Based on an embodiment of the present disclosure, an apparatus configured to control a first user equipment (UE) performing wireless communication may be provided. For example, the apparatus may comprise: one or more processors; and one or more memories operably connected to the one or more processors and storing instructions. For example, the one or more processors may execute the instructions to: receive, from a base station, information related to a physical uplink control channel (PUCCH) resource for reporting hybrid automatic repeat request (HARQ) feedback information and information related to a configured grant (CG) resource for sidelink (SL); generate ACK information, based on no physical sidelink control channel (PSCCH) transmission by the first UE on the CG resource in a single period; and determine a priority value of the ACK information. For example, the priority value of the ACK information may be same as a largest priority value among at least one possible priority value related to the CG resource.
Based on an embodiment of the present disclosure, a non-transitory computer-readable storage medium storing instructions may be provided. For example, the instructions, when executed, may cause a first device to: receive, from a base station, information related to a physical uplink control channel (PUCCH) resource for reporting hybrid automatic repeat request (HARQ) feedback information and information related to a configured grant (CG) resource for sidelink (SL); generate ACK information, based on no physical sidelink control channel (PSCCH) transmission by the first device on the CG resource in a single period; and determine a priority value of the ACK information. For example, the priority value of the ACK information may be same as a largest priority value among at least one possible priority value related to the CG resource.
