Referring to FIG. 16, in step S1610, the base station may transmit information related to SL resource(s) and information related to a UL resource to the transmitting UE. For example, in the case of CG type 1-based resource allocation, the base station may allocate/configure the SL resource(s) and the UL resource to the transmitting UE through an RRC message. For example, in the case of CG type 2-based resource allocation, the base station may allocate/configure the SL resource(s) and the UL resource to the transmitting UE through an RRC message and a DCI. For example, in the case of DG-based resource allocation, the base station may allocate/configure the SL resource(s) and the UL resource to the transmitting UE through a DCI. For example, the SL resource(s) may be resource(s) related to PSCCH transmission and/or PSSCH transmission. For example, the UL resource may be a resource related to PUCCH transmission. For example, the UL resource may be a resource related to PUSCH transmission.
FIG. 17 shows an example of resource allocation based on CG type 1 or CG type 2, based on an embodiment of the present disclosure. The embodiment of FIG. 17 may be combined with various embodiments of the present disclosure.
Referring to FIG. 17, the base station may allocate periodic resources to the transmitting UE through a DCI and/or an RRC message related to a CG.
Referring back to FIG. 16, in step S1620, the transmitting UE may transmit a PSCCH to the receiving UE based on information related to the SL resource(s). In step S1630, the transmitting UE may transmit a PSSCH related to the PSCCH to the receiving UE.
