Patent number: 11665260Abstract: A first system (11) is configured to transmit an interest message, e.g. to a router (21). The interest message specifies criteria identifying data units from an area of interest, e.g. an intersection, which are to be aggregated and comprises at least one parameter specifying how the data units are requested to be aggregated. A second system (1) is configured to receive the interest message from a sender, e.g. a router (21), determine whether the system will return an aggregation of data units matching the criteria, and return a data message comprising an aggregation of data units matching the criteria to the sender (21) if the processing means have determined that the system will return an aggregation of data units matching the criteria. The data units are aggregated in the data message in dependence on how the data units were requested to be aggregated.Type: GrantFiled: April 13, 2018Date of Patent: May 30, 2023Assignees: Koninklijke KPN N.V., Nederlandse Organisatie voor Toegepast-Natuurwetenschappelijk Onderzoek TNOInventors: Konstantinos Trichias, Lucia D'Acunto, Bastiaan Wissingh, Ray Van Brandenburg, Thomas Attema

Publication number: 20170331758Abstract: One or more wireless communication systems may coexist at about the same geographical location and be configured to access the same radio channel. The coexistence of these systems may cause collisions and degrade throughput. Although countermeasures, such as reserving airtime with a resource assignment, may be taken to avoid collisions, these countermeasures are degrading throughput as well. The reserved airtime is reduced by adding a start time to the resource assignment. The reduced airtime may be used by others for performing a transmission, thus increasing the throughput and efficiency of the access to the radio channel.Type: ApplicationFiled: May 9, 2017Publication date: November 16, 2017Inventors: Konstantinos Trichias, Haibin Zhang
