摘要： A terminal according to one aspect of the present disclosure includes: a receiving section configured to receive, when a first physical cell ID (PCI) corresponding to a serving cell and a second PCI corresponding to a non-serving cell become active, information on a TCI state corresponding to each of the first and second PCIs; and a control section configured to control, based on the information on the TCI state corresponding to each of the first and second PCIs, reception of DL signals on assumption that the DL signals transmitted from the respective cells do not overlap each other in a time domain, or to control, when the DL signals transmitted from the respective cells overlap each other in the time domain, the reception of the DL signals based on a given rule.

摘要： A terminal according to one aspect of the present disclosure includes a control section that, when one or more control resource sets and a channel state information reference signal (CSI-RS) are configured to at least partially overlap each other in a time domain, determines quasi-co-location (QCL) assumption to be applied to the CSI-RS, based on a transmission configuration indication (TCI) state associated with a specific control resource set of the one or more control resource sets, and a receiving section that receives the CSI-RS to which the QCL assumption is applied. According to one aspect of the present disclosure, it is possible to appropriately determine a QCL of a specific reference signal.

摘要： A terminal according to one aspect of the present disclosure includes: a control section that determines one operation from a plurality of operations including a first operation of receiving a plurality of first reference signals among a plurality of reference signals and a second operation of receiving a plurality of second reference signals among the plurality of reference signals; and a receiving section that receives at least one of the plurality of first reference signals and the plurality of second reference signals, according to the one operation. The number of the plurality of second reference signals is smaller than the number of the plurality of first reference signals. According to one aspect of the present disclosure, coverage can be improved in consideration of overhead.

摘要： A terminal according to an aspect of the present disclosure includes: a receiving section that receives a plurality of downlink control information formats, each of the plurality of downlink control information formats including a transmission configuration indication (TCI) state indication; and a control section that applies a TCI state indicated by one downlink control information format of the plurality of downlink control information formats, at a specific timing after reception of the plurality of downlink control information formats. An aspect of the present disclosure allows a TCI state to be appropriately determined.

摘要： A terminal according to one aspect of the present disclosure includes a receiving section that receives a physical downlink control channel (PDCCH) for scheduling a physical downlink shared channel (PDSCH) to be repetitively transmitted, and a control section that, when a value of a period from reception of downlink control information (DCI) communicated on the PDCCH until reception of the PDSCH is greater than or equal to a threshold value, and the DCI does not include a transmission configuration indication (TCI) field, controls reception of the PDSCH to be repetitively transmitted, based on a TCI state of a specific control resource set associated with the PDCCH. According to one aspect of the present disclosure, it is possible to appropriately control operation related to a default TCI state / spatial relation / pathloss reference signal.
