    Abstract: The objective of the present invention is to implement appropriate radio communication processing in accordance with required criteria. This terminal is provided with: a control circuit which determines a method for determining a priority level of a first channel and a second channel having mutually overlapping resource allocations in the time domain, on the basis of a parameter relating to control information indicating the allocations of the first channel and the second channel respectively; and a communication circuit for transmitting or receiving a signal to or from at least one of the first channel and the second channel, on the basis of the priority level.

    Abstract: In a base station (100), a controller (101) determines one set from among a plurality of sets, each of which including one or more candidates for a resource for an uplink (UL) control channel during initial access, and determines one candidate from among the one or more candidates for the resource, which is included in the determined set. A transmitter (114) indicates the determined set to a terminal (200) by higher layer signaling, and indicates the determined candidate by dynamic signaling. A receiver (116) receives a UL control signal, using the resource corresponding to the determined candidate in the determined set. In the base station, the association between a value to be indicated by the higher layer signaling and the plurality of sets is configured for each of one or more parameters relating to the initial access.

    Abstract: Provided are a user equipment, base station and wireless communication methods related to resource determination for UCI in case of BWP switching in NR. A user equipment comprises: a receiver operative to receive, from a base station in a slot, a Downlink Control Information (DCI) for Bandwidth Part (BWP) switching from a first BWP to a second BWP; circuitry operative to drop a Uplink Control Information (UCI) to be transmitted in a BWP switching period of the first BWP, and to determine the earliest available slot of the second BWP or a third BWP, the BWP switching period being from the slot where the DCI for BWP switching is received until starting the second BWP to which the first BWP is switched according to the DCI; and a transmitter operative to transmit the dropped UCI in the determined earliest available slot of the second BWP or the third BWP to the base station.

    Abstract: An object of this disclosure is to improve the channel estimation accuracy without degradation of transmission quality. Control section 101 configures a predefined number of demodulation reference signals (DMRSs) for terminal 200 configured to perform repetition of an uplink signal over multiple subframes, when a coverage enhancement level corresponding to the number of the multiple subframes is smaller than a determined value, and configures, for the terminal, a number of DMRSs obtained by adding a predetermined number of DMRSs to the predefined number, when the terminal applies the repetition and the coverage enhancement level is equal to or larger than the determined value, the uplink signal being formed by time-multiplexing a data symbol with a DMRS in one subframe. Receiving section 110 receives the uplink signal including the configured number of DMRSs and transmitted from the terminal. Channel estimation section 115 performs channel estimation using the DMRS included in the received uplink signal.
