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 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: 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.
