Title:
A user terminal, a base transceiver station, and a wireless communication method
Document Type and Number:
Japanese Patent JP6101311
Kind Code:
B2
Abstract:
The present invention is designed so that it is possible to feed back HARQ-ACKs adequately and prevent the decrease of communication quality even when a plurality of component carriers are configured in a radio communication system. According to one aspect of the present invention, a user terminal has a transmission section that transmits ACK/NACK in response to DL signals transmitted from a plurality of cells, a receiving section that receives information about cells to be scheduled, and a control section that controls transmission of the ACK/NACK based on the information about the cells to be scheduled.
