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： A radio transmitting apparatus and a radio transmitting method wherein the throughput is improved and a fast initial access processing including an RA burst is accomplished. According to these apparatus and method, a signature table storing part (101) has a plurality of signature groups generated from a plurality of different Zadoff-Chu sequences with a set of signatures generated from one Zadoff-Chu sequence being one signature group.

摘要： Provided are a radio communication mobile station apparatus, a radio communication base station apparatus and a radio communication method, which make it possible to correctly switch between transmission modes for a PUSCH and a PUCCH while impeding signaling overhead from increasing. A transmission mode setting unit (107) detects an instruction given by a base station, the instruction indicating a multiplexing method for a PUSCH and a PUCCH. A trigger information reporting determination unit (108) performs threshold discrimination where PHR_pucch, which is calculated by PHR_control calculation unit (106), is compared with a threshold value that depends on the multiplexing method indicated by the instruction given by the base station. Specifically, in a TDM transmission mode, trigger information is reported if PHR_pucch>X1[dBm] is satisfied. On the other hand, in an FDM transmission mode, the trigger information is reported if PHR_pucch

摘要： Disclosed are a wireless communication base station device, a wireless communication terminal device, and a wireless communication method with which the amount of signaling is reduced while maintaining a high scheduling gain. A judgment unit (117) stores in advance a correspondence between the number of code words and the number of clusters to reduce the maximum value for the number of clusters allocated to each terminal as the number of code words increases, and thus determines the maximum value for the number of clusters based on the number of code words acquired. Based on the number of code words for a transmission signal from a terminal, an estimated value for the reception quality that is output by an estimation unit (109), and the maximum value for the number of clusters that is output by the judgment unit (117), a scheduling unit (118) schedules the allocation of the transmission signal transmitted by each terminal to a transmission band frequency (frequency resource) so as not to exceed the maximum value for the number of clusters.

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.

摘要： A radio transmission device and a radio communication method employ sequence length decision units which hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. A decision is made as to which of the cyclic extension process or the truncation process is to be executed on a Zadoff-Chu sequence according to the sizes of the acquired transmission bandwidth information and the basic sequence length. Then, a difference between the transmission bandwidth and the basic sequence length, i.e., the number of possible cyclic extension/truncation symbols, is obtained.

摘要： It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit (112) stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, W2} to be multiplied on the reference signal. A complex coefficient multiplication unit (113) reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit (112) and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.
