One-shot transmission for v2x messaging

A method for performing duration-based 1-shot messaging, comprising

• transmitting a sequence of connected messages using Semi-Persistent Scheduling (SPS) of a predefined period;
• setting a random value for a 1-shot duration timer, the random value being chosen as being between a minimum and a maximum multiple of the predefined period;
• and
• responsive to expiration of the 1-shot duration timer, allocating 1-shot resources for a 1-shot transmission, independent of SPS-allocated resources of the SPS, and transmitting a next packet of the sequence of connected messages as a 1-shot message using the 1-shot resources instead of using the SPS-allocated resources of the SPS.

A non-transitory computer-readable medium comprises instructions for performing duration-based 1-shot messaging that, when executed by a controller in communication with a V2X transceiver, cause the controller to perform operations including to:

• transmit a sequence of connected messages using Semi-Persistent Scheduling (SPS) of a predefined period;
• set a random value for a 1-shot duration timer, the random value being chosen as being between a minimum and a maximum multiple of the predefined period;
• and
• responsive to expiration of the 1-shot duration timer, allocate 1-shot resources for a 1-shot transmission, independent of SPS-allocated resources of the SPS, and transmit a next packet of the sequence of connected messages as a 1-shot message using the 1-shot resources instead of using the SPS-allocated resources of the SPS.
