INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract One embodiment provides a method for performing an operation for a first terminal in a wireless communication system, wherein: in an on-duration period, a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) is monitored; on the basis of reception of at least one sidelink traffic indication indicating that there is sidelink data to be transmitted from a second terminal, a physical sidelink shared channel (PSSCH) including second SCI is monitored; and on the basis of non-reception of at least one sidelink traffic indication indicating that there is sidelink data to be transmitted from the second terminal, the PSSCH including the second SCI is not monitored. The first UE communicates with at least one of another UE, a UE related to an autonomous driving vehicle, or a base station (BS), or a network. ## Claims ### Claim 1 A method of performing an operation for a first user equipment (UE) in a wireless communication system, the method comprising: monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section; based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI; and based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI. ### Claim 2 (depends on 1) The method of claim 1, wherein whether the second SCI is for the first UE based on the second SCI is determined. ### Claim 3 (depends on 1) The method of claim 1, wherein, based on that a source L1 identifier included in the second SCI is the same as a unicast destination L1 identifier of the first UE or a destination L1 identifier included in the second SCI is the same as a unicast source L1 identifier of the first UE, the second SCI is determined to be for the first UE. ### Claim 4 (depends on 1) The method of claim 1, wherein, based on that a groupcast/broadcast destination L1 identifier included in the second SCI is the same as a groupcast/broadcast destination L1 identifier of the first UE, the second SCI is determined to be for the first UE. ### Claim 5 (depends on 1) The method of claim 1, wherein the sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, and based on that there is no sidelink data to be transmitted to the second UE, the first UE operates in a sleep mode before the on-duration section ends. ### Claim 6 (depends on 1) The method of claim 1, wherein, based on the first SCI and the second SCI, a PSSCH including the sidelink data is received. ### Claim 7 (depends on 1) The method of claim 1, wherein a sidelink discontinuous reception (DRX) on-duration timer is operated in the on-duration section. ### Claim 8 A first user equipment (UE) in a wireless communication system, comprising: at least one processor; and at least one computer memory operatively connected to the at least one processor and configured to store commands that when executed causes the at least one processor to perform operations, wherein the operations include: monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section; based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI; and based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI. ### Claim 9 (depends on 8) The first user equipment (UE) of claim 8, wherein the first UE communicates with at least one of another UE, a UE related to an autonomous driving vehicle, or a base station (BS), or a network. ### Claim 10 A processor for performing operations for a base station (BS) in a wireless communication system, the operations comprising: monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section; based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI; and based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI. ### Claim 11 A computer readable storage medium storing at least one computer program that includes a command that, when executed by at least one processor, causes the at least one processor to perform operations for a first user equipment (UE), the operations comprising: monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section; based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI; and based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI.
