Abstract: A method for estimating transmitted signals transmitted from a plurality of transmitters, the method comprising: simultaneously receiving at each of a plurality of receivers a respective received signal resulting from the transmitted signals; determining for each receiver a set of equation coefficients; forming for each received signal a characterisation of that received signal composed of elements weighted in accordance with the equation coefficients determined for the receiver at which that received signal was received; and processing the characterisations to estimate the transmitted signals; wherein the equation coefficients are determined such that the characterisations are substantially linearly independent.

Abstract: The present disclosure refers to base stations, user equipments and a system for wireless communication, as well as the corresponding wireless communication methods implementing mechanisms enabling fast, reliable and resource efficient retransmissions between a base station and one or a plurality of user equipments. The present disclosure is specifically directed to an uplink unicast case and a downlink multicast case and cooperates a proactive allocation of resources for a retransmission of the initial data in case that the initial data transmission fails, and a new data transmission if the initial data transmission successes.

Abstract: A relay device for operating in a communication system that comprises at least two individual networks. The networks may be “individual” in the sense that they are different from each other. Different networks comprise different functionalities. In particular, different networks will tend to operate in different spectrum, have separate authorization and/or authentication procedures and/or apply different transmission technologies. Each network comprises a network device and a remote device that are configured to wirelessly transfer data between them. The relay device is configured to receive data transmitted by a device in a first one of the networks over a first section of radio spectrum. It is also configured to transmit that data to a device in a second one of the networks over a second section of radio spectrum that is different from the first section of radio spectrum.

Abstract: A device is provided for operating in a communication system that comprises a plurality of individual networks. The device comprises one or more subscriber modules for assisting the device to attach to a network. The number of those one or more subscriber modules is fewer than the number of the plurality of networks. The device being configured to initiate a pre-attach procedure to attach itself to all of the plurality of networks before it establishes a connection with one of those networks. It is also configured to connect to one of the plurality of networks for communicating data with that network while remaining attached to the others of the plurality of networks. The advantage of a device that pre-attaches to more than one network is that it significantly reduces the time needed for the device to switch later from being connected to one network to another network.

Abstract: Embodiments of the present disclosure provide a Radio-resource management (RRM) configuration device, and corresponding method, for a network comprising a plurality of access nodes. The device is configured to divide the plurality of access nodes of the network into clusters, and to select at least one access node of each cluster as RRM controller. Further, the device is configured to determine the non-selected access nodes of each cluster as slave nodes, and to select, for each cluster, an RRM split between each slave node and the at least one RRM controller of the respective cluster. The device is also configured to transmit, to each access node, information about its cluster, the at least one RRM controller of the cluster, and the selected RRM split.
