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 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 base station selects, from among a plurality of code sequences orthogonal to one another, one code sequence by which an uplink signal including a demodulation reference signal repeated in a plurality of subframes is multiplied and transmits, to a terminal for which transmission of the repeated uplink signal is configured, information indicating the selected code sequence by using a field for indicating a cyclic shift and an orthogonal sequence used for the demodulation reference signal. A terminal receives information indicating one of a plurality of code sequences orthogonal to one another using a field for indicating a cyclic shift and an orthogonal sequence used for a demodulation reference signal and multiplies an uplink signal including the demodulation reference signal repeated in a plurality of subframes by the code sequence indicated by the information.

Abstract: A terminal with which it is possible to appropriately transmit uplink control information. In a terminal (200), a control unit (211) determines a processing format for a response signal or for an uplink control channel used for transmission of the response signal, in accordance with request conditions for a response signal of downlink data. A transmission unit (216) uses the uplink control channel to transmit the response signal on the basis of the determined processing format.

Abstract: A terminal includes a receiver, which, in operation, receives time unit information related to an amount of an uplink time resource per a time unit, and receives a number of repetitions over a plurality of the time units, wherein the time unit includes a downlink time resource for a downlink signal and the uplink time resource for a response signal. The amount of the uplink time resource is expressed as a fixed number of consecutive symbols that remains the same number over the plurality of the time units over which the response signal is repeatedly transmitted. The terminal includes a transmitter, which, in operation, repeatedly transmits the response signal over the plurality of the time units.

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: A repeater generates repetition signals by repeating an uplink signal over a plurality of subframes. If the plurality of subframes do not include a transmission candidate subframe of a sounding reference signal used to measure uplink reception quality, a controller sets a first transmission format to all the plurality of subframes, and if the plurality of subframes include the transmission candidate subframe, the controller sets a second transmission format to all the plurality of subframes. A transmitter transmits the repetition signals using the set transmission format.

Abstract: A base station (100, 300) is provided with a transmitter and a receiver. The transmitter (109) transmits a downlink signal in a downlink transmission region, in a time unit that includes the downlink transmission region, an uplink transmission region, and a gap period that is a switching point between the downlink transmission region and the uplink transmission region. The receiver (111) receives an uplink signal in the uplink transmission region, in the time unit. Furthermore, a delay tolerant signal for which a delay is tolerated more than for the downlink signal and the uplink signal is mapped to within the gap period.

Abstract: A wireless communication method includes receiving a reference signal and a data signal, based on a coverage enhancement level represented by a number of transmission repetitions; processing the reference signal and the data signal received by the receiving; setting a number of resource elements for transmitting the reference signal based at least on a channel type; and setting usage of resource elements indicated by a System Information Block (SIB). The reference signal is a Cell-specific Reference Signal (CRS) or a Demodulation Reference Signal (DMRS).
