Title:
USER TERMINAL, WIRELESS BASE STATION AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/021486
Kind Code:
A1
Abstract:
In order to appropriately carry out communication even when the transmission timing/transmission periods of a data channel and/or uplink control information are flexibly (variably) controlled, an embodiment of a user terminal of the present invention has a transmission unit which transmits uplink control information, and a control unit which controls the transmission of the uplink control information, which utilizes an uplink shared channel. The transmission timing and/or transmission periods of the uplink shared channel, and/or the transmission timing and/or transmission periods of the uplink control information, can be configured differently for each transmission. When using the uplink shared channel to transmit uplink control information, the control unit controls transmission of the uplink shared channel and the uplink control information on the assumption that the transmission timing and/or the transmission periods of the uplink shared channel and the uplink control information match.
