## Abstract

A communication device according to one embodiment includes a controller and a transmitter. The controller is configured to identify a zone that is a geographical section where the communication device is located, and select a predetermined transmission resource region from a plurality of transmission resource regions included in one transmission resource pool associated with the identified zone. The transmitter is configured to transmit a direct radio signal to another communication device by using a resource in the predetermined transmission resource region.

## Claims

### Claim 1

A communication device, comprising:
a controller and a transmitter, wherein
the controller is configured to:
identify a zone that is a geographical section where the communication device is located; and
select a predetermined transmission resource region from a plurality of transmission resource regions included in one transmission resource pool associated with the identified zone, and
the transmitter is configured to transmit a direct radio signal to another communication device by using a resource in the predetermined transmission resource region.

### Claim 2 (depends on 1)

The communication device according to claim 1, wherein
the controller is configured to perform a measurement of a radio signal in the plurality of transmission resource regions, and
the controller is configured to select the predetermined transmission resource region in accordance with a result of the measurement.

### Claim 3 (depends on 2)

The communication device according to claim 2, wherein
the controller is configured to select the predetermined transmission resource region according to a congestion degree based on the result of the measurement.

### Claim 4 (depends on 2)

The communication device according to claim 2, wherein
the controller is configured to select the predetermined transmission resource region based on a threshold value to be compared with the result of the measurement.

### Claim 5 (depends on 1)

The communication device according to claim 1, wherein
the controller is configured to select the predetermined transmission resource region based on a priority of transmission data to be transmitted using the direct radio signal.

### Claim 6 (depends on 1)

The communication device according to claim 1, wherein
the one transmission resource pool includes a plurality of transmission resource regions arranged in a frequency direction.

### Claim 7 (depends on 5)

The communication device according to claim 5, wherein the controller is configured to:
select configuration information in accordance with a movement speed of the communication device; and
select the predetermined transmission resource region from the plurality of transmission resource regions included in the one transmission resource pool, based on the selected configuration information.

### Claim 8

A processor for controlling a communication device, wherein the processor executes:
a process of identifying a zone that is a geographical section where the communication device is located,
a process of selecting a predetermined transmission resource region from a plurality of transmission resource regions included in one transmission resource pool associated with the identified zone, and
a process of transmitting a direct radio signal to another communication device by using a resource in the predetermined transmission resource region.
