Abstract: The disclosure relates to a user equipment (UE). The UE comprises a transceiver and a circuitry. The transceiver, in operation, receives downlink control information (DCI) signaling; and control information. The circuitry, in operation, obtains, from the DCI signaling, an indication indicating, for each of a plurality of transport blocks (TBs), scheduling of one or more transmissions of said TB. The circuitry, in operation, obtains, from the control information, a cancellation indication (CI) indicating a resource. Furthermore, the circuitry, in operation, determines, based on the indicated resource and a predetermined rule, which of the scheduled transmissions of the plurality of TBs are cancelled.

Abstract: According to the present invention, a base station can dynamically change a repetition transmission method as appropriate. In a base station (100), a repetition control unit (103) determines a data repetition pattern for a terminal (200). A transmission unit (109) repeatedly transmits data (repetition transmission) on the basis of the repetition pattern. The data repetition pattern corresponds to control information to be reported to the terminal (200) by dynamic signaling.

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: At a base station, a control unit selects one combination from multiple combinations of parameters regarding uplink control channel (PUCCH) resources. A transmission unit indicates a terminal of resource settings (Semi-static resource configuration) including the multiple combinations by higher layer signaling, and indicates the terminal of the one combination that has been selected by dynamic signaling (DCI).

Abstract: A communication apparatus includes circuitry that determines a number of resource blocks forming a resource block group, which is a unit used to allocate a resource to the communication apparatus, in a first band or in a second band that is an expanded band to which the first band is expanded, and a subcarrier spacing for the second band is same or different from a subcarrier spacing for the first band; and a transceiver that is coupled to the circuitry and that communicates with a base station using the resource. One of the number of resource blocks set for the first band and the number of resource blocks set for the second band is an integer multiple of the other, and the number of resource blocks set for the first band and the number of resource blocks set for the second band are values that are a power of two.

Abstract: In an operation in a license-exempt band (unlicensed band), the present invention contributes to the provision of a mobile station, a base station, a transmission method and a receiving method which suitably transmit and receive a signal. The mobile station 200 includes: a transmission unit 205 which transmits an uplink signal; and a control unit 201 which, when a first number indicating a first resource amount that can be used in the transmission of the uplink signal includes a third number, which is different from a specific second number, as a prime factor, controls the transmission of a signal of a fourth number that does not include the third number as the prime factor by using a second resource.

Abstract: A parameter required for an operation in a flexible bandwidth is appropriately determined. A base station (100) is disclosed in which: a controller (101) determines a parameter for a band composed of a first band and a segment that is an additional band for the first band, the band composed of the first band and the segment being referred to as a second band; and a transmitter (113) communicates with a terminal in the second band, using the parameter.
