摘要： A radio communication apparatus of the present invention aims at improving an error rate characteristic in the end receiver. A repeater (radio relay device) RS2 receives a signal transmitted from a repeater RS1 at a point of time of signal transmission from the repeater RS1, and detects whether or not an error exists in the signal at a point of time of transmission. Also, when the repeater RS2 detects the error from a systematic bit S of the transmitted signal from the repeater RS1, such repeater RS2 generates error position information EI, replace a part of a parity bit P with the error position information EI, and transmits a resultant signal. The error detection result is notified through the control channel. The mobile station (mobile terminal) MS makes an error correction based on the error position information EI, and demodulates the signal by executing an error correction decoding process.

摘要： Provided is a relay transmission method capable of obtaining the diversity effect even when a relay station has detected an error in a relay signal when performing communication between a base station and a mobile station via a relay station. In the relay station used in this method, a decoding unit (104) performs error-correction-decoding of a systematic bit by performing repeated decoding such as a turbo decoding by using a parity bit and obtains a decoding result formed by a systematic bit after the error-correction-decoding. An error judging unit (105) judges whether the decoded result has an error by using CRC (Cyclic Redundancy Check). An encoding unit (106) performs error-correction-encoding of the decoded result and obtains a systematic bit after error-corrected-encoded and a parity bit. A selection unit (107) selects the decoded result inputted from the decoding unit (104) or the bit string inputted from the encoding unit (106) according to the judgment result obtained by the error judging unit (105) and outputs it to a modulation unit (108).

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： In a base station (100), a division number calculating unit (103) calculates the division number of a PRB pair on the basis of a first number of REs capable of mapping an allocation control signal, a second number of REs capable of mapping signals other than the allocation control signal, and a reference value, which is the number of REs satisfying the reception quality request in a terminal (200) for the allocation control signal, in each PRB pair. Then, a control signal mapping control unit (104) determines a search space by determining a control channel element group constituting a plurality of mapping unit resource region candidates within a CCE group obtained by separating each PRB pair contained in a first group into the same number as the division number.

摘要： The present invention pertains to a terminal device, which, when ARQ is used for communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band, and when a transmission mode that supports up to 2 TB in a PCell is set in the terminal, is capable of reducing the amount of signaling from a base station while eliminating a lack of PUCCH resources when semi-permanent scheduling (SPS) is used in the PCell.

摘要： The present invention has an object to provide a wireless communication apparatus and a wireless communication method, which are capable of measuring line qualities as to a plurality of channels in a high efficiency without giving an adverse influence to communications made by other mobile stations in such a case that a mobile station is communicated with a base station via a relay station.In a frame 1, a mobile station “MS” transmits a packet “MS(1)” via a channel “CH1” to a relay station “RS”, and the relay station “RS” transmits a packet “RS[MS(0)]” via a channel “CH2” to a base station. In this case, symbol “MS(1)” indicates a first packet of the mobile station “MS.” Also, symbol “RS[MS(0)]” represents a packet which is relayed by the relay station “RS.” Next, in a frame 2, the channels “CHs” of the frame 1 are traded with each other, and then, packets are transmitted via the traded channels “CHs.” In other words, the mobile station “MS” transmits a packet “MS(2)” via the channel “CH2” to the relay station “RS”, and the relay station “RS” transmits a packet “RS[MS(1)]” via the channel “CH1” to the base station. When the above-described channel trade is performed, the qualities of the channels “CHs” between the mobile station and the relay station can be measured as to the channel “CH1” in the frame 1, and as to the channel “CH2” in the frame 2 by the relay station. As a consequence, it is possible to immediately grasp that the line qualities have been deteriorated.

摘要： A radio communication base station device can efficiently obtain a multiuser diversity gain from frequency scheduling while reducing the amount of a reference signal occupying an uplink. In the device, a grouping section (109) divides a plurality of RBs (Resource Blocks) into a plurality of RB groups. An RB group control unit (108) performs a control to change the correspondence relationship between the RBs and the RB groups with time. When the grouping section (109) divides the RBs into the RB groups, the RB control unit (108) performs a control to change a combination of the RBs included in each of the RB groups with time. A scheduling section (110) performs a scheduling of allocating each of a plurality of mobile stations to each of the RBs in each of the RB groups according to the reception quality of the reference signal.
