Abstract: An EVM measurement value is appropriately determined while CPE/ICI correction is taken into account. In a measurement apparatus (300), an EVM measurer (305) measures a modulation quality of a signal transmitted from a transmission apparatus. An EVM determiner (306) 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.

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.

Abstract: The invention relates to an improved radio resource allocation performed by a vehicular mobile terminal. The vehicular mobile terminal determines whether to determine radio resources based on the location of the vehicular mobile terminal or not, based on information received from an entity of the communication system. In case the radio resources are to be selected based on the location of the vehicular mobile terminal, the vehicular mobile terminal determines the location of the vehicular mobile terminal, and determines radio resources for communication with at least the second mobile terminal, based on the determined location of the vehicular mobile terminal.

Abstract: A communication apparatus includes a receiver and circuitry. In operation, the receiver receives a Demodulation Reference Signal (DMRS) and receives downlink control information indicating a mapping pattern of the DMRS from a plurality of mapping patterns, and the circuitry determines the mapping pattern based on 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: The present disclosure relates to a user device, a base station, a method for data transmission/reception by a user device, and a method for data reception/transmission by a base station. The user device comprises circuitry which, in operation, receives a parameter defining a rule for assigning to ports respective resources for carrying reference signals, generates, based on a mapping known to the user device and the base station, a set of layer-to-port mapping combinations, and receives, from the base station, control information indicating one of the set of layer-to-port mapping combinations which is to be applied for data transmission and/or reception.
