Mobile station device, radio communication method and integrated circuit
A mobile station device transmits a transport block in an uplink subframe. The mobile station device delivers acknowledgement (ACK) for the transport block to higher layers in a case that the transport block was transmitted by the mobile station device to a base station device and the transport block is disabled based on a physical downlink control channel received in a downlink subframe.
1. A mobile station device comprising:
reception circuitry configured to, programmed to, or configured and programmed to receive one or more downlink control information (DCI) including at least one of
a first DCI indicating that transmission of first uplink data is not disabled and transmission of second uplink data is disabled, and
a second DCI indicating retransmission of the second uplink data; and
transmission circuitry configured to, programmed to, or configured and programmed to, based on the one or more DCI, transmit at least one of the first uplink data and the second uplink data on a physical uplink shared channel,
wherein the transmission circuitry is configured to, programmed to, or configured and programmed to,
in a first case that the first DCI is received
transmit the first uplink data without transmitting the second uplink data, and
keep the second uplink data in a buffer, and
in a second case that the second DCI is received after the first DCI is received,
transmit the second uplink data.
2. A communication method for a mobile station device, comprising:
receiving one or more downlink control information (DCI) including at least one of
a first DCI indicating that transmission of first uplink data is not disabled and transmission of second uplink data is disabled, and
a second DCI indicating retransmission of the second uplink data; and
transmitting, based on the one or more DCI, at least one of the first uplink data and the second uplink data on a physical uplink shared channel, wherein
in a first case that the first DCI is received,
transmitting the first uplink data without transmitting the second uplink data, and
keeping the second uplink data in a buffer, and
in a second case that the second DCI is received after the first DCI is received,
transmitting the second uplink data.
3. An integrated circuit mountable on a mobile station device, the integrated circuit comprising:
reception circuitry configured to, programmed to, or configured and programmed to receive one or more downlink control information (DCI) including at least one of
a first DCI indicating that transmission of first uplink data is not disabled and transmission of second uplink data is disabled, and
a second DCI indicating retransmission of the second uplink data; and
transmission circuitry configured to, programmed to, or configured and programmed to, based on the one or more DCI, transmit at least one of the first uplink data and the second uplink data on a physical uplink shared channel,
wherein the transmission circuitry is configured to, programmed to, or configured and programmed to,
in a first case that the first DCI is received
transmit the first uplink data without transmitting the second uplink data, and
keep the second uplink data in a buffer, and
in a second case that the second DCI is received after the first DCI is received,
transmit the second uplink data.
