    CPC classification number: H04L1/1854 H04W76/28 H04W92/18

    Abstract: An embodiment proposes a method for performing wireless communication by a first device. The method may comprise a step of receiving information related to a configured grant (CG) from a base station, the information related to the CG including information related to a hybrid automatic repeat request (HARQ) process ID for the CG, and period information of a resource related to the CG, and transmitting a first transport block to a second device at a first period on the basis of the period information and a first HARQ process ID. For example, on the basis that transmission of the first transport block fails, and the first HARQ process ID and a second HARQ process ID are the same, a discontinuous reception (DRX) timer related to the first transport block may be stopped at a second period related to the second HARQ process ID. For example, DRX related to the first transport block may include DRX between the first device and the base station and DRX between the first device and the second device.

    Abstract: The present disclosure relates to a method of relaying, by a second user equipment (UE), sidelink communication between a first UE and a third UE in a wireless communication system and apparatus therefor. To this end, the second UE may: receive a first sidelink radio resource control (RRC) reconfiguration message from the first UE; transmit a first sidelink RRC reconfiguration complete message to the first UE in response to the first sidelink RRC reconfiguration message; transmit a second sidelink RRC reconfiguration message to the third UE based on the transmission of the first sidelink RRC reconfiguration complete message; monitor a second sidelink RRC reconfiguration result message to be received from the third UE during a running period of a first timer running after the transmission of the second sidelink RRC reconfiguration message; and transmit an RRC connection result notification message to the first UE based on the monitoring of the second sidelink RRC reconfiguration result message.

    CPC classification number: H04W76/14 H04W76/28 H04W92/18

    Abstract: A method for performing wireless communication by a first device and an apparatus supporting the same are proposed. For example, the first device may obtain an SL DRX configuration including information related to an SL DRX cycle and information related to a timer for active time. For example, the timer for active time may include at least one of an SL DRX on-duration timer or an SL DRX inactivity timer. For example, the first device may trigger SL DRX command MAC CE reporting related to the PC5-RRC connection. For example, the first device may cancel the triggered SL DRX command MAC CE reporting, based on an MAC reset for the PC5-RRC connection being requested.
