Abstract: Apparatus and methods are provided to support discontinuous channel/SCI monitoring (DRX) over Sidelink in mobile communication system. In one novel aspect, when a V2X-UE would like to perform sidelink communication with its peer UE, but does not know whether its peer UE is monitoring SCI or is in non-active time (e.g. turn off the radio for PC5 interface), UE send a ping message to check the status of its peer UE. If there is no response to the ping message, the UE assumes that its peer UE is not in active time, and therefore postpone the sidelink communication until the start of the next sidelink on duration of its peer UE. In another novel aspect, a UE is configured with a specific monitoring channel and/or time-frequency resource before UE start SCI monitoring period. If in the specific monitoring resource the UE does not detect signal from any UE to wake him up, the UE can skip the following SCI monitoring period until the next resource for wake-up signal detection.
