摘要： A terminal apparatus and a base station apparatus efficiently communicate. A terminal apparatus including a receiver configured to receive an RRC message including first configuration information and to receive DCI on a PDCCH, a determination unit configured to determine a time parameter for transmitting a PUSCH, based on a bit sequence indicated by a first field of the DCI, and a transmitter configured to transmit the PUSCH, based on the time parameter. A relationship between the bit sequence and the time parameter is defined by a first parameter group in a case that a first condition is satisfied and that the first configuration information includes the first parameter group and the relationship between the bit sequence and defined by a second parameter group in a case that a second condition is satisfied and that the first configuration information includes the second parameter group.

摘要： A terminal apparatus includes a receiver and a transmitter. The receiver is configured to receive a radio resource control (RRC) parameter and a physical downlink control channel (PDCCH) including a downlink control information (DCI) format and scheduling a physical uplink shared channel (PUSCH). The transmitter is configured to transmit the PUSCH with frequency hopping within one slot. The RRC parameter indicates one or a plurality of frequency offset values. The PUSCH includes a first frequency hop and a second frequency hop within the one slot. In a case that a cyclic redundancy check (CRC) scrambled with or other than a temporary cell-radio network temporary identifier (TC-RNTI) is added to the DCI format, a frequency offset between the first frequency hop and the second frequency hop is based on a size of an initial uplink (UL) bandwidth part (BWP) or the RRC parameter, respectively.

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.
