Abstract

A user device and transportation entity, such as a transport vehicle or transport server, perform information exchanges for a transportation service using Device-to-Device (D2D) communications, such as dedicated short-range communication (DSRC), a cellular Vehicle-to-Everything (C-V2X), or a 5G New Radio (NR). The information exchanges, for example, are related to, e.g., logistics and delivery of transportation services. For example, the user device may transmit a transportation request message that includes information elements, such as an identifier, a type of transport device requested, a number of users, requested destination, etc. The transportation entity may transmit a transportation response message accepting or rejecting the request. Additional messages, such as a status request and status of the transportation, as well as messages related to completing the transportation service may be exchanged.

First claim

What is claimed is:

1. A method of wireless communication at a user device, comprising:
broadcasting a transportation request message to a transportation entity wirelessly, wherein the transportation request message comprises a first set of message information elements including an identifier for the user device and a requested destination;
receiving a transportation response message broadcasted by the transportation entity wirelessly, wherein the transportation response message comprises a second set of message information elements including acceptance or rejection of the transportation request message;
transmitting a transportation confirm message to the transportation entity wirelessly in response to the acceptance in the transportation response message, wherein the transportation confirm message comprises a third set of message information elements including the identifier for the user device;
broadcasting a transportation status request message to the transportation entity wirelessly, wherein the transportation status request message comprises a fourth set of message information elements including a query for information related to a current location; and
receiving a transportation status message broadcasted by the transportation entity wirelessly, wherein the transportation status message comprises a fifth set of message information elements including information related to the current location.

2. The method of claim 1 , wherein the first set of message information elements in the transportation request message further comprises at least one of a type of transport device requested, a number of users, a validity time for the transportation request message, a maximum travel time or required destination arrival time, or a combination thereof.

3. The method of claim 1 , further comprising determining an estimate of arrival to the requested destination using the information related to the current location.

4. The method of claim 1 , wherein the fourth set of message information elements in the transportation status request message further includes the identifier for the user device, a query for information related to an estimate of arrival to the requested destination, and wherein the fifth set of message information elements in the transportation status message further includes the estimate of arrival to destination.

5. The method of claim 4 , wherein the estimate of arrival to destination comprises one or more of estimated time of arrival to destination and estimated number of stops to destination, and wherein the fifth set of message information elements in the transportation status message further includes a destination of a transport vehicle nearest the requested destination.

6. The method of claim 1 , further comprising:
broadcasting a transportation complete request message to the transportation entity wirelessly, wherein the transportation complete request message comprises a sixth set of message information elements including the identifier for the user device, and a request to disembark;
receiving a transportation complete acknowledgement message broadcasted by the transportation entity wirelessly, wherein the transportation complete acknowledgement message comprises a seventh set of message information elements including an estimate of arrival to destination and a confirmation of the request to disembark; and
receiving a transportation complete response message broadcasted by the transportation entity wirelessly, wherein the transportation complete response message comprises an eighth set of message information elements including the identifier for the user device, and including at least one of an ingress location, an egress location, a fare and a request to provide periodic signals to validate that the user device has exited a transport vehicle.

7. The method of claim 1 , further comprising:
transmitting a transport registration message to the transportation entity, wherein the transport registration message includes a payment method to be charged for transport; and
receiving a first acknowledgement message for the transportation registration message from the transportation entity based on the transport registration message, wherein the transportation request message is broadcasted to the transportation entity based on the first acknowledgement message.

8. The method of claim 7 , further comprising:
transmitting a deregistration message to the transportation entity, wherein the deregistration message completes a purchase based on the payment method.

9. An apparatus for wireless communication at a user device, comprising:
a memory; and
at least one processor coupled to the memory and configured to:
broadcast a transportation request message to a transportation entity wirelessly, wherein the transportation request message comprises a first set of message information elements including an identifier for the user device and a requested destination;
receive a transportation response message broadcasted by the transportation entity wirelessly, wherein the transportation response message comprises a second set of message information elements including acceptance or rejection of the transportation request message;
transmit a transportation confirm message to the transportation entity wirelessly in response to the acceptance in the transportation response message, wherein the transportation confirm message comprises a third set of message information elements including the identifier for the user device;
broadcast a transportation status request message to the transportation entity wirelessly, wherein the transportation status request message comprises a fourth set of message information elements including a query for information related to a current location; and
receive a transportation status message broadcasted by the transportation entity wirelessly, wherein the transportation status message comprises a fifth set of message information elements including information related to the current location.

10. The apparatus of claim 9 , wherein the first set of message information elements in the transportation request message further comprises at least one of a type of transport device requested, a number of users, a validity time for the transportation request message, a maximum travel time or required destination arrival time, or a combination thereof.

11. The apparatus of claim 9 , wherein the fourth set of message information elements in the transportation status request message further includes the identifier for the user device, a query for information related to an estimate of arrival to the requested destination, and wherein the fifth set of message information elements in the transportation status message further includes the estimate of arrival to destination.

12. The apparatus of claim 11 , wherein the estimate of arrival to destination comprises one or more of estimated time of arrival to destination and estimated number of stops to destination, and wherein the fifth set of message information elements in the transportation status message further includes a destination of a transport vehicle nearest the requested destination.

13. The apparatus of claim 9 , wherein the at least one processor is further configured to:
transmit a transport registration message to the transportation entity, wherein the transport registration message includes a payment method to be charged for transport; and
receive a first acknowledgement message for the transportation registration message from the transportation entity based on the transport registration message, wherein the transportation request message is broadcasted to the transportation entity
