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, the second PDCCH is mapped to one or more sub resource blocks, and the second PDSCH is demodulated using a reference signal mapped to a symbol including the sub resource block or a resource element before the symbol.

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 perform one or more second PDCCH settings through signaling of a higher layer from the base station device; a receiving unit configured to monitor only a common search space and a terminal device-specific search space in a first PDCCH in a case in which the second PDCCH setting is not performed, and monitor a terminal device-specific search space in at least a second PDCCH in a case in which the second PDCCH setting is performed. The first PDCCH is transmitted on a basis of a sub frame defined in accordance with a predetermined number of symbols. The second PDCCH is transmitted on a basis of an extended sub frame of a smaller number of symbols than a number of symbols corresponding to the sub frame, and a resource block set through the second PDCCH setting.

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 perform SPDSCH setting through signaling of a higher layer from the base station device; a receiving unit configured to perform a reception process on all of one or more SPDSCH candidates set on a basis of the SPDSCH setting, and receive an SPDSCH; and a transmitting unit configured to use a resource set on the basis of the SPDSCH setting to report response information for the SPDSCH. In a case in which the SPDSCH is correctly received, the response information is reported, and in a case in which the SPDSCH is not correctly received, the response information is not reported.

Abstract: A communications device receive data from a wireless communications network by detecting from one or more control channels of a wireless access interface one or more encoded data units of a plurality of encoded data units into which an error correction encoded control information has been divided in accordance with an incremental redundancy scheme. The communications device decodes the error correction encoded control information by combining the one or more detected encoded data units in accordance with an arrangement of encoded bits of the error correction encoded control information in each of the plurality of encoded data units. Each of the plurality of encoded data units comprises a different set of the encoded bits according to a different redundancy version number of the incremental redundancy scheme.

Abstract: A method of controlling communications within a wireless communications network is provided. The method comprises receiving, at a first infrastructure equipment acting as a donor node connected to a core network part of a wireless communications network, signals representing data from one or more others of infrastructure equipment, the data having been received at the one or more others of the infrastructure equipment from one or more communications devices or from other infrastructure equipment, and transmitting, by the first infrastructure equipment, the data from the one or more others of the infrastructure equipment to the core network part of the wireless communications network. At least one of the infrastructure equipment uses at least one spectral efficiency enhancing technique to receive the signals, the at least one spectral efficiency enhancing technique allowing the at least one infrastructure equipment to receive the signals in the backhaul communications link.
