Abstract: The invention relates to an apparatus comprising: at least one processor and at least one memory including a computer program code, the at at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: transmit an indication of device-to-device communications between a plurality of user devices to an access node; receive an information on a configuration for device-to-device control information signaling via the access node, and transmit the device-to-device control signalling according to the informed configuration via the access node.

Abstract: When waking up, a user equipment receives system configuration information in form of an ecoded signal (306). If the code has not changed from its previous value, then the user equipment access the system using the same system configuration information (310) saving effort and time, if the code has changed the UE obtains the whole system information (312) and then carries out the access to the system (314).

Abstract: A method for filtering out a useful signal of a mobile radio terminal from a plurality of superimposed signals having a signal quality received by base stations in a cellular mobile radio network. The superimposed signal of the mobile radio terminal is detected by base stations that are reached and the signal quality of the received and superimposed signal of every base station reached is determined. The signal quality of a selected base station is then transmitted to a decision element and a selection of a selected base station is made by the decision element to decode the useful signal of the mobile radio terminal. The invention also relates to a device for filtering out a useful signal of a mobile radio terminal from a plurality of superimposed signals received by base stations in a cellular mobile radio network.

Abstract: A method for decoding a wireless transmission in a communication system, particularly for mobile communications, comprising a plurality of receiver stations communicatively coupled to a common decoder station, wherein the receiver stations transmit digital representations of received user signals to the common decoding entity. These digital representations are initially transmitted to the common decoder station in coarse granularity, and in case the decoder station cannot decode the transmitted digital representations of one or multiple user signals, the decoder requests a refined digital representation of the received signals from at least one receiver station.
