    Abstract: A terminal according to one aspect of the present invention includes a receiver and a processor. The receiver receives downlink control information that includes a resource assignment information of which a bit size is configured depending on a type of a signal. The processor determines a resource assignment based on the resource assignment information. A bit size of resource assignment information included in the downlink control information that schedules a downlink shared channel for transmitting system information is defined separately from a bit size of resource assignment information included in the downlink control information that schedules a downlink shared channel for transmitting user data. In other aspects, a radio communication method performed by a terminal, a base station, and a system are also disclosed.

    Abstract: A user terminal includes: a receiving section that monitors a physical downlink control channel for system information or paging in a connected mode; and a control section that determines a downlink reference signal that is quasi-co-location for the physical downlink control channel based on at least one of association between a physical downlink control channel monitoring occasion and a downlink reference signal and configuration information indicating a downlink reference signal that is quasi-co-location for a control resource set including the physical downlink control channel. According to an aspect of the present disclosure, a physical downlink control channel can be appropriately monitored.

    Abstract: A terminal is disclosed including a receiver that receives information including multiple spatial relation information; and a processor that controls transmission of channel state information using first spatial relation information that corresponds to a first transmission and reception point among the multiple spatial relation information, on a first repetition of multiple repetitions of an uplink shared channel, and controls transmission of the channel state information using second spatial relation information that corresponds to a second transmission and reception point among the multiple spatial relation information, on a second repetition of the multiple repetitions of the uplink shared channel. In other aspects, a communication method, a base station, and a system are also disclosed.
