Abstract: A method for performing Carrier Aggregation (CA) using spectrum shared between an incumbent user and a telecommunications network includes establishing a primary cell (PCell) for the secondary user in a portion of radio spectrum that is exclusively licensed to the telecommunications network, establishing a secondary cell (SCell) for the telecommunications network in a portion of the shared spectrum that is shared with the incumbent user, receiving schedule data for the incumbent user at a controller in communication with the incumbent user and a transmitter for the PCell and the SCell, scheduling transmissions for the PCell and the SCell to avoid interference to the incumbent user, and transmitting the scheduled transmissions through the PCell and the SCell using Carrier Aggregation (CA). Accordingly, one or more SCell in shared spectrum may be aggregated with a PCell in dedicated spectrum.

Abstract: In one embodiment, a device in an anchorless network receives an update message from a first neighbor of the device. The update message indicates a movement of a node in the network to a new position in the network. The device updates a forwarding table of the device to reverse a link direction associated with the node, in response to receiving the update message. The device sends the update message to a second neighbor of the device towards a prior position of the node in the network.

Abstract: Methods and systems are provided for using virtual base stations in communication systems. A communication system may comprise a plurality of fixed base stations. A virtual base station may be generated and/or assigned to a fixed base station in the communication system, with the fixed base station emitting signals of the virtual base station. The communication system may also comprise at least one network node, and communication system may be configured to transmit data of the virtual base station between the at least one network node and the assigned fixed base station, and emit signals of the virtual base station from the assigned fixed base station with the transmitted data of the virtual base station. The data of the virtual base station may be transmitted from the network node over multicast and/or broadcast connections, to the assigned fixed base station and to one or more fixed base stations.

Abstract: A method and apparatus for scheduling short uplink transmissions on a mobile communication device. Embodiments of the invention include a method of scheduling an uplink transmission on a mobile communication device. In one exemplary embodiment, the method includes establishing a predetermined uplink delay time, and generating an uplink message. The method further includes determining that an audio event is occurring on the mobile communication device, and monitoring an audio amplitude of the audio event. The method further includes transmitting the uplink message when the first of either a pause in the audio event is detected or when the predetermined uplink delay time has elapsed.

Abstract: Embodiments of the present disclosure disclose a data retransmission communication method and a terminal for implementing inter-base station carrier aggregation, where the method includes: receiving, by a first Radio Link Control (RLC) entity of a terminal, a packet data unit PDU; and when the first RLC entity determines that the PDU reaches a maximum quantity of retransmissions, instructing, by the first RLC entity, a second RLC entity of the terminal to transmit the PDU, where the first RLC entity is corresponding to a first base station, and the second RLC entity is corresponding to a second base station. By using the method and the terminal in the embodiments, frequency of RRC connection re-establishment is reduced, and a data packet loss caused by frequent re-establishment is further avoided, thereby improving user experience.

Abstract: Example implementations relate to neighboring network devices. For example, a non-transitory computer readable medium storing instructions executable by a processing resource can cause a computer to determine a characteristic affecting a subset of a plurality of network devices. The instructions can cause the processing resource to determine that at least two of the subset of the plurality of network devices that are affected by the characteristic are neighbors. The instructions can cause the processing resource to indicate a region to be associated with each network device of the subset based on the determination that at least two of the subset of the plurality of network devices are neighbors.

Abstract: A management device includes a communication controller that determines whether or not to release a communication resource reserved for a stationary terminal according to whether or not congestion is occurring in a core network at termination of communication of the stationary terminal, and a network interface unit that transmits a result of the determination by the communication controller to a base station.
