摘要： In a case where a second reference signal for a second communication system is transmitted in addition to a first reference signal for a first communication system, 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, DVRB resources in which a resource unit defined in a frequency-time domain is divided in a time direction and distributedly allocated at predetermined frequency intervals are used and CSI-RS is allocated in a resource ID of a part of DVRB resources 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 DVRM resources on the basis of DVRB setting information for CSI-RS, measures channel quality such as CQI, PMI or RI by using CSI-RS, and transmits and reports feedback information containing channel quality information to a transmission apparatus.

摘要： The present invention makes it possible to obtain the transmission diversity effect by applying a CDD while reducing the inter-code interference when performing a code multiplexing. When an Ack/Nack signal is transmitted from a user terminal to a base station in an upstream control channel by using an Ack/Nack resource, the signal is code-multiplexed by using a code sequence containing an orthogonal sequence and a cyclic-shifted sequence and transmitted from a plurality of user terminals to the base station. Upon using an aggregation size indicating the number of control signals of the downstream control channel, if the aggregation size is greater than one, it is determined that no resource located at the right of the axis of the cyclic-shifted amount of the cyclic-shifted sequence in the same orthogonal code of the orthogonal sequence is used, and the Ack/Nack signal to which CDD is applied from a plurality of antennas is transmitted by using a resource ACK #0 allocated to the own device and an unused resource ACK #1, which have the same orthogonal code, but have different cyclic-shifted amounts.

摘要： Disclosed is a wireless communication base station apparatus whereby it is possible to prevent degradation of throughput of LTE terminals, even when LTE terminals and LTE+ terminals are present together. In this apparatus, a setting section (105) sets in each subframe a resource block in which is arranged a reference signal that is employed solely by LTE+ terminals, based on the pattern of arrangement of reference signals employed solely by LTE+ terminals. In the case of symbols that are mapped to antennas (110-1) to (110-4), an arrangement section (106) arranges the characteristic cell reference signals employed by both LTE terminals and LTE+ terminals in all of the resource blocks in a single frame. In contrast, in the case of the symbols that are mapped to the antennas (110-5) to (110-8), the arrangement section (106) arranges in some of the resource blocks, that are set in accordance with the setting results input from a setting section (105), the characteristic cell reference signals that are employed solely by the LTE+ terminals.

摘要： It is possible to provide a radio resource management device, a radio communication base station device, and a radio resource management method which can reduce a reply signal inter-cell interference and suppress decrease of the number of ACK/NACK which can be transmitted. When a plurality of CCE are allocated for PDCCH transmission, among usable CCE, the CCE number used between adjacent cells is differentiated. More specifically, a different RN satisfying RN=(usable CCE number m) mod N is allocated to the adjacent cell. A mobile station performs ACK/NACK transmission by using a PUCCH resource corresponding to the CCE number which becomes the allocated RN.

摘要： Provided is a radio communication base station device capable of suppressing degradation of a signal error ratio characteristic for a mobile station in the vicinity of the cell center when a plurality of signals whose transmission power is to be controlled are frequency-multiplexed or code-multiplexed. In the device (100), a classification unit (118) classifies a plurality of DPCCH according to the MCS of SCCH into a plurality of groups based on the transmission power intensity. A spread code is allocated for each DPCCH according to the classification result. A spread code for spreading a response signal (ACK signal/NACK signal) is instructed to spread units (103-1 to 103-n). The spread units (103-1 to 103-n) spread the response signal by the spread code instructed from the classification unit (118). According to the classification result in the classification unit (118), a mapping unit (104) maps the response signal after the spread to one of the subcarriers constituting the OFDM symbol.
