Abstract:
1. A mobile station apparatus configured to communicate with a base station apparatus on a plurality of serving cells, the mobile station apparatus comprising: a determining unit configured to determine a number of bits of HARQ information based on a number of downlink subframes corresponding to an uplink subframe in which the HARQ information is transmitted, a number of serving cells configured, and a transmission mode configured in each serving cell; an applying unit configured to apply spatial bundling to the HARQ information in a case where the determined number of bits of the HARQ information exceeds a predetermined value; and a coding unit configured to select one of a first coding scheme and a second coding scheme based on the number of bits of the HARQ information to which the spatial bundling has been applied and a number of bits of a scheduling request, and to encode both the HARQ information and the scheduling request using the selected coding scheme, wherein the first coding scheme is a method for encoding a bit sequence obtained by concatenating the bits of the HARQ information and the bits of the scheduling request, and the second coding scheme is a method for separately encoding respective bit sequences which are obtained by dividing a bit sequence, the bit sequence is generated by concatenating the bits of the HARQ information and the bits of the scheduling request.
