摘要： To improve the operation and the effect of ICIC by appropriately limiting resources of a reference signal. An SRS generating unit (154) generates an SRS as a reference signal based on SRS information transmitted from a reception unit (156), and a transmission unit (155) transmits the SRS based on the SRS information transmitted from the reception unit (156). At this time, by using information that represents an SRS drop resource as a transmission drop resource set in advance, the transmission of the SRS from the transmission unit (155) is dropped in a resource in which an SRS transmission resource used for transmitting the SRS is an SRS drop resource.

摘要： Provided are a base station, a terminal whereby erroneous detection of control information can be reduced to prevent the degradation of the system throughput. A PDCCH generation unit (104) forms a downstream allocation control information unit (i.e., DCI) including cyclic redundant check (CRC) bits, which have been masked or scrambled by use of ID information of a terminal (200), and further including a bit sequence (i.e., virtual CRC) known between the terminal (200) and the base station; and an allocation unit (108) and a multiplex unit (109) map the formed DCI to a resource region (i.e., R-PDCCH region) that can be used as any one of a downstream control channel region and a downstream data channel region. That is, the PDCCH generation unit (104) includes the virtual CRC into the DCI only when the DCI addressed to the terminal (200) is mapped to the R-PDCCH region.

摘要： Provided is a multicarrier communication apparatus by which information quantity of CQI reporting can be reduced. In the apparatus, each CQI is recorded in a CQI table section (122) by being classified into a plurality of CQI groups by following a certain rule. A CQI selecting section (123) estimates fluctuation range and variance of reception qualities of the entire resource block to be reported, based on an SINR value outputted from a quality level calculating section (121). Then, based on the estimated values, the CQI selecting section selects a suitable CQI group in a first step, selects a suitable CQI value from among the CQIs included in the selected CQI group in a second step, and outputs the ID of the selected CQI group and the selected CQI value to a CQI generating section (124). Based on such information, the CQI generating section (124) generates a CQI frame to be transmitted to a base station.
