TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

Title:

TERMINAL DEVICE, BASE STATION DEVICE, AND COMMUNICATION METHOD

Document Type and Number:

WIPO Patent Application WO/2017/188188

Kind Code:

A1

Abstract:

A terminal device (1) receives an uplink grant that is used for scheduling a PUSCH in a serving cell and an uplink grant that is used for scheduling an sPUSCH in the serving cell, uses a PUCCH to transmit a periodic channel state information report in the serving cell, transmits, using the PUSCH, the periodic channel state information report during a subframe in which the PUSCH was scheduled, and does not transmit, using the sPUSCH, the periodic channel state information report during a subframe in which the sPUSCH was scheduled. According to this invention, the terminal device (1) can efficiently transmit uplink control information. Additionally, a base station device (3) can efficiently receive uplink control information.
