A mobile station transmits to a base station a plurality of pre-coding indicators using respective feedback schemes of a plurality of kinds of feedback schemes that can be set simultaneously by the base station. The mobile station receives from the base station a downlink signal on which pre-coders corresponding to one of the transmitted pre-coding indicators have been applied, and a pre-coder confirmation representing whether the corresponding pre-coders have been applied. The pre-coders represented by the pre-coder confirmation are associated with one of the plural feedback schemes. |
