According to some embodiments of the disclosure, it is provided a method of communication in an intelligent transport system, ITS. After having perceived an object within an area monitored by the ITS-S, at a first given time, an estimation of a state of the object is obtained at a second given time, if the object is no longer perceived by the ITS-S at the second given time and a Collective Perception Message, CPM, comprising items of information related to the estimated state of the object is transmitted.

Communication within an intelligent transport system for signaling hidden objects

A communication method for an Intelligent Transport System (ITS) comprising at least one first transmitting ITS station, the method taking place at the first transmitting ITS station including transmitting a second Collective Perception Message (CPM) comprising at least one identifier of a first element previously transmitted in a first CPM, the first element being not present in the second CPM.

Enhanced reporting in CPM based on layered cost map

The present invention regards Cooperative Intelligent Transportation Systems, C-ITS. In response to detecting at least one situation involving at least one object detected within an area monitored by the ITS, a Collective Perception Message, CPM, is generated and transmitted. The CPM comprises a reference to the at least one object and an indication to indicate that the at least one object is involved in the at least one situation.

Communication within an intelligent transport system

A communication device in a communication network according to the invention comprises: a signal processing unit configured to demodulate symbols of a received digital signal into payload data to be provided to a data processing unit through an interfacing link, e.g. a MAC/PHY interface, the received digital signal being made of raw data; a bandwidth determining module configured to determine available bandwidth in a transmission slot allocated to one symbol of the received digital signal for transmitting corresponding payload data through the interfacing link; a sampler configured to select raw data from the received digital signal that correspond to the determined available bandwidth; and a multiplexer configured to combine the selected raw data with the payload data corresponding to the one symbol into the same transmission packet to be provided to the data processing unit through the interfacing link.

Communication devices in a communication network and methods for processing data in such devices

An image processing device processes a first sub-image of an image split into sub-images. Each sub-image is displayable by a display device. The image processing device is associated with a first display device and connects to a source device through a first network and to another image processing device through a second network. The image processing device includes first and second receiving units and a generating unit. The first receiving unit receives the first sub-image from the source device via the first network. The second receiving unit receives, via a second network, at least one part of at least one second sub-image to be displayed by another display device, wherein the received at least one part is adjacent to the received first sub-image. The generating unit generates a first clustered sub-image to be displayed by the first display device, based on the received first sub-image and adjacent part.

A method is proposed for managing communications in a wireless network in which a first communication is set up or established on a plurality of carriers between a first sender device and a receiver device, the network comprising a set of at least one second sender device for which a second communication has to be established simultaneously with said first communication. Such a method comprises steps of:

A method of controlling data transmission from a transmitting unit to a receiving unit through an asynchronous serial link is provided. The method is performed by a controlling unit and includes the steps of sequentially receiving data and synchronization messages are sequentially received from the transmitting unit; sequentially parsing the messages received; and when a message parsed is a synchronization message, blocking relaying to the receiving unit, of the data messages following said synchronization message, until an event associated with the synchronization message occurs.

Time sensitive transaction over an asynchronous serial link

A method of controlling the data rate of a data transmission between an emitter and a receiver, wherein data rate adaptation control commands may be sent using a return path from the receiver to the emitter, which comprises monitoring at least one receiving condition at the receiver; determining at least one threshold on said receiving conditions to trigger data rate adaptation control commands; estimating the transmission time of the data rate adaptation control commands from the receiver to the emitter and adjusting the threshold on these receiving conditions to trigger data rate adaptation control commands based on said estimation of the transmission time from the receiver to the emitter. Accordingly, by continuously adjusting at least one said triggering threshold according to the variation of the transmission time of said data rate adaption commands, a more efficient data rate adaptation method is obtained minimizing the adaptation needs.

The present invention relates to a method for managing communications in a wireless communications network having a mesh or 'relay-based' communication mode operating according to a relay scheme. The network includes network devices defining transmission links between them. The method includes initially detecting a mobile obstacle within the network coverage area; dynamically tracking the detected obstacle by iteratively determining a monitoring area including the detected obstacle; selecting, from the transmission links, a subset of monitoring links belonging at least partly to the monitoring area and monitoring a perturbation level of the selected monitoring links to determine movement of the mobile obstacle in the coverage area; and dynamically adapting the relay scheme of the network based on the belonging or not belonging of the transmission links between network devices to the selected subset.
