Abstract: A method of receiving, by a user equipment (UE), a reference signal in a wireless communication system. The method includes: receiving downlink control information (DCI) for scheduling downlink data in a first transmission time interval (TTI); acquiring, from the DCI, information related to whether the reference signal is included in the first TTI in which the downlink data is scheduled; and receiving, in the first TTI, the reference signal for the first TTI based on the information related to whether the reference signal is included in the first TTI. The method further includes, based on the downlink data scheduled to be repeatedly transmitted in the first TTI and at least one second TTI: receiving, in each of the at least one second TTI, a reference signal for the each of the at least one second TTI.

Abstract: The present disclosure provides a method for a terminal to receive downlink control information (DCI) in a wireless communication system. Particularly, the method is characterized in that DCI is received through one or more control channel elements (CCE) based on an aggregation level for a physical downlink control channel (PDCCH), wherein each of the one or more CCEs includes a plurality of resource element groups (REG), each of the plurality of REGs includes a plurality of resource elements (RE), and the DCI is mapped to a first RE included in a first REG and then to a second RE included in a second REG.

Abstract: The present invention provides a method by which a terminal receives downlink control information (DCI) in a wireless communication system. Particularly, the method can acquire the DCI by detecting a plurality of first DCI candidates in a plurality of control resource block (RB) sets, descrambling a cyclic redundancy check (CRC) included in each of the plurality of first DCI candidates, and aggregating second DCI candidates, from among the plurality of first DCI candidates, descrambled on the basis of the same scrambling sequence.

Abstract: An embodiment of the present invention provides a method for transmitting a plurality of packets by a sidelink terminal in a wireless communication system, the method comprising the steps of: transmitting a first packet of a plurality of packets with a first period and a first transmission power value; and transmitting a second packet of the plurality of packets with a second period and a second transmission power value, wherein the first period is longer than the second period, and the first transmission power value is greater than the second transmission power value. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, the BS or a network.

Abstract: A method for transmitting/receiving data in a wireless communication system and a device for supporting same are presented. Particularly, a method by which a terminal receives a physical downlink shared channel (PDSCH) in a wireless communication system comprises the steps of: receiving, from a base station, downlink control information (DCI) for scheduling the PDSCH in a nth transmission time unit; and determining whether the PDSCH is received on the basis of the DCI, wherein the DCI includes information for indicating whether a demodulation reference signal (DMRS) for the PDSCH exists in the nth transmission time unit.

Abstract: Provided herein are a method for performing wireless communication by a first apparatus and an apparatus for supporting the same. The method may include the steps of receiving a configuration related to a Uu bandwidth part (BWP) from a base station, and receiving a configuration related to a sidelink (SL) BWP from the base station. Herein, based on a numerology of the Uu BWP and a numerology of the SL BWP being different, the first apparatus may not perform SL communication on the SL BWP.

Abstract: Disclosed are a method for performing an initial access in a wireless communication system, and an apparatus therefor. Specifically, a method by which a terminal performs an initial access comprises the steps of: receiving, from a base station, configuration information representing one or more physical random access channel (PRACH) configurations; receiving, from the base station, downlink control information including information indicating a specific PRACH configuration among the one or more PRACH configurations, through a physical downlink control channel; and transmitting a preamble and/or data, which are related to the initial access, to the base station through a PRACH on the basis of the specific PRACH configuration.
