摘要： A terminal apparatus of the present invention receives setting of an initial DL BWP by using an RRC message, the setting of the initial DL BWP comprises setting a first parameter and a second parameter of a CORESET #0, a value of an identifier of the CORESET #0 is 0, the first parameter represents the size of the CORESET #0, and the second parameter represents the size of the initial DL BWP. The terminal apparatus of the present invention receives a DCI format that schedules a PDSCH in an active DL BWP, and identifies, based on a field in the DCI format, a resource block set to which the PDSCH is allocated. A value of the field is determined based on the size of the DL BWP, the start resource block, and the number of consecutively allocated resource blocks. The size of the DCI format in a USS is determined based on the size of the CORESET #0, and when the field is applied to the active DL BWP, the size of the DL BWP is the size of the CORESET #0.

摘要： Provided is a terminal apparatus for communicating with a base station apparatus through a group including at least one or more cells. The terminal apparatus includes: a receiver configured to receive an RRC message from the base station apparatus; and a processing unit configured to perform processing of RRC. The processing unit causes, in a case that first information is included in the RRC message, a first timer to start to be in a running state, and considers, at least in a case that a random access problem indication is received from a MAC entity of the group in a state in which the first timer is not running, or in a case that a random access problem indication is received from a MAC entity of the group in a state in which the first timer is running under a specific condition, a radio link failure for the group to be detected. In a case that the radio link failure for the group is considered to be detected and that the first timer is running under the specific condition, the processing unit suspends transmission of all of radio bearers in the group, and resets the MAC entity of the group.

摘要： A terminal apparatus and a base station apparatus efficiently communicate with each other. A terminal apparatus receives a first DCI and determines transmission of a first PUSCH. The first PUSCH is scheduled by the first DCI, a value of a first PUSCH procedure preparation time for the first PUSCH is a first value in a case that a first condition is not satisfied, and the value of the first PUSCH procedure preparation time is a value acquired by adding a second value to the first value in a case that the first condition is satisfied. The terminal apparatus determines the transmission of the first PUSCH in a case that a number of symbols between the first DCI and the first PUSCH is equal to or greater than a number of symbols corresponding to the value of the first PUSCH procedure preparation time.

摘要： A terminal apparatus includes: a reception unit which receives, from a base station apparatus, a physical downlink control channel including downlink control information in a search space specific to the terminal apparatus; and a control unit which determines the number of bits of a time domain resource allocation field in the downlink control information. The time domain resource allocation field is a time domain resource allocation field for a physical downlink shared channel A default table indicates a time domain resource allocation configuration for the physical downlink shared channel. When a parameter is not received, the number of bits of the time domain resource allocation field is determined based on the number of the in the default table.
