摘要： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when no resource allocation signal is detected in retransmission. When control information outputted from a decoding unit (204) contains NACK and retransmission Grant, a retransmission resource check unit (205) determines that the resource indicated by the retransmission Grant is the retransmission resource. Moreover, when no retransmission Grant is detected and the initial transmission is a wideband transmission, the retransmission resource check unit (205) determines that no retransmission resource exists and instructs an RB allocation unit (209) to stop retransmission. Moreover, when no retransmission Grant is detected and the initial transmission is a narrow band transmission, a predetermined resource is determined to be the retransmission resource.

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： Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).

摘要： A wireless transmission method for improving the reception characteristic of a preamble. The wireless transmission method allows the patterns of subcarriers (transmitting antenna Tx1: 1, 2, 3, 5, 6, 7, 8, . . . , transmitting antenna Tx2: 4, 9, 10, 12, 13, 14, . . . ) in which preamble sequences are continuously arranged to be changed in a frequency direction. With this, the preamble sequences can be arranged at random subcarrier intervals and, when the autocorrelation values of the preamble sequences are obtained in a time domain, the peak value of the sidelobe becomes small, thereby making it possible to prevent a timing detection error.
