Abstract:
The present invention relates to a method for scheduling a node in a device to device (D2D) system. According to an embodiment of the present invention, the method for scheduling the node in the D2D system comprises the steps of acquiring a first transmission rate of a first link in consideration of interference if a second link is established; acquiring a second transmission rate of the first link if the second link is not established; acquiring a third transmission rate of the second link if the second link is established; and determining whether the second link is established in consideration of the first transmission rate, the second transmission rate, and the third transmission rate. According to an embodiment of the present invention, the method can provide efficiently scheduling.
Abstract:
PURPOSE: A method and apparatus for valancing loads and for allocating power based on the load prediction of neighbor cells are provided to minimize load terminals by determining a power and handover terminal group. CONSTITUTION: A reception unit(300) receives information for predicting each load of neighbor base stations from the neighbor base stations. A first determination unit(306) determines a power and handover terminal group based on information for predicting each load of the neighbor base station. A control unit(302) determines the power and handover terminal group for minimizing load terminals using information for predicting the load of the neighbor base station. The load terminal includes a minimum demand transmission rate which is bigger than an average reception rate.

Abstract:
The present invention relates to a method and a device for locating an adjacent terminal in a device-to-device communication system. The method for locating adjacent terminal in device-to-device communication system using the device includes the steps of: broadcasting a search request signal indicating that the device intends to find an adjacent terminal when an adjacent terminal search event is detected using a search request resource area repeated according to a first period; and broadcasting a detection signal indicating the presence of a transmission terminal or receiving the detection signal from another terminal by using the search resource areas repeated according to a second period within the first period for which the search request signal is broadcasted. The first period is set to be equal to or greater than the second period.
