Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/159300
Kind Code:
A1
Abstract:
According to the present invention, an uplink control channel is appropriately transmitted 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 one slot of an uplink control channel is enabled, and receives information indicating the number of slots of the uplink control channel; and a control unit that, when the number of slots is greater than 1, applies, on the basis of the frequency hopping information, 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, and controls repeated transmission of the uplink control channel over the number of slots.
