Abstract

A mobile station is a mobile station configured to transmit data to a base station by performing priority control, and includes a memory and a processor coupled to the memory and configured to be capable of transmitting a plurality of pieces of data having different requirements corresponding to a plurality of channel groups, and be capable of, when performing the priority control, applying a radio resource specified by the base station to a channel group specified by the base station out of the channel groups and controlling transmission of the data.

First claim

What is claimed is:

1. A mobile station configured to transmit data to a base station by performing priority control, the mobile station comprising:
a transmitter configured to transmit, to the base station, a plurality of pieces of data having different requirements, each logical channel group of a plurality of logical channel groups corresponding to one of the different requirements; and
a controller circuitry configured to, when performing the priority control, apply a radio resource specified by the base station to a logical channel group specified by the base station among the logical channel groups and control, using the radio resource corresponding to each of the logical channel groups, transmission of the plurality of pieces of data in units of the logical channel groups, wherein
the controller circuitry is further configured to:
apply, when the logical channel group is a first logical channel group, a first radio resource as the radio resource to the first logical channel group,
apply, when the logical channel group is a second logical channel group, a second radio resource as the radio resource to the second logical channel group, and
the first radio resource is a resource allocated only for the first logical channel group.

2. The mobile station according to claim 1 , further comprising:
a receiver configured to receive first control information including resource information that specifies a first radio resource and group identification information that specifies a first channel group from the base station; and
wherein the controller circuitry is further configured to, according to the first control information, allocate the first radio resource to the first channel group and control transmission of data corresponding to the first channel group.

3. The mobile station according to claim 2 , further comprising:
a receiver configured to receive from the base station after receiving the first control information, second control information including resource information that specifies a second radio resource and group identification information that specifies a second channel group; and
wherein the controller circuitry is further configured to allocate, according to the second control information, the second radio resource to the second channel group and control transmission of data corresponding to the second channel group.

4. The mobile station according to claim 1 , wherein the channel groups correspond to a plurality of group identification information different from one another.

5. The mobile station according to claim 1 , wherein the channel groups correspond to a plurality of service quality identifiers different from one another.

6. The mobile station according to claim 1 , wherein the channel groups are set in advance for a single mobile station.

7. The mobile station according to claim 1 , wherein
the first radio resource is used only for transmission of data corresponding to the first logical channel group, and
the second radio resource is used for transmission of data corresponding to the second logical channel group.

8. A base station configured to transmit data to a mobile station by performing priority control, the base station comprising:
a transmitter configured to transmit a plurality of data having different requirements corresponding to a plurality of logical channel groups; and
a controller circuitry configured to, when performing the priority control, select a logical channel group out of the logical channel groups, apply a radio resource to the selected logical channel group, and control, using the radio resource corresponding to each of the logical channel groups, transmission of the plurality of data in units of the logical channel groups, wherein
the controller circuitry is further configured to:
apply, when the logical channel group is a first logical channel group, a first radio resource as the radio resource to the first logical channel group,
apply, when the logical channel group is a second logical channel group, a second radio resource as the radio resource to the second logical channel group, and
the first radio resource is a resource allocated only for the first logical channel group.

9. A communication system comprising:
a base station; and
a mobile station configured to transmit data to the base station by performing priority control, the mobile station including:
a transmitter configured to transmit a plurality of data having different requirements, each logical channel group of a plurality of logical channel groups corresponding to one of the different requirements, and controller circuitry configured to, when performing the priority control, apply a radio resource specified by the base station to a logical channel group specified by the base station out of the logical channel groups and control, using the radio resource corresponding to each of the logical channel groups, transmission of the plurality of data in units of the logical channel groups, wherein

the mobile station is further configured to:
apply, when the logical channel group is a first logical channel group, a first radio resource as the radio resource to the first logical channel group,
apply, when the logical channel group is a second logical channel group, a second radio resource as the radio resource to the second logical channel group, and
the first radio resource is a resource allocated only for the first logical channel group.

10. A communication system comprising:
a mobile station; and
a base station configured to transmit data to the mobile station by performing priority control, wherein the base station including:
a transmitter configured to transmit a plurality of data having different requirements, each logical channel group of a plurality of logical channel groups corresponding to one of the different requirements, and controller circuitry configured to, when performing the priority control, select a logical channel group out of the logical channel groups, apply a radio resource to the selected logical channel group, and control, using the radio resource corresponding to each of the logical channel groups, transmission of the plurality of data in units of the logical channel groups, wherein
the mobile station is further configured to:
apply, when the logical channel group is a first logical channel group, a first radio resource as the radio resource to the first logical channel group,
apply, when the logical channel group is a second logical channel group, a second radio resource as the radio resource to the second logical channel group, and
the first radio resource is a resource allocated only for the first logical channel group.

11. A communication method performed in a communication system including a base station and a mobile station configured to transmit data to the base station by performing priority control, wherein the mobile station capable of transmitting a plurality of data having different requirements, each logical channel group of a plurality of logical channel groups corresponding to one of the different requirements, is, when performing the priority control, capable of applying a radio resource specified by the base station to a logical channel group specified by the base station out of the logical channel groups and controlling, using the radio resource corresponding to each of the logical channel groups, transmission of the plurality of data in units of the logical channel groups, wherein the mobile station is capable of applying, when the logical channel group is a first logical channel group, a first radio resource as the radio resource to the first logical channel group, applying, when the logical channel group is a sec
