Certain aspects of the present disclosure provide techniques for air interface and sidelink discontinuous reception alignment for inactive/idle user equipment. A method performed by a user equipment (UE) includes receiving, from a network at a first user equipment over an air interface, discontinuous reception (DRX) configuration assistance information, and transmitting, from the first user equipment to a second user equipment via a sidelink interface, the DRX configuration assistance information. The method may further include receiving, from the second user equipment at the first user equipment via the sidelink interface, sidelink DRX configuration information, wherein the sidelink DRX configuration information is based on the DRX configuration assistance information, and transmitting, from the first user equipment to the network over the air interface, the sidelink DRX configuration information. The method may include receiving, from the network at the first user equipment, modified air interface DRX configuration information for the first user equipment.
