摘要： It is possible to provide a radio transmission device and a radio transmission method which can avoid degradation of a channel estimation accuracy using a reference signal formed by a ZC sequence even when the RS transmission band of a local cell is different from that of an adjacent cell. A mobile station decides a cyclic shift sequence corresponding to RB allocation information from an RS table which correlates different frequency bandwidths from a reference point of respective transmission bands to a spectrum start number of the cyclic shift sequence so as to satisfy a particular relationship based on the sequence length and transmits the decided cyclic shift sequence as RS to a base station. The base station uses the same RS table as the RS table of the mobile station and performs correlation calculation of the RS transmitted from the mobile station, thereby performing channel estimation.

摘要： Provided is a radio communication base station device capable of obtaining a large multi-user diversity effect while suppressing increase of overhead of a communication signal. The radio communication base station device includes a scheduler (101) which performs scheduling for allocating RB (Resource Block) to terminals belonging to a first group by FSA (Frequency Scheduled Allocation) in accordance with line quality of each terminal and each RB and allocating remaining RB other than the RB allocated to the terminals belonging to the first group, to terminals belonging to a second group according to a predetermined allocation rule. That is, the scheduler (101) performs RB allocation to the terminals belonging to the first group with a higher priority than RB allocation to the terminals belonging to the second group. Each time the scheduler (101) performs FSA, it outputs the result of the FSA to the terminals belonging to the first group to an encoding unit (102) and an extraction unit (111) and does not output any scheduling result to the terminals belonging to the second group.

摘要： A wireless communication terminal apparatus wherein the occurrences of inter-sequence interferences between a reference signal preceding a sequence hopping and a reference signal following the sequence hopping can be reduced so as to improve the randomizing effect achieved by the sequence hopping. In this apparatus, a sequence number deciding part (105) has a table in which the sequence lengths of Zadoff-Chu sequences used for reference signals are associated with the sequence numbers of Zadoff-Chu sequences used for reference signals of a slot #1 and with the sequence numbers of Zadoff-Chu sequences used for reference signals of a slot #2. In accordance with a sequence length according to a transmission bandwidth received from a decoding part (104), the sequence number deciding part (105) refers to the table to decide the sequence number of a Zadoff-Chu sequence. In the table of the sequence number deciding part (105), different hopping amounts are provided to a plurality of slot-#2-specific Zadoff-Chu sequences having different sequence lengths.

摘要： Disclosed are a radio transmission device and a radio transmission method which can reduce a processing amount or a memory amount while maintaining the randomizing effect of other cell interference. When using as a reference signal, a ZC sequence of the sequence length uniquely correlated to a transmission bandwidth of a reference signal, as the transmission bandwidth becomes smaller and the sequence length of the ZC sequence becomes shorter, the sequence is switched at a shorter time interval and as the transmission bandwidth becomes greater and the sequence length of the ZC sequence becomes longer, the switching is performed at a longer time interval. Thus, a reference signal is generated by using the ZC sequence in accordance with the timing into which the reference signal transmission bandwidth and the sequence are switched.

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. A signature sequence assignment control part (102) switches signature groups to be assigned to a UE for each of paging transmissions, thereby assigning a signature sequence, which is to be used for an initial RA, from the same signature group. A paging information generating part (104) causes the ID of the assigned signature sequence to be included into paging information, which is then transmitted to the UE.
