摘要： Disclosed is a base station which can prevent degradation in the reception characteristics of nearby cells when carrier aggregation and channel selection are applied. In accordance with the resistance to interference of a plurality of uplink component carriers of a femtocell, a response protocol controller (101) in a base station (100) changes combination rules for the uplink component carriers and signal points which a terminal (200) in a microcell covered by the base station (100) uses in the feedback of a response signal. Information in relation to the combination rules is notified to the terminal (200). A controller (217) in the terminal (200) changes the combination rules for the uplink component carriers and the signal points of the microcell covered by the base station (100) in accordance with the information notified from the base station (100), and controls transmission of the response signal in accordance with said rules.

摘要： In ARQ where a plurality of mobile stations share and use a single channel for response signals (ACK/NACK signals), a wireless communication base station apparatus can prevent failure of the ARQ control. In this apparatus, a CRC part (114) performs an error detection using CRC for an uplink data, and generates, as a response signal, an ACK signal in a case of CRC=OK or a NACK signal in a case of CRC=NG. A retransmittal determining part (115) determines whether the response signal is for an initially transmitted data or for a retransmitted data. A constellation control part (116) controls, in accordance with a determination result of the retransmittal determining part (115), a constellation pattern to be used in a modulation in a modulating part (105). The modulating part (105) modulates the response signal for the retransmitted data in accordance with the constellation pattern controlled by the constellation control part (116), that is, a constellation pattern obtained by reversing the constellation pattern of the response signal for the initially transmitted data.

摘要： Provided is a wireless communication apparatus by which reduction of a diversity gain can be suppressed at minimum in the case of employing a repetition technology in multicarrier communication. In the wireless communication apparatus (100), repetition sections (102-1 to 102-n) repeat each data symbol inputted from modulating sections (101-1 to 101-n) to create a plurality of identical data symbols. An allocating section (103) outputs each data symbol to a multiplexing section (105) by allocating the data symbol to a plurality of subcarriers constituting an OFDM symbol. At this time, the allocating section (103) allocates at least one of the repeated identical symbols to a subcarrier different from a subcarrier to which the symbol is allocated in an adjacent sector.

摘要： Provided is a wireless communication base station device that can avert PHICH collisions between mobile stations when using a frequency hopping retransmission method in combination with a PHICH grouping method. A base station (100) is used in a wireless transmission system in which uplink data is allocated to multiple resource blocks, each M consecutive resource blocks form a block (M being an integer greater than 1), and each N consecutive resource blocks form a group (N being an integral multiple of M). A demultiplexer (115) follows a hopping pattern which changes the frequency for each block of multiple resource blocks, and extracts from the resource blocks uplink data for each of multiple mobile stations. Also, a mapping unit (103) maps PHICHs, to which response signals for uplink data for each mobile station are allocated, to downlink resources in accordance with associations between groups and PHICHs.
