Title:
USER TERMINAL AND WIRELESS COMMUNICATIONS METHOD
Document Type and Number:
WIPO Patent Application WO/2018/143394
Kind Code:
A1
Abstract:
In order to appropriately notify uplink control information, even when using a sequence-based uplink control channel, this user terminal has: a control unit that determines a signal to be sent using a frequency resource for sending uplink control information; and a transmission unit that sends the signal using the frequency resource. The control unit is characterized by assuming that the frequency resource bandwidth is at least a prescribed bandwidth, if the signal includes a signal sequence having applied thereto an orthogonal resource associated to the uplink control information.
