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: 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 includes the steps of setting a standard sequence with a standard sequence length (Nb) and a standard sequence number (rb) in a step (ST101), setting a threshold value (Xth(m)) in accordance with an RB number (m) in a step (ST103), setting a sequence length (N) corresponding to RB number (m) in a step (ST104), judging whether |r/N−rb/Nb|=Xth(m) is satisfied in a step (ST106), including a plurality of Zadoff-Chu sequences with a sequence number (r) and a sequence length (N) in a sequence group (rb) in a step (ST107) if the judgment is positive, and allocating the sequence group (rb) to the same cell in a step (ST112).
Abstract translation: 本发明的目的是提供一种在保持Zadoff-Chu序列的数量以构成序列组的同时，使得可以减少不同顺序组之间的相关性的序列分配方法。 该方法包括以下步骤：在步骤（ST101）中设置标准序列长度（Nb）和标准序列号（rb）的标准序列，根据RB号设置阈值（Xth（m）） 在步骤（ST103）中，在步骤（ST104）中设定与RB号（m）对应的序列长度（N）的步骤（ST103），判断是否满足| r / N-rb / Nb | = Xth（m） 步骤（ST106），如果判断为肯定，则在步骤（ST107）中包括序列号（rb）中的序列号（r）和序列长度（N）的多个Zadoff-Chu序列，并且分配序列 组（rb）到步骤中的相同单元（ST112）。

Abstract: A terminal apparatus is disclosed wherein even in a case of applying SU-MIMO and MU-MIMO at the same time, the inter-sequence interference in a plurality of pilot signals used by the same terminal can be suppressed to a low value, while the inter-sequence interference in pilot signal between terminals can be reduced. In this terminal apparatus: a pilot information deciding unit decides, based on allocation control information, Walsh sequences of the respective ones of first and second stream groups at least one of which includes a plurality of streams; and a pilot signal generating unit forms a transport signal by using the decided Walsh sequences to spread the streams included in the first and second stream groups. During this, Walsh sequences orthogonal to each other are established in the first and second stream groups, and users are allocated on a stream group-by-stream group basis.

Abstract: The present disclosure provides a communication apparatus and a communication method for allocating one or more additional operating windows for a reception or a transmission of a sidelink signal. The communication apparatus comprises circuitry which, in operation, is configured to allocate one or more additional operating windows between a first operating window and a second operating window for a reception or a transmission of a sidelink signal, and a transceiver which, in operation, transmit or receive a sidelink signal within the one or more additional operating window.

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.

Abstract: Provided is a base station that performs feedback with regard to data transmission. The base station includes a downlink feedback information (DFI) generation unit and a transmitter. On the basis of a resource allocation configuration that was configured by a terminal, the DFI generation unit determines a transmission method for feedback information that includes a response signal regarding uplink data. The transmitter transmits the feedback information on the basis of the transmission method.

Abstract: According to the present invention, the received quality of a terminal is improved. The terminal comprises: a reception circuit (202) which receives information for providing a notification of the port of a reference signal for a downlink data signal; and a control circuit (208) which controls the reception of the downlink data signal and the reference signal, on the basis of a number of ranks less than the number of ports indicated by the received information.
