## Abstract

There is provided a communication apparatus including a setting unit that sets a resource for device-to-device communication, in which the setting unit sets a resource pool including a plurality of sub resource pools as a resource for the device-to-device communication. One of the sub resource pools is an anchor sub resource pool that stores control information for monitoring by the device that performs the device-to-device communication.

## Claims

### Claim 1

A communication apparatus, comprising:
a processor configured to:
set a first resource pool including a plurality of sub resource pools,
wherein the plurality of sub resource pools corresponds to a first resource for device-to-device communication; and
set a setting position of an anchor sub resource pool among the plurality of sub resource pools, wherein
the anchor sub resource pool is for a device that performs the device-to-device communication, and
the anchor sub resource pool stores control information monitored by the device;
set a second resource pool for each of the control information and first data associated with the anchor sub resource pool; and
set a third resource pool for second data associated with non-anchor sub resource pools of the plurality of sub resource pools.

### Claim 2 (depends on 1)

The communication apparatus according to claim 1, wherein
the processor is further configured to set the control information within the anchor sub resource pool, and
the set control information includes assignment information of one of the first data in the anchor sub resource pool or the second data in the non-anchor sub resource pools of the plurality of sub resource pools.

### Claim 3 (depends on 2)

The communication apparatus according to claim 2, wherein the assignment information indicates a sub resource pool of the plurality of sub resource pools to which third data is to be assigned.

### Claim 4 (depends on 1)

The communication apparatus according to claim 1, wherein
the processor is further configured to set the anchor sub resource pool to a center frequency of a frequency band, and
the frequency band corresponds to the first resource pool.

### Claim 5 (depends on 1)

The communication apparatus according to claim 1, wherein the processor is further configured to transmit a notification of the setting position of the anchor sub resource pool by a signaling process.

### Claim 6 (depends on 1)

The communication apparatus according to claim 1, wherein the processor is further configured to set a second resource for transmission of one of ACK or NACK by the device.

### Claim 7 (depends on 6)

The communication apparatus according to claim 6, wherein the processor is further configured to assign the second resource to a last subframe of each of the plurality of sub resource pools.

### Claim 8

A communication apparatus, comprising:
a processor configured to:
set a plurality of sub resource pools in a resource pool assigned from a base station,
wherein the plurality of sub resource pools corresponds to a first resource for device-to-device communication; and
set a setting position of an anchor sub resource pool among the plurality of sub resource pools, wherein
the anchor sub resource pool is for a device that performs the device-to-device communication, and
the anchor sub resource pool stores control information monitored by the device;
calculate a channel usage rate of a non-anchor sub resource pool of the plurality of sub resource pools; and
transmit a resource addition request to the base station in a case where the calculated channel usage rate is equal to or greater than a specific threshold.

### Claim 9 (depends on 8)

The communication apparatus according to claim 8, wherein
the processor is further configured to notify the base station of information regarding an unused sub resource pool of the plurality of sub resource pools, and
the unused sub resource pool is different from the anchor sub resource pool.

### Claim 10 (depends on 8)

The communication apparatus according to claim 8, wherein the processor is further configured to set a second resource for transmission of one of ACK or NACK by the device.

### Claim 11 (depends on 10)

The communication apparatus according to claim 10, wherein the processor is further configured to assign the second resource to a last subframe of each of the plurality of sub resource pools.

### Claim 12 (depends on 8)

The communication apparatus according to claim 8, wherein
in a case where a first frequency is insufficient with the anchor sub resource pool, the processor is further configured to assign the non-anchor sub resource pool of the plurality of sub resource pools to the first resource of the device-to-device communication, and
the non-anchor sub resource pool has a second frequency that is continuous with the first frequency.

### Claim 13 (depends on 8)

The communication apparatus according to claim 8, wherein the processor is further configured to transmit a notification of the setting position of the anchor sub resource pool by a signaling process.

### Claim 14

A terminal apparatus, comprising:
a processor configured to control device-to-device communication in a resource pool assigned by a communication apparatus, wherein
the resource pool includes a plurality of sub resource pools,
one of the plurality of sub resource pools is an anchor sub resource pool,
the communication apparatus sets a setting position of the anchor sub resource pool,
the anchor sub resource pool stores control information for the device-to-device communication, and
the communication apparatus:
calculates a channel usage rate of a non-anchor sub resource pool of the plurality of sub resource pools, and
transmits a resource addition request to a base station in a case where the calculated channel usage rate is equal to or greater than a specific threshold.

### Claim 15 (depends on 14)

The terminal apparatus according to claim 14, wherein the processor is further configured to monitor the stored control information in the anchor sub resource pool.
