摘要： In a method for power control in a telecommunication system, the transmit power is adjusted based on at least the mutual information expression or a representation thereof. According to one aspect the transmit power for a coming slot is controlled based on the previously received slots, wherein an estimated quality is compared to a determined quality target based on the mutual information expression.

摘要： The present invention relates to a method and apparatus for selecting radio resources for transmission of data over a radio link to which at least two resource units have been allocated. At least one resource unit is selected out of the allocated resource units, wherein the selection is determined in dependence of the result of checking whether values of a quality measure of the allocated resource units fall within a certain range.

摘要： A method of adapting resource allocation parameters to reach one or more quality targets with improved accuracy is proposed. New information measurements based on the so-called mutual information, preferably at block-level, are introduced. The MI-based information measurements of a previous transmission, the channel prediction of a subsequent transmission and one or more quality requirements, are used to determine the amount and type of resources, e.g. time, frequency and power resources, that are to be used for the subsequent transmission. The resource allocation can for example comprise power allocation and/or link adaptation and the invention enables an advantageous implementation with cooperative link-adaptation and power allocation. The proposed method is useful in connection with ARQ/HARQ retransmissions.

摘要： Provided is a leak-proof lubrication system for a power device, comprising an oil supply pump inlet pipe, an oil supply pump, an oil supply pressure gauge, an oil supply pump outlet pipe, an oil supply filter, a lubricating oil, an oil storage tank, an oil return pipe, an storage tank pressure gauge, a vacuum pump intake pipe, a vacuum pump inlet air filter, a vacuum pump and a vacuum pump exhaust pipe. The system employs a negative pressure operation method in which the pressure of the lubrication system is controlled to be lower than the outside ambient pressure, which allows a small amount of air to flow from the outside to the inside of the lubrication system along with the lubricant to return to the storage tank, preventing leakage of the lubricant from connection joints. It is suitable to be used for gas turbines or other high-speed power machines.
