摘要： Provided is a wireless communication apparatus wherein channel estimation accuracy is improved while keeping the position of each bit in a frame, even when a modulation system having a large modulation multiple value is used for a data symbol. In the wireless communication apparatus (100), an encoding section (101) encodes and outputs transmitting data (bit string) to a bit converting section (102), and the bit converting section (102) converts at least one bit of a plurality of bits constituting a data symbol to be used for channel estimation, among the encoded bit strings, into ‘1’ or ‘0’ and outputs it to a modulating section (103). The modulating section (103) modulates the bit string inputted from the bit converting section (102) by using a single modulation mapper and a plurality of data symbols are generated.

摘要： A wireless communication terminal apparatus and a CQI selecting method wherein when CQIs are grouped according to their levels and then an upper-order CQI, which is indicative of a group, is to be informed in a longer period, while a lower-order CQI, which identifies a CQI in the group, being to be informed in a shorter period, the CQI is precisely selected. A reception SIR range of 0-4 dB in UE corresponds to a level 1 of upper-order CQI. A next reception SIR range of 4-8 dB corresponds to a level 2 of upper-order CQI. Similarly, the following SIR ranges up to 24 dB, each of which is 4 dB higher than a respective previous one, correspond to the respective following levels of upper-order CQI. On the other hand, the levels 1-4 of lower-order CQI, with which the level 1 of upper-order CQI is associated, correspond to a SIR range of −1-5 dB. The levels 1-4 of lower-order CQI, with which the level 2 of upper-order CQI is associated, correspond to a SIR range of 2-9 dB. Thus, the SIR ranges, to which the lower-order CQIs correspond, overlap the respective SIR ranges corresponding to the respective adjacent levels of upper-order CQIs with which the lower-order CQIs are associated.

摘要： Provided is a radio communication device which can obtain an error ratio characteristic equivalent to the one obtained by using a tail bit, without using a tail bit in the error correction and encoding. The device includes: a blocking unit (106) which adds a bit indicating an error detection result in a CRC unit (105) to control data (a bit string) so as to constitute an encoded block and outputs the encoded block to an encoding unit (107); and the encoding unit (107) which corrects and encodes the encoded block. The blocking unit (106) forms an encoded block by a bit string of control data and a probability deviation existence bit added to the tail of the bit string.

摘要： A wireless communication device, e.g., a mobile station, capable of performing its communication and relay processing for another mobile station, when requested, at the same time without stopping the communication and the relay processing. In the device, an outgoing/incoming call request detection unit (106) detects an outgoing/incoming call request indicating that an outgoing call of the signal of the mobile station or an incoming call is requested from a signal inputted from an upper-layer processing unit (105). A relay request detection unit (108) detects a relay request signal indicating that an MS1 requests an MS2 for relay to a base station from a demodulated relay signal inputted from a relay signal demodulation unit (107). A communication rate determination unit (109) determines the communication rate so as to simultaneously transmit both the signal of the mobile station and the relay signal when a signal indicating that an outgoing/incoming call request is detected is inputted from the outgoing/incoming call request detection unit (106) or a signal indicating that a relay request signal is detected is inputted from the relay request detection unit (108).

摘要： Disclosed is a radio communication device capable of improving the usage efficiency of resources in multi-stage relay to reduce the amount of delay of a relay signal and improving the reception quality of signals by a relay station or a base station. A transmission determining unit 16 determines whether to transmit the relay signal and whether to transmit ACK/NACK on the basis of whether there is an error in the relay signal, and on the basis of ACK/NACK received from a one-hop-downstream radio communication device. An MCS determining unit 17 provided in the transmission determining unit 16 determines an MCS for the relay signal. A transmission instruction generated by the transmission determining unit 16 is output to a buffer 11 and an ACK/NACK generating unit 19. The determined MCS is output to an error correction coding unit 12 and a modulation unit 13. The ACK/NACK generating unit 19 generates ACK when there is no error in the relay signal, and generates NACK when there is an error in the relay signal.
