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： A data communication apparatus, a data receiving apparatus, a data transmitting apparatus and a retransmission control method wherein the transmission efficiency is improved. The data communication apparatus includes an error rate determining part (120) and an ACK/NACK generating part (122). The error rate determining part (120) determines the packet error rate of received packet data. The ACK/NACK generating part (122) compares the determined packet error rate with a desired packet error rate that is a target value. As a result of the comparison, if the determined packet error rate is lower than the desired packet error rate, the ACK/NACK generating part (122) generates an ACK signal as a process of avoiding any data retransmission.

摘要： A mobile station wherein the power consumption can be suppressed. In a frame 3, this mobile station (100) transmits, to both a base station (200) and a relay station (150), a multicarrier signal comprising a plurality of subcarriers that have been controlled in transmission power on the basis of reception quality information 1 (Processes (3) and (3)′: first transmission).

摘要： A wireless transmission apparatus capable of suppressing a reduction in coverage area of a base station apparatus and improving the transmission rate in the coverage area. According to this apparatus, a mobile station (10) generates a transport signal addressed to a base station (30) and transmits it to a plurality of relay stations (20-1,20-2), each of which then generates a relay signal from the transport signal and transmits the relay signal to the base station (30). A relay instructing part (115) of the mobile station (10) decides first and second different instructions having their respective instruction contents for the generation of the relay signals. The relay instructing part (115) then sends the first instruction to the relay station (20-1), which is one of the plurality of relay stations (20-1,20-2), while sending the second instruction to the relay station (20-2), which is another one of the plurality of relay stations (20-1,20-2).

摘要： A wireless communication system enabling multihop communication while maintaining the system throughput and preventing degradation of the user throughput. In the system, a BS (base station) determines the relaying method (whether an RS performs reproduction relay or nonreproduction relay) of the RS (relaying station) and the MCS of multihop communication according to the reception quality (the line quality among an MS2, the RS, and the BS) of the pilot for nonreproduction relay, the reception quality (the line quality between the RS and the BS) of the pilot 2 for reproduction relay, and the line quality (the line quality between the MS2 and the RS) measured at the RS. The determination result is transmitted as relay information to the RS and to the MS2 (a mobile station (2)) through the RS. The MS2 encodes and modulates the uplink data with the MCS based on the relay information and transmits the data to the RS. The RS relays the uplink data while selecting nonreproduction relay or reproduction relay according to the relay information.
