摘要： A wireless communication base station apparatus wherein when a frequency scheduling transmission and a frequency diversity transmission are performed in a multicarrier communication at the same time, the adaptive control of a channel for performing the frequency scheduling transmission can be prevented from being complicated. In this apparatus, a modulating part (12) modulates an encoded Dch data to generate Dch data symbols. A modulating part (22) modulates an encoded Lch data to generate Lch data symbols. An assigning part (103) assigns the Dch and Lch data symbols to subcarriers constituting OFDM symbols and outputs them to a multiplexing part (104). At this moment, the assigning part (10) assigns a set of Dch and Lch data symbols to each subcarrier for a respective subband.

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.

摘要： Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2̂n×3̂m×5̂l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2̂n×3̂m×5̂l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number

摘要： Disclosed are a wireless transmission apparatus and transmission power control method which improve the error rate characteristics of data signals even when the number of streams of data signals increases, without increasing the amount of signaling. The relationship between the number of streams of data signals in each antenna (201-1, 201-2) and the data signal and pilot-signal transmission power ratio at each antenna (201-1,201-2) is stored. Specifically, a relationship where the data signal and pilot signal transmission power ratio at each antenna increases as the number of streams of data signals at each antenna increases is stored. A transmission power control unit (205) determines the data signal and pilot signal transmission power ratio on the basis of the information of the number of streams of data signals at each antenna (201-1, 201-2) that were output from a decoding unit (204), controls the transmission power of the pilot signals on the basis of the determined transmission power ratio, and outputs to a multiplexing unit (210).

摘要： A scheduling apparatus and a scheduling method, wherein the amount of signaling for frequency resource allocation information can be reduced while maintaining system throughput performance. In a base station apparatus (100), a scheduling section (113) allocates frequency resources to frequency allocation target terminals based on set frequency allocation units, and a frequency allocation parameter setting section (112) adjusts the set frequency allocation units set in the scheduling section (113) based on cluster numbers. Due to this, in each cluster number, frequency resources can be allocated based on the most suitable frequency allocation units with respect to the signaling bit number. As a result, the amount of signaling for frequency resource allocation information can be reduced. Further, system throughput can be maintained by making the cluster number, which is a parameter having little effect on system throughput, a setting parameter for frequency allocation units.

摘要： There is provided a multi-carrier communication method capable of preventing lowering of a throughput of another mobile device accompanying allocation of a sub-carrier for a new mobile station device. This multi-carrier communication method can acquire reception quality information for one of the sub-carriers already allocated in an MS (150a) from a BS (100a) and for one of the sub-carriers which can be allocated in the MS (150a) from the BS (100b). According to the reception quality information, a release sub-carrier is selected from the sub-carriers already allocated and a new-allocation sub-carrier is selected from the sub-carriers which can be allocated. The new-allocation sub-carrier has a frequency different from the already-allocated sub-carriers excluding the release sub-carrier. The BS (100a) is instructed to release the selected release sub-carrier and the BS (100b) is instructed to allocate the selected new-allocation sub-carrier in the MS (150a).

摘要： A wireless communication terminal apparatus and a CQI selecting method wherein when CQIs are grouped according to their levels and then an upper-order CQI, which is indicative of a group, is to be informed in a longer period, while a lower-order CQI, which identifies a CQI in the group, being to be informed in a shorter period, the CQI is precisely selected. A reception SIR range of 0-4 dB in UE corresponds to a level 1 of upper-order CQI. A next reception SIR range of 4-8 dB corresponds to a level 2 of upper-order CQI. Similarly, the following SIR ranges up to 24 dB, each of which is 4 dB higher than a respective previous one, correspond to the respective following levels of upper-order CQI. On the other hand, the levels 1-4 of lower-order CQI, with which the level 1 of upper-order CQI is associated, correspond to a SIR range of −1-5 dB. The levels 1-4 of lower-order CQI, with which the level 2 of upper-order CQI is associated, correspond to a SIR range of 2-9 dB. Thus, the SIR ranges, to which the lower-order CQIs correspond, overlap the respective SIR ranges corresponding to the respective adjacent levels of upper-order CQIs with which the lower-order CQIs are associated.
