    Abstract: A method for reporting channel status information (CSI) to a base station by a terminal in a wireless access system is disclosed in the present application. The method for reporting CSI comprises the steps of: receiving information on a first CSI process and a second CSI process, each of which includes two or more CSI-reference signal (CSI-RS) resources, through an upper layer; and transmitting, to the base station, a first CSI report according to the first CSI process and a second CSI report corresponding to the second CSI process, wherein the second CSI process is configured to have a rank indicator (RI) value that is the same as the RI of the first CSI process, and the numbers of antenna ports for all the CSI-RS resources included in the first CSI process and the second CSI process are the same.

    Abstract: A method is provided for receiving a user equipment (UE) specific reference signal based-downlink data channel by a UE in a wireless communication system. The UE receives, from a network, a downlink control channel including either first scheduling information or second scheduling information, and receives the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. When the downlink control channel includes the first scheduling information, antenna ports of a certain reference signal which can be assumed to be quasi co-located with antenna ports of a UE-specific reference signal is configured by an indicator indicating one of two or more parameters configured by a higher layer. When the downlink control channel includes the second scheduling information, the antenna ports of a certain reference signal is configured by a parameter of a minimum index among the two or more parameters.

    Abstract: A method for generating an SRS sequence by a terminal may comprise the steps of: calculating a first root value for generation of an SRS sequence of a first block among concatenated blocks configured for transmission of an SRS, using a terminal-specific SRS identifier; calculating a second root value for generation of an SRS sequence of a second block on the basis of the calculated first root value and a root offset value; and generating an SRS sequence for transmission of an SRS on the concatenated blocks by applying the first root value to the first block and applying the second root value to the second block.
