Procedure and signaling for sidelink drx alignment

An apparatus for wireless communication, comprising:

• a memory comprising executable instructions;
• and
• one or more processors configured to execute the executable instructions and cause the apparatus to:
• receive, from a network at a first user equipment over an air interface, discontinuous reception (DRX) configuration assistance information;
• transmit, from the first user equipment to a second user equipment via a sidelink interface, the DRX configuration assistance information;
• receive, 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;
• transmit, from the first user equipment to the network over the air interface, the sidelink DRX configuration information;
• and
• receive, from the network at the first user equipment, modified air interface DRX configuration information for the first user equipment.

A non-transitory computer-readable medium for wireless communication, comprising:

• executable instructions that, when executed by one or more processors of an apparatus, cause the apparatus to:
• receive, from a network at a first user equipment over an air interface, discontinuous reception (DRX) configuration assistance information;
• transmit, from the first user equipment to a second user equipment via a sidelink interface, the DRX configuration assistance information;
• receive, 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;
• transmit, from the first user equipment to the network over the air interface, the sidelink DRX configuration information;
• and
• receive, from the network at the first user equipment, modified air interface DRX configuration information for the first user equipment.
