Title:
USER TERMINAL AND RADIO COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/021487
Kind Code:
A1
Abstract:
In order to appropriately carry out communication even when the transmission timing/transmission periods of the data channel and/or uplink control information are flexibly (variably) controlled, one embodiment of this user terminal has a transmission unit which transmits uplink control information, and a control unit which controls transmission of uplink control information over 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; in the case of at least partial overlap between the transmission period of the uplink shared channel and the transmission period of the uplink control information, the control unit transmits the uplink control information over the shared uplink channel.
