Abstract: A user apparatus includes, a control unit configured to apply in a specific order a plurality of processing rules for determining a channel as a transmission candidate by dropping a channel or multiplexing channels and repeat the application until detecting no channel collision in a time domain, in a case where a channel associated with a first service type and a channel associated with a second service type collide with each other at least in a time domain, and for at least one of the channel associated with the first service type and the channel associated with the second service type, a plurality of channels associated with a same service type collide with each other at least in the time domain; and a transmitting unit configured to transmit, to a base station apparatus, the channel as the transmission candidate for which no channel collision is detected in the time domain.

Abstract: A terminal is disclosed including a receiver that receives downlink control information that triggers channel state information (CSI) reporting using an uplink shared channel; and a processor that controls the CSI reporting based on a given value and transmission timing of at least one of the uplink shared channel and a delivery acknowledgement signal (HARQ-ACK). In other aspects, a radio communication method for a user terminal is also disclosed.

Abstract: The present invention is designed so that UCI can be transmitted properly even when a PUSCH of a long TTI and an sPUSCH of a short TTI collide with each other in a same carrier. According to the present invention, a user terminal has a transmission section that transmits UCI, and a control section that controls re-direction of at least part of the UCI, when a PUSCH of a long TTI carrying the UCI, and an sPUSCH of a short TTI, collide with each other in a same carrier.

Abstract: A user terminal according to one aspect of the present disclosure includes: a control section that determines a maximum number of downlink control channel (physical downlink control channel (PDCCH)) candidates monitored for first subcarrier spacing (SCS) and a maximum number of non-overlapped control channel elements (CCEs) based on a number of downlink cells scheduled by a carrier corresponding to the first SCS when cross-carrier scheduling from a carrier corresponding to the first SCS to second SCS is configured; and a receiving section that monitors the PDCCH candidates in a carrier corresponding to the first SCS based on the maximum number of the PDCCH candidates and the maximum number of the non-overlapped CCEs. According to one aspect of the present disclosure, a downlink control channel can be appropriately monitored even when cross-carrier scheduling over different numerologies is introduced.

Abstract: A user terminal includes a receiving section that receives, in a first cell, first downlink control information indicating that configuration of configured grant type 2 or downlink Semi-Persistent Scheduling (DL SPS) of a second cell or a specific Bandwidth Part (BWP) is to be activated, and receives second downlink control information, and a control section that considers that the configuration is to be deactivated, based on a value of a specific field in the second downlink control information. According to an aspect of the present disclosure, configured grant or DL SPS can be appropriately controlled by using downlink control information.

Abstract: A user terminal according to one aspect of the present disclosure includes a control section that determines, for a given control resource set (CORESET), a quasi-co-location (QCL) property of a demodulation reference signal (DMRS) for a physical downlink control channel (PDCCH), based on an active transmission configuration indication (TCI) state corresponding to a plurality of reference signals, and a receiving section that receives the PDCCH based on the QCL property. According to one aspect of the present disclosure, beam relevant control can be appropriately performed.
