Abstract: A method for providing device connectivity to a radio access network, wherein at least two devices are connectable or connected to the radio access network and wherein the at least two devices are members of a group of devices within a wireless local network, the members of the group of devices having the capability to establish a direct connection with other members of the group of devices, includes providing connection information used for a connection between a first device of the at least two devices and the radio access network to a second device of the at least two devices. The connection information enables the second device to connect to the radio access network.

Abstract: A method for resource management in a cellular communication network, wherein said network includes at least one base station per cell for a plurality of cells that operates in TDD (Time Division Duplex) transmission mode, each base station having a respective coverage area is characterized in that said base stations are operated such that spatial zones exist—overlap areas—in which the coverage areas of at least two of said base stations overlap, wherein UEs within an overlap area utilize UL and/or DL resources from those of the respective base stations that best match their particular traffic demands in the UL and/or in the DL. Furthermore, a corresponding resource management system for use in a cellular communication network is disclosed.

Abstract: A method for resource management in a cellular communication network, wherein the network includes at least one base station per cell for a plurality of cells that operates in TDD (Time Division Duplex) transmission mode, wherein the base stations implement a respective UL/DL configuration mode in which frames are composed of a specific sequence of downlink DL, uplink UL and special S subframes, is characterized in that the base stations are operated such that neighboring base stations with adjacent and/or overlapping coverage areas employ different UL/DL configuration modes, wherein interference between neighboring base stations is taken account of by implementing power control on a subframe basis.

Abstract: A method for routing data traffic in a communication network having a source entity, a destination entity, and a plurality of routers for routing the data traffic from the source entity to the destination entity according to link-state-routing according to a shortest-path-first-algorithm, includes transmitting load information of the at least one data traffic interface to a routing management entity and control information, about a low load period of the at least one data traffic interface to the first router (DR), wherein a low load period is related to a data traffic interface of the first router (DR). The method further includes switching, by the first router (DR), into a dosing-state as an energy-saving state during the low load period, and issuing, by the first router (DR) before entering the dosing-state, an operational state message.
