Abstract:
A base station apparatus assigns a plurality of cells to a mobile station apparatus, and the base station apparatus and the mobile station apparatus communicate with each other via the plurality of cells. The plurality of cells are grouped into a plurality of groups, each group being made up of at least one cell having an identical transmission timing in the mobile station apparatus. In a case where a cell that has been deleted from one of the plurality of groups is added to another one of the plurality of groups in accordance with an instruction from the base station apparatus, the mobile station apparatus sets the added cell to be in a deactivated state.
