Abstract

A mobile station (MS) transmits, to a base station (BS), uplink data on a PUSCH, the PUSCH is assigned by using a PDCCH. The MS receives, from the BS, a radio resource control signal including first information instructing the MS to periodically transmit first reception quality information (RQI), the radio resource control signal including second information for determining an amount of resources for second RQI transmitted on the PUSCH, and third information instructing the MS to transmit the second RQI on the PUSCH; and transmits, to the BS, only the second RQI on the PUSCH in a case that the transmission of the first RQI which is instructed by using the first information and the transmission of the second RQI which is instructed by using the third information would occur at the same time, wherein the amount of resources for the second RQI is determined based on the second information.

Claims

1. A base station apparatus in a mobile communication system in which a mobile station apparatus is configured to transmit, to the base station apparatus, uplink data on a physical uplink shared channel, the physical uplink shared channel is 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 instructing the mobile station apparatus to periodically transmit first reception quality information,

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

the transmitting unit configured to transmit on the physical downlink control channel, to the mobile station apparatus, third information instructing the mobile station apparatus to transmit the second reception quality information on the physical uplink shared channel; and

a receiving unit configured to only receive, from the mobile station apparatus, the second reception quality information on the physical uplink shared channel in a case that the transmission of the first reception quality information which is instructed by using the first information and the transmission of the second reception quality information which is instructed by using the third information would occur at the same time, wherein

the amount of resources for the second reception quality information is determined based on the second information.

2. The base station apparatus according to claim 1, wherein

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

3. The base station apparatus according to claim 2, wherein

the second reception quality information is transmitted together with the uplink data on the physical uplink shared channel.

4. A mobile station apparatus in a mobile communication system in which the mobile station apparatus is configured to transmit, to a base station apparatus, uplink data on a physical uplink shared channel, the physical uplink shared channel is 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 instructing the mobile station apparatus to periodically transmit first reception quality information,

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

the receiving unit configured to receive on the physical downlink control channel, from the base station apparatus, third information instructing the mobile station apparatus to transmit the second reception quality information on the physical uplink shared channel; and

a transmitting unit configured to only transmit, to the base station apparatus, the second reception quality information on the physical uplink shared channel in a case that the transmission of the first reception quality information which is instructed by using the first information and the transmission of the second reception quality information which is instructed by using the third information would occur at the same time, wherein

the amount of resources for the second reception quality information is determined based on the second information.

5. The mobile station apparatus according to claim 4, wherein

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

6. The mobile apparatus according to claim 5, wherein

the second reception quality information is transmitted together with the uplink data on the physical uplink shared channel.

7. A communication method of a base station apparatus in a mobile communication system in which a mobile station apparatus is configured to transmit, to the base station apparatus, uplink data on a physical uplink shared channel, the physical uplink shared channel is assigned by using a physical downlink control channel, the communication method comprising:

transmitting, to the mobile station apparatus, a radio resource control signal including first information instructing the mobile station apparatus to periodically transmit first reception quality information;

transmitting, to the mobile station apparatus, the radio resource control signal including second information for determining an amount of resources for second reception quality information transmitted on the physical uplink shared channel;

transmitting on the physical downlink control channel, to the mobile station apparatus, third information instructing the mobile station apparatus to transmit the second reception quality information on the physical uplink shared channel; and

only receiving, from the mobile station apparatus, the second reception quality information on the physical uplink shared channel in a case that the transmission of the first reception quality information which is instructed by using the first information and the transmission of the second reception quality information which is instructed by using the third information would occur at the same time, wherein

the amount of resources for the second reception quality information is determined based on the second information.

8. The communication method according to claim 7, wherein

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

9. The communication method according to claim 8, wherein

the second reception quality information is transmitted together with the uplink data on the physical uplink shared channel.

10. A communication method of a mobile station apparatus in a mobile communication system in which the mobile station apparatus is configured to transmit, to a base station apparatus, uplink data on a physical uplink shared channel, the physical uplink shared channel is assigned by using a physical downlink control channel, the communication method comprising:
