摘要

A mobile station apparatus performs an efficient random access procedure. A base station apparatus includes all parameters of random access information in setting information regarding at least one of a plurality of cells and part of the parameters of the random access information in setting information regarding at least one of the plurality of cells and transmits the setting information to the mobile station apparatus. The mobile station apparatus executes the random access procedure for the cells for which the random access information is included in the transmitted setting information.
