicator channel.

Abstract: The present invention relates to a method for multi-RAT scheduling, and an apparatus therefor, in a heterogeneous wireless communication system. A cellular controller, which controls a terminal in a cellular network, receives a multi-RAT buffer status report from a terminal, determines a UL resource for each corresponding heterogeneous wireless communication network, transmits a multi-RAT BSR response message corresponding to the buffer status report to the terminal, and allocates the UL resource to the terminal by means of the heterogeneous wireless communication network.

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: Provided are a method and device for performing channel estimation in a wireless communication system. Specifically, user equipment receives a control channel in the first symbol of a plurality of symbols received for a short TTI (sTTI) set to be shorter than a TTI. The user equipment receives a data channel scheduled by the control channel in the remaining symbols other than the first symbol of the plurality of symbols received in the sTTI. The user equipment receives a user equipment (UE)-specific reference signal having the same frequency resource as a first cell-specific reference signal received in the TTI in the first symbol. The first cell-specific reference signal is received subsequent to the UE-specific reference signal, and the UE-specific reference signal is received in the sTTI. The user equipment decodes the control channel or the data channel using the UE-specific reference signal.
