User terminal, wireless base station and wireless communication method

Title:

User terminal, wireless base station and wireless communication method

Document Type and Number:

Japanese Patent JP6339739

Kind Code:

B2

Abstract:

The present invention is designed so that UL transmission can be made adequately even when transmission of uplink control information using secondary cells (SCells) is made configurable. A user terminal communicates with a radio base station by using carrier aggregation, and has a generating section that generates uplink control information based on a DL signal transmitted from the radio base station, and a control section that controls transmission of the uplink control information, and the control section controls the transmission of the uplink control information by applying simultaneous transmission of an uplink control channel and an uplink shared channel to each of a plurality of cell groups, each including at least one component carrier (CC).
