Abstract
A terminal apparatus includes a receiver configured to receive a first uplink grant used to indicate activation of a semi-persistent scheduling, a higher layer processing unit configured to store the first uplink grant as a configured uplink grant, and a transmitter configured to transmit a medium access control (MAC) protocol data unit corresponding to the configured uplink grant, wherein the higher layer processing unit does not generate the MAC protocol data unit in a case that the MAC protocol data unit includes only a MAC control element for a padding buffer status (BSR) report and aperiodic channel state information (CSI) is not requested.

1-12. (canceled)
A terminal device comprising:
- receiving circuitry configured to receive on a physical downlink control channel, information used for requesting a transmission of Channel State Information (CSI) on a physical uplink shared channel,
- transmitting circuitry configured to transmit a first Medium Access Control Protocol Data. Unit (MAC PDU) that includes a regular Buffer Status Report (BSR), and
- higher layer processing circuitry configured to determine not to generate a second MAC PDU that includes only a padding BSR in a case that the transmission of the CSI is not requested by using the information.
A base station apparatus comprising:
- transmitting circuitry configured to transmit on a physical downlink control channel, information used for requesting a transmission of Channel State Information (CSI) on a physical uplink shared channel,
- receiving circuitry configured to receive a first Medium Access Control Protocol Data. Unit (MAC PDU) that includes a regular Buffer Status Report (BSR), and higher layer processing circuitry configured to consider that a second MAC PDU that includes only a padding BSR is not generated in a case that the transmission of the CSI is not requested by using the information.
A communication method of a terminal device, comprising:
- receiving on a physical downlink control channel, information used for requesting a transmission of Channel State Information (CSI) on a physical uplink shared channel,
- transmitting a first Medium Access Control Protocol Data Unit (MAC PDU) that includes a regular Buffer Status Report (BSR), and
- determining not to generate a second MAC PDU that includes only a padding BSR in a case that, the transmission of the CSI is not requested by using the information.
A communication method of a base station apparatus, comprising:
- transmitting on a physical downlink control channel, information used for requesting a transmission of Channel State Information (CSI) on a physical uplink shared channel,
- receiving a first Medium Access Control Protocol Data Unit (MAC PDU) that includes a regular Buffer Status Report (BSR), and
- considering that a second MAC PDU that includes only a padding BSR is not generated in a case that the transmission of the CSI is not requested by using the information.
