摘要： With respect to a wireless communication system comprising a transmitter device 200, which is equipped with a function for performing inflated lattice precoding (ILP) on transmission data, and a receiver device 300, which receives a signal transmitted from the transmitter device and restores data, there is adopted a feature wherein “coefficient α” which is required when the transmitter device 200 performs the above-mentioned ILP, and which is also required when the receiver device performs data restoration, is uniquely derived using information relating to an MCS (modulation parameter) that is applied with respect to the wireless communication system (more specifically, a feature wherein a “coefficient table part,” which uniquely maps MCS information to coefficient α, is provided at both the transmitter device and the receiver device, and wherein coefficient α required at both the transmitter device and the receiver device is derived using this “coefficient table part”), thereby evading having to exchange information relating to “coefficient α” between the transmitter device and the receiver device.

摘要： There is provided a first base station device in a communication system in which, within a wide coverage area of a first cell, at least one second cell having a coverage area narrower than the coverage area of the first cell is present, the first base station device controlling the first cell. The first base station device supplies information concerning a transmission weight to a second base station device which controls the second cell, the transmission weight being used by a terminal device which transmits a data signal to the second base station device. With this configuration, in a system in which a plurality of cells with a small zone radius are present in a cell with a large zone radius, it is possible to determine, with a small amount of calculations, transmission and reception weights that can eliminate interference received by the cell with a large zone radius from the plurality of cells with a small zone radius.

摘要： A wireless communication system includes a plurality of transmission devices, each of which transmits signals resulting from precoding performed for a plurality of resources, and a reception device that receives at least one desired signal and a plurality of undesired signals, the number of which is greater than or equal to the degree of freedom that the plurality of resources have. The at least one desired signal and the plurality of undesired signals have been transmitted from the transmission devices. The plurality of resources is the unit of precoding. At least one of the plurality of transmission devices transmits signals on each of which precoding has been performed such that equivalent channel vectors of the plurality of undesired signals in the reception device are made to be orthogonal to a reception weight vector used in the reception device. The reception device estimates equivalent channel vectors of the plurality of undesired signals, calculates a reception weight vector by using the estimated equivalent channel vectors of the plurality of undesired signals, and extracts a desired signal by multiplying a reception signal received using the plurality of resources and the calculated reception weight vector together. The plurality of resources is the unit of precoding. As a result, in a system in which IA is used, the degradation of reception characteristics may be suppressed even under circumstances in which a CSI error occurs.

摘要： To provide a remote controller into which a kitchen timer function and a television control function are integrated so that mutual cooperation between cooking and television watching is simplified. As shown in FIG. 5, when executing a kitchen timer function using a remote controller 50, a user depresses a function selection button 71 predetermined number of times to select the kitchen timer function. Next, the user depresses a first time period setting button 72 to set a “minute” unit portion of the desirable time period and then depresses a second time period setting button 73 to set a “second” unit portion of the time period. Finally, the user depresses a SET/STOP button 74 and the kitchen timer function starts. When the timer counts down and its display indicates “0 minute and 0 second”, a buzzer 58 of a remote control section 56 gives an alarm sound. Further, the remote control section 56 switches the display of a liquid crystal display section 54 to a clock time display.

The communication system determines the number of streams to be transmitted by the second base station apparatus on the basis of information regarding the number of streams to be transmitted by the first base station apparatus. As a result, in a system in which interference between cells exists, interference may be reduced with a simple structure using transmit and receive filters.
