As a random access channel (RACH), two types of RACHs, a synchronous RACH and an asynchronous RACH are prepared, condition of a mobile station is classified depending on whether there is temporal synchronization in the mobile station and whether a resource is allocated, and depending on each case, any one of the synchronous RACH/the asynchronous RACH/uplink shared control channel (USCCH) is adaptively selected to carry out connection processing. |
