摘要： The transmission of data signals transmitted by a plurality of transmitters may be rendered more efficient by combining multi-user superposition coding with appropriate phase shift estimation at the receiver so that phase shift compensation at the transmitter's side may lead to a superposition of the data signals which may be demapped correctly so as to obtain information data per data signal. Owing to the combination, the concept is applicable to typical uplink situations or downlink situations of separate contributing BSs: contrary to the simple downlink situation where the data signals stem from one BS and are superimposed in one domain, namely the base station's domain, the data signals to be superimposed stem from separate transmitters, such as user entities or mobile terminals in the typical uplink situation, or different base stations in the downlink situation.

摘要： A base station for a wireless communication network is provided. The wireless communication network includes a plurality of base stations, each base station to serve one or more users. One or more users are served by a plurality of base stations to receive a first data signal from the base station and a second data signal from at least one further base station using multi-user superposition transmission, MUST. The base station includes a backhaul interface for a communication with one or more of the plurality of base stations of the wireless communication network. For transmitting the first data signal to one or more users served by the base station and by the further base station, the base station is configured to negotiate a MUST setting with the further base station via the backhaul interface, and map data of the first data signal using a first transmit constellation set according to the negotiated MUST setting.

摘要： A wireless communications network includes a base station configured for operating a wireless communications network cell of the wireless communications network so as to provide communication in a plurality of slots. Each slot includes a plurality of associated physical resources. The wireless communications network includes at least one transmitter configured for transmitting a signal in the wireless communications network cell by mapping the signal into a number of part signals and for transmitting the number of part signals with a corresponding number of associated slots using a corresponding number of sets of physical resources, each set containing at least a subset of the associated plurality of physical resources of the slot. Each set of physical resources is received at the base station shifted with a set-individual offset and with respect to a synchronized start of the slot.

摘要： A user device, UE, and a base station, BS, for a wireless communication system is described. Each is using a transmission scheme on a radio resource, and is to determine one or more parameters of a radio channel associated with the radio resource, and to adapt the transmission scheme by selecting an additional radio resource on the basis of the determined one or more parameters. Further a wireless communication system, comprising two or more of the above devices, corresponding methods and a computer program product are described.

摘要： A wireless communication system includes a first transmitter and a second transmitter. For a transmission or reception of data of a first user equipment and data of a second user equipment on resources shared by the first user equipment and the second user equipment, the first transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a first data signal of the first user equipment and a second data signal of the second user equipment, and the second transmitter is configured for a superimposed non-orthogonal multiple access, NOMA, transmission or reception of a third data signal of the first user equipment and a fourth data signal of the second user equipment.
