摘要： A method, transmitter node, and receiver node for communicating a transport block of information bits from the transmitter node to the receiver node. The transmitter node encodes the information bits and divides the coded bits into antenna selection bits and modulation bits. The antenna selection bits are used to select a transmit antenna from a plurality of transmit antennas. The modulation bits are used by a modulator to select modulation symbols for transmission utilizing the selected antenna. The receiver node receives the radio signal with a front-end receiver and computes a plurality of combined signals, each corresponding to one hypothesized transmit antenna at the transmitter node. The receiver forwards the plurality of combined signals to a soft value computer, which computes soft values for the antenna selection and modulation bits. The soft values are combined and decoded to produce decision bits for recovering the transport block.

摘要： An object of the present invention is to provide a mechanism for improving the detection of missed DL assignment. A method in a base station (110) for sending a data packet to a mobile terminal (120) is provided. The base station (110) uses a current bundling window for transmitting data packets in subframes of a radio channel. The bundling window comprises a number of data packets, already transmitted or to be transmitted to the mobile terminal (120). The data packets are to be confirmed by the mobile terminal (120). In a first subframe, the base station signals to the mobile terminal (120), a first downlink assignment of a first data packet of the bundling window. The downlink assignment comprises knowledge about a minimum total number of data packets within the bundling window that are scheduled to be transmitted to the mobile terminal (120).

摘要： The present invention is a high efficiency permanent magnet machine capable of maintaining high power density. The machine is operable over a wide range of power output. The improved efficiency is due in part to copper wires with a current density lower than traditional designs and larger permanent magnets coupled with a large air gap. In a certain embodiment wide stator teeth are used to provide additional improved efficiency through significantly reducing magnetic saturation resulting in lower current. The machine also has a much smaller torque angle than that in traditional design at rated load and thus has a higher overload handling capability and improved efficiency. In addition, when the machine is used as a motor, an adaptive phase lag compensation scheme helps the sensorless field oriented control (FOC) scheme to perform more accurately.
摘要翻译：本发明是能够保持高功率密度的高效率永磁电机。该机器可在广泛的功率输出范围内工作。提高的效率部分是由于电流密度低于传统设计的铜线，并且具有大的气隙耦合的较大的永磁体。在某些实施例中，通过显着地减小导致较低电流的磁饱和度，使用宽的定子齿来提供额外的改进的效率。该机器在额定负载下也具有比传统设计小得多的扭矩角，因此具有更高的过载处理能力和更高的效率。此外，当机器用作电动机时，自适应相位滞后补偿方案有助于无传感器场定向控制（FOC）方案更准确地执行。
