摘要： Provided are a radio transmission apparatus and a radio transmission method whereby the increase of number of signaling bits can be suppressed and further the flexibility of frequency scheduling can be improved. A notified RBG calculating unit (203) that adds a predetermined offset value of “1” or “−1” to one of the start RBG number and the end RBG number of allocated RBG number information (b′i) output by a scheduling unit (201), thereby calculating notified RBG number information (bi). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding “1” to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (bi) and the notified total number of RBGs (Nrb′) to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).

摘要： Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

摘要： It is possible to provide a radio transmission device and a radio transmission method which can avoid degradation of a channel estimation accuracy using a reference signal formed by a ZC sequence even when the RS transmission band of a local cell is different from that of an adjacent cell. A mobile station decides a cyclic shift sequence corresponding to RB allocation information from an RS table which correlates different frequency bandwidths from a reference point of respective transmission bands to a spectrum start number of the cyclic shift sequence so as to satisfy a particular relationship based on the sequence length and transmits the decided cyclic shift sequence as RS to a base station. The base station uses the same RS table as the RS table of the mobile station and performs correlation calculation of the RS transmitted from the mobile station, thereby performing channel estimation.

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： A radio transmission apparatus and a radio transmission method suppress lowering of the throughput caused by switching between the single carrier communication method and the multi-carrier communication method while suppressing increase in the signaling amount. A PHR threshold value setter sets a threshold value at a position greater by a predetermined value than the PHR at which the throughput performance of the SC-FDMA coincides with that of the OFDMA. A trigger signal transmission judger judges that a mobile station transmits a trigger signal for switching from the OFDMA to the SC-FDMA if the PHR in the OFDMA communication method is lower than the threshold value.

摘要： Provided are a wireless transmission device, a wireless reception device, and a bandwidth allocation method for, when non-contiguous bands allocation is performed, improving the frequency resource use efficiency of a system and thereby improving the system performance.

摘要： Disclosed is a base station capable of minimizing in Type 0 assignment the number of resource block groups occupied by a terminal that performs frequency hopping, and thereby flexibly assigning resources in the Type 0 assignment. The base station (100) is used in a radio communication system in which a plurality of resource blocks constituting the system band thereof are grouped into resource block groups each consisting of P resource blocks, and the band that is not a PUCCH-assignable band to which PUCCHs assigned to both ends of the system band can be assigned is divided into a plurality of sub-bands. The base station (100) comprises an assignment unit (1102) and a demapping unit (112). The assignment unit (1102) assigns a plurality of resource blocks in units of resource block groups to terminal apparatuses to be subjected to noncontiguous-band assignment. The demapping unit (112) extracts, from a plurality of resource blocks in a second band, data signals for which frequencies are hopped by a frequency-hopping terminal apparatus from one to another of the plurality of sub-bands. Here, the bandwidth of each of the plurality of sub-bands is a natural-number multiple of P.
