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 are a radio transmission device and a radio transmission method which can suppress lowering of the throughput caused by switching between the single carrier communication method and the multi-carrier communication method while suppressing increase of the signaling amount. A PHR threshold value setting unit (116) sets a threshold value Y1 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 judgment unit (117) 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 Y1.

摘要： Disclosed is a wireless communication base station apparatus capable of preventing degradation of throughput of LTE terminals, even when both LTE terminals and LTE+ terminals are present together. In this apparatus, a CCE allocation section (105) allocates the characteristic cell reference signals, which are employed solely by LTE+ terminals, to some CCEs from a plurality of CCEs to which a control channel for LTE terminal use or a control channel for LTE+ terminal use can be allocated. In the case of symbols that are mapped to antennas (113-5) to (113-8), an arrangement section (109) arranges the characteristic cell reference signals that are employed solely by LTE+ terminals in resource elements corresponding to CCEs to which a characteristic cell RS has been allocated that is used solely by an LTE+ terminal, based on position information that is input from an interleaving section (106). Wireless transmission sections (112-1) to (112-8) transmit these symbols, that have been thus input, to each terminal from the antennas (113-5) to (113-8).
