摘要： A terminal apparatus that communicates with a base station apparatus includes: a reception unit configured to receive a configuration of an initial uplink (UL) bandwidth part (BWP) and a configuration of an additional UL BWP via a radio resource control (RRC) message and receive a random access response (RAR) message including an RAR UL grant; and a transmission unit configured to transmit a physical uplink shared channel (PUSCH) in an active UL BWP, wherein one of the initial UL BWP and the additional UL BWP is activated as the active UL BWP, the PUSCH is scheduled by using the RAR UL grant, a first field included in the RAR UL grant is used to indicate frequency resource allocation of the PUSCH, and whether the first field is to be truncated or whether a bit is to be inserted into the first field is determined based on a bandwidth of the initial UL BWP.

摘要： A terminal apparatus and a base station apparatus communicate efficiently. A terminal apparatus includes: a reception unit configured to receive an RRC message including first configuration information and receive downlink control information including a first field by a physical downlink control channel; and a transmission unit configured to perform one or more repetitive transmissions of a physical uplink shared channel based on the first configuration information and the first field. The first configuration information is information for configuring at least a starting symbol of a time resource corresponding to an index indicated by the first field, a number of symbols allocated to one PUSCH corresponding to the index indicated by the first field, and a nominal number of repetitive transmissions corresponding to the index indicated by the first field.

摘要： A terminal apparatus receives an uplink grant used to schedule a PUSCH; transmits, in a case that an HARQ-ACK request included in the uplink grant is set so as to trigger transmission of an HARQ-ACK, the HARQ-ACK on the PUSCH corresponding to the uplink grant; and transmits, in a case that a CSI request included in the uplink grant is set so as to trigger a CSI report, an RI on the PUSCH corresponding to the uplink grant, in which an index of an SC-FDMA symbol in which the RI is transmitted is provided based on a value of the HARQ-ACK request.

摘要： Included are a receiver receiving a PDCCH and a PDSCH scheduled by the PDCCH, and a transmitter transmitting, on a PUCCH, one or multiple HARQ-ACKs including at least a HARQ-ACK corresponding to a TB included in the PDSCH and an SR.
For the HARQ-ACK of two or less bits, a resource of the PUCCH is, from one or multiple PUCCH resources in a PUCCH resource set, based at least on a first value based at least on the number of bits of the one or multiple HARQ-ACKs transmitted in the PUCCH, regardless of the number of resources of the SR overlapping with the PUCCH.
For the HARQ-ACK of more than two bits, the resource of the PUCCH is, from the one or multiple PUCCH resources in the PUCCH resource set, based at least on a sum of the number of bits of the one or multiple HARQ-ACKs and the SR.-

摘要： A terminal apparatus includes a receiver configured to receive a PDCCH including downlink control information used for scheduling of a PUSCH, a coding unit configured to encode uplink control information, and a transmitter configured to transmit the uplink control information by using the PUSCH. A coding rate R and a modulation order Q m are given based on one field included in the downlink control information. The number Q of coded bits of the uplink control information is given at least based on the number Q' of coded modulation symbols for the uplink control information and the modulation order Q m . The number Q' of coded modulation symbols is given at least based on the coding rate R and the modulation order Q m .

摘要： A terminal apparatus includes a receiver configured to receive a DCI format including an uplink grant, and a transmitter configured to transmit a PUSCH or an sPUSCH based on the uplink grant. A TTI of the PUSCH is one sub-frame. A TTI of the sPUSCH is shorter in value than one slot. In a case that a transmission of a channel quality indicator is triggered in response to a transmission of the PUSCH, the uplink control information is transmitted in the PUSCH. In a case that a transmission of a channel quality indicator is triggered in response to a transmission of the sPUSCH, a transmission of the uplink control information is dropped.

摘要： A terminal apparatus includes: a reception unit configured to: receive a PDCCH or an EPDCCH with a DCI format and a first RRC parameter, and decode a PDSCH according to detection of the PDCCH or the EPDCCH; and a transmission unit configured to: transmit a HARQ-ACK in a subframe n according to detection of the PDSCH in a subframe n-k. Whether the PUCCH resource is given at least based on the first RRC parameter is determined at least based on part of or all of the first condition and the second condition described below:
• first condition: the value k, and
• second condition: which one of CSS and USS is a search space to which a physical downlink control channel including the DCI format is mapped.-
