## Abstract

A communication device includes a transmitter that transmits data; and a controller that causes, based on information indicating priority levels of respective radio resources of a plurality of radio resources and a priority level of the data, the transmitter to transmit the data using a radio resource provided with a priority level corresponding to the priority level of the data.

## Claims

### Claim 1

A communication device comprising:
a transmitter that transmits data; and
a controller that causes, based on information indicating priority levels of respective radio resources of a plurality of radio resources and a priority level of the data, the transmitter to transmit the data using a radio resource provided with a priority level corresponding to the priority level of the data.

### Claim 2 (depends on 1)

The communication device according to claim 1, wherein the communication device further includes a receiver that receives a signal, and
wherein the receiver receives a signal including the information indicating the priority levels of the respective radio resources of the plurality of radio resources.

### Claim 3 (depends on 1)

The communication device according to claim 1, wherein the controller configures the plurality of radio resources and assigns the priority levels to the respective radio resource of the configured plurality of resources.

### Claim 4 (depends on 1)

The communication device according to claim 1, wherein, when a synchronization signal is to be transmitted, the controller causes the transmitter to transmit the synchronization signal through a radio resource with a highest priority level, among the plurality of priority levels of the respective plurality of radio resources.

### Claim 5 (depends on 1)

The communication device according to claim 1, wherein, when a control signal is to be transmitted, the controller causes the transmitter to transmit the control signal through a radio resource with a highest priority level, among the plurality of priority levels of the respective plurality of radio resources.

### Claim 6

A communication device comprising:
a receiver that receives a signal transmitted from another communication device; and
a controller that causes, upon receiving the signal through a radio resource with a highest priority level among a plurality of priority levels of a respective plurality of radio resources, the receiver to decode the received signal, and that causes, upon receiving the signal through a radio resource with a priority level lower than the highest priority level, the receiver to discard the received signal.
