摘要： Provided are a radio transmission device and a radio transmission method which can reduce the transmission packet collision generation ratio even when no resource allocation signal is detected in retransmission. When control information outputted from a decoding unit (204) contains NACK and retransmission Grant, a retransmission resource check unit (205) determines that the resource indicated by the retransmission Grant is the retransmission resource. Moreover, when no retransmission Grant is detected and the initial transmission is a wideband transmission, the retransmission resource check unit (205) determines that no retransmission resource exists and instructs an RB allocation unit (209) to stop retransmission. Moreover, when no retransmission Grant is detected and the initial transmission is a narrow band transmission, a predetermined resource is determined to be the retransmission resource.

摘要： A wireless communication apparatus by which the orthogonality between the pilot signal sequences between adjacent sectors or cells can be prevented from collapsing due to a frequency selectivity fading. In this apparatus, modulating parts (102-1 to 102-m) modulate encoded data to generate data symbols, and a pilot symbol generating part (103) modulates a received pilot signal sequence to generate pilot symbols. A multiplexing part (104) time multiplexes the pilot symbols and the data symbols. Orthogonal Variable Spreading Factor (OVSF) sequences are used as the pilot signal sequences. The pilot symbol generating part (103) receives an OVSF sequence, among a plurality of OVSF sequences having the same sequence length but being orthogonal to each other, which is orthogonal to an OVSF sequence used as a pilot signal sequence in an adjacent sector and which is orthogonal to that OVSF sequence in a unit shorter than the sequence length.

摘要： A modulating device capable of generating an OFDM signal and having a drastically improved frequency use efficiency. The modulating device has modulators (6, 8 (11, 13, 106, 108, 111, 113)) for modulating a signal to be modulated and having a Nyquist roll-off frequency characteristic with a carrier frequency having a difference two times the Nyquist frequency and combiners (10(15, 110, 115)) for generating modulation output having a speed two times that of the signal to demodulated and the same Nyquist roll-off slope as the signal to be modulated by combining the outputs of the modulators (6, 8 (11, 13, 106, 108, 111, 113)). Thus a double speed wave can be superposed on the same frequency without varying the roll-off slope of the Nyquist characteristic, and therefore an OFDM signal (19) having a drastically improved frequency use efficiency is provided.

摘要： Provided is a sequence allocation method capable of reducing inter-cell interference of a reference signal when a ZC sequence is used as the reference signal in a mobile communication system. In the sequence allocation method divides R×M sequences specified by a ZC sequence number r (r=1 to R) and a cyclic shift sequence number m (m=1 to M) into a plurality of sequence groups X (X=1 to R) in accordance with the transmission band width of the reference signal, so that the ZC sequence is allocated to each cell in each sequence group unit. When it is assumed that R=9 and M=6, the number of sequence is 54. Each of the sequence groups is formed by two sequences. Accordingly, the number of sequence groups is 27. The 27 types of sequence groups are allocated to each cell.

摘要： There are provided a wireless communication apparatus, a wireless communication method, and a wireless communication system capable of selectively utilizing the advantages of both centralized control and distributed control while a time needed for cell searching is suppressed. FIG. 4(a) 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 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 as a centralized control resource, a mobile station can specify sub-frame timing by using only the centralized control resource.

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： A relay transmission method for communication between a base station and a mobile station via a relay station while producing a diversity effect even if the relay station detects an error in the relay signal. A decoding section (104) of the relay station used in this method performs error-correction decoding of a systematic bit by using a parity bit by repetition decoding such as turbo decoding and acquires the results of the decoding composed of the systematic bit having undergone the error-correction decoding. An error judging section (105) judges whether or not any error is present in the decoding results. Coding section (106) performs error-correction coding of the decoding results and acquires the error-correction coded systematic bit and parity bit. A selecting section (107) selects either the decoding results inputted from the decoding section (104) or a bit sequence inputted from the coding section (106) according to the result of the judgment by the error judging section (105) and outputs the selected one to a modulating section (108). A transmission control section (112) controls the operation of a radio transmitting section (109) according to the SNR of the received data symbol and the result of the judgment by the error judging section (105).
