Abstract: A two-hop link transmission method and apparatus are provided. The method includes establishing a two-hop link and scheduling transmission on the two-hop link in a Device-To-Device (D2D) communication network. The two-hop link transmission method includes identifying neighbor terminals available for communication with the transmission terminal, selecting one of the neighboring terminals as a recipient terminal, determining a type of a link to be established with the selected neighboring terminal between a single-hop link and two-hop link types, selecting, when the two-hop link type is determined, a relay terminal among the neighboring terminals, establishing the two-hop link with the recipient terminal via the relay terminal, allocating a Multi-Hop Connection Identifier (MCID) for the two-hop link, and transmitting data to the recipient terminal through the two hop link.

Abstract: A device and a method for detecting abnormality in cell coverage in a wireless communication system are provided. A base station includes a communication interface, a memory, and a processor operatively coupled to the communication interface and the memory. The processor is configured to obtain information related to an abnormal area from a network management device. The processor is configured to identify, in a case in which a user equipment (UE) handovers from another base station to the base station, whether the abnormal area is provided by the other base station based on the information related to the abnormal area. The processor is configured to detect, in a case in which the abnormal area is provided by the other base station, whether cell coverage of the base station is affected by the abnormal area provided by the other base station, based on information related to timing advance (TA) of the other base station.

Abstract: The present invention relates to a method and an apparatus for supporting handover and, more particularly, to a method and an apparatus for adjusting handover related parameters. In order to achieve the above-described objective, a method for supporting handover by a base station in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: transmitting a handover parameter to a terminal, based on a handover purpose; receiving, from the terminal, a handover measurement report based on the handover parameter; storing information for the handover purpose; and transmitting, to a target base station, a handover request message including the information for the handover purpose.
