1. An apparatus for wireless communication at a controller user equipment (UE), comprising:
one or more memories; and
one or more processors, coupled to the one or more memories, configured to cause the apparatus to:
transmit, to a network node, a relay scheduling request that indicates a request to schedule access to a universal mobile telecommunications system air interface (Uu) based at least in part on relaying one or more sidelink retransmissions associated with at least a first sidelink between the controller UE and a first sidelink UE, wherein the relay scheduling request indicates one or more of:
a Uu downlink grant request associated with the controller UE,
a Uu uplink grant request between the controller UE and the network node, or
a joint scheduling request associated with: a first scheduling request for a Uu uplink grant associated with an uplink communication from the controller UE to the network node, and a second scheduling request for at least one Uu downlink grant associated with at least a first downlink communication from the network node to at least the first sidelink UE; and
communicate the one or more sidelink retransmissions between the controller UE and the network node based at least in part on using the Uu.
