摘要： The present solution provides a method in a base station (110) for selecting one or more user equipments (120) to be scheduled for a transmission. After receiving (201) channel state information from the respective one or more user equipments (120), the base station (110) estimates (202) the throughput of the transmission of the respective one or more user equipments (120). The throughput is based on the received channel state information. The base station (110) further estimates (203) the consumption of throughput that is expected for transmitting scheduling information to each of the respective one or more user equipments (120). The base station then selects (204) the respective one or more user equipments (120) to be scheduled for transmission based on a criterion. The criterion is based on the estimated throughput and the estimated consumption of throughput that is expected for transmitting the scheduling information to the respective one or more user equipments (120).

摘要： Methods and nodes in a communication system for conveying N additional bits with a block of data. A method in an encoding node involves determining the respective value of the N additional bits, and selecting a code based on the N values. The block of data is then encoded by use of the selected code. A method in a decoding node involves determining which code, from a predetermined set of candidate codes associated with different possible combinations of values of the N additional bits, that was used for encoding the block of data. The respective values of the N additional bits are then determined based on the determined code. The methods and nodes enable that the N additional bits may be conveyed and determined in the decoding node in an efficient way, without decoding the block of data and at low computational complexity.

摘要： According to the teachings presented herein, a method and apparatus for communication signal processing advantageously use a mix of parametric and non-parametric correlation estimation in communication signal processing. Non-parametric estimation generates an “overall” correlation estimate for a received communication signal, and parametric estimation generates a “component” correlation estimate. The component correlation estimate is removed from the overall correlation estimate to form a partial correlation estimate that is used to process the received communication signal at least initially, such as in a pre-equalization stage. The overall and component correlation estimates are generated as impairment and/or data correlation estimates.

摘要： In selecting location measurement units for measuring an uplink signal received from a mobile communication station operating in a wireless communication network in order to locate the position of the mobile communication station in the wireless communication network, a possible position of the mobile station in the network is identified. The location measurement units to be used in measuring the uplink signal can then be identified by evaluating one or more of relative positional relationships between the possible position of the mobile station and a plurality of further positions respectively associated with a plurality of location measurement units in the network; path loss measures predicted for each of a plurality of location measurement units relative to the possible position of the mobile station; and geometric dilution of precision (GDOP) values determined for each of a plurality of groups of location measurement units with respect to the possible position of the mobile station.

摘要： A helical gear pump in which the rotor is made of a wire or bar wound into a cylindrical helix. The rotor is made by twisting two wires or bars around each other, separating the two helices so formed, and using one or both of them as a rotor. The stator is made of a tube of plastics which is formed by inserting into the tube a mandrel having threads correspondng to required internal threads of the stator, causing the plastics tube to soften and applying external pressure to it to make its inside assume a shape corresponding to that of the mandrel. The mandrel is made by winding helically two wires about a third straight wire and securing the first-mentioned two wires to the third wire, all the said wires having about the same diameter as the wire of which the rotor is made.
