Abstract

A mobile communication system in which a mobile station apparatus transmits, to a base 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

1. A base station apparatus in a mobile communication system in which a mobile station apparatus transmits, to the base station apparatus, uplink data on a physical uplink shared channel assigned by using a physical downlink control channel, the base station apparatus comprising:

a transmitting unit configured to transmit, to the mobile station apparatus, a radio resource control signal including first information for determining an amount of resources for reception quality information transmitted together with the uplink data on the physical uplink shared channel; and

the transmitting unit configured to transmit on the physical downlink control channel, to the mobile station apparatus, second information instructing a transmission of the reception quality information on the physical uplink shared channel assigned by using the physical downlink control channel, wherein

the reception quality information of which the transmission is instructed by using the second information is transmitted together with the uplink data on the physical uplink shared channel, and

the amount of resources for the reception quality information transmitted together with the uplink data on the physical uplink shared channel is determined based on the first information and a size of the physical uplink shared channel assigned by using the physical downlink control channel.

2. A mobile station apparatus in a mobile communication system in which the mobile station apparatus transmits, to a base station apparatus, uplink data on a physical uplink shared channel assigned by using a physical downlink control channel, the mobile station apparatus comprising;

a receiving unit configured to receive, from the base station apparatus, a radio resource control signal including first information for determining an amount of resources for reception quality information transmitted together with the uplink data on the physical uplink shared channel,

the receiving unit configured to receive on the physical downlink control channel, from the base station apparatus, second information instructing a transmission of the reception quality information on the physical uplink shared channel assigned by using the physical downlink control channel; and

a transmitting unit configured to transmit, to the base station apparatus, the reception quality information together with the uplink data on the physical uplink shared channel assigned by using the physical downlink control channel in response to the second information being received from the base station apparatus, wherein

the amount of resources for the reception quality information is determined based on the first information and a size of the physical uplink shared channel assigned by using the physical downlink control channel.

3. A base station apparatus in a mobile communication system in which a mobile station apparatus transmits, to the base station apparatus, uplink data on a physical uplink shared channel assigned by using a physical downlink control channel, the base station apparatus comprising:

a transmitting unit configured to transmit, to the mobile station apparatus, a radio resource control signal including first information for determining an amount of resources for reception quality information transmitted together with the uplink data on the physical uplink shared channel; and

the transmitting unit configured to transmit on the physical downlink control channel, to the mobile station apparatus, second information permitting a transmission of the reception quality information together with the uplink data on the physical uplink shared channel assigned by using the physical downlink control channel, wherein

the amount of resources for the reception quality information of which the transmission is permitted by using the second information is determined based on the first information and a size of the physical uplink shared channel assigned by using the physical downlink control channel.

4. A mobile station apparatus in a mobile communication system in which the mobile station apparatus transmits, to a base station apparatus, uplink data on a physical uplink shared channel assigned by using a physical downlink control channel, the mobile station apparatus comprising;

a receiving unit configured to receive, from the base station apparatus, a radio resource control signal including first information for determining an amount of resources for reception quality information transmitted together with the uplink data on the physical uplink shared channel,

the receiving unit configured to receive on the physical downlink control channel, from the base station apparatus, second information permitting a transmission of the reception quality information together with the uplink data on the physical uplink shared channel assigned by using the physical downlink control channel; and

a transmitting unit configured to transmit, to the base station apparatus, the reception quality information together with the uplink data on the physical uplink shared channel assigned by using the physical downlink control channel in response to the second information being received from the base station apparatus, wherein

the amount of resources for the reception quality information is determined based on the first information and a size of the physical uplink shared channel assigned by using the physical downlink control channel.
