Abstract: PURPOSE: A power control method of a device-to-device(D2D) communication terminal, and a D2D communication session opening method are provided to reflect a channel gain between communication terminals using wireless sources which are identical with the D2D communication terminal when power of the D2D communication terminal is controlled. CONSTITUTION: When first communication terminals(420,430) performing D2D communication use wireless sources which are identical with a second communication terminal which communicates with a base station(410), the base station measures a first channel gain between the first communication terminals and the second communication terminal. The base station controls transmission power of the first communication terminals in order not to generate radio frequency interference in the second communication terminal by a signal transmitted by the first communication terminals. The base station measures a second channel gain between the first communication terminals and the base station. [Reference numerals] (410) Base station; (420) Terminal i; (430) Terminal j; (440) Terminal k; (AA) Communication link through the base station; (BB) Direct communication link between the terminals

Abstract: The present invention relates to a method for scheduling in a device-to-device (D2D) communications system. The method for scheduling a link of a terminal in the D2D communications system includes the steps of: collecting information to show an medium access state of at least one adjacent link at a preset period; determining at least one link estimated to actually access a medium in a corresponding traffic slot among links with higher priority than the terminal based on the collected information, when the medium access state of the terminal is determined; and determining the medium access state of the terminal by considering at least one link estimated to actually access the medium.

Abstract: PURPOSE: A connection management method for a terminal in a heterogeneous network is provided to effectively connecting a service of a mobile communication network to a WLAN(wireless local area network) by managing connection between the WLAN and the mobile communication network. CONSTITUTION: A terminal initializes a communication operation state as one of the three states defined in a state diagram(S210). The terminal periodically determines the satisfaction of state transition conditions. The terminal updates or maintains the communication operation state based on a determination result(S220). The terminal transmits and receives data through a communication network corresponding to the maintained or updated communication operation state(S230). While a mobile communication network interface and a WLAN interface are operating, the terminal periodically repeats data transmission and reception, and the maintenance and update of the communication operation state(S240).
