Abstract: An operation method of a terminal in a wireless communication system includes: transmitting uplink (UL) traffic information indicating a size of a UL data signal to a base station; receiving a jamming message generated based on the UL traffic information from the base station; generating an uplink (UL) transmission signal including the UL data signal and a UL jamming signal based on the jamming message; and transmitting the UL transmission signal to the base station. Also, the jamming message indicates a pattern of the UL jamming signal, the UL transmission signal is transmitted in a same frequency band as a frequency band in which a downlink (DL) transmission signal of the base station is received, and the UL jamming signal is transmitted in remaining resources excluding resources occupied by the UL data signal in the frequency band.

Abstract: A discovery method is provided by a device in a D2D direction communication. The device selects a discovery resource unit from among discovery resource units which are not being used after listening during one or more discovery resource periods. The device transmits a first discovery signal through the selected discovery resource unit in a broadcasting manner at a first discovery resource period, and transmits a second discovery signal through the selected discovery resource unit in a query-based manner at a second discovery resource period.

Abstract: A D2D direct communication method is provided. The device sets at least one frame among a plurality of frames included in a superframe to a frame type 0 which is sectionized into a synchronization region for performing a synchronization procedure, a discovery region for discovering devices, a peering region for a connection, and a data region for scheduling of resources and data transmission. The device sets remaining frames among the plurality of frames to a frame type 1 which is sectionized into the synchronization region and the data region.

Abstract: An exemplary embodiment of the present invention provides a resource management method performed by a coordinator for controlling interference between cells. The coordinator receives a channel state of a second base station neighboring a first base station from the first base station. The coordinator partitions a resource based on the channel state. The coordinator allocates the partitioned resource to the first base station. In addition, the coordinator transmits a first message requesting resource management to be set to the first base station. Here, the first message includes information on the allocated resource.

Abstract: A mobile relay station (RS) and a handover method thereof are provided. When it is determined that a mobile RS performs handover from a superordinate base station (BS) to a target BS, information indicating admission of handover is received from the superordinate BS. The mobile RS transmits a service unavailability section to a subordinate terminal, whereby the subordinate terminal is prevented from performing handover to a different BS or a different RS.
