1. A method for wireless communication at a source user equipment (UE), comprising:
transmitting, from the source UE to a set of relay UEs, a resource reservation message that indicates a first set of resources for a source UE communication from the source UE to the set of relay UEs, and a second set of resources for one or more relay transmissions of the source UE communication from the set of relay UEs to a destination UE, wherein the first set of resources are groupcast sidelink resources for a groupcast sidelink communication from the source UE to the set of relay UEs, and the second set of resources are cooperative multiple-input multiple-output resources for cooperative multiple-input multiple-output sidelink communications from the set of relay UEs to the destination UE; and
transmitting the source UE communication to the set of relay UEs in the groupcast sidelink communication using the first set of resources.
