Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/159343
Kind Code:
A1
Abstract:
In order to appropriately set a sequence to be applied to a reference signal and/or an uplink control channel, etc., in a future wireless communication system, one aspect of the user terminal according to the present disclosure is characterized by comprising: a transmission unit that transmits, by predetermined slots, a demodulation reference signal and/or an uplink control channel to which a predetermined sequence has been applied; and a control unit that selects, from among a plurality of predetermined sequences obtained for the slots at least on the basis of a frequency hopping index, a predetermined sequence to be applied when frequency hopping is set and/or a predetermined sequence to be applied when frequency hopping is not set.
