    摘要: Efficient downlink transmission is implemented. A terminal apparatus includes: a receiver configured to receive a sequence of bits in a physical downlink control channel, wherein the sequence of bits is scrambled with a scrambling sequence initialized by cinit, the cinit is given based at least on NID and NRNTI, the NID is given based at least on a higher layer parameter Control-scrambling-Identity in a case that the higher layer parameter Control-scrambling-Identity is configured and the NRNTI is given based at least on a Cell-Radio Network Temporary Identifier (C-RNTI), and the NID is given based at least on a physical layer cell identity in a case that the higher layer parameter Control-scrambling-Identity is configured and the NRNTI is not given based on the C-RNTI.

    摘要: A terminal apparatus is configured to: receive a transport block in a primary cell in a subframe i; in a case that HARQ-ACK and a positive scheduling request are transmitted, select a third transmission method in a case that a subframe j in a secondary cell does not correspond to any of first prescribed subframes, and select a fourth transmission method in a case that the subframe j corresponds to any of the first prescribed subframes; and transmit the HARQ-ACK in a PUCCH resource for a scheduling request, wherein the subframe j is given based on at least (I) whether or not a first parameter for the primary cell is configured, (II) whether or not a first parameter for the secondary cell is configured, and (III) a search space in which a PDCCH for scheduling the transport block is transmitted.

    摘要: A terminal apparatus includes: a receiver configured to receive first information related to query for capability of the terminal apparatus; and a transmitter configured to transmit second information related to the capability of the terminal apparatus, wherein the second information includes third information related to a band combination of operating bands used for carrier aggregation (CA), the band combination supported by the terminal apparatus, and in a case that more than one subcarrier spacings (SCSs) are supported by the terminal apparatus in each of the operating bands, the third information includes fourth information related to a SCS combination that can be applied to the band combination.

    摘要: A terminal apparatus capable of efficiently performing uplink and/or downlink communication is provided. Multiple CBs included in the transport block is decoded. HARQ-ACKs corresponding to multiple CBG are transmitted. The multiple CBs include one or more first CBs and one or more second CBs. A first size of a first CB of the one or more first CBs is greater than a second size of a second CB of the one or more second CBs. Each of the multiple CBs is included in any one of the multiple CBGs. The multiple CBGs include one or more first CBGs and one or more second CBGs. A first total number of the one or more first CBs and the one or more second CBs included in each of the one or more first CBGs is greater than a second total number of the one or more first CBs and the one or more second CBs included in each of the one or more second CBGs.

    摘要: A terminal apparatus includes a receiver configured to monitor a PDCCH in a control resource set and a transmitter configured to transmit a PUSCH scheduled based on an uplink grant included in a DCI format transmitted in the PDCCH. The PDCCH includes one or more Control Channel Elements (CCEs). One of the one or more CCEs includes six Resource Element Groups (REGs). One of the REGs includes a PRB in an OFDM symbol. The one CCE includes one or more REG bundles non-continuously mapped in a frequency domain. One of the one or more REG bundles includes one or a plurality of the REGs. The number of the REGs constituting the one REG bundle in the frequency domain is given per the number of OFDM symbols in the one CCE.
