Abstract

A base station apparatus in a mobile communication system in which a mobile station apparatus transmits, to the base station apparatus, uplink data using a physical uplink shared channel assigned by an uplink data transmission permission signal. The base station apparatus includes a transmitting unit which is configured to transmit, to the mobile station apparatus, the uplink data transmission permission signal including first information for permitting the mobile station apparatus to transmit reception quality information together with the uplink data, wherein the transmitting unit which is configured to transmit, to the mobile station apparatus, the uplink data transmission permission signal including second information for permitting the mobile station apparatus to transmit the reception quality information without the uplink data.

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 using a physical uplink shared channel assigned by an uplink data transmission permission signal, the base station apparatus comprising:

a transmitting unit which is configured to transmit, to the mobile station apparatus, the uplink data transmission permission signal including first information for permitting the mobile station apparatus to transmit reception quality information together with the uplink data, wherein

the transmitting unit which is configured to transmit, to the mobile station apparatus, the uplink data transmission permission signal including second information for permitting the mobile station apparatus to transmit the reception quality information without the uplink data.

3. The base station apparatus according to claim 1, further comprising:

a receiving unit which is configured to receive, from the mobile station apparatus, the reception quality information.

2. A communication method of a base station apparatus in a mobile communication system in which a mobile station apparatus transmits, to the base station apparatus, uplink data using a physical uplink shared channel assigned by an uplink data transmission permission signal, the communication method comprising:

selectively transmitting, to the mobile station apparatus, either;

the uplink data transmission permission signal including first information for permitting the mobile station apparatus to transmit reception quality information together with the uplink data, or

the uplink data transmission permission signal including second information for permitting the mobile station apparatus to transmit the reception quality information without the uplink data.

4. The communication method according to claim 2, further comprising:

generating the uplink data transmission permission signal selectively including either the first information or the second information.
