Abstract: Methods, computing platforms, storage media, and systems for providing congestion control in Road Side Unit message (“RSU message”) scheduling. One aspect of the present disclosure relates to a method for providing congestion control in RSU message scheduling. Various aspects include measuring a channel busy ratio by a PC5 access layer of a Road Side Unit, comparing the measured channel busy ratio to one or more thresholds, and generating and transmitting RSU messages at a rate determined based upon whether the measured channel busy ratio equals or exceeds the one or more thresholds.

Abstract: 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.

Abstract: Various aspects related to a platooning group in a V2V and/or V2X network are described. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a first UE configured to transmit a first message to announce an existence of the platooning group. In one configuration, the first UE may receive, in response to the first message, a second message indicating a request to join the platooning group from a second UE. The first UE may allow or deny the second UE to join the platooning group based on the second message. In another aspect, the apparatus maybe a first UE configured to receive a first message indicating an existence of a platooning group. The first UE may be configured to decode a portion of the first message, and determine whether the platooning group is a private group based on the decoding.
