Abstract: Disclosed is a protocol for transmitting data through cooperation between access points in an overlapped basic service set (OBSS) environment. A cooperative beamforming communication method may include negotiating, by a first access point, a cooperative transmit beamforming with a second access point having an OBSS area with the first access point; transmitting, by the first access point, a clear-to-send (CTS) to the second access point; and performing, by the first access point, the cooperative transmit beamforming with the second access point during a cooperative transmit beamforming duration determined through the negotiation after a predetermined time interval is elapsed, when transmission of the CTS is completed.

Abstract: A method for a communication link establishing device to establish a communication link in a targeted communication system is provided. A source terminal transmits a source terminal's identification information and threshold value information for selecting a relative angle measurement target to neighboring terminals including a target terminal, and transmits a relative angle measurement request signal to the target terminal and the neighboring terminals. Upon receipt of a response signal for the relative angle measurement request signal from at least one of the neighboring terminals including the target terminal, a communication link with the selected communication target's terminal is established based on the information contained in the response signal.

Abstract: An apparatus for spatial filtering receives a signal transmitted from a first terminal and detects a synchronization start point in time from a transmission frame included in the signal. The apparatus for spatial filtering demodulates a user-defined sequence included in the transmission frame and the at least one SRJBF sequence when the synchronization start point in time is detected, and then estimates a relative angle based on the demodulated user-defined sequence and SRJBF sequence.

Abstract: Provided is a system and method for configuring a multi-hierarchical cell in which a large-scale mobile backhaul technology and a small cell technology are combined. A mobile backhaul may increase a transmission capacity of a wireless backhaul using a super high frequency (SHF)/extremely high frequency (EHF) band, rather than a cellular band having a limitation in extending frequency resources, and a small group cell to be formed at a final end of the mobile backhaul may be configured by fixed group cells or mobile group cells depending on a radio environment, using a moving relay, wireless fidelity (WiFi), femto-cells, and the like, whereby cells may be miniaturized effectively, and a relatively great capacity of a wireless system may be provided to a subscriber.
