摘要： Provided is a transmitter configured to transmit a PUCCH by applying a transmission filter based on any one piece of spatial relation information of a spatial relation information set, and transmit a PUSCH in a slot set by applying multiple transmission filters respectively based on multiple pieces of spatial relation information included in a spatial relation information subset of the spatial relation information set. The spatial relation information subset at least includes first spatial relation information and second spatial relation information different from the first spatial relation information. The transmitter applies a transmission filter of the multiple transmission filters based on the first spatial relation information to the PUSCH of a first slot subset of the slot set. The transmitter applies a transmission filter of the multiple transmission filters based on the second spatial relation information to the PUSCH of a second slot subset of the slot set.

摘要： A terminal apparatus includes a reception circuitry configured to receive a DCI format used for scheduling of a PUSCH, and a transmission circuitry configured to transmit the PUSCH in multiple slots. A size of a transport block is given based on a target coding rate indicated by the DCI format. The target coding rate is 1 or greater. An effective coding rate of the PUSCH is 1 or less. The effective coding rate is a value obtained by dividing the size of the transport block by a product of a modulation order of the PUSCH and the number of resource elements of the PUSCH.

摘要： Terminal device receives a high-layer parameter and transmits a PRACH. The high-layer parameter indicates a set of PRACH occasions and a PRACH slot for transmission of the PRACH. In a case that a PRACH occasion in the set of PRACH occasions is allocated to a slot different from the PRACH slot, the PRACH occasion is dropped for transmission of the PRACH.

摘要： A terminal apparatus comprises a reception unit and a higher layer processing unit. When a carrier is set in an unlicensed band, the reception unit is configured to detect a first PDCCH in a first type 0 PDCCH common search space set and receive a first PDSCH scheduled by the first PDCCH. When the carrier is not set in the unlicensed band, the reception unit is configured to detect a second PDCCH in a second type 0 PDCCH common search space set and receive a second PDSCH scheduled by the second PDCCH. A higher layer processing unit is configured to manage common RRC signaling included in the first PDSCH or the second PDSCH. A time domain resource configuration of the first PDSCH is a first configuration, and a time domain resource configuration of the second PDSCH is a second configuration different from the first configuration.

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 technology related to a terminal apparatus, a communication method, and an integrated circuit is provided for efficiently monitoring a status of communication. The terminal apparatus communicates with a base station apparatus by switching between a first frequency and a second frequency in the cell, in which any one of the first frequency and the second frequency is a frequency by which the terminal apparatus has established Radio Resource Control (RRC) connection, and a timer stops or continues based on first information in the case of switching between the first frequency and the second frequency.

摘要： To provide a terminal apparatus, a base station apparatus, and a communication method that enable a communication apparatus (terminal apparatus and/or base station apparatus) supporting multiple subcarrier spacings to perform efficient communication. A terminal apparatus includes: a control unit configured to identify a subcarrier spacing set applicable to a data channel, based on a first parameter included in higher layer signaling; and a reception unit configured to receive a control channel including data channel assignment information. Based on a type of the data channel assignment information, the terminal apparatus selects, from the subcarrier spacing set, a subcarrier spacing applicable to the data channel assigned based on the data channel assignment information.

摘要： Uplink data is transmitted efficiently. Provided is a terminal apparatus including a receiver configured to receive a first UL grant, a second UL grant and a random access response grant, and a transmitter configured to perform transmission on a PUSCH. In a case that the transmission on the PUSCH corresponds to the second UL grant to which a CRC parity bit scrambled by a C-RNTI is attached, first transmission is performed on the PUSCH at a transmission time interval of a length indicated using the second UL grant. In a case that the transmission on the PUSCH corresponds to a random access response grant, second transmission on the PUSCH is performed at a transmission time interval of a length of 1 ms.
