Abstract

A radio station includes, a controller configured to configure a bundled channel which is a channel group obtained by bundling a plurality of channels and first information related to the bundled channel, and perform control to generate a transmission opportunity for a second signal that requests an uplink resource for a first signal, according to an amount of data in the bundled channel and the first information, and a communicator configured to transmit the second signal to another radio station according to the transmission opportunity for the second signal, and receives a radio resource from the other radio station.

Claims (54)

1. A radio station comprising:

a controller configured to:

configure a bundled channel which is a channel group obtained by bundling a plurality of channels and first information related to the bundled channel, and

perform control to generate a transmission opportunity for a second signal that requests an uplink resource for a first signal, according to an amount of data in the bundled channel and the first information; and

a communicator configured to:

transmit the second signal to another radio station according to the transmission opportunity for the second signal, and

receives a radio resource from the another radio station,

wherein the radio resource is allocated to the data in the bundled channel and is not allocated to data in a channel not included in the bundled channel.

2. The radio station according to claim 1 , wherein

the communicator is further configured to transmit, when data in a channel that is not included in the bundled channel is generated, a signal for requesting a radio, resource for transmitting the channel.

3. The radio station according to claim 1 , wherein

the communicator is further configured to receive an RRC signal as a control signal including third information that is information for a configuration of the bundled channel.

4. The radio station according to claim 1 , wherein

the communicator is further configured to receive an RRC signal as a control signal including the first information.

5. The radio station according to claim 1 , wherein

the first information includes a first threshold related to the amount of the data in the bundled channel, and

the controller generates a transmission opportunity for the first signal when the amount of the data in the bundled channel is equal to or more than the first threshold.

6. The radio station according to claim 1 , wherein

the first signal is a buffer status report (BSR) including information related to an amount of data, and

the second signal is a scheduling request (SR) that requests a uplink radio resource.

7. The radio station according to claim 6 ,

wherein the first signal includes information related to an amount of data in each of channels including the bundled channel.

8. The radio station according to claim 5 ,

wherein the controller is further configured to perform the control of the generation of the transmission opportunity for the first signal according to a generation of data in the bundled channel.

9. The radio station according to claim 5 , wherein

the first information includes the first threshold,

the first signal includes information related to an amount of data in a first channel configuring the bundled channel, and

the controller is further configured to perform the control of the generation of a transmission opportunity for the first signal on the transmission opportunity for the first signal in the first channel, which is based on the amount of the data in the first channel, and generate the transmission opportunity for the first signal when the amount of the data in the bundled channel is equal to or more than the first threshold.

10. The radio station according to claim 5 ,

wherein the controller performs the control of a generation of the transmission opportunity for the first signal on the transmission opportunity for the first signal for a first channel configuring the bundled channel, which is according to an amount of data in the first channel.

11. The radio station according to claim 5 ,

wherein the controller further includes a guard timer,

the controller is further configured to:

activate the guard timer at timing of starting data accumulation in the bundled channel,

stop the guard timer at timing of transmitting the data in the bundled channel, and

generate the transmission opportunity for the first signal at time-out of the guard timer.

12. The radio station according to claim 11 ,

wherein a timer value in the guard timer is configured according to an allowable delay time for the data in the bundled channel.

13. The radio station according to claim 2 ,

wherein the communicator is further configured to not use, for transmission of the data in the bundled channel, the radio resource allocated to a channel other than the bundled channel.

14. A radio station comprising:

a communicator configured to receive, from another radio station, a second signal that requests an uplink resource for a first signal and is transmitted according to transmission opportunity for the second signal, the transmission opportunity for the second signal being generated according to an amount of data in a bundled channel which is a channel group obtained by bundling a plurality of channels and first information related to the bundled channel; and

a transmitter configured to transmit a radio resource that is allocated to the another radio station in response to reception of the second signal,

wherein the radio resource is allocated to the data in the bundled channel and is not allocated to data in a channel not included in the bundles channel.

15. A communication system comprising:

a first radio station; and

a second radio station, wherein

the first radio station is further configured to

configure a bundled channel which is a channel group obtained by bundling a plurality of channels and first information related to the bundled channel,

perform control to generate a transmission opportunity for a second signal that requests an uplink resource for a first signal, according to an amount of data in the bundled channel and the first information, and

transmit the second signal to the second radio station according to the transmission opportunity for the second signal,

the first radio station is further configured to

transmit a radio resource that is allocated to the first radio station in response to reception of the second signal,

wherein the uplink resource is allocated to the data in the bundled channel and is not allocated to data in a channel not included in the bundled channel.
