Claim of US Patent No. 10,560,886

8. A Relay user equipment (UE) for transmitting and receiving a signal in a wireless communication system, the Relay UE comprising:a communication module including a transceiver configured to communicate with the external entity in a wireless or a wired manner; and
a processor functionally connected to the communication module, wherein the processor is configured:
to transition the Relay UE to a Remote UE mode;
while in the Remote UE mode, to monitor a channel through which plural neighbor Relay UEs communicate;
to receive relay-related system information including information that state information for the plural neighbor Relay UEs is transmitted for a specific period through the monitored channel;
to receive, from the plural neighbor Relay UEs, the state information based on the information;
to transmit a request for additional information to the plural neighbor Relay UEs when the additional information is determined to be necessary based on the state information;
to receive the additional information from the plural neighbor Relay UEs;
to transmit a connection request, for transmitting and receiving the signal, to a neighbor Relay UE determined among the plural neighbor Relay UEs based on the additional information;
wherein the state information includes battery state information of the plural neighbor Relay UEs,
wherein the battery state information includes at least one of a total battery capacity, a remaining battery life, or a remaining battery capacity, and
to receive a response to the connection request from the determined neighbor Relay UE,
wherein the additional information relates to a possibility of accommodating the Relay UE by the plural neighbor Relay UEs in consideration at least one of a current charging speed, a current discharging speed or the battery state information of the plural neighbor Relay UEs.
