摘要： This invention provides a terminal apparatus that can suppress the quality degradation caused by a propagation path variation when implementing a retransmission control method using non-adaptive HARQ in a wireless communication system utilizing the MIMO communication technique. In this apparatus, a number-of-retransmissions counting unit (105) counts a number of retransmission requests (L) for the same code word. A predetermined precoder designating unit (106) changes precoders between when the number of retransmission requests (L) is less than N and when the number of retransmission requests (L) is equal to or greater than N plus one. A PDCCH generation unit (211) determines, based on a result of comparison between the number of retransmission requests (L) for the same CW and the number of retransmission requests (N) established for the change of precoders, a precoder to be used by terminals, and further allocates, based on the determined precoder, resources to the plurality of terminals.

摘要： Disclosed are a wireless communication method, a wireless communication base station device, and a wireless communication terminal device that dynamically switch the transmission slot of an SRS of each terminal within a cell while suppressing an increase in the number of signaling bits. A terminal (100) and a base station (200) are each provided with a table wherein FH flags for SRS and transmission power data of each slot are mapped to two-bit notification bits. In this table, transmission power data indicating SRS transmission by slot 1 and slot 2 and FH flags are mapped, and an FH flag is not mapped to transmission power data indicating SRS transmission by slot 1 or slot 2. The base station (200) notifies the terminal (100) of the FH flag data and the SRS transmission power data by means of transmitting scheduling data containing the notification bits to the terminal (100).

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 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 on the basis of CSI-RS allocation information, measures channel quality such as CQI, PMI or M by using this CSI-RS, and transmits and reports feedback information containing channel quality information to a transmission apparatus.
