Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a channel occupancy ratio for each of one or more proximity service priority levels. The UE may identify a resource availability metric and a message requirement metric for each of the one or more proximity service priority levels, the second protocol layer being a higher layer than the first protocol layer. The UE may determine a message generation rate for each of the one or more proximity service priority levels based on the channel occupancy ratio, or the resource availability metric, or the message requirement metric, or a combination thereof. The UE may generate one or more messages for each of the one or more proximity service priority levels based on the message generation rate.
