Abstract: In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands.

Abstract: In a method and apparatus for scheduling users in radio network system, the scheduling priority for each user of a group of users is made dependent on the unusable time for each user. Scheduling of the users is performed in accordance with the determined scheduling priority.

Abstract: A method of supporting frequency-selective repeaters (eNodeRs) in a wireless telecommunication system. A base station (eNodeB) classifies User Equipments (UEs) into two categories or lists of users: a white list containing UEs that may need the assistance of repeaters, and a black list containing UEs that do not need repeater assistance. The eNodeB transmits one of these two lists to the eNodeRs. The eNodeRs do not amplify resource blocks (RBs) scheduled for black list UEs. Each repeater may decide on its own whether to amplify signals for a non-black list UE by measuring signals from the UE and comparing them with predefined criteria.

Abstract: A semiconductor wafer contains a substrate having a plurality of active devices formed thereon. An analog circuit is formed on the substrate. The analog circuit can be an inductor, metal-insulator-metal capacitor, or resistor. The inductor is made with copper. A through substrate via (TSV) is formed in the substrate. A conductive material is deposited in the TSV in electrical contact with the analog circuit. An under bump metallization layer is formed on a backside of the substrate in electrical contact with the TSV. A solder material is deposited on the UBM layer. The solder material is reflowed to form a solder bump. A wire bond is formed on a top surface of the substrate. A redistribution layer is formed between the TSV and UBM. The analog circuit electrically connects through the TSV to the solder bump on the back side of the substrate.

Abstract: Techniques are provided to obviate unnecessarily requesting that different types of measurements are simultaneously made by a user equipment unit (30) in anticipation of a handover in a radio access network. In accordance with one aspect of the technology, in preparing a measurement request for a user equipment unit (served by a currently utilized cell) to measure on signal(s) transmitted from other cell(s) for evaluating handover potential; a network node uses at least one deployment parameter for selecting between three measurement alternatives for the measurement request. In a generic embodiment, the three measurement alternatives are: (1) performing only a first type of measurement(s); (2) performing only a second type of measurement(s): and (3) simultaneously performing both the first type and the second type of measurement(s).

The method includes recognizing multiple-person interaction primitives, composing an event by inference based on temporal relations using the multiple-person interaction primitive, and determining a final event by either eliminating an unnecessary event from the composed event, or adding a new event in the composed event.

Abstract: The invention relates to the control and adaptation of transmit parameters for wireless communication between a transmitter (TX) and at least one receiver (RX) to provide joint power and link adaptation. A basic idea of the invention is to collectively determine the transmit duration (T) and transmit power (P) of the transmitter based on minimization of a given objective function representative of total consumed energy, on both the transmitting side and the receiving side, with respect to transmit duration and/or transmit power. In effect, this means that link transmit parameters are determined based on the energy consumption on both the transmitting side and the receiving side. In addition, both transmit power and transmit duration are varied, while minimizing overall consumed energy.

Abstract: By introducing a novel parameter common to all links along the entire multihop route it is possible to more flexibly allocate, for each of a number of the links, a set of three interdependent link transmit parameters representative of link transmit energy, link transmit time or link transmit bandwidth or link code word consumption, and link transmit power. Basically, the common parameter is determined based on a given end-to-end (ETE) transmit parameter constraint for the entire multihop route. The idea is then to assign or allocate, for each considered link, the three interdependent link transmit parameters based on the common parameter and local link characteristics. In this way, all three link transmit parameters may (and generally will) be different between at least two links on the route when the links have different link characteristics, assuming that each link transmit parameter is also dependent on the local link characteristics.

Abstract: The inventors have envisioned a multihop network scenario in which nodes are equipped with advanced multi-antenna arrangements, and recognized the advantage of exploring the presence of such advanced antenna arrangements in multihop network nodes for the specific purpose of determining link cost for routing in the network. A basic idea of the invention is therefore to determine link cost for a wireless link between a pair of nodes in the network based on multi-channel characteristics between the nodes, where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels. These multi-channel characteristics may for example be determined based on explicit channel matrix estimation and/or the number of transmit and receive antennas or other information on the antenna capabilities of the involved nodes. The determined link cost information may subsequently be used together with additional routing cost information for route determination, and packet forwarding.

Abstract: An inrush current controller for a device has a connector for hot-plugging the device into a source of energization. An impedance has a current input coupled to a first contact of the connector and a current output coupled to the device. The impedance has an impedance control input. An impedance control circuit has a logic input coupling to a second contact of the connector. The impedance control circuit has an impedance control output connected to the impedance control input. The impedance control output forces the impedance OFF during a first time interval after hot-plugging. The logic input triggers a limited inrush at the current input after the first time interval.

Abstract: In a method for relaying deployment in a wireless communication system comprising a transmitting node with multiple antennas for communicating with at least one receiving node via at least two relay nodes, a data stream at the transmitting node is partitioned into at least two data substreams, each of which is beamformed and transmitted over a first link to a respective of the relay nodes; subsequently at least one restorable representation of each received substream is forwarded over a second link to the receiving node from the two relay nodes; and finally the received and decoded representations are multiplexed to form an output signal at the receiving node corresponding to the original data stream.
