Abstract: 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.

Abstract: A system (1) is configured to select candidate sets of cell groups from a collection of sets of cell groups and arrange transmission of one or more messages to multiple mobile devices (11-15). The one or more messages specify at least one cell group per candidate set of cell groups for each of the mobile devices. The system is further configured to receive responses to the one or more messages. The responses comprise feedback from each of the mobile devices on the specified cell groups.

Abstract: A method is configured for controlling access of nodes to at least two coexisting wireless communication systems, which coexisting wireless communication systems are configured to share a frequency spectrum in a common coverage area. Each node is configured to access at least one wireless communication system in dependence of at least one access parameter. The common coverage area is divided into at least two zones, while each node in the common coverage area is associated with at least one zone.

Abstract: 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.
