摘要： In a terminal, based on a first parameter included in each of a plurality of downlink control signals, the first parameter indicating a cumulative count of code block groups (CBGs) configuring each of a plurality of transport blocks (TBs) assigned by the plurality of downlink control signals, a HARQ-ACK generation unit generates a response signal (HARQ-ACK) for each of the code block groups. A transmission unit collectively transmits the response signals for each of the code block groups.

摘要： Provided are a user equipment, base station and wireless communication methods related to multiplexing of UCI in PUSCH in NR. A user equipment comprises: circuitry operative to process UCI bits to be transmitted according to the comparison of the number M of UCI bits generated based on DL assignment(s) before an UL grant from a base station and the number N of UCI bits generated based on DL assignment(s) after the UL grant with the number P of UCI bits indicated in the UL grant and/or the maximum number Q of bits determined based on at least a configured coding rate, wherein each of M, N, P, Q is an integer equal to or larger than 0; and a transmitter operative to transmit the processed UCI bits in PUSCH at a TTI indicated in the UL grant to the base station.

摘要： A wireless station that belongs to a communication cell includes a receiver which, in operation, receives a trigger frame transmitted from an access point that belongs to an interference cell and a controller which, in operation, determines, based on at least one parameter included in the trigger frame and reception power value of the trigger frame received at the wireless station, whether the wireless station is allowed to transmit to other wireless station that belongs to the communication cell, wherein the at least one parameter includes a value set based on transmit power value of the trigger frame transmitted from the access point.

摘要： According to the present invention, a base station can dynamically change a repetition transmission method as appropriate. In a base station (100), a repetition control unit (103) determines a data repetition pattern for a terminal (200). A transmission unit (109) repeatedly transmits data (repetition transmission) on the basis of the repetition pattern. The data repetition pattern corresponds to control information to be reported to the terminal (200) by dynamic signaling.

摘要： Provided is a terminal which can suitably apply precoding to a PDCCH. In the terminal (100), when a first CC is notified of scheduling information for each of a first component carrier (CC) and a second CC, a restriction determination unit (105) determines, on the basis of a subcarrier interval of the CC to be scheduled by means of the scheduling information among the first CC and the second CC, the maximum number of blind decodings when the scheduling information is blind-decoded. An extraction unit (102) performs the blind decoding on the basis of the maximum number of blind decodings and extracts the scheduling information.

摘要： Provided is a base station capable of appropriately applying precoding to a PDCCH. At the base station (100), a precoding control unit (105) sets a precoding granularity, which indicates a period in which the same precoding is used, to multiple control channels respectively disposed in different time resources. A transmission unit (108) transmits signals of the multiple control channels to a terminal (200) on the basis of the set precoding granularity.

摘要： Provided is a base station capable of enhancing signal reception performance. In the base station (100), a control unit (101) generates data signals in unit of fixed length. A transmission unit (107) performs repetitive transmission of a transmission signal including at least one of the data signals in unit of fixed length in a resource that can be set to a plurality of data lengths.
