摘要： The present invention relates to methods and arrangements that enable easy integration of on/off repeaters in a radio access network and a minimized signaling for the UE repeater selection. This is achieved by a solution where the RBSs are working in a pre-coding mode and where the repeaters are measuring the downlink reference signals, selecting pre-coding matrices and feeding the index of selection back (i.e. the PMI) to the RBS, in analogy with what a UE does. This allows the RBS to distinguish the UE repeater selection, without introducing any extra uplink report or interaction between UEs and repeaters, by comparing the index from the UE with the indices from different repeaters.

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.

摘要： The present invention relates to a method and arrangements in a communication system for Multi User Multiple-Input-Multiple-Output (MU-MIMO) signaling via Multiple-Input-Multiple-Output (MIMO) antennas between a base station and one of a plurality of mobile terminals supporting both Single User and Multi User Multiple-Input-Multiple-Output (SU-MIMO and MU-MIMO) signaling modes. Switching between the modes is supported in the system and the modes have partly shared signaling. SU-MIMO mode signaling which is redundant, i.e. not needed, for MU-MIMO mode signaling is identified. Bits, i.e. data bits, of the identified redundant signaling is re-interpreted or re-defined to comprise signaling information associated with MU-MIMO mode. The signaling information associated with MU-MIMO mode is signaled to the mobile terminal by using the reinterpreted redundant bits.

摘要： A method in a terminal for providing an ACK/NAK message to a base station is provided. The terminal counts the number of assigned downlink subframes detected from the base station resulting in k. The terminal then establishes whether each of a number of transport blocks comprised in the counted k downlink subframes is correctly received or not. In the case when each one of the transport blocks, comprised in the k downlink subframes is estimated as correctly received the terminal provides to the base station an encoded ACK message for the k subframes, which comprises k, the number of subframes.
