Techniques for sidelink resource reservations

An apparatus for wireless communication at a first user equipment (UE), comprising:

• at least one processor;
• at least one memory coupled with the at least one processor;
• and
• instructions stored in the at least one memory and executable by the at least one processor to cause the apparatus to:
• transmit, to a second UE and within an active duration of a first sidelink discontinuous reception pattern of the second UE, sidelink control information indicating a resource reservation for a sidelink resource of a sidelink channel within at least a portion of an inactive duration of the first sidelink discontinuous reception pattern, wherein transmission of the sidelink control information indicating the resource reservation of the sidelink resource within the inactive duration is based at least in part on a resource availability within the active duration failing to satisfy a threshold resource availability;
• and
• communicate, with the second UE via the sidelink channel, a sidelink message within the sidelink resource of the sidelink channel within at least the portion of the inactive duration indicated in the resource reservation.
