1. A method for wireless communication at a first user equipment (UE), comprising:
receiving a first sidelink message over a sidelink channel, the first sidelink message comprising an indication of first resources of the sidelink channel reserved for a fifth sidelink message to a third UE;
transmitting, to a second UE, a second sidelink message over the sidelink channel, the second sidelink message comprising an indication of second resources of the sidelink channel, wherein the second sidelink message indicates that the second resources are available for selection by the second UE for a fourth sidelink message to the first UE or not available for selection by the second UE for the fourth sidelink message;
receiving a third sidelink message from the second UE based at least in part on transmitting the second sidelink message to the second UE, wherein the third sidelink message allocates third resources of the sidelink channel for the fourth sidelink message; and
receiving, from the second UE, the fourth sidelink message over the third resources of the sidelink channel reserved by the second UE based at least in part on transmitting the second sidelink message to the second UE, the fourth sidelink message comprising data for the first UE.
