摘要： To provide a base station apparatus, a terminal apparatus, and a communication method capable of ensuring high reliability and low latency of URLLC. There are included a receiver configured to detect first and second DCI formats and RRC information, and a transmitter capable of data transmission based on any of a first uplink grant to be available via activation by using a radio resource periodicity included in the RRC information and the first DCI format, a second uplink grant to be available via activation by using the radio resource periodicity included in the RRC information and the second DCI format, and a third uplink grant to be available after detection of the second DCI format, wherein multiple DCI formats are detected, the transmitter performs an override, in a case that the third uplink grant overlaps in a time domain with the second uplink grant, and performs an override, in a case that the first uplink grant overlaps in a time domain with the third uplink grant.

摘要： A terminal apparatus includes a control information detection unit configured to detect first and second DCI, and a transmitter configured to perform UL data transmission based on the first DCI or cancel a resource allocated in the second DCI. A UL grant using the first DCI is detected, when performing UL data transmission based on the UL grant, after the data transmission, a first timer for a corresponding HARQ process is started and a second timer is stopped, and when the first timer expires, the second timer for a HARQ process is started. When cancellation of the UL data transmission using the second DCI is detected, at a timing for the data transmission canceled, the second timer is restarted in a case that the first timer expires and the second timer is running, and the second timer is started in a case that the second timer is not running.

摘要： A terminal apparatus includes a transmitter configured to transmit PUSCH data and a receiver configured to receive RRC information. The transmitter transmits the PUSCH data by using a resource associated with an HARQ process ID determined by symbol information for transmission of the PUSCH data, a period, and the number of HARQ processes. In a case that the receiver receives no response to the transmission of the PUSCH data with the HARQ process ID after the transmission of the PUSCH data is performed and before a timer included in the RRC information expires, the transmitter transmits new PUSCH data by using the resource associated with the HARQ process ID determined by the symbol information for the transmission of the PUSCH data, the period, and the number of HARQ processes.

摘要： A decrease in access rate to a wireless medium caused by an exposed terminal apparatus is improved. A wireless communication apparatus of the present invention includes a reception unit that receives a frame indicating start of a medium protection operation, and acquires, from the frame indicating the start of the medium protection operation, BSS identification information for identifying a BSS to which a transmission-source wireless communication apparatus of the frame indicating the start of the medium protection operation belongs, and a transmission unit that determines whether or not to start a transmission operation of a frame addressed to another wireless communication apparatus belonging to a BSS to which the wireless communication apparatus belongs based on the BSS identification information.

摘要： A terminal apparatus for communicating with a base station apparatus includes a transmission unit configured to transmit Phase-tracking reference signals (PTRS), and an higher layer processing unit configured to configure information for indicating a time density and/or a frequency density of the PTRS. A PTRS pattern is configured such that the time density of the PTRS is higher for a larger Modulation and Coding Scheme (MCS) scheduled for the terminal apparatus, and the frequency density of the PTRS is based on the number of resource blocks scheduled for the terminal apparatus.

摘要： In some embodiments, a communication apparatus can transmit OFDM signals that include at least a first period and a second period. The communication apparatus can include a transmitting section and a signal processing section. The transmitting section can transmit the OFDM signals to an additional communication apparatus by using multiple subcarriers allocated a set of two or more contiguous frequency channels. The contiguous frequency channels can be used simultaneously by the additional communication apparatus. The signal processing section is configured to not use at least all subcarriers positioned in the respective centers of these frequency channels when allocating data to the subcarriers in the frequency channels used to transmit the OFDM signals for a first period.
