摘要： A terminal apparatus is disclosed wherein even in a case of applying SU-MIMO and MU-MIMO at the same time, the inter-sequence interference in a plurality of pilot signals used by the same terminal can be suppressed to a low value, while the inter-sequence interference in pilot signal between terminals can be reduced. In this terminal apparatus (200): a pilot information deciding unit (204) decides, based on allocation control information, Walsh sequences of the respective ones of first and second stream groups at least one of which includes a plurality of streams; and a pilot signal generating unit (205) forms a transport signal by using the decided Walsh sequences to spread the streams included in the first and second stream groups. During this, Walsh sequences orthogonal to each other are established in the first and second stream groups, and users are allocated on a stream group-by-stream group basis.

摘要： Disclosed are a control signal transmitting method and mobile terminal device capable of switching between a plurality of terminal communication modes having different maximum transmissible power values with a high degree of precision, while suppressing increases in signaling overhead. In a mobile station (100), a PHR transmission evaluating unit (115) sends, to a base station (200), power head room (PHR) information for the SC-FDMA mode or the OFDMA mode during a reporting period, and a maximum transmission power information setting unit (101) provides notification to the base station (200) of difference information between the transmission modes prior to the beginning of the reporting period. An increase in signaling overhead can be prevented because only a single set of PHR information among the information for the plurality of terminal transmission modes is reported in this way. Providing notification of difference information between the transmission modes enables the base station (200) to calculate the PHR of each of the terminal transmission modes without receiving PHR information for all of the terminal transmission modes. This therefore enables highly accurate switching among the terminal transmission modes with appropriate timing.
摘要翻译：公开了一种控制信号发送方法和移动终端装置，其能够在抑制信令开销增加的同时，以高精度切换具有不同最大发送功率值的多个终端通信模式。在移动台（100）中，PHR发送评价部（115）在报告期间向基站（200）发送用于SC-FDMA模式或OFDMA模式的功率头室（PHR）信息，以及最大发送功率信息设置单元（101）在报告周期开始之前向基站（200）通知发送模式之间的差异信息。可以防止信令开销的增加，因为以这种方式报告用于多个终端传输模式的信息中的仅一组PHR信息。在发送模式之间提供差异信息的通知使得基站（200）能够计算每个终端传输模式的PHR，而不接收所有终端传输模式的PHR信息。因此，能够在适当的时刻使终端发送模式之间进行高精度的切换。

摘要： It is possible to provide a transmission control method, a radio communication system, and a radio base station device which can reduce the time required until an inter-cell interference is reduced so as to improve the system throughput. A base station (200) includes: an FFT unit (210) which receives an interference report transmitted by using a common radio resource common to adjacent cells from a plurality of radio terminals (100) existing in different adjacent cells; and an adaptive FFR processing unit (230) which controls adaptive FFR processing in a downstream line of the local cell according to the reception interference report. Thus, by receiving an interference report directly from the radio terminals (100) existing in adjacent cells, it is possible to modify the transmission mode by considering the interference state in the adjacent cells. This eliminates the need of sending a report on a transmission mode modification which has been conventionally sent between adjacent base stations (200). This reduces the signaling required in the system, which improves the system throughput.

摘要： A terminal and a communication method thereof whereby, even in a case of employing the asymmetric carrier aggregation system and further employing the MIMO transmission method for upstream channels, the error characteristic of control information can be prevented from being degraded. In the terminal (200), a transport signal forming unit (212) forms transport signals by arranging, based on a arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer that is different from a layer in which the channel quality information is arranged. In this way, the puncturing of CQI using ACK/NACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded.
