Abstract

A mobile communication system in which a mobile station apparatus transmits, to abase station apparatus, uplink data using a physical uplink shared channel assigned by an uplink data transmission permission signal, wherein the base station apparatus: transmits, to the mobile station apparatus, a radio resource control signal including information for specifying a physical format in transmitting reception quality information together with uplink data; and transmits, to the mobile station apparatus, the uplink data transmission permission signal including a transmission instruction of reception quality information, and wherein the mobile station apparatus transmits, to the base station apparatus, reception quality information together with uplink data using the physical uplink shared channel according to information for specifying the physical format in case that a transmission instruction of the reception quality information is included in the uplink data transmission permission signal.

Claims
