Abstract: A method for transmitting channel status information (CSI) via uplink in a wireless communication system includes transmitting a first precoding matrix indicator (PMI) and a second PMI at a subframe. A subsampled codebook for each of a precoding codebook for Rank-1 and a precoding codebook for Rank-2 is determined based on at least the first PMI or the second PMI. In case of the Rank-1 or the Rank-2, a number of elements for the first PMI is 8.

Abstract: The present invention relates to a wireless communication system and, more specifically, to a method and device for reporting channel state information (CSI). The method by which a terminal in a wireless communication system reports CSI, according to one embodiment of the present invention, can comprise the steps for: receiving a reference signal from a base station; and reporting, to the base station, the CSI generated by using the reference signal. When the CSI for a two-dimensional antenna structure defined by a first domain and a second domain includes a channel quality indicator (CQI) for the two-dimensional antenna structure without including a precoding matrix indicator (PMI) for the two-dimensional antenna structure, the CQI can be calculated on the basis of the tilting in the second domain.

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.
