    Abstract: The present specification proposes a method for transmitting and receiving a plurality of PDCCHs in a wireless communication system, and a device therefor. Specifically, a method performed by a base station comprises: a step for receiving, from a UE, UE capability information indicating the number of beams that can be simultaneously supported; a step for transmitting independent layer joint transmission (ILJT)-related setting information to the UE; and a step for transmitting the plurality of PDCCHs to the UE on the basis of the ILJT-related setting information, wherein the ILJT-related setting information may be determined on the basis of the UE capability information.

    Abstract: A method and apparatus for transmitting signals on a PUSCH in a wireless communication system are provided. Specifically, a method performed by a terminal includes receiving resource information for transmitting uplink data and channel state information (CSI) on a PUSCH from a base station; receiving first downlink control information (DCI) including control information on slot timing related to the uplink data transmission from the base station; comparing a first time related to computation of the uplink data and CSI and a second time related to computation of only the CSI; and transmitting, if a value of the slot timing is greater than the second time and smaller than the first time, only the CSI on the PUSCH to the base station.

    Abstract: Disclosed is a method by which a terminal reports channel quality information (CQI) to a base station in a multi-antenna-based wireless communication system. Particularly, the method comprises the steps of: receiving, through an upper layer, the reference signal configuration defined by P number of antenna ports; receiving, through M number of antenna ports, reference signals from the base station; grouping the P number of antenna ports into antenna port groups formed of the M number of antenna ports; calculating CQIs by using the reference signal corresponding to each of the antenna port groups on the basis of the assumption that predefined precoders are applied to the reference signals; and reporting, to the base station, N number of CQIs among the calculated CQIs.

    Abstract: A method for receiving a downlink signal by a user equipment (UE) from an eNB in a wireless communication system is disclosed. In detail, the method comprises the steps of receiving a downlink control channel from the eNB; and receiving, from the eNB, a downlink data channel and a front loaded reference signal for demodulation of the downlink data channel by using control information included in the downlink control channel, wherein resource elements of symbols to which a front loaded reference signal is received are identified by two multiplexing groups or three multiplexing groups, and the downlink control channel includes information on a multiplexing group, to which the front loaded reference signal is allocated, among the multiplexing groups, and information on the number of multiplexing groups, to which data are not allocated, among the multiplexing groups.
