Abstract: 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.

The wireless communication system further comprises the user equipment. The first base station estimates (403) a first offset value for a first set of subframes based on a first channel information. The first base station further estimates (404) a second offset value for a second set of subframes based on a second channel information. The first base station transmits (405) the estimated first offset value and the estimated second offset value to the user equipment. The first base station then obtains (407) channel state information from the user equipment.
