Abstract: Provided is a terminal that makes it possible to improve the efficiency of random access processing. A control unit (209) in the terminal (200) uses channel quality as a basis to select either a first method for transmitting a random access signal including a preamble section and a data section or a second method for transmitting a random access signal that includes a preamble section and that does not include a data section. A transmission unit (217) transmits a random access signal on the basis of the selected method.

Abstract: A user equipment, a base station and respective methods are provided. The user equipment receives a physical uplink shared channel (PUSCH) config information element (IE) in form of radio resource control (RRC) signaling, the PUSCH config IE being applicable to a particular bandwidth part. The user equipment configures a table which is defined by a PUSCH time domain resource allocation list IE carried in the received PUSCH config IE, the table comprising rows, at least one row comprising a first set of values related to allocated time-domain resources for a plurality of PUSCH transmissions. The user equipment receives downlink control information (DCI) signaling carrying a time-domain resource assignment filed with value m, wherein the value m provides a row index m+1 to the RRC configured table. The user equipment determines allocated time-domain resources for the plurality of PUSCH transmissions based on the index of the slot carrying the received DCI.

Abstract: Provided is a terminal that can appropriately transmit an uplink signal. In a terminal (200), a control unit (211) determines a processing mode with respect to uplink data and uplink control information according to a requirement for at least one of uplink data and uplink control information when transmission of an uplink data channel that includes the uplink data and transmission of an uplink control channel that includes the uplink control information temporally overlap. A transmission unit (218) transmits the at least one of the uplink data and the uplink control information on the basis of the determined processing mode.

Abstract: In a terminal (200), a radio transmitter (209) transmits a signal, and a controller (204) determines an allocation resource to which a signal is assigned in a predetermined frequency band. The predetermined frequency band herein is divided into a plurality of bands, and each of the plurality of bands includes a plurality of frequency resources which are base units of resource allocation for the signal. Furthermore, the allocation resource to which the signal is assigned is composed of at least one of the base units of each of the plurality of bands. Furthermore, a configuration method of the at least one of the base units forming the allocation resource is different for each of the plurality of bands.
