    摘要： A receiver apparatus wherein the processing amount for CQI (Channel Quality Indicator) measurements in a communication system having a plurality of system bandwidths can be reduced. In this apparatus, a narrow band CQI measurement part (109) measures, as a narrow band CQI, the CQI in resource blocks the number of which is required for the CQI measurement from the start position of a narrow bandwidth transmitted from a transmitter apparatus; a wide band CQI measurement part (110) extracts, from a system bandwidth transmitted from the transmitter apparatus, resource blocks the number of which is required for the CQI measurement, and then measures, as a wide band CQI representative of the channel quality of the whole system bandwidth, an average CQI in the extracted resource blocks; and a feedback information generating part (111) generates feedback information including both the narrow band CQI and the wide band CQI.

    摘要： In order to provide a transmission device and transmission method with which a response signal for random access preamble transmitted from a preamble transmission device is efficiently transmitted, setting unit (101) in base station (100) sets a first resource candidate group, which enables terminal (200) capable of receiving a latch response transmitted by demodulation reference signal (DMRS) transmission to be selected, and a second resource candidate group, which enables terminal (300) incapable of receiving a latch response transmitted by DMRS transmission but capable of receiving a latch response transmitted by cell-specific reference signal (CRS) transmission to be selected. Control unit (103) selects DMRS transmission as the latch response transmission method when a resource in which latch preamble has been received is included in the first candidate group, but selects CRS transmission as the latch response transmission method when the resource is included in the second resource candidate group.

    摘要： The objective of the present invention is to provide a terminal device capable of suppressing delay in switching between transmit/receive points, and of reliably switching between the transmit/receive points. In the device, a reception processing unit (203) receives control information including a transmission request for an A-SRS and a report request for a downlink CSI, whereupon a transmission signal formation unit (207) transmits the A-SRS at a transmission power set on the basis of the report request. In addition, if a report for each downlink CSI between a plurality of base stations is requested in the report request, the transmission signal formation unit (207) transmits the A-SRS at a first transmission power, whereas if a report for a downlink CSI between a single cell is requested in the report request, the A-SRS is transmitted at a second transmission power. The first transmission power is greater than the second transmission power.

    摘要： Provided are a base station, a mobile station, a method for transmitting calculation parameters for a power headroom and a method for transmitting a power headroom capable of increasing the accuracy of link adaptation by reducing the probability that a power headroom value is out of a reported range. In a base station (100), a PHR bandwidth notifier (105) determines a bandwidth for power headroom calculation to be used for calculating a power headroom by a mobile station (200) for a component carrier to which an unlink allocation signal (UL grant) is not mapped and generates a notification signal containing information on the determined bandwidth for power headroom calculation, and a transmitting means (modulator (106), transmission RF unit (107)) transmits the generated notification signal to the mobile station (200). Specifically, the PHR bandwidth notifier (105) determines a bandwidth for PHR calculation according to an estimated path-loss level.

    摘要： This invention relates to a transmitter apparatus, a receiver apparatus, a transmission method and a notification method that, when a switching between MIMO communication and non-MIMO communication is performed, can suppress the increase of an SRS (Sounding Reference Signal) resource, while suppressing the degradation of trackability of temporal variation of a channel. In a terminal (200), a mapping unit (212) maps an SRS sequence, which is received from a pilot, generating unit (216), on the basis of information related to an SRS hopping pattern, received from a base station (100). For this SRS hopping pattern, the frequency of the SRS transmissions via a first one of a plurality of antennas of the terminal (200) is higher than that of the SRS transmissions via a second one of the plurality of antennas of the terminal (200).

    摘要： Provided are a wireless communication terminal apparatus, a radio communication base station apparatus and a wireless communication method whereby the increase in the number of signaling bits can be suppressed, while the SRS capacity can be improved. RS type determining unit (105) determines, based on scheduling information, that the signal is an SRS signal accompanied by no data or a DMRS signal accompanied by data. CS amount deciding unit (106) holds a CS amount for DMRS and a CS amount for SRS that are defined such that the CS amount for SRS includes a CS amount not included in the CS amount for DMRS. The CS amount deciding unit (106) uses CS amount notification information, which is included in the scheduling information, and the CS amount definition to derive a CS amount in accordance with the RS type outputted from the RS type determining unit (105).
