The base station includes: a modulation unit (102) for modulating SCH data after being encoded; a sub carrier setting unit (105) for setting one of the sub carriers to a sub carrier (SCH sub carrier) constituting the OFDM symbol for SCH data transmission; and an IFFT unit (106) for mapping the SCH data to the sub carrier set by the sub carrier setting unit (105) among the sub carriers and performing IFFT to generate an OFDM symbol. The sub carrier setting unit (105) sets one of the sub carriers which has a frequency of a common multiple between the sub carrier interval and the cell search interval as an SCH sub carrier.

摘要： Provided are a base station, a terminal, a band allocation method, and a downlink data communication method in which a mapping method for synchronization signals and report signals is implemented with high resource usage efficiency when a first system in which an independent single communication is allocated to a unit band co-exists with a second system in which a plurality of unit bands can be allocated to a single communication. In a base station (200), an OFDM signal generation unit (225) maps primary synchronization channel (P-SCH), secondary synchronization channel (S-SCH), primary broadcast channel (P-BCH), and dynamic broadcast channel (D-BCH), which can be decoded by both an LTE terminal and an LTE+ terminal, to some of a plurality of unit bands available to the station itself. The OFDM signal generation unit (225) also maps D-BCH+, which can be decoded only by an LTE+ terminal, to all of the plurality of unit bands to produce a multiplexed transmission signal. When the terminal which has transmitted terminal capability information is an LTE+ terminal, a control unit (265) transmits a band movement indication which indicates changes in the reception band to that terminal.

摘要： Provided is a radio communication base station device capable of acquiring both a multi-user diversity effect and a frequency diversity effect simultaneously in multi-carrier communications. In this devices modulation units (101-1 to 101-n) modulate data to mobile stations (MS#1 to MS#n) individually to create data symbols. A separation unit (102) separates each data symbol inputted, into an Ich (in-phase components) and a Qch (orthogonal components). An Ich arrangement unit (103) and a Qch arrangement unit (104) arrange the Ich and Qch, respectively, in a plurality of sub-carriers constituting an OFDM symbols, and output the same to a synthesization unit (105). This synthesization unit (105) synthesizes the Ich and Qch arranged for each sub-carrier, to create the synthesized symbol.

摘要： The purpose of the present invention is to inhibit an increase in the amount of A/N resources, without changing the timing at which the error detection result of an SCell is notified when UL-DL configurations to be configured for each of the unit bands are different, from the timing at which the error detection result is notified when just a single unit band is configured. A control unit (208) transmits, using a first unit band, a response signal including error detection results about data received with both the first unit band and a second unit band. In a first composition pattern set for the first unit band, an uplink communication subframe is set to be the same timing as at least an uplink communication subframe of a second composition pattern set for the second unit band.
