Abstract

To suppress deterioration of performance due to a collision between signals, a user terminal according to one aspect of the present invention includes a transmitting/receiving section that performs transmission or reception of a data demodulation reference signal and a specified signal different from the data demodulation reference signal, and a control section that controls a change of a first resource and/or a second resource based on notification information from a network, when at least a part of the first resource configured for the data demodulation reference signal overlaps with at least a part of the second resource configured for the specified signal.
