    Abstract: According to one embodiment of the present invention, a method of receiving DCI by a UE includes receiving bundling information regarding REGs via higher layer signaling, performing blind detection for a PDCCH in a CORESET configured on a plurality of OFDM symbols, and acquiring DCI from the PDCCH. When the bundling information indicates a first value, the UE may perform bundling such that only REGs locating on a same RB and corresponding to different OFDM symbols in the CORESET, are bundled as 1 REG bundle, and when the bundling information indicates a second value, the UE may perform bundling such that the REGs locating on the same RB and corresponding to the different OFDM symbols are bundled as 1 REG bundle along with REGs locating on different RBs in the CORESET, and the UE may perform the blind detection of the PDCCH by assuming same precoding for REGs belonging to a same REG bundle as a result of REG bundling.

    Abstract: An embodiment of the present invention relates to a method for transmitting a synchronization signal in a wireless communication system. The method comprises: a step of generating a secondary synchronization signal from a combination of two sequences; and a step of transmitting the synchronization signal. The manner of combination of the two sequences varies depending on the sub-frame number to which the secondary synchronization signal is transmitted, and if the generation of the secondary synchronization signal is performed by a terminal, then the sub-frame number which determines the manner of combination is considered to be the same.

    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.
