Abstract: 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.

Abstract: A method implemented by a first device to share at least one resource element within a wireless communication network, the resource element belonging to a first set of radio resources allocated to the first device within a resource pool, the first device using a device-to-device communication within the wireless communication network, and wherein the first device emits, through the device-to-device communication, an indication that the resource element is available for sharing.

Abstract: The radio frequency resource is shared between the first device and at least one second device connected to a second radio access network. The first device first obtains information representative of a usage of the radio frequency resource by the second device. Then, it obtains a threshold value of a collision rate acceptable for the second device. It determines a value representative of an estimated collision rate as experienced by the second device for at least one frequency resource allocation of the first device from the obtained information representative of the usage of said radio frequency resource by said second device. Finally, the first device uses the at least one frequency resource allocation for the first device in the case where the determined value is below the obtained threshold value.

Abstract: 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.
