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: The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for a terminal to report channel state information in a wireless communication system, the method comprising: a step of transmitting first channel state information according to a first channel state information (CSI) process for reporting the first channel state information periodically for every first period; a step of transmitting second channel state information according to a second CSI process for reporting the second channel state information periodically for every second period; and a step of dropping the transmission of either the first channel state information or the second channel state information on the basis of the CSI process index of each of the first and second CSI processes in the event the first channel state information transmission timing and the second channel state information transmission timing conflict.

Abstract: A method and a user equipment (UE) for receiving, and a method and a base station (BS) for transmitting a UE specific reference signal based-downlink data channel in a wireless communication system are discussed. The method for receiving a UE specific reference signal based-downlink data channel according to an embodiment includes receiving a downlink control channel from a network; and receiving the UE-specific reference signal based-downlink data channel from the network based on the downlink control channel. The downlink control channel includes an indicator indicating one of two or more parameters configured by a higher layer. The two or more parameters indicate antenna ports of a certain reference signal which is assumed to be quasi co-located with antenna ports of a UE-specific reference signal.

Abstract: The present invention provides a method and a device for transmitting or receiving channel state information (CSI). According to the present invention, when a user equipment can be set with one or more CSI processes per serving cell, a CSI request field included in downlink control information for a specific serving cell indicates at least whether a non-periodic CSI report triggered by the CSI request field is triggered for a set of CSI process(es) set by a higher layer from among the CSI process(es) for the one serving cell.
