TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

摘要

When one serving cell is configured, and a frame structure type is FDD, one value among values of {2, 5, 10, 20, 40, 80, 160, 32, 64, and 128} subframes is configured as a CSI reporting period. When the one serving cell is configured, and the frame structure type is TDD, one value among values of {1, 5, 10, 20, 40, 80, and 160} subframes is configured as the CSI reporting period. When the two serving cells or more are configured, one value among values of {5, 10, 20, 40, 80, and 160} subframes is configured as the CSI reporting period.

1. A base station apparatus comprising:
a higher layer processing unit that configures one serving cell or a plurality of serving cells which include two serving cells or more having different frame structure types, and configures a parameter relating to periodic reporting of channel state information; and a reception unit that receives the channel state information which is periodically reported, based on a period and an offset of a subframe which are determined by the parameter, wherein one value among values of {2, 5, 10, 20, 40, 80, 160, 32, 64, and 128} subframes is configured as the period when the one serving cell is configured, and the frame structure type is FDD, one value among values of {1, 5, 10, 20, 40, 80, and 160} subframes is configured as the period when the one serving cell is configured, and the frame structure type is TDD, and one value among values of {5, 10, 20, 40, 80, and 160} subframes is configured as the period when the two serving cells or more are configured and the frame structure type in a primary cell is FDD.
