Discontinuous reception for sidelink control signaling

A wireless device, comprising:

• one or more processors configured with processor-executable instructions to:
• monitor for a wake-up indication from a base station using a radio of the wireless device;
• monitor, based on detecting the wake-up indication from the base station, for sidelink control signaling from the base station using the radio of the wireless device during a sidelink control signaling monitoring duration, wherein monitoring for the sidelink control signaling from the base station using the radio of the wireless device during the sidelink control signaling monitoring duration comprises monitoring for a Control Resource Set (CORESET) for the sidelink control signaling and monitoring for a CORESET for base station link control signaling based on the wake-up indication indicating to monitor for both the sidelink control signaling and the base station link control signaling, wherein the wake-up indication comprises a field for sidelink control signaling and a field for base station link control signaling or the wake-up indication comprises a field to indicate joint signaling;
• receive the sidelink control signaling, wherein the sidelink control signaling allocates a sidelink communication resource and schedules a sidelink communication;
• perform the scheduled sidelink communication based on the received sidelink control signaling;
• and
• place the radio of the wireless device into a low power mode outside of the sidelink control signaling monitoring duration when no sidelink communication is scheduled.
