摘要： A radio transmitting apparatus and a radio transmitting method wherein the increase of the guard time in a random access region is reduced to secure the data transmitting region of an upstream line. In this apparatus, when a received signal power estimated by a received signal power estimating part (205) is the higher, a RACH format selecting part (206) selects a RACH format having the longer frame length. Contrarily, when a received signal power estimated by the received signal power estimating part (205) is the lower, the RACH format selecting part (206) selects a RACH format having the shorter frame length. A RACH data part arranging part (207) appropriately selects, in accordance with the selected RACH format, top-priority information, such as terminal identifiers, priority information, such as connection request information or band assignment request information, and non-priority information and arranges RACH data parts.

摘要： Provided are a radio transmission device and a radio transmission method, which prevent the deterioration of a preamble detecting performance while reducing the collision probability of a RACH. In this radio transmission device, a Signature table storage unit (103) divides the magnitudes of transmission loss levels into individual levels corresponding to the distances from a base station, to cause CAZAC series and circulation shift quantities to correspond to each other at the individual levels, and is provided with a table containing a plurality of Signatures created from the CAZAC series and the circulation shift quantities caused to correspond to each other. A Signature selecting unit (104) selects one of the corresponding Signatures at random from the Signature table storage unit (103), on the basis of the magnitude of the transmission loss level outputted from a transmission loss level deciding unit (102). A RACH signal generating unit (105) generates the RACH signal with the Signature selected.

摘要： A wireless communication base station apparatus capable of suppressing the waste of a signaling source in retransmittal signaling of group scheduling. In this apparatus, a multiplexing part (101) multiplexes ACK or NACK signals to be transmitted to a plurality of terminals belonging to a plurality of groups for initial transmittals, thereby generating ACK/NACK multiplexed signals. A multiplexing part (102) multiplexes the group ID of one retransmittal group associated with the plurality of groups for initial transmittals with control information directed to retransmittal terminals that are some of the plurality of initial transmittal terminals and with the ACK/NACK multiplexed signals generated by the multiplexing part (101), thereby generating a control information multiplexed signal. A mapping part (107) maps the control information multiplexed signal generated by the multiplexing part (102) into PDCCH. A radio transmitting part (110) transmits, via a transmission antenna (111), the control information multiplexed signal mapped in the PDCCH.

摘要： A mobile station apparatus includes a receiving unit configured to receive control information; a selecting unit configured to randomly select a sequence from a plurality of sequences contained in one group of a plurality of groups, into which a predetermined number of sequences generated from a plurality of base sequences are grouped and which are respectively associated with different amounts of data or reception qualities; and a transmitting unit for transmitting the selected sequence. The predetermined number of sequences are grouped by partitioning the predetermined number of sequences, in which sequences generated from the same base sequence and having different cyclic shifts are arranged in an increasing order of the cyclic shifts. A position at which the predetermined number of sequences are partitioned is determined based on the control information, and a number of sequences contained in each of the plurality of groups varies in accordance with the control information.

摘要： Provided is a radio communication device which can reduce the affect of inter-cell interference using a small reception process amount. The radio communication device includes a sequence number setting unit (101) which sets a sequence number for a ZAC sequence used for spreading a response signal and another sequence number for a ZAC sequence used for a reference signal in a ZAC sequence generation unit (102) and a ZAC sequence generation unit (109), respectively. The ZAC sequence generation unit (102) generates a ZAC sequence of the set sequence number from the sequence number setting unit (101). A spread unit (104) spreads the response signal. The ZAC sequence generation unit (109) generates a set ZAC sequence from the sequence number setting unit (101) and outputs the ZAC sequence as a reference signal to an IF FT unit (110). A sequence number setting unit (101) changes the sequence number at a transmission switching timing between the response signal and the reference signal.

摘要： It is possible to provide a radio transmission device and a radio transmission method capable of improving resource use efficiency without increasing or decreasing the number of Signatures. The device and the method use a Signature table having Access types, DL CQI, and Signatures uniquely correlated to one another. In this Signature table, the DL CQI level is set for each Access type in accordance with the data amount transmitted/received before a data communication start after a transmission of RACH. When the Access type is IDLE, the data amount is greater as compared to other Access types and the DL CQI is set to level 1 to 6. When the Access type is ACTIVE, the data amount is smaller as compared to other Access types and the DL CQI is set to smaller than level 3 and greater than level 4. Furthermore, when the Access type is Handover, the data amount is middling as compared to other Access types and the DL CQI is set to level 1 to 3 or above.
