摘要： A terminal according to one aspect of the present disclosure includes a control section that assumes that a time domain orthogonal cover code (TD-OCC) having a sequence length of a number greater than one is applied to a demodulation reference signal mapped to a pair of resource elements the number of which is greater than one and that are non-contiguous in time, and a transmitting/receiving section that performs transmission processing or reception processing of the demodulation reference signal, based on the TD-OCC. According to one aspect of the present disclosure, even when there are terminals according to different releases, each of the terminals can appropriately perform communication.

摘要： To appropriately control communication using at least one of a synchronization signal block and a reference signal even when communication is performed using a BWP, according to one aspect of the present disclosure, there is provided a user terminal including: a receiving section that receives at least one of a synchronization signal block and a given reference signal in a given bandwidth part (BWP); and a control section that decides whether to apply a synchronization signal block to a specific operation based on at least one of information regarding a frequency position of a synchronization signal block commonly reported by a serving cell and information regarding a frequency position of a synchronization signal block in the BWP.

摘要： A user terminal according to one aspect of the present disclosure includes: a transmitting section that transmits an uplink shared channel by applying a precoder; and a control section that specifies a number of ports used to determine the precoder when a Sounding Reference Signal (SRS) resource is not configured. According to one aspect of the present disclosure, even when an SRS resource is not configured, it is possible to appropriately determine a precoder of a UL signal.
