摘要： Disclosed is a frequency band allocation method which reduces PAPR (peak to average power ratio) when performing a single carrier transmission in the uplink line of an LTE+ (LTE Advanced) system in a system using both of an LTE (Long Term Evolution) system and the LTE+ system. In the frequency band allocation method, a UL band for the LTE is arranged adjacently in a lower frequency band than the UL band for the LTE+. With this arrangement, it is possible to prevent division of the band for the LTE+ by the uplink line control channel (such as PUCCH) transmitted by an LTE mobile station and to allocate a wide band continuously with the LTE+ mobile station. Especially when the LTE+ mobile station performs a single carrier transmission with the uplink line, the PAPR can be reduced since it is possible to allocate a band continuous with the single carrier signal.

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.

摘要： A relay station and a wireless communication system wherein novel retransmission control is achieved in cases when a TTI-bundling technique and a relay technique are used in communication between a terminal and a base station. A relay station (300) relays wireless communication between a terminal that transmits a wireless signal in which code words obtained by encoding a single set of transmission data have been mapped to a TTI bundle consisting of a plurality of TTIs, and a base station that receives the wireless signal and transmits error detection information related to the code word transmitted in the tail TTI of the TTI bundle. At the relay station (300), a control information generating unit (309) transmits error detection information related to the code word transmitted in the front TTI of the TTI bundle.

摘要： Disclosed is a radio communication device that, even when a terminal erroneously receives a retransmission grant or a response signal from a base station, can reduce the number of other terminals in which the terminal interferes at a retransmission. In this device, a determination unit (205) determines a bandwidth between the two ends of a transmission band allocated to a transmitted signal at the retransmission of the transmitted signal. An allocation unit (209) allocates the transmitted signal to a frequency resource based on the bandwidth that is input from the determination unit (205). The determination unit (205) increases at the retransmission the amount of decrease in the bandwidth from the previous transmission, as the consecutiveness of the transmitted signal in the frequency region decreases.

摘要： A wireless communication apparatus, method, and system selectively utilize advantages of both centralized control and distributed control while suppressing cell searching time. FIG. 4(a) represents an example in which a P-BCH (Primary Broadcast Channel) and an S-SCH (Secondary Synchronization Channel) for centralized control and a P-BCH and an S-SCH for distributed control are frequency-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a distributed control resource. FIG. 4(b) represents an example in which a P-BCH and an S-SCH for the centralized control and a P-BCH and an S-SCH for the distributed control are time-divided, and the P-BCH and the S-SCH for the distributed control are transmitted to a centralized control resource. Since a relay station transmits the P-SCH (Primary Synchronization Channel) as a centralized control resource, a mobile station can specify sub-frame timing by using only the centralized control resource.
