Abstract: [Object] To provide a mechanism that enables flexible design in relation to communication timing.
[Solution] A communication apparatus including: a communication control unit that controls a transmission timing of a sub frame that is transmitted to another communication apparatus, which is a communication counterpart; and a setting unit that sets a control mode of the communication control unit to a first mode or a second mode. The communication control unit controls the transmission timing on the basis of a first parameter that is unique to the communication apparatus and a second parameter that is unique to the other communication apparatus in a case in which the first mode is set and controls the transmission timing on the basis of the second parameter in a case in which the second mode is set.-

Abstract: A communications device configured to receive data from an infrastructure equipment of a wireless communications network is provided. The communications device comprises transceiver circuitry configured to transmit signals and to receive signals via a wireless access interface provided by the wireless communications network, and controller circuitry. The controller circuitry is configured to control the transceiver circuitry to receive an explicit uplink hybrid automatic repeat request acknowledgement indicator, e-HARQ indicator, from the infrastructure equipment, and to determine, in accordance with the received e-HARQ indicator, whether or not the communications device should monitor for a first HARQ acknowledgement, HARQ-ACK, in a specific time slot and in a specific frequency resource of the wireless access interface, the first HARQ-ACK being transmitted by the infrastructure equipment in response to an uplink transmission from the communications device to the infrastructure equipment.

Abstract: [Overview][Problem to be Solved] To provide a communication apparatus that allows a coordinated operation to be executed between different operators.[Solution] There is provided a communication apparatus including a communication control unit that performs control to concurrently couple a base station of a first operator and a base station of a second operator wirelessly. A cell group of the base station of the first operator and a cell group of the base station of the second operator are different from each other. The communication control unit receives setting information regarding the base station of the second operator from the base station of the first operator.

Abstract: [Object] To provide a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other.[Solution] A terminal device that communicates with a base station device includes: a higher layer processing unit configured to set an STTI channel setting through signaling of a higher layer from the base station device; and a receiving unit configured to receive a first PDSCH in a case in which the STTI channel setting is not set and receive a second PDSCH in a case in which the STTI channel setting is set. The first PDCCH is mapped to one or more resource blocks, and the second PDCCH is mapped to one or more sub resource blocks defined in accordance with a smaller number of symbols than a number of symbols corresponding to a resource block.

Abstract: [Object] To provide a mechanism that enables flexible design in relation to communication timing.[Solution] A communication apparatus including: a communication control unit that controls transmission of any one of a first channel that is transmitted in a first direction and a second channel that is transmitted in a second direction that faces the first direction and corresponds to the first channel and reception of the other one of the first channel and the second channel; and a setting unit that sets a control mode of the communication control unit to a first mode or a second mode. The communication control unit transmits and receives the first channel and the second channel in different sub frames in the first mode and transmits and receives the first channel and the second channel in a same sub frame in the second mode.

Abstract: [Object] To provide a terminal device capable of efficiently performing communication in a communication system in which a base station device and the terminal device communicate with each other.[Solution] A terminal device that communicates with a base station device, including: a higher layer processing unit configured to perform SPDSCH setting through signaling of a higher layer from the base station device; and a receiving unit configured to receive a PDSCH in a case in which the SPDSCH setting is not performed and receive an SPDSCH in a case in which the SPDSCH setting is performed. The SPDSCH is mapped to any one of one or more SPDSCH candidates set on a basis of the SPDSCH setting. A number of symbols of a resource used for mapping of the SPDSCH is smaller than a number of symbols of a resource used for mapping of the PDSCH.
