Abstract

In case that an uplink grand from a base station apparatus is detected on PDCCH, a data designated by the uplink grant, channel state information measured at the time of transmission are transmitted by PUSCH as an uplink transmission signal. Then, in case that a notice that indicates retransmission is received, the data to be retransmission and the channel state information measured at the time of retransmission are transmitted by PUSCH. Accordingly, the mobile station apparatus can transmit appropriate channel state information when designated to retransmission so that the base station apparatus can make an efficient communication control (scheduling) between the base station apparatus and the mobile station apparatus that is suitable for the current channel condition.

Claims

1. A mobile station apparatus transmitting uplink data to a base station apparatus, the mobile station apparatus comprising:

a scheduling unit for setting acknowledgment for the uplink data having been transmitted previously when receiving, from the base station apparatus, a transmission grant including information for indicating transmission of channel state information without the uplink data after the previous transmitting of the uplink data.

2. A method of a mobile station apparatus transmitting uplink data to a base station apparatus, the method comprising:

setting acknowledgment for the uplink data having been transmitted previously when receiving, from the base station apparatus, a transmission grant including information for indicating transmission of channel state information without the uplink data after the previous transmitting of the uplink data.
