CV2X situationally-dependent service prioritization
Techniques are providing for situationally-dependent service prioritization in a CV2X network. An example method of prioritizing data packets with a mobile device includes determining a range to a waypoint, determining an estimated time of arrival at the waypoint, computing a priority value based at least in part on the estimated time of arrival at the waypoint, and generating a data packet based on the priority value.
1 . A method of prioritizing data packets with a mobile device, comprising:
determining an estimated time of arrival to a waypoint;
computing a priority value of data packets for transmission over a cellular vehicle to everything (CV2X) data link based at least in part on the estimated time of arrival at the waypoint, wherein a sooner time of arrival corresponds to a higher priority value; and
transmitting a data packet over a CV2X data link based at least in part on the priority value.
2 . The method of claim 1 wherein the waypoint is included in map data received by the mobile device.
3 . The method of claim 1 wherein computing the priority value includes obtaining the priority value from a look-up table based at least in part on the estimated time of arrival.
4 . The method of claim 1 further comprising determining an environmental condition wherein the priority value is based at least in part on the environmental condition.
5 . The method of claim 1 further comprising determining a road condition wherein the priority value is based at least in part on the road condition.
6 . The method of claim 1 wherein the data packet is associated with a long-term evolution communication interface and includes a ProSe Per-Packet Priority value that is based on the priority value.
7 . The method of claim 1 wherein the data packet is associated with a 5G new radio communication interface and includes a PC5 Quality of Service (QOS) Identifier (PQI) value that is based on the priority value.
8 . The method of claim 1 wherein the data packet is associated with a dedicated short-rage communication wireless communication channel.
9 . The method of claim 1 further comprising transmitting the data packet to a roadside unit associated with the waypoint.
10 . The method of claim 1 further comprising transmitting the data packet to a cellular base station.
11 . The method of claim 1 wherein the waypoint is a dynamic waypoint.
12 . The method of claim 11 wherein the dynamic waypoint is an emergency vehicle.
13 . An apparatus, comprising:
at least one memory;
at least one transceiver;
at least one processor communicatively coupled to the at least one memory and the at least one transceiver, and configured to:
determine an estimated time of arrival at a waypoint;
compute a priority value of data packets for transmission over a cellular vehicle to everything (CV2X) data link based at least in part on the estimated time of arrival at the waypoint, wherein a sooner time of arrival corresponds to a higher priority value; and
transmit a data packet over a CV2X data link based at least in part on the priority value.
14 . The apparatus of claim 13 wherein the at least one processor is further configured to receive map data, wherein the waypoint is included in the map data.
15 . The apparatus of claim 13 wherein the at least one processor is further configured to obtain the priority value from a look-up table based at least in part on the estimated time of arrival.
16 . The apparatus of claim 13 wherein the at least one processor is further configured to determine an environmental condition wherein the priority value is based at least in part on the environmental condition.
17 . The apparatus of claim 13 wherein the at least one processor is further configured to determine a road condition wherein the priority value is based at least in part on the road condition.
18 . The apparatus of claim 13 wherein the data packet is associated with a long-term evolution communication interface and the at least on processor is further configured to set a ProSe Per-Packet Priority value based on the priority value.
19 . The apparatus of claim 13 wherein the data packet is associated with a 5G new radio communication interface and the at least one processor is further configured to set a PC5 Quality of Service (QOS) Identifier (PQI) value based on the priority value.
20 . The apparatus of claim 13 wherein the data packet is associated with a dedicated short-rage communication wireless communication channel.
21 . The apparatus of claim 13 wherein the at least one processor is further configured to transmit the data packet to a roadside unit associated with the waypoint.
22 . The apparatus of claim 13 wherein the at least one processor is further configured to transmit the data packet to a cellular base station.
23 . The apparatus of claim 13 wherein the waypoint is a dynamic waypoint.
24 . The apparatus of claim 23 wherein the dynamic waypoint is an emergency vehicle.
25 . An apparatus for prioritizing data packets, comprising:
means for determining an estimated time of arrival at a waypoint;
means for computing a priority value of data packets for transmission over a cellular vehicle to everything (CV2X) data link based at least in part on the estimated time of arrival at the waypoint, wherein a sooner time of arrival corresponds to a higher priority; and
means for transmitting a data packet for transmission over a CV2X data link based at least in part on the priority value.
26 . The apparatus of claim 25 further comprising means for obtaining the priority value from a look-up table based at least in part on the estimated time of arrival.
27 . The apparatus of claim 25 further comprising means for determining an environmental condition wherein the priority value is based at least in part on the environmental condition.
28 . The method of claim 1 further comprising means for transmitting the data packet to a roadside unit associated with the waypoint or means for transmitting the data packet to a cellular base station.
29 . A non-transitory processor-readable storage medium comprising processor-readable instructions configured to cause one or more processors to prioritize data packets, comprising:
code for determining an estimated time of arrival at a waypoint;
code for computing a priority value of data packets for transmission over a cellular vehicle to everything (CV2X) data link based at least in part on the estimated time of arrival at the waypoint, wherein a sooner time of arrival corresponds to a higher priority value; and
code for transmitting a data packet for transmission over a CV2X data link based at least in part on the priority value.
30 . The non-transitory processor-readable storage medium of claim 29 further comprising code for setting a ProSe Per-Packet Priority value or a PC5 Quality of Service (QOS) Identifier (PQI) value based on the priority value.
