    摘要： A transmission/reception apparatus and method for reducing the amount of feedback information transmitted from a receiver in a multi-user MIMO system are provided. A transmitter determines a reference Channel Quality Information (CQI) and transmits the reference CQI to the receiver. Upon receipt of the reference CQI, the receiver compares the received reference CQI with a CQI of a stream received from the transmitter, sets a channel, over which the stream is received, to at least one of Activation and Inactivation, according to the comparison result, and transmits the set channel information to the transmitter. As a result, the receiver, even though it receives multiple streams from the transmitter, transmits to the transmitter the at least one of Activation and Inactivation information of the channel separately for each individual stream, thereby contributing to a reduction in the total amount of feedback information.

    摘要： A labeling and preparation device for test tubes. At least one storage section places at least one pallet having a set of test tubes at a preset position. At least one transfer section is disposed above the storage section, and clamps or releases one of the test tubes. A labeling section is disposed below the transfer section, receives the test tubes transferred from the transfer section, and attaches a label having information related to a sample on a circumference of each test tube. An ejection section is disposed below the labeling section, and ejects the test tubes to an outside. A controller controls drivers of the transfer section, the labeling section and the ejection section.
