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.

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.

摘要： A wireless communication apparatus and an error detection result feedback method wherein unnecessary retransmissions are avoided to improve the system throughput. At a base station (200), a decoding unit (205) decodes code words, which have been mapped to a TTI bundle, for the respective TTIs in the TTI bundle. An error detecting unit (206) detects errors in the decoding results. A control information generating unit (209) sequentially transmits, in accordance with detection timings, error detection result information related to the code word transmitted in the tail TTI in the TTI bundle, as well as error detection result information related to the code word transmitted in at least one of the other TTIs. In this way, an apparatus that transmits the code words can use the result of error detection in the tail TTI as a reference used for deciding the execution of a retransmission, so that unnecessary retransmissions can be avoided.
