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 stationincludes: a transmission unitwhich transmits an uplink signal; and a control unitwhich, 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.

Mobile station, base station, transmission method and receiving method

In the present invention, a mobile station is provided with: a control circuit that, on the basis of information that can specify the disposition of a first reference signal in a first system, determines the disposition of a second reference signal in a second system; and a receiving circuit that receives the second reference signal on the basis of the determined disposition.

Receiving device, transmitting device, receiving method, and transmitting method

The present invention provides a transmitter which can suitably perform a transmission power control in a PT-RS port. In this transmitter (), a control unit () determines a transmission power for transmitting a reference signal (PT-RS) for phase tracking and a data signal within a range in which the maximum transmission power for each antenna port is not exceeded. In addition, a transmission unit () transmits the reference signal for phase tracking and the data signal at the transmission power determined by the control unit ().

Transmitter and transmission method

In a transmitter, an assignment circuit maps a phase tracking reference signal (PT-RS) onto a subcarrier, and a transmitting circuit transmits a signal containing the phase tracking reference signal. The phase tracking reference signal is mapped onto a different subcarrier for each cell, group, or mobile station.

Transmitter, receiver, transmission method, and reception method

This mobile station is provided with a control circuit that, on the basis of information relating to a plurality of second time resources including a first time resource set to a first type of mobile station, decides a resource used for repeat transmission to a second type of mobile station, and a reception circuit that receives signals by a resource.

Mobile station, base station, reception method, and transmission method

Provided are a user equipment, base station and wireless communication methods related to uplink control information mapping in physical uplink resources in NR (New Radio access technology). A user equipment comprises: circuitry operative to map, in physical resource blocks (PRBs) for Physical Uplink Shared Channel (PUSCH), Uplink Control Information (UCI) to one or more available resource elements according to their distances with resource elements where reference signals are mapped in one or more of time domain, frequency domain and spatial domain; and a transmitter operative to transmit the UCI and the reference signals in PUSCH on the PRBs to a base station.

User equipment, base station and wireless communication method

Data communication can be appropriately performed in unlicensed bands. A mobile station () includes: reception circuitry, which, in operation, receives first information relating to a size configured for data, and second information relating to a resource to which the data is assigned; and control circuitry, which, in operation, controls reception of the data based on the first information and the second information.

Provided is a mobile station that can appropriately allocate resources in an unlicensed band. In the mobile station (), on the basis of resource association between an uplink reference signal and another uplink signal different from the reference signal, a control unit () determines a frequency resource to be used for uplink transmission. A transmission unit () uses the frequency resource to transmit at least one of the reference signal and the other uplink signal.

Mobile station, base station, transmission method and reception method

Transmitter, receiver, transmission method, and reception method with phase tracking reference signal mapping

An EVM measurement value is appropriately determined while CPE/ICI correction is taken into account. In a measurement apparatus (), an EVM measurer () measures a modulation quality of a signal transmitted from a transmission apparatus. An EVM determiner () determines whether or not the measurement value of the modulation quality is equal to or less than a first requirement value, in a case where correction relating to a phase noise of the transmission apparatus is necessary in a reception apparatus. The first requirement value herein is higher than a second requirement value used in the determination of the measurement value in a case where the correction relating to the phase noise of the transmission apparatus is unnecessary in the reception apparatus.

Measurement apparatus and measurement method

Provided is a base station with which it is possible to appropriately arrange a reference signal. In a base station (), a control unit () determines a second threshold value on the basis of a first threshold value used in determining the arrangement of a reference signal. A transmission unit () transmits the reference signal arranged on the basis of the second threshold value.
