摘要： A terminal apparatus and a base station apparatus can perform communication efficiently. The terminal apparatus comprises a reception unit configured to: receive Downlink Control Information (DCI) that schedules a Transport Block (TB) on a first Physical Uplink Shared Channel (PUSCH); a control unit configured to: calculate Resource Elements (REs) based on a first number of symbols; and determine a transport block size of the TB for the first PUSCH based on at least the calculated REs; and a transmission unit configured to: transmit the TB on the first PUSCH with a second number of symbols. The first number of symbols is provided in a first field in the DCI, and the second number of symbols is based on the first number of symbols and a number of unavailable symbols.

摘要： An object of the present invention is to efficiently perform communication between a terminal apparatus and a base station apparatus. The present invention provides a terminal apparatus including: a receiver configured to receive an RRC message including information for indicating an RACH occasion corresponding to one of one or multiple CSI-RSs; and a transmitter configured to, in a case that a reference signal received power of at least one of the one or multiple CSI-RS blocks exceeds a prescribed threshold, select one of the one or multiple CSI-RS blocks with the reference signal received power exceeding the prescribed threshold, select the RACH occasion corresponding to the selected CSI-RS, and transmit a random access preamble in the selected RACH occasion.

摘要： Provided is a terminal device that receives RRC layer information indicating an asynchronous HARQ for a secondary cell, and a first random access response, which is a random access response including fields for indicating an uplink grant and a Temporary C-RNTI and is related to a non-contention based random access procedure on the secondary cell, that manages multiple HARQ processes, and that delivers the uplink grant to an HARQ process that instructs the transmission unit to transmit the MAC layer data in accordance with the uplink grant. In a case that the RRC layer information indicating the asynchronous HARQ is configured, a HARQ process in which the uplink grant included in the first random access response is delivered is determined based on the value of a field for indicating the Temporary C-RNTI included in the first random access response.

摘要： A terminal device is configured to activate and deactivate, on the basis of a MAC control element, a serving cell other than a primary cell, when a resource for a physical uplink control channel for a scheduling request used for requesting a UL-SCH resource for an initial transmission is not configured in the serving cell other than the primary cell. When the resource for the physical uplink control channel for the scheduling request is configured in the serving cell other than the primary cell, the serving cell other than the primary cell is always activated.

摘要： In a first case, in which a condition is satisfied that includes at least conditions that at least one scheduling request is pending in a certain TTI, there is no UL-SCH resource available for transmission in the certain TTI, and a terminal device has a valid resource for a physical uplink control channel for the scheduling request configured for the certain TTI, when a value of a counter is equal to a prescribed value or larger than the prescribed value, the terminal device initiates a random access procedure on a primary cell, releases a PUCCH resource for a scheduling request in a serving cell other than the primary cell, and cancels all pending scheduling requests.

摘要： With respect to uplink carrier aggregation, transmit power in a serving cell (c) is determined on the basis of maximum output power (PCMAXc c) for the serving cell c and total maximum output power (PCMAX). The maximum output power (PCMAX, c) for the serving cell (c) is based on maximum output power (PPowerClass) defined by a power class corresponding to a band to which the serving cell (c) belongs, and the total maximum output power (PCMAX) is based on maximum output power (PPowerClass) defined by a power class corresponding to a combination of aggregated bands.
