A method for allocating a radio resource in a system comprising a resource scheduler and a set of devices is disclosed. Each device hosts at least one application, each application transmitting messages to at least one receiver on a transmission channel. The resource scheduler first receives, from each application, application parameters representative of application's requirements. Then, it computes, for each application, a metric responsive to at least part of the received application parameters, to an average probability of failure of said application and further to a channel error probability of said transmission channel. The metrics are compared and, responsive to said comparison, it selects the application to allocate the radio resource to. The average probability of failure each application is further updated. Finally, it transmits an instantaneous probability of failure to each application, said instantaneous probability of failure being used by said application to update its application parameters.

Method and device for allocating radio resource

A method evaluates channel information of a database, DB, the DB channel information being associated to a target area and being representative of expected characteristics of a wireless communication channel in the target area to be provided to one or more communication devices. The method includes: obtaining, by a processing circuit, all or part of the DB channel information from the database; obtaining, by the processing circuit, observed channel information representative of characteristics of the wireless communication channel experienced by a first communication device in the target area; computing, by the processing circuit, a reliability indicator for the DB channel information for the target area, by comparing the DB channel information and the observed channel information and determining a timing information for the reliability indicator.

Method for evaluating channel information of database, communication device, database, and wireless communication system

Examples include a method to communicate between a first and a second synchronized mobile devices, the method comprising sensing a plurality of preconfigured radio resources and identifying for each sensed preconfigured radio resource, whether it is occupied. The method also comprises receiving an indication of future occupied preconfigured radio resource utilization by further mobile devices in the spatial domain, and selecting a specific pre-configured radio resource reducing or preventing communication collisions in the spatial domain. The method further comprises the first and the second mobile devices communicating using the selected specific preconfigured radio resource.
