摘要： A base station apparatus receives an uplink shared channel and a reference signal, the uplink shared channel including uplink data, an identifier of a terminal apparatus that has transmitted the uplink data, a first CRC generated from the identifier bits, and a second CRC generated from the uplink data bits. In a case that an error is detected based on the first CRC, the base station apparatus transmits a first NACK by using a control signal associated with the reference signal sequence. In a case that an error is detected based on the second CRC, the base station apparatus transmits a second NACK by using a control signal associated with the identifier indicating the terminal apparatus.

摘要： Provided are a base station apparatus, a terminal apparatus and a communication method, capable of an efficient retransmission control of uplink data of which a resource for transmission is not discerned in grant-free multiple access. A terminal apparatus configured to communicate with a base station apparatus includes a transmitter configured to transmit an identifying signal indicating that the terminal apparatus itself transmits an uplink data channel and the uplink data channel. The uplink data channel includes an uplink data bit, a bit representing an identifier of the terminal apparatus, a first error detection bit generated from the uplink data bit, and a second error detection bit generated from the identifier of the terminal apparatus. The first error detection bit is scrambled using the identifier of the terminal apparatus, and the second error detection bit is scrambled using the identifying signal.

摘要： In a case that a CQI table applied to interpret a CSI report is changed from a first CQI table including modulation schemes up to 64QAM to a second CQI table including modulation schemes up to 256QAM, information on a CQI table selection indicating applicability of the second CQI table and a CSI subframe set indicating subframes for which a CQI table selected in the CQI table is used are transmitted. In a case that the CQI table applied to interpret the CSI report is changed from the second CQI table to a third CQI table including modulation schemes up to 1024QAM, only the information on the CQI table selection indicating applicability of the third CQI table is transmitted.

摘要： In a case of a contention-based radio communication technique, it is necessary to identify a terminal apparatus that has performed data transmission among terminal apparatuses sharing frequency resources. There is a problem that it is difficult to identify the terminal apparatus that has performed data transmission in a case with a large number of terminal apparatuses that are non-orthogonally spatial multiplexed. Provided is a transmission device for transmitting a data signal to a reception device, the transmission device including: a transmission processing unit configured to transmit the data signal without performing SR transmission or receiving control information of transmission permission transmitted from the reception device; an identification signal multiplexing unit configured to multiplex an identification signal to an orthogonal resource; and a control information receiving unit configured to receive in advance a transmission parameter relating to transmission of the data signal. The transmission processing unit transmits the identification signal and a data signal in a case that the transmission processing unit repeatedly transmits the same data signal, based on the transmission parameter.
