9. A method for wireless communication, comprising:receiving a request-to-send (RTS) message from a wireless device during a shortened transmission time interval (TTI) reserved for use for priority communications to or from a vehicle having a first traffic priority level, the shortened TTI having a duration that is less than that of other TTIs used in other communications to or from the vehicle having a second traffic priority level which is less than the first traffic priority level, the RTS message indicating an identifier and a configuration for the priority communications during the shortened TTI, wherein the configuration for the priority communications comprises an indication of whether the RTS is a control RTS or a control-less RTS;
identifying a sequence based at least in part on the RTS message;
transmitting a clear-to-send (CTS) message indicating the sequence and using a set of resource blocks (RBs) having a same number of RBs as is used for the RTS message, wherein the sequence associates the CTS message with the RTS message; and
performing the priority communications with the wireless device from which the RTS message was received.
