Document Type and Number:

WIPO Patent Application WO/2013/105409

Kind Code:

A1

Abstract:

A base station device allocates a plurality of cells to a mobile station device and a communication is carried out between the base station device and the mobile station device via the plurality of cells. The plurality of cells are divided into a plurality of groups formed from at least one cell wherein the transmission timing in the mobile station device is the same. If, by an instruction from the base station device, a cell which is removed from one group among the plurality of groups is added to another group among the plurality of groups, the added cell is set to a deactivated state.
