Title:
USER TERMINAL AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/053901
Kind Code:
A1
Abstract:
A user terminal according to an embodiment of the invention comprises: a transmission unit that transmits, by frequency-division multiplexing with uplink control information, a reference signal generated on the basis of a base sequence; and a control unit that controls, on the basis of the sequence length of the base sequence, switching between a first sequence and a second sequence to be used for generating the base sequence. Thus, it is possible to appropriately transmit the reference signal that is frequency-division multiplexed with the uplink control information.
