Abstract: A terminal according to one aspect of the present disclosure includes: a receiving section that receives configuration information indicating whether or not to include an identifier of a panel related to a CSI report in the CSI report; and a transmitting section that transmits the CSI report including the identifier of the panel when the configuration information is received. According to one aspect of the present disclosure, a panel specific CSI report can be appropriately used.

Abstract: A terminal according to an aspect of the present disclosure includes: a receiving section that receives information indicating a spatial relation between a reference reference signal (RS) and an uplink (UL) target RS with respect to a UL transmission configuration indication (TCI) state; and a control section that controls to apply the TCI state to a UL channel and the UL target RS based on the information. According to the aspect of the present disclosure, appropriate UL transmission can be implemented.

Abstract: A terminal including a reception unit that receives configuration information in a high frequency band higher than or equal to a frequency band of a frequency range 2 (FR2), the FR2 being in a range including a frequency range 1 (FR1) that is a low frequency band and the FR2 that is a high frequency band in a new radio (NR) system; and a control unit that configures at least one of a format of a random access preamble, a sequence of the random access preamble, a subcarrier spacing applied to a channel on which the random access preamble is to be transmitted, or a subcarrier spacing applied to an uplink shared channel, based on the configuration information.

Abstract: A terminal according to an aspect of the present disclosure includes a receiving section that receives one piece of downlink control information (DCI) for scheduling a plurality of downlink shared channels (PDSCHs), and a control section that determines either a single TCI state or a plurality of TCI states for the plurality of PDSCHs in at least one of a first case and a second case, the first case being a case that a time offset from the DCI to the plurality of PDSCHs is shorter than a threshold, the second case being a case that a transmission configuration indication (TCI) field is not configured. According to an aspect of the present disclosure, QCL parameters for multi-panel/TRP can be appropriately determined.

Abstract: A terminal according to an aspect of the present disclosure includes: a control section that determines a plurality of pieces of channel state information (CSI) corresponding to at least one group and an ID corresponding to each of the plurality of pieces of CSI, each of the at least one group corresponding to at least one channel measurement; and a transmitting section that transmits each of the plurality of pieces of CSI in an occasion corresponding to the ID. With this configuration, reduction of reliability of CSI can be prevented while reducing increase of UL overhead.

Abstract: A terminal according to one aspect of the present disclosure includes a receiving section that receives a plurality of downlink shared channels (Physical Downlink Shared Channels (PDSCHs)) on the basis of one piece of downlink control information, and a control section that judges that a default transmission configuration indication state (TCI state) applied to the plurality of the PDSCHs corresponds to a TCI state corresponding to a code point in a TCI field for the downlink control information. According to one aspect of the present disclosure, it is possible to perform DL communication preferably even when multiple panels/TRPs are used.

Abstract: A terminal receives a radio frame having a second slot pattern to be used in a case in which a modulation system (FTN) different from a modulation system in a case of using a first slot pattern is applied. The terminal applies for the second slot pattern a configuration of an uplink and a downlink according to a time division duplex in the radio frame by using a reference subcarrier spacing same as that for the first slot pattern.
