    Abstract: Disclosed in the present application is a method for transmitting, by a terminal, an uplink signal to a base station through a plurality of antenna ports in a wireless communication system. Specifically, the method comprises the steps of: transmitting, to the base station, uplink reference signals corresponding to the plurality of antenna ports and antenna port grouping information: receiving, from the base station, information on an uplink precoder, which is determined on the basis of the uplink reference signals and the antenna port group information; precoding the uplink signal using the information on the uplink precoder; and transmitting the precoded uplink signal to the base station, wherein the antenna port grouping information comprises information on antenna port groups comprising the plurality of antenna ports and information of the signal distortion level between the antenna port groups.

    Abstract: The present invention relates to signal transmission and reception method and device by an equipment which is dual-connected to a first radio access technology (RAT) and a second RAT in a wireless communication system. The method comprises the steps of: a first signal in accordance with a first RAT and a second signal in accordance with a second RAT being scheduled separately timewise; and transmitting and receiving the first signal and the second signal. The operation for the second signal is determined on the basis of whether or not the second signal reception is scheduled in a first time domain for transmitting the first signal. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.
