Abstract:
Disclosed is a method for retransmitting scheduling assignment (SA) information between half-duplex user equipment in a wireless communication system. The method for retransmitting SA information may comprise the steps of: receiving, through a first resource area, a D2D signal including first SA information transmitted by a second user equipment, and second SA information transmitted by a third user equipment; if the target user equipment of the second SA information is the second user equipment, determining whether to retransmit the second SA information for the second user equipment; and if it is determined to retransmit the second information, transmitting the second information through a second resource area.
