Abstract: A wireless communication method and apparatus are provided for selecting quality-reporting sub-carriers based on sub-carrier quantity information received from a base station. The method comprises: acquiring information indicating a number of sub-carriers; measuring channel quality of each of a plurality of sub-carriers within a communication band from a received signal; selecting sub-carriers satisfying a condition related to measured channel quality bands from the plurality of sub-carriers, wherein quantity of the selected sub-carriers corresponds to the quantity of sub-carriers indicated by the acquired information; and transmitting information indicating channel quality of the selected sub-carriers.

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.
