摘要： A mobile station (MS) obtains a parameter, performs transmission of a preamble, and sets a counter incremented based on transmission of the preamble. The MS is able to indicate a random access problem corresponding to one transmission timing cell group in a case where the counter reaches the parameter +1 and the transmission of the preamble is performed on the one transmission timing cell group, where the one transmission timing cell group being one of the plurality of transmission timing cell groups, and the MS is able to not indicate a random access problem corresponding to another transmission timing cell group in a case where the counter reaches the parameter +1 and the transmission of the preamble is performed on the another transmission timing cell group, where the another transmission timing cell group being one of the plurality of transmission timing cell groups.

摘要： To prevent a collision from occurring at the time of random access in cases such as handover, response to paging and the like where a mobile station apparatus performs random access in response to directions from a base station apparatus. In a mobile communication system in which a mobile station apparatus 200 uses a signature of a beforehand determined signature group at the time of random access with a base station apparatus 100, the signature group is comprised of a signature group managed by the base station apparatus 100 and another signature group managed by the mobile station apparatus 200. The signature group managed by the base station apparatus 100 includes signatures associated with particular random access reasons to be selected by the base station apparatus 100.

摘要： A multicarrier-signal transmitting apparatus comprising a rotation-amount setting unit configured to set a phase rotation amount for each subcarrier of a plurality of subcarrier groups, the phase rotation amount being set with a setting selected from a first setting and a second setting, the first setting being such that the phase rotation amount is different between a subcarrier group and an adjacent subcarrier group within a plurality of adjacent subcarrier groups, and the second setting being such that the phase rotation amount is identical between a subcarrier group and an adjacent subcarrier group within a plurality of adjacent subcarrier groups; and a phase rotator configured to add a phase rotation to reference signals and a data signal of said each subcarrier of said plurality of subcarrier groups based on the phase rotation amount.
