    • A wireless transmission apparatus able to reliably increase outage capacity according to the state of a propagation path. This apparatus is a wireless transmission apparatus (100) which transmits a plurality of streams to a wireless reception apparatus; wherein a time/space allocation determining unit (107) determines the spatial multiplex stream number based on the desired multipath number and the number of reception antenna ports of the wireless reception apparatus, said desired multipath number being calculated based on the detected multipath number, the number of reception antenna ports, and the desired error rate for the plurality of streams; a stream dividing unit (109) divides the transmission data into a plurality of streams of that spatial multiplex stream number; a transmission weight calculation unit (108) calculates a transmission weight based on the desired multipath number, spatial multiplex stream number, and a channel estimation value; and a time precoding unit (1103) and a spatial precoding unit (111) use the transmission weight to precode the plurality of streams.

    • There is provided a punching unit that is readily adjusted, is capable of always punching high quality holes through sheets and is steadily capable of discharging punch chips. A punch shaft and a die shaft are disposed vertically in parallel between side plates and these very punch shaft and the die shaft compose structural members (reinforcing members) of the punching unit. The die shaft has a die shaft body formed into a hollow cylinder and is provided with dies that correspond to the punches of the punch shaft at an outer peripheral surface thereof while fitting into die holes penetrating to the hollow section. A chip discharging screw plate fixed to the right side plate is disposed in the hollow section of the die shaft. Punch chips are transported along slopes of the chip discharging screw plate and discharged out of an opening when the die shaft rotates.

    • There are provided a communication device, a base station, a communication system, and a communication method that make it possible to yield a diversity effect by cooperative relay without involvement of disproportionateness in data received by an eNB even when one of parties has unsuccessfully exchanged data. After received an ACK signal from a repeater 1, a repeater 2 which has transmitted a NACK signal in procedure 7 transmits data S2 to the eNB by use of its own resource, thereby making its own resource available for the repeater 1 (the repeater 2 does not use its own resource, and the repeater 1 uses the resource of the repeater 2). In procedures 8, the repeater 1 has received the NACK signal from the repeater 2 and subsequently transmits data S1 to the eNB by use of its own resource. Subsequently, the repeater 1 which has received the MACK signal in procedure 9 determines that the resource of the repeater 2 is available and transmits data P1 to the eNB by use of the resource of the repeater 2. In procedure 10, the repeater 1 transmits previously-generated data P2 to the eNB by use of its own resource.
    • 提供了一种通信设备,基站,通信系统和通信方法,其可以通过协同中继产生分集效应,而不涉及由eNB接收的数据中的不成比例,即使当一方有成功交换的数据 。 在从中继器1接收到ACK信号之后,在过程7中发送了NACK信号的中继器2通过使用其自己的资源向eNB发送数据S2,从而使其自己的资源可用于中继器1(中继器2 不使用自己的资源,中继器1使用中继器的资源2)。 在过程8中,中继器1已经从中继器2接收到NACK信号,并且随后利用自己的资源向eNB发送数据S1。 随后,在过程9中接收到MACK信号的中继器1确定中继器2的资源可用,并且通过使用中继器2的资源将数据P1发送到eNB。在过程10中,中继器1先前 生成的数据P2通过使用其自己的资源到eNB。
