Abstract: The present disclosure relates to a user equipment (UE) and a scheduling node, as well as to the corresponding methods. In particular, a downlink control information (DCI) signaling carries a Transmission Configuration Indication (TCI) indicator specifying that two or more TCI states are configured and a frequency-domain resource assignment indicating frequency-domain resources allocated for the two or more TCI states. For each TCI state of the two or more TCI states, one or more regions in frequency domain is/are determined, each region having an integer multiple of a precoding resource block group (PRG), said integer being equal to or larger than 1, wherein regions of different TCI states do not overlap. The data are received or transmitted for each TCI state on the frequency-domain resources in the determined frequency-domain region.

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: The present disclosure provides communication apparatuses and communication methods for optimising time domain window and demodulation reference signal (DMRS) for joint channel estimation. The communication apparatuses include a communication apparatus comprising: circuitry which, in operation, determines one or more time domain windows for multiple physical uplink shared channel (PUSCH) transmissions, each length of the one or more time domain windows being not more than an overall length of the multiple PUSCH transmissions; and a transmitter, which in operation, transmits reference signals based on the one or more time domain windows.

Abstract: It is an object to provide a sequence allocating method that, while maintaining the number of Zadoff-Chu sequences to compose a sequence group, is configured to make it possible to reduce correlations between different sequential groups. This method comprises the steps of setting a standard sequence with a standard sequence length and a standard sequence number in a step, setting a threshold value in accordance with an RB number in a step, setting a sequence length corresponding to RB number in a step, judging whether ¦r/N−rb/Nb¦=Xth(m) is satisfied in a step, including a plurality of Zadoff-Chu sequences with a sequence number and a sequence length in a sequence group in a step if the judgment is positive, and allocating the sequence group to the same cell in a step.

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).

Abstract: A terminal with which it is possible to appropriately transmit uplink control information. In a terminal (200), a reception unit (202) receives first control information relating to an uplink data channel, and a second control information relating to an uplink control channel for transmitting uplink control information. The first control information includes first indication information indicating the presence or absence of an uplink data transmission and second indication information indicating the presence or absence a channel state information transmission. A transmission unit (220) transmits uplink control information using the resource of the uplink data channel when the first indication information indicates that there is no uplink data transmission and the second indication information indicates that there is no channel state information transmission.
