Abstract
Disclosed in the present application is a method in which a user equipment (UE) performs inter-UE direct communication in a wireless communication system. More particularly, the method includes the steps of: transmitting a request message to an eNodeB for direct communication with a UE of another party; receiving sequence information from the eNodeB for time synchronization with the UE of the other party; detecting a transmission sequence to be made from the UE of the other party, using the sequence information; and performing the inter-UE communication with the UE Of the other party.
Claims8
A method for performing inter-user equipment (UE) direct communication of a user equipment in a wireless communication system, the method comprising:
- transmitting, by the UE to a base station, a message requesting for direct communication with a counterpart user equipment that is in communication with a counterpart base station different from the base station;
- receiving, by the UE from the base station, sequence information provided to the base station by the counterpart base station, the sequence information for time synchronization between the UE and the counterpart user equipment;
- detecting, by the UE based on the received sequence information, a sequence being transmitted from the counterpart user equipment during a threshold time period provided by one of the base station or the counterpart base station;
- and
- performing, by the UE, inter-UE direct communication with the counterpart user equipment upon detecting the sequence within the threshold time period.
A user equipment (UE) configured to perform inter-UE direct communication in a wireless communication system, the user equipment comprising:
- a transmitting module configured to transmit a message to a base station requesting for direct communication with a counterpart user equipment that is in communication with a counterpart base station different from the base station;
- a receiving module configured to receive from the base station sequence information provided to the base station by the counterpart base station, the sequence information for time synchronization between the UE and the counterpart user equipment;
- and
- a processor configured to detect, based on the received sequence information, a sequence being transmitted from the counterpart user equipment during a threshold time period provided by one of the base station or the counterpart base station,
- wherein the processor is configured to control the transmitting module and the receiving module, so as to perform inter-UE direct communication with the counterpart user equipment upon detecting the sequence within the threshold time period.
