Abstract: A user terminal apparatus includes a receiver to receive a control information value belonging to a set of multiple control information values. Each control information value in the set of multiple control information values is associated with a subset of random access sequences from multiple subsets of random access sequences. Different ones of the multiple subsets of random access sequences are associated with different amounts of data. A data processor selects a random access sequence from one of the subset of random access sequences based on the control information value. A transmitter transmits the selected random access sequence.

Abstract: Provided is a communication device, which is enabled to improve the throughput of a communication system by reducing the difference of a transmission power between an SCCH and an SDCH thereby to satisfy the required quality of a PAPR. In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS1) of the SDCH, an MCS pattern (MCS2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS2 and the MCS1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and the SDCH thereby to generate a transmission signal.

Abstract: A user terminal apparatus includes a receiver to receive control information, and a data processor, coupled to the receiver, to select a sequence from a subset of different sequences. The difference sequences are based on a base sequence, and the subset of different sequences depends on the control information. The different sequences are respectively associated with different message sizes or different radio conditions at the user terminal apparatus, have different cyclic shifts, and are arranged in an order of increasing cyclic shift. A transmitter, coupled to the data processor, transmits the selected sequence.

Abstract: 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.

Abstract: A radio performs random access by receiving control information and grouping a predetermined number of sequences that are generated from a plurality of base sequences into a plurality of groups by partitioning the predetermined number of sequences. At least one of the groups is associated with a first respective range of data amounts and a first respective range of reception qualities. Sequences generated from a common base sequence are arranged in an increasing order of respective cyclic shifts associated with the sequences. A sequence is randomly selected from a plurality of sequences contained in one group of the plurality of groups. A position at which the predetermined number of sequences are partitioned is determined based on the control information. A number of sequences contained in each of the plurality of groups varies in accordance with the control information.

Abstract: Apparatus for use in a mobile radio station includes a memory to store a table of adaptable associations between control information and code sequences. A data processor detects a condition and dynamically adapts one or more of the associations in the table stored in memory between control information and code sequences depending on the detected condition. A transmitter transmits one of the code sequences selected based on the dynamically adapted one or more of the associations.

Abstract: Provided is a radio communication device which can suppress inter-code interference between an ACK/NACK signal and a CQI signal which are code-multiplexed. A diffusion unit (214) diffuses the ACK/NACK signal inputted from a judgment unit (208) by using a ZC sequence. A diffusion unit (219) diffuses the CQI signal by using a cyclic shift ZC sequence. By using a Walsh sequence, a diffusion unit (216) further diffuses the ACK/NACK signal which has been diffused by using the ZC sequence. A control unit (209) controls the diffusion unit (214), the diffusion unit (216), and the diffusion unit (219) so that the minimum value of the difference between the CQI signals from a plurality of mobile stations and a cyclic shift amount of the ACK/NACK signal is not smaller than the minimum value of the difference between the cyclic shift amounts of the ACK/NACK signals from the plurality of mobile stations.
