Abstract

The present disclosure is related to Intelligent Transport Systems (ITS), and in particular, to service dissemination basic services (SDBS) and/or collective perception service (CPS) of an ITS Station (ITS-S). Implementations of how the SDBS and/or CPS is arranged within the facilities layer of an ITS-S, different conditions for service dissemination messages (SDMs) and/or collective perception message (CPM) dissemination, and format and coding rules of the SDM/CPS generation are provided.

First claim

1 - 42 . (canceled)

43 . An apparatus in an Intelligent Transportation System Station (ITS-S), the apparatus comprising:
memory circuitry to store instructions of a service dissemination basic service (SDBS) facility in a facilities layer of the ITS-S; and processor circuitry connected to the memory circuitry, wherein the processor circuitry is to operate the SDBS to:
generate a service dissemination message (SDM) to include a set of service dissemination (SD) containers;
communicate with at least one other facilities layer entity operated by the ITS-S to piggyback the SDM with another facilities layer service message generated by the at least one other facilities layer entity;
cause transmission or broadcast of the SDM piggybacked with the other facilities layer service message.

44 . The apparatus of claim 43 , wherein the set of SD containers includes an SD management container to carry information indicating a type of originating ITS-S (station Type), a location of the originating ITS-S(referencePosition), and a number of SD data containers (numberofDataContainers) in the SDM.

45 . The apparatus of claim 44 , wherein the set of SD containers includes a station data container to carry one or more of:
information indicating an intersection reference identifier (ID) and road segment reference ID when the originating ITS-S is a roadside ITS-S(R-ITS-S) or a relatively stationary station other than an R-ITS-S; information indicating a heading and a speed when the originating ITS-S is a vehicle ITS-S(V-ITS-S) or a vulnerable road user (VRU) station; and information indicating a service type, wherein the service type indicates whether the originating ITS-S is requesting SD or providing SD and whether a class or category associated with the SD data.

46 . The apparatus claim 44 , wherein the set of SD containers includes an SD data container to carry:
an SD data type; an SD identifier (ID), wherein the SD ID is one of: an SD consumer ID identifying an SD consumer or an SD vendor ID identifying an SD vendor; an SD lifetime; an SD data length; and the SD data, wherein the SD data has a variable length or size based on an associated SD or subscription data associated with the SD ID.

47 . The apparatus of claim 43 , wherein the other facilities layer service message is one or more of:
a cooperative awareness message (CAM) generated by a collaborative awareness basic service (CABS) facility, a signal phase and timing service (SPATS) message generated by a SPATS facility, a VRU awareness message (VAM) generated by a vulnerable road user basic service (VRUBS) facility, a collective perception message (CPM) generated by a collective perception service (CPS) facility, a Decentralized Environmental Notification Message (DENM) generated by a DEM basic service facility, and a local dynamic map (LDM) message generated by an LDM facility.

48 . The apparatus of claim 43 , wherein, to cause transmission or broadcast of the SDM, the processor circuitry is to operate the SDBS to:
cause transmission or broadcast of the SDM in an opportunistic fashion; and/or cause transmission or broadcast of the SDM according to a duty cycle of a service message over which the piggybacking of the SDM occurs when a traffic load of a transmission medium is below a threshold.

49 . The apparatus of claim 48 , wherein the processor circuitry is to operate the SDBS to:
obtain a traffic load indication from a Decentralized Congestion Control (DCC) facility in the facilities layer, wherein the traffic load indication indicates the traffic load of the transmission medium; and adjust an SDM generation frequency and transmission duty cycle based on the traffic load indication.

50 . The apparatus of of claim 43 , wherein the ITS-S is a V-ITS-S or a VRU ITS-S, and the processor circuitry is to operate the SDBS to:
activate or deactivate the SDBS based on one or more of one or more user inputs, one or more user preferences, and user subscription data.

51 . The apparatus of claim 50 , wherein the processor circuitry is to operate the SDBS to:
receive another SDM via a network and transport layer of the ITS-S; and provide other SD data from the other SDM to an SD application in an applications layer of the ITS-S for output of the other SD data.

52 . The apparatus of claim 51 , wherein, to output the other SD data, the processor circuitry is to operate the SD application to one or both of:
cause rendering and display content based on the other SD data; and cause generation and output of one or more audio signals based on other SD data.

53 . The apparatus of of claim claim 43 , wherein the ITS-S is an R-ITS-S, and the processor circuitry is to operate the SDBS to:
activate the SDBS when the R-ITS-S is powered on; and deactivate the SDBS the R-ITS-S is powered off.

54 . The apparatus of claim 53 , wherein, to cause transmission or broadcast of the SDM, the processor circuitry is to operate the SDBS to:
obtain context information from one or more of a position and time management (PoTi) facility, a DCC facility, and a facilities layer admission control (DCC-FAC) facility, wherein the context information comprises one or more of a time of day, detected or measured environmental conditions, receiving station types in an environment surrounding the ITS-S, system information of the ITS-S, and operational parameters of the ITS-S; and cause transmission or broadcast of the SDM based on the context information.

55 . The apparatus of claim 53 , wherein the processor circuitry is to operate the SDBS to:
collect usage data based on the transmitted or broadcasted SDM and one or more received SDMs; and provide the usage data to an external system.

56 . The apparatus of claim 43 , wherein the processor circuitry is to operate the SDBS to:
obtain sensor data indicating zero or more perceived objects; and generate the SDM to include a layered costmap, wherein the layered costmap includes a plurality of layers, the plurality of layers include a parking status layer, and the parking status layer includes cost values associated with the zero or more perceived objects in one or more parking spaces.

57 . One or more non-transitory computer-readable media (NTCRM) comprising instructions for operating a service dissemination basic service (SDBS) facility in a facilities layer of an Intelligent Transportation System Station (ITS-S), wherein execution of the instructions by one or more processors of the ITS-S is to cause the ITS-S to:
obtain sensor data indicating zero or more perceived objects; generate a service dissemination message (SDM) to include a layered costmap, wherein the layered costmap includes a plurality of layers, the purality of layers include a parking status layer, and the parking status layer includes cost values associated with the zero or more perceived objects in one or more parking spaces; and cause transmission of the SDM to a remote system.

58 . The one or more NTCRM of claim 57 , wherein execution of the instructions is to cause the ITS-S to:
