Abstract: Provided are a method and an apparatus for receiving a downlink signal in a wireless communication system. The method includes receiving resource block assignment information including a bitmap and receiving the downlink signal through a resource block group (RBG) indicated by the bitmap in a bandwidth part. A total number of resource block groups (RBGs) in the bandwidth part is determined based on an index of a start resource block of the bandwidth part, a size of the bandwidth part, and a size of one resource block group.

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.

Abstract: A method by which a terminal receives a downlink control channel in a wireless communication system is disclosed. Particularly, the method monitors candidate physical downlink control channels (PDCCHs) composed of control channel elements (CCEs), the number of which corresponds to an aggregation level, so as to receive a PDCCH, wherein CCEs for candidate PDCCHs of a higher aggregation level include all of the CCEs for candidate PDCCHs of a lower aggregation level, and the CCEs for candidate PDCCHs of the lower aggregation level included in each of the candidate PDCCHs of the higher aggregation level can be determined using a matrix on the basis of the magnitude of the higher aggregation level and the number of the candidate PDCCHs of the higher aggregation level.

Abstract: A method of monitoring a control signal in a wireless communication system, where the method is performed by a user equipment (UE) and includes: selecting at least one control resource set (CORESET) among a plurality of CORESETs based on an overlap between physical downlink control channel (PDCCH) monitoring occasions in the plurality of CORESETs; and monitoring a PDCCH only in the selected at least one CORESET, among the plurality of CORESETs. The method also includes: based on the at least one CORESET including a first CORESET, and based on a first reference signal of the first CORESET and a second reference signal of a second CORESET being associated with a same synchronization signal/physical broadcast channel block (SSB): monitoring the PDCCH in both the first CORESET and the second CORESET.

Abstract: The present invention relates to a method and apparatus for measuring channel status information on a terminal in a wireless communication system that supports the change of usage of a radio resource. In particular, the method includes the steps of: receiving a change of usage message for a dynamic change in the usage of a radio resource; and measuring channel status information (CSI) from a CSI reference resource, wherein the CSI reference resource is arranged on a time section at which a usage of a radio resource is determined by the change of usage message, and determined based on only an uplink-downlink setting on a system information block (SIB) when the reception of the change of usage message is unsuccessful.

Abstract: The method for reception of a signal by a terminal in a wireless communication system according to an embodiment of the present invention may comprise a step of monitoring control channel candidates on the basis of information on precoding granularity. Specifically, even if information on the precoding granularity instructs to the terminal to assume that the reference signal with respect to the control channel candidates is mapped to all resource element groups (REGs) included in consecutive resource blocks in the first control resource set, when some of the consecutive resource blocks overlap with a second control resource set set by a physical broadcasting channel (PBCH), the terminal may not assume that the reference signal with respect to the control channel candidates is mapped to the REGs included in some resource blocks which are overlapping.
