METHOD BY WHICH RSUS TRANSMIT AND RECEIVE SIGNALS IN WIRELESS COMMUNICATION SYSTEM
Disclosed in one embodiment is a method for performing an operation for a first road side unit (RSU) in a wireless communication system, comprising the steps of: transmitting a first message to a second RSU; and receiving a second message from the second RSU, wherein the first message includes position information and a first position list of the first RSU, the second message includes position information and a second position list of the second RSU, and the first position list is updated with the position information and the second position list of the second RSU.
VIRTUALIZED ROAD TRAFFIC SIGN GENERATION FOR ENHANCING ROAD SAFETY
Systems and methods are described for enhancing road safety via on-demand virtualized road traffic sign generation. A method for generating information for display in a target object (TO) includes: receiving at least one notification message from one or more TOs; generating a situation map for a relevance zone (RZ) based on information in the at least one notification message; encoding an action matrix in a notification message, wherein the action matrix is derived based on the situation map; and transmitting the notification message to the TOs in the RZ. A system includes one or more road side units (RSUs) configured to establish a wireless communication channel with one or more TOs; and a mobile edge computing (MEC) system that includes one or more processors and is configured to implement a virtualized road traffic sign generation service.
Sensor gap analysis
Systems, methods, and computer readable media for performing task assignment, completion, and management within a crowdsourced surveillance platform. A remote server may identify targets for image capture and may assign capture tasks to users based on travel plans of the user. Users may be assigned task to capture image of target locations lying along a travel path. The remote server may aggregate data related to the captured images and use it to update a map and log changes to the target location over time.
Connectivity Matrix for Rapid 5G/6G Wireless Addressing
Vehicles in traffic are expected to communicate wirelessly, to avoid collisions and facilitate the flow of traffic. Unfortunately, in 5G and 6G, the process of finding a wireless address of a specific vehicle is slow and difficult. Disclosed is a “connectivity matrix”, an emblem that vehicles can display, showing a pattern of black and white squares that forms a unique code. Another vehicle can autonomously read the code and look up the wireless address in a tabulation. The tabulation relates each code to the relevant wireless address, and optionally other information about the vehicle. The two vehicles can then transfer messages, including emergency messages, without delay. At freeway speeds, this can save lives. A central entity maintains the tabulation, ensuring that each wireless address is associated with a unique connectivity matrix code. Roadside companies and access points can also display a connectivity matrix, promote communication with prospective customers.
Base station, communication system, communication method, and non-transitory storing medium
A base station includes: a communication circuit configured to communicate with a mobile station; a prediction circuit configured to predict a period during which communication with the mobile station is blocked; and a controller configured to control the communication circuit in such a way that communication data to be transmitted to the mobile station in the period during which communication is blocked are transmitted in a period before the period during which communication is blocked.
METHOD AND APPARATUS FOR HARQ FEEDBACK
Embodiments of the present disclosure relate to method and apparatus for HARQ feedback. According to an embodiment of the present disclosure, a method can include: transmitting, to a first user equipment (UE), location information of a second UE and a communication range required for at least one sidelink transmission from the second UE, wherein each of the at least one sidelink transmission comprises a set of transport blocks (TBs); detecting feedback information associated with a corresponding TB of the set of TBs from the first UE on a set of feedback resources; and determining whether to retransmit the corresponding TB of the set of TBs based on the detection result of the feedback information. Embodiments of the present disclosure can avoid unnecessary retransmission and can improve transmission efficiency in NR V2X groupcast communication.
COMMUNICATION METHODS AND DEVICES IN INTELLIGENT TRANSPORT SYSTEMS
According to some embodiments, there is provided a Collective Perception Message, CPM, characterizing a plurality of Vulnerable Road Users based on a plurality of received VAMs, thereby allowing an ITS station to efficiently aggregate VAM messages from VRUs and retransmit information about the VRUs to other ITS stations. Consequently, the security is improved as some ITS stations may not be able to detect or identify VRU stations by themselves but thanks to the CPM, these stations can still be informed of the VRUs. According to other aspects, congestion is avoided while maintaining safety vis-à-vis VRUs thanks to the use of a different transmission scheme when the VRU is already characterized in a CPM sent to the ITS stations. Also, a receiving station can evaluate whether the content of a CPM can be trusted or not. Safety is thus improved. This is achieved thanks to the CPM that references a certificate.
COLLECTIVE PERCEPTION SERVICE ENHANCEMENTS IN INTELLIGENT TRANSPORT SYSTEMS
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.
Efficient real time vehicular traffic reporting and sharing
In one aspect, an exemplary method for sharing traffic data among a plurality of vehicles includes: a first vehicle receiving current traffic data from at least a second vehicle over a first network protocol; the first vehicle transmitting current traffic data from the first vehicle and the current traffic data received from at least the second vehicle to a roadside unit over a second network protocol; the first vehicle receiving processed traffic data from the roadside unit over the second network protocol, the processed traffic data being based on the current traffic data received from the first vehicle and from at least the second vehicle; and the first vehicle transmitting the processed traffic data received from the roadside unit to at least the second vehicle over the first network protocol.
Methods for Rapid, Precision Position Determination in 5G/6G
Vehicles in traffic cannot coordinate their actions properly in 5G and 6G without knowing the location and the wireless address of the other vehicle. GNSS signals are generally too slow and too imprecise to discern vehicles in, for example, adjacent lanes. Directional wireless beams are subject to reflections from conducting surfaces, producing chaotic signals and false locations if more than one vehicle is within the transmission beam. To provide precise localization in traffic, methods are disclosed for multiple vehicles (or other mobile devices) to acquire satellite signals simultaneously, and then analyze the data differentially, thereby canceling major uncertainties (such as propagation variations, ephemeris motion, and clock jitter), and thereby determining the relative positions precisely. Unlike prior-art “precision” positioning methods, the disclosed methods do not require averaging multiple acquisitions. On the contrary, examples show how high differential precision can be obtained without averaging, using measurements acquired at the predetermined time.
