Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/159299
Kind Code:
A1
Abstract:
The present invention appropriately transmits an uplink control channel in a future wireless communication system. This user terminal comprises: a reception unit that receives frequency hopping information indicating whether or not frequency hopping in an uplink control channel is enabled; and a control unit that applies at least one of a spread coefficient of a time-region orthogonal cover code, the configuration of a demodulation reference signal, and a standard sequence to the uplink control channel on the basis of the frequency hopping information.
