  • Publication number: 20150349938
    Abstract: Transceiver node and method therein for enabling dynamic bandwidth assignment in bi-directional Time Division Duplexing (TDD) multicarrier communication over wire lines. The transceiver node is operable to be coupled to a plurality of loops, wherein each loop is terminated by a respective network terminal (NT). The method comprises collecting traffic reports from local and remote queues associated with uplink and downlink traffic on the plurality of loops, and determining an actual demand for upstream and downstream bandwidth, respectively, for each of the plurality of loops, based on the collected traffic reports. The method further comprises deriving an Upstream/Downstream (US/DS) frame partitioning based on the determined actual demand for upstream and downstream bandwidth, and providing an indication of the derived US/DS frame partitioning to the NTs. NTs are then scheduled in accordance with the derived partitioning.

  • Publication number: 20150223199
    Abstract: The present disclosure relates to a method performed in a network node in a communication network. The method comprises receiving instructions to monitor whether a first service is sending a message intended for a radio device. The method also comprises monitoring the first service, in accordance with the received instructions, in order to obtain information relating to whether the service is sending a message intended for the radio device. The method also comprises processing the obtained information such that a decision can be made whether to wake up the radio device. The present disclosure also relates to a network node and to a radio device.

  • Publication number: 20150172988
    Abstract: A node and method for communication with a user equipment, UE, are provided. The source node includes at least one processor configured to cause transmission of a first handover command message to the UE. The first handover command message includes first configuration information for handover to a target node. At least one receiver is configured to receive second configuration information from the target node after transmission of the first handover command message to the UE. The at least one processor is further configured to cause transmission of a second handover command message to the UE. The second handover command message includes the second configuration information received from the target node. The first configuration information is configured to be used in combination with the second configuration information to allow the UE to access the target node for handover.

  • Patent number: 9048978
    Abstract: The invention relates to a method and a system for generating clock signals in a wireless communication device. The method includes generating an uncorrected reference clock signal, generating at least one frequency correction value corresponding to a frequency error in the uncorrected reference clock signal, and generating at least one radio frequency clock signal based on the uncorrected clock signal and the at least one frequency correction value, for receiving and transmitting radio frequency signals. The method further comprise generating, independently of the at least one radio frequency clock signal, a baseband timing signal based on the uncorrected reference clock signal and the at least one frequency correction value, for clocking base-band signal processing circuits.

  • Patent number: 9049035
    Abstract: The invention is embodied in a technique for broadcasting content data from a broadcaster (including a multicaster) to a plurality of clients. After a client receives content data from the broadcaster, a plurality of available proxy servers may be contacted for post-processing after the content data broadcast is determined. The client subsequently randomly selects one of the available proxy servers to contact for post-processing after the content data broadcast. The client may further randomly select a delay time within a contact interval for the selected proxy server, at which time the client contacts the selected proxy server at the delay time to initiate post-processing.

  • Publication number: 20150087346
    Abstract: A first User Equipment (UE), a second UE, a first Radio Network Node (RNN), and methods therein for controlling interference between transmissions in a first system and transmissions in a second system. The first system comprises the first UE and the first RNN serving the first UE. The second system comprises the second UE and a second RNN serving the second UE. The first system has a first priority in a first part of a shared spectrum and the second system has a second priority in the first part of the shared spectrum, wherein the first priority is higher than the second priority. The method in the first UE comprises transmitting a signal to a second RNN that is to perform a downlink transmission to the second UE, which signal is configured to control the transmission of the second RNN.

  • Publication number: 20150009927
    Abstract: A method in a user equipment (121) for determining a transport block size is provided. The transport block size is used by the user equipment (121) in receiving downlink data transmissions from a network node (110) on an enhanced Control CHannel, eCCH. The user equipment (121) and the network node (110) are comprised in a telecommunications system (100). The user equipment (121) has access to a table of predetermined transport block sizes. The user equipment (121) may calculate an indicator NPRB based on the total number of PRBs allocated to the downlink data transmission NPRB, and based on an PRB offset value OPRB or a PRB adjustment factor APRB. Then, the user equipment (121) may determine the transport block size from the table of predetermined transport block sizes based on at least the calculated indicator NPRB. A user equipment, a method in network node and a network node are also provided.

  • Publication number: 20140347248
    Abstract: A node in a wireless communication network, the node comprising at least two antenna columns which are physically separated from each other, each antenna column comprising at least one dual polarized antenna element. Each antenna element has a first polarization and a second polarization. The node further comprises at least two four-port power dividers/combiners, each power divider/combiner having a first port pair and a second port pair, where, for each power divider/combiner, power input into any port in a port pair is isolated from the other port in said port pair, but divided between the ports in the other port pair. Antenna ports of antenna columns that are pair-wise physically separated, from those pairs of antenna columns that are most physically separated to those that are least physically separated, are cross-wise connected to the first port pair in corresponding power dividers/combiners.

  • Patent number: 6930873
    Abstract: Characteristics of micro electromechanical switches can be changed by applying a control signal which either changes one or more parameters of the micro electromechanical switches or which controls beam movement by feedback signals. It is thereby possible to change switching transient time, maximum switching frequency, power tolerance, and/or sensitivity (actuation voltage) of a micro electromechanical switch.
