    Abstract: A method of receiving downlink data in a wireless communication system and a wireless device are provided. The wireless device determines energy per resource element (EPRE) of a reference signal that is received in a transmission bandwidth of an orthogonal frequency division multiplexing (OFDM) symbol and determines the power ratio of the EPRE of the reference signal to the EPRE of a Physical Downlink Shared Channel (PDSCH) on the basis of the transmission bandwidth. The wireless device determines the EPRE of the PDSCH on the basis of the EPRE of the reference signal and the power ratio and demodulates the PDSCH.

    Abstract: Provided is a method by which a first apparatus performs wireless communication and an apparatus for supporting the method. The method comprises the steps of: receiving, from a base station, information related to a sidelink (SL) bandwidth part (BWP); receiving, from the base station, information related to an uplink (UL) BWP; receiving, from the base station, information related to an SL resource and information related to a UL resource for reporting a hybrid automatic repeat request (HARQ) feedback; transmitting, on the basis of the SL resource within the SL BWP, data in which the HARQ feedback has been disabled to a second apparatus through a physical sidelink shared channel (PSSCH); generating an ACK related to the transmission of the data in which the HARQ feedback has been disabled; and transmitting, to the base station, the ACK on the basis of the UL resource within the UL BWP.

    Abstract: In one embodiment, a method by which a first device performs wireless communication is proposed. The method may comprise the steps of: determining at least one first candidate slot for selecting a first sidelink (SL) resource; performing sensing of at least one first slot related to the at least one first candidate slot; and selecting the first SL resource in the at least one first candidate slot on the basis of the sensing. For example, a first channel busy ratio (CBR) related to the at least one first slot may be measured on the basis of the number of the at least one first slot that is greater than or equal to a first threshold value.
