Abstract: To suppress concentration of channel quality information requests and reports in a case of discontinuously transmitting reference signals at specific resources in a time domain, and thereby preventing degradation in throughput. A transmission apparatus transmits an instruction of CSI request distributed for each reception apparatus in a subframe concurrently with or earlier than a reference signal CSI-RS to each of reception apparatuses. Each of the reception apparatuses detects the CSI request from the transmission apparatus and calculates CSI from a channel estimation value of CSI-RS received thereafter. Then, the reception apparatus identifies CSI report subframe of the own apparatus from CSI report interval information of a given time interval notified in advance, the subframe in which the CSI request is detected and transmission timing of CSI-RS, and transmits a feedback signal including CSI report value by using PUSCH at the timing of the CSI report subframe.

Abstract: Provided is a transmitter which improves the flexibility of SRS resource allocation without increasing the amount of signaling for notifying the cyclic shift amount. In the transmitter, with regard to each basic shift amount candidate group having a basic shift amount from 0 to N−1, a transmission control unit (206) specifies the actual shift amount imparted to a cyclic shift sequence used in scrambling a reference signal transmitted from each antenna port, said specification being performed based on a table in which cyclic shift amount candidates correspond to each antenna port, and based on setting information transmitted from a base station (100). With regard to basic shift amount candidates for shift amount X, the table differentiates between an offset pattern comprising offset values for cyclic shift amount candidates corresponding to each antenna port and an offset pattern corresponding to basic shift amount candidates of X+N/2.

Abstract: Provided are a radio terminal device, a radio base station device, and a channel signal forming method which can prevent quality degradation of the downlink resource allocation information by reducing the frequency of the zero information addition process to the downlink resource allocation information when executing communication using an uplink unit band and multiple downlink unit bands correlated to the uplink unit band. A base station includes: a PDCCH generation unit which includes the uplink allocation information relating to the uplink unit band only in some of the channel signals formed for each of the downlink unit bands; and a padding unit which adds zero information to the downlink allocation information only in the selected some channel signals having the bandwidth of the corresponding downlink unit band smaller than that of the uplink unit band until the downlink allocation information size becomes equal to the uplink allocation information size.

Abstract: A wireless communication base station device which makes it possible to provide a base station, terminal and CCE allocation method capable of reducing the number of times blind decoding of a terminal is performed, without increasing the CCE block rate, even when a plurality of unit bands are set in a terminal. In this device, a search space setting section (103) sets in each of a plurality of unit bands a common search space in respect of a terminal which is communicating using the plurality of unit bands and other terminals, and sets in each of the plurality of unit bands an individual search space in respect of the terminal. An allocation section (106) allocates control information solely to CCEs within the common search spaces set in specified unit bands among the plurality of unit bands, or solely to CCEs within individual search spaces set in specified unit bands.

Abstract: A base station can prevent deterioration of data channel application control accuracy due to influence of transmission power control to a control channel. In the base station, each encoding section performs encoding processing to an SCCH (Shared Control Channel) of each mobile station, each modulating section performs modulation processing to the encoded SCCH, an arranging section arranges the SCCH to each mobile station to one of a plurality of subcarriers which configure an OFDM symbol, and transmission power control section controls transmission power of the SCCH based on reception quality information reported from each mobile station. The arranging section arranges a plurality of the SCCH to be under transmission power control to one of the subcarriers so that combinations at resource blocks are the same.

Abstract: Where first and second reference signals for a first and second communication system, respectively, are transmitted, resources that affect a reception apparatus compatible only with the first communication system can be minimized, and the throughput can be prevented from being deteriorated. As resources for a reference signal CSI-RS for LTE-A, last half symbols in a time direction of a resource unit RB/Sub-frame defined in a frequency-time domain are used, and the CSI-RS is allocated in a position up to the last two symbols or in the last symbol, or the like, of a particular RB/Sub-frame and transmitted when a reference signal 4RS for LTE is transmitted to a reception apparatus in addition to transmitting CSI-RS for LTE-A. The reception apparatus receives CSI-RS allocated in the last half symbol of RB/Sub-frame based on CSI-RS allocation information, measures channel quality by using this CSI-RS, and transmits and reports feedback information.
