A method and apparatus for setting up a relay link to transfer a data frame using a relay in a wireless communication system are provided. The relay link setup method of a source STA in a wireless communication system may include receiving capability information of at least one relay supporting station included in the wireless communication system from an access point (AP) or a personal basic service set (PBSS) central point (PCP), selecting one of the at least one relay supporting station as a relay station, using beam forming information among the source station, a destination station, and the at least one relay supporting station and the capability information, transferring a relay link setup request frame to the destination station, and receiving a relay link setup response frame that includes information on a relay link setup result from the destination station. The relay link setup request frame and the relay link setup response frame may pass through the relay station.

Method and apparatus for setting up a relay link in a wireless communication system

A scheduling method of giving a chance for transmission to a plurality of terminals in the same time period, and a device therefor are provided. The scheduling method includes: transmitting first scheduling information to terminals in a network, the first scheduling information defining transmitting/receiving terminals and a transmission time period; receiving channel measurement information including inter-terminal interference information from the terminals in the network; and generating second scheduling information defining transmission time periods and a plurality of transmitting/receiving terminals that do not interfere with each other by using the channel measurement information.

Scheduling method and apparatus for spatial reuse

A method for setting up a relay link to transfer a data frame using a relay in a wireless communication system. The relay link setup method of a source in the system may include receiving capability information of at least one relay supporting station included in the system from an access point or a personal basic service set central point, selecting one of the at least one relay supporting station as a relay station, using beam forming information among the source station, a destination station, and the at least one relay supporting station and the capability information, transferring a relay link setup request frame to the destination station, and receiving a relay link setup response frame that includes information on a relay link setup result from the destination station. The relay link setup request frame and the relay link setup response frame may pass through the relay station.

Provided is a communication method of a coordinator, the method including: receiving a relay search request frame for requesting a search for at least one relay station between a destination station and a source station; and transmitting, in response to the relay search request frame, a relay search response frame including a list of the at least one relay station so that the source station selects a target relay station from the at least one relay station.

Communication method for a coordinator, a relay device, a source device and a destination device included in a wireless network

Disclosed is a method for adjusting a transmission time point of at least one second terminal in a wireless network by a first terminal. In the method for adjusting a transmission time point of a terminal, a transmission time point of the second terminal is set, a first frame including information regarding the transmission time point is transmitted to the second terminal, a first response frame transmitted according to the transmission time point from the second terminal is received, and the transmission time point is adjusted according to an arrival time of the first response frame.

Method and apparatus for adjusting signal transmission starting point of terminal in wireless network

A terminal identifying method identifies a terminal in a media access control layer, and includes allocating a station ID to the terminal for identifying the terminal, and allocating a flow ID to a connection in the terminal for identifying the connection in the terminal.

Identifying method and protocol data unit generating apparatus

In order to manage a neighbor list of neighboring base stations based on the location of a terminal communicating with a base station of a macrocell with femtocell deployments, the base station divides the macrocell in accordance with a predetermined standard of division, and generates a mobile neighbor advertisement message so as to periodically transmit the generated message to the terminal. At this time, the terminal identifies the current location thereof in the macrocell upon receipt of the pilot signals periodically transmitted from the base station of the macrocell. The terminal obtains information regarding the location of the terminal from the information regarding the femtocells deployed within the respective divided regions and information regarding macrocells neighboring the macrocell through using the mobile neighbor advertisement message to scan base stations.
