Abstract: A parameter required for an operation in a flexible bandwidth is appropriately determined. A base station (100) is disclosed in which: a controller (101) determines a parameter for a band composed of a first band and a segment that is an additional band for the first band, the band composed of the first band and the segment being referred to as a second band; and a transmitter (113) communicates with a terminal in the second band, using the parameter.

Abstract: The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit (103) sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit (108) places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit (103) causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.
Abstract translation: 本发明提供一种不会增加盲解码数量的基站，进一步防止资源分配的灵活性降低。 搜索空间设置单元（103）设置搜索空间，每个搜索空间由一个或多个控制信道单元（CCE）构成，并且其中每个控制信道单元被编码在终端中，并且每个由多个待定义的 代码候选人 分配单元（108）在包括在搜索空间中的多个待解码候选者之一中放置控制信道。 构成待解码候选的CCE的连接数与被解码候选的数量相关联。 搜索空间设置单元（103）根据要发送的控制信道，使构成待解码候选者的CCE的连接数与被解码的候选者的数量的关联不同。

Abstract: This terminal comprises: a reception circuit that receives control information corresponding to a downlink message in a random access procedure; and a control circuit that determines a setting for the repeated transmission of an uplink control signal for the downlink message, on the basis of a value of a field related to a setting different from the setting for the repeated transmission, in the control information.

Abstract: The present disclosure relates to a user equipment, UE, comprising the following. A processor determines a capability of the UE for operating a monitoring function, involving the following capability condition: —the capability condition regarding a minimum group time gap between two consecutive groups of time spans within a grouping window having a length of one or more slots. A transmitter transmits a capability indication to a base station, indicating the capability condition of the UE. A receiver receives, from the base station, information for configuring the monitoring function, including one or more monitoring occasions in which the UE monitors the downlink control channel.

Abstract: A repetition unit (212) performs a repetition for mapping a data signal and a demodulation reference signal (DMRS) repeatedly at a symbol level over a plurality of subframes. A signal allocation unit (213) maps, in the a plurality of subframes, the repeated DMRS to symbols other than symbols corresponding to an SRS resource candidate, which is a candidate for a resource to which a sounding reference signal (SRS) to be used to measure an uplink received signal quality is to be mapped. A transmission unit (216) transmits an uplink signal (PUSCH) including the DMRS and the data signal over the a plurality of subframes.

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: A terminal includes a receiver, which, in operation, receives time unit information related to an amount of an uplink time resource per a time unit, and receives a number of repetitions over a plurality of the time units, wherein the time unit includes a downlink time resource for a downlink signal and the uplink time resource for a response signal. The amount of the uplink time resource is expressed as a fixed number of consecutive symbols that remains the same number over the plurality of the time units over which the response signal is repeatedly transmitted. The terminal includes a transmitter, which, in operation, repeatedly transmits the response signal over the plurality of the time units.

Abstract: A communication device according to the present invention comprises a control circuit and a transmission circuit. The control circuit sets a transmission-enabled period in which information for adjusting resource usage between communication devices in sidelink communication can be transmitted, the transmission-enabled period being set on the basis of a processing time until another communication device stops or starts, in response to reception of the information, transmission of a sidelink data channel for which use by a sidelink control channel has been reserved. The transmission circuit transmits the information to the other communication device during the transmission-enabled period.
