Improvements may be made for the congestion control considering different technologies, types of radio resources, and priorities of different packets. The apparatus may be a UE. The UE determines a channel busy ratio (CBR). The UE determines one or more channel resource utilization limits based on the CBR, wherein each channel resource utilization limit of the one or more channel resource utilization limits corresponds to a respective packet priority. The UE controls transmission of a plurality of packets based on the one or more channel resource utilization limits, each packet of the plurality of packets being associated with a respective packet priority.
