Abstract: Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.

Abstract: Disclosed is a method for radio link monitoring in a wireless communication system and an apparatus for the method. More specifically, a method for a user equipment (UE) to perform Radio Link Monitoring (RLM) in a wireless communication system comprises performing second RLM on a cell based on a Reference Signal (RS) other than a Cell-specific Reference Signal (CRS) and determining an Radio Link Failure (RLF) with respect to the cell based on the second RLM, wherein a condition for determining an RLF applied to the second RLM is different from the condition for determining an RLF applied to CRS-based first RLM.

Abstract: A method is provided for receiving a downlink signal through an Enhanced Physical Downlink Control Channel (EPDCCH) in a wireless communication system by a user equipment (UE). The UE receives a parameter indicating a quasi co-location behavior type is. The UE further receives a demodulation reference signal (DMRS) associated with the EPDCCH. The UE attempts to decode the EPDCCH based on the DMRS. If a transmission mode configured in the UE is a transmission mode 10, the UE assumes that antenna ports of the DMRS are quasi co-located with antenna ports of a reference signal determined by the parameter.

Abstract: A method for receiving, by a base station, channel state information (CSI) in a wireless communication system. The method includes receiving, from a user equipment (UE), UE capability information related to at least one of channel state information-reference signal (CSI-RS) resources or CSI-RS ports; transmitting, to the UE, CSI-RS configuration information that includes information based on the UE capability information; transmitting, to the UE, a CSI-RS using at least one CSI-RS port based on the CSI-RS configuration information; and receiving, from the UE, the CSI, wherein the CSI is based on a measurement, for the CSI-RS, performed by the UE. Further, the UE capability information includes information for i) a maximum number of the CSI-RS resources and ii) a maximum number of the CSI-RS ports related to number of the CSI-RS resources configured based on the maximum number of the CSI-RS resources.

Abstract: A method for transmitting an SRS by a terminal may comprise the steps of: receiving, from a base station, information on a first bandwidth part (BWP) and a second BWP set for SRS transmission of the terminal; and when a frequency starting position for SRS transmission in the second BWP having a lower priority than the first BWP overlaps the first BWP, transmitting the SRS to the base station at an SRS bandwidth position different from an SRS bandwidth position associated with the frequency starting position for the SRS transmission. 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: The present specification provides a method for receiving data on the basis of quasi co-location (QCL) in a wireless communication system. More particularly, a data reception method performed by means of a terminal comprises the steps of: receiving transmission configuration indication (TCI) state information relating to at least one QCL indication with respect to a downlink reference signal (DL RS) from a base station by means of RRC signaling; receiving a physical downlink control channel (PDCCH), comprising downlink control information (DCI), on a first slot from the base station; and receiving a physical downlink shared channel (PDSCH) comprising data from the base station on the basis of one or more QCL indications. Therefore, the flexibility of the terminal during beam switching can be enhanced.
