RADIO TERMINAL, D2D COMMUNICATION CONTROL APPARATUS, BASE STATION, PRELIMINARY RELAY RADIO TERMINAL SELECTION METHOD, NON-TRANSITORY COMPUTER READABLE MEDIUM
First Claim
1. A radio terminal comprising:
- at least one memory storing instructions, andat least one processor configured to execute the instructions to;
receive determination information that can be used to determine whether each of a plurality of other radio terminals is capable of performing device-to-device (D2D) communication with another radio terminal; and
select, in a situation in which D2D communication is being performed with a relay radio terminal that performs cellular communication with a network, a radio terminal in which the determination information between the radio terminal and the relay radio terminal satisfies a predetermined condition among radio terminals that are capable of performing D2D communication, as a preliminary relay radio terminal.

Abstract
A D2D communication control apparatus (10) according to the present invention includes: a communication unit (11) configured to receive determination information that can be used to determine whether a plurality of radio terminals are capable of performing direct communication with another radio terminal; and a selection unit (12) configured to select, in a situation in which a first radio terminal included in the plurality of radio terminals is performing D2D communication with a relay radio terminal that performs cellular communication with a network, a radio terminal in which the determination information between the radio terminal and the relay radio terminal satisfies a predetermined condition among radio terminals capable of performing D2D communication with the first radio terminal, as a preliminary relay radio terminal.
