6. The method according to claim 5 , wherein when the first message is configured to be received in a carrier of the first PLMN, the second UE is preconfigured to periodically monitor the carrier of the first PLMN.

7. The method according to claim 5 , wherein when a specific condition is satisfied, the second UE transmits the sidelink communication data, and

wherein when the second UE is capable of transmitting the sidelink communication data to the first UE, while satisfying specific quality of service (QoS), the specific condition is satisfied.

8. The method according to claim 5 , further comprising reporting information related to use of transmission resources of the sidelink communication data to the first PLMN.

9. A first user equipment (UE) for receiving data in a wireless communication system, the first UE comprising:

a transceiver; and

a processor configured to:

transmit, to a second UE, a first message including a sidelink communication request by controlling the transceiver;

receive, from the second UE, a second message related to that the sidelink communication request has been accepted in response to the first message by controlling the transceiver; and

receive sidelink communication data from the second UE by controlling the transceiver,

wherein the sidelink communication data is for a non-public safety (PS)-related service,

wherein a type of the sidelink communication data is unicast,

wherein the first UE is a subscriber of a first public land mobile network (PLMN) and the second UE is a subscriber of a second PLMN different from the first PLMN,

wherein the sidelink communication data is received in a carrier of the first PLMN,

wherein the first message includes i) information on that even a UE subscribed to a PLMN other than the first PLMN is allowed to transmit data in a carrier of the first PLMN, and ii) information on that the UE is not charged for the data transmission in the carrier of the first PLMN, and iii) information on service code,

wherein a layer-2 identifier (ID) of the first UE is transmitted with the first message, and

wherein the data transmission from the second UE is charged to the first UE.

10. The first UE according to claim 9 , wherein the first message is transmitted in one of a carrier of the first PLMN, a carrier of the second PLMN, or a dedicated carrier for transmission of the first message.

11. The first UE according to claim 9 , wherein the processor is configured to report information related to use of reception resources of the sidelink communication data to the first PLMN by controlling the transceiver.

12. A second user equipment (UE) for transmitting data in a wireless communication system, the second UE comprising:

a transceiver; and

a processor configured to:

receive, from a first UE, a first message including a sidelink communication request from a first UE by controlling the transceiver,
