Abstract: A mobile station comprises a receiver and a processor. The receiver is configured to receive, from a base station, allocation information indicating one or a plurality of allocated resource block(s) of uplink which are consecutive in a frequency domain. The processor is configured to determine, based on the allocation information, one of the resources of downlink, to which an ACK or NACK signal is distributively mapped onto a plurality of resource elements in subcarrier groups. The subcarrier resources within subcarrier group are consecutive in frequency domain and nonconsecutive in the frequency domain among subcarrier groups.

Abstract: A terminal apparatus includes processing circuitry to duplicate a transmission packet to generate duplicated transmission packets and to assign the duplicated transmission packets to a subcarrier resource for a random access channel. A transmitter in the terminal transmits the duplicated transmission packets using the subcarrier resource for the random access channel.

Abstract: A terminal apparatus includes a receiving section to receive information, where the information specifies a number, and a generating section to generate, based on the number, a transmission signal including access signals which are consecutive in a time domain and which include an access signal and at least one duplication of the access signal. The access signals are identical in number to the number specified by the information. A transmitting section transmits the transmission signal on at least two consecutive time slots using a resource selected from resource candidates.

Abstract: A terminal apparatus and retransmission control method reduces overhead of the uplink control channel in cases when ARQ is applied in communication that uses an uplink unit band and a plurality of downlink unit bands associated with the uplink unit band. A first condition is set in which downlink assignment control information is transmitted from a base station by a unit band group which comprises a basic unit band, which is the downlink unit band on which a broadcast channel signal including information relating to the uplink unit band is transmitted, and a second downlink unit band other than the basic unit band. A bundling unit will not transmit a response signal to the base station in certain cases.

Abstract: A wireless communication method and apparatus are provided for selecting quality-reporting sub-carrier bands based on sub-carrier band quantity information received from a base station. The method includes generally four steps. First, from a base station, information indicating quantity of sub-carrier bands is acquired. Second, channel quality of each of a plurality of sub-carrier bands within a communication band is measured from a received signal. Third, sub-carrier bands are selected from the plurality of sub-carrier bands, wherein quantity of the selected sub-carrier bands corresponds to the quantity of sub-carrier bands indicated by the acquired information. Fourth, information indicating channel quality of the selected sub-carrier bands is reported to the base station.

Abstract: A radio communication apparatus includes spreading circuitry that spreads a response signal using a first set of orthogonal sequences to produce a spread response signal. Each orthogonal sequence in the first set has a first length. The spreading circuitry also spreads a reference signal using a second set of orthogonal sequences to produce a spread reference signal. Each orthogonal sequence in the second set has a second length that is shorter than the first length. A radio transmitter transmits the spread response signal and the spread reference signal.

Abstract: A wireless communication apparatus and method minimizes degradation in a separation characteristic of a code-multiplexed response signal using two-dimensional processing. One of plural cyclic shift values defines a reference signal sequence that is spread with an orthogonal sequence associated with one of the plural cyclic shift values. This two-dimensional processing compensates for interference affecting the reference signal.

Abstract: Random access technology is provided for establishing an individual channel between a radio communication terminal device and a base station device in a short time and a radio communication terminal device executing the random access method. A RACH sub-channel allocation unit allocates a transmission packet input from a replication unit to an arbitrary sub-carrier at the RACH arbitrary time slot at random. An allocation unit judges whether an overlap is generated in the allocation result obtained by the RACH sub-channel allocation unit.
