## Abstract

A terminal includes: a transmission unit configured to transmit transport block to a first terminal using a resource selected in a resource pool; a reception unit configured to receive information related to resource selection from another terminal; and a control unit configured to select or reselect a resource in the resource pool. The transmission unit transmits a transport block to the first terminal using the selected or reselected resource.

## Claims

### Claim 1

A terminal comprising:
a transmission unit configured to transmit a transport block to a first terminal using a resource selected in a resource pool;
a reception unit configured to receive information related to resource selection from another terminal; and
a control unit configured to select or reselect a resource in the resource pool, based on the information related to resource selection, wherein
the transmission unit transmits a transport block to the first terminal using the selected or reselected resource.

### Claim 2 (depends on 1)

The terminal as claimed in claim 1, wherein
the reception unit receives the information related to resource selection from the first terminal.

### Claim 3 (depends on 1)

The terminal as claimed in claim 1, wherein
the reception unit receives the information related to resource selection from the first terminal and one or more terminals other than the first terminal.

### Claim 4 (depends on 3)

The terminal as claimed in claim 3, wherein
the reception unit receives the information related to resource selection that includes an identifier of the first terminal from the another terminal.

### Claim 5 (depends on 1)

The terminal as claimed in claim 1, wherein
the reception unit switches between receiving the information related to resource selection from the first terminal and receiving the information related to resource selection from the first terminal and one or more terminals other than the first terminal, based on a state of the terminal itself or of the first terminal.

### Claim 6

A communication method performed by a terminal, the communication method comprising:
transmitting a transport block to a first terminal using a resource selected in a resource pool;
receiving information related to resource selection from another terminal;
selecting or reselecting a resource in the resource pool, based on the information related to resource selection; and
transmitting a transport block to the first terminal using the selected or reselected resource.
