SIGNATURE MANAGEMENT FOR THE UPLINK RANDOM ACCESS CHANNEL

摘要

In a mobile communication system in which a mobile station apparatus (200) uses a signature from a predetermined 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).
