Abstract: The present invention improves the reliability of a transmission channel. A transmission terminal according to the present invention is equipped with: a control circuit that, on the basis of a time resource quantity used to determine the transmission size of a first channel in one time segment of either a first time segment in which the first channel and a second channel are disposed or a second time segment in which the first channel is disposed, determines the transmission size in the other time segment; and a transmission circuit that, on the basis of the determined transmission size, performs a transmission process for the first channel in the first time segment and the second time segment.

Abstract: A communication apparatus includes a circuitry and a transmitter. In operation, the circuitry generates a Demodulation Reference Signal (DMRS) and generates downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the transmitter transmits the DMRS and the downlink control information. The plurality of mapping patterns include a first mapping pattern and a second mapping pattern. Resource elements used for the DMRS of the second mapping pattern are same as a part of resource elements used for the DMRS of the first mapping pattern. A number of the resource elements used for the DMRS of the first mapping pattern is larger than a number of the resource elements used for the DMRS of the second mapping pattern.

Abstract: Provided is a wireless communication device. A PHICH reception unit determines whether a received signal in a PHICH region is an ACK signal or a NACK signal. When doing so, the PHICH reception unit does not receive a PHICH in a subframe in which a terminal monitors an E-PDCCH. A control signal reception unit outputs a retransmission prompting signal to a signal allocation unit when the signal outputted from the PHICH reception unit is a NACK signal and when a UL grant was not detected. Meanwhile, when a UL grant was detected, the control signal reception unit outputs the detected UL grant to the signal allocation unit. The signal allocation unit maps the transmission signal in accordance with the retransmission prompting signal and the UL grant and transmits the transmission signal from a wireless transmission unit.

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: Provided are a UE, a scheduling node, and methods for a UE and for a scheduling node. The UE comprises circuitry which, in operation, monitors a first time or frequency resource for a first physical downlink control channel (PDCCH) on a first beam, and a transceiver which, in operation, receives a signal initiating switching from the first beam to a second beam, wherein the circuitry, in operation, at a timing of switching to the second beam, switches to a second time or frequency resource to be monitored for a second PDCCH on the second beam based on the signal and an indication of the second time or frequency resource, and wherein the first and the second PDCCHs are specific to the UE or to respective groups of UEs comprising the UE.

Abstract: The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.

Abstract: This invention is a transmission device capable of enhancing the reception characteristics of a terminal when employing transmit diversity using two antenna ports in an ePDCCH. In a base station (100) that transmits a reference signal to a terminal (200) using two antenna ports, a setting unit (102), on the basis of the reception quality of the terminal, sets as the aforementioned two antenna ports either a first antenna port pair for which DMRS (reference signals) do not undergo mutual code multiplexing, or a second antenna port pair for which the DMRS do undergo code multiplexing. A transmitter (109) transmits the DMRS from the two antenna ports set in the setting unit (102).
