Abstract

According to one embodiment of the present invention, the method for receiving a channel state information (CSI)-reference signal (RS) from a wireless communication system by a user device comprises the steps of: receiving resource configuration information on the CSI-RS; and receiving the CSI-RS on the basis of the resource configuration information on the CSI-RS, wherein the resource configuration information on the CSI-RS includes information on a cell specific-RS (CRS) related to the CSI-RS, and the user device can assume that an antenna port related to information on the CRS and an antenna port used for transmitting CSI-RS corresponding to the resource configuration information on the CSI-RS are quasi co-located.

Description

technical field [0001] The present invention relates to a wireless communication system. In particular, the present invention relates to a method for reporting channel state information, a supporting method thereof, and a device for the method. Background technique [0002] Recently, various devices requiring machine-to-machine (M2M) communication and high data transmission rates, such as smartphones or tablet personal computers (PCs), have emerged and are widely used. This dramatically increases the amount of data that needs to be processed in cellular networks. In order to meet such rapidly increasing data throughput, recently, carrier aggregation (CA) technology that effectively utilizes more frequency bands, cognitive radio technology, multi-antenna (MIMO) technology for increasing data capacity in limited frequencies, multiple Base station cooperation technology and so on have received attention. Additionally, communication environments have evolved such that the den...
