Abstract:
A user terminal according to an aspect of the present disclosure includes: a transmitting section that transmits a measurement result of a reference signal measured by applying a spatial domain filter; and a control section that assumes, when having low latency beam selection configured by higher layer signaling and receiving confirmation information regarding the measurement result at time T, that a spatial domain filter of a given channel after a time when a second time has elapsed from the time T is the same as a spatial domain filter corresponding to the latest measurement result transmitted before a time going back by a first time from the time T. According to an aspect of the present disclosure, a TCI-state of a channel, QCL assumption, or a beam can be switched at high speed.
