    摘要： To appropriately perform communications even when a random access procedure with less steps than existing steps is performed, an aspect of a user terminal according to the present disclosure includes a transmitting section that transmits a UL signal including a random access preamble and a certain message, a receiving section that receives a DL signal transmitted in response to the UL signal, and a control section that controls at least one of transmission of the UL signal and reception of the DL signal by applying a common behavior to a first procedure for transmitting the UL signal in accordance with an indication from a network and a second procedure for transmitting the UL signal without any indication from the network.

    摘要： To properly control UL transmissions of A/N in response to a plurality of DL transmissions with different requirements and the like, one aspect of a user terminal in the present disclosure has a transmitting section that transmits a first delivery acknowledgement signal (A/N) in response to a first PDSCH and a second A/N in response to a second PDSCH transmitted later than the first PDSCH, and a control section that controls to transmit at least one of the first A/N and the second A/N, using one of an uplink control channel configured for the first A/N and another uplink control channel configured for the second A/N, in a case where transmission timing of the first A/N overlaps transmission timing of the second A/N.

    摘要： To appropriately control half-duplex communication in a future radio communication system, one aspect of a user terminal according to the present disclosure includes: a reception section that receives slot format information that indicates a slot format of a cell; and a control section, when transmission and reception in transmission directions are instructed, performs control to perform transmission and reception in a given cell and to not perform transmission and reception in another cell based on a method for instructing transmission and reception in each cell, the transmission directions being different between a plurality of cells for which slot formats are configured to flexible.

    摘要： To appropriately perform communications even when a random access procedure with less steps than existing steps is performed, an aspect of a user terminal according to the present disclosure includes a transmitting section that transmits a UL signal including a random access preamble and a certain message, a receiving section that receives a DL signal transmitted in response to the UL signal, and a control section that determines whether to retransmit the UL signal, based on at least one of a period since reception of the DL signal, an indication content of the DL signal, and a content of a bit field configured for a downlink control channel included in the DL signal.

    摘要： A user terminal according to one aspect of the present disclosure includes: a transmitting/receiving section that receives or transmits a shared channel based on fallback Downlink Control Information (DCI); and a control section that makes a given assumption on a density of a Phase Tracking Reference Signal (PTRS) of the shared channel scheduled by the fallback DCI. According to one aspect of the present disclosure, it is possible to appropriately determine a PTRS density.
