Abstract: Provided is a method and apparatus for setting a detour path in a wideband high frequency wireless system using a centralized Media Access Control (MAC) protocol. Here, in a wireless system using the centralized MAC protocol where a time synchronization and a band allocation may be performed by a single central control unit, when a signal blockage occurs while a data communication is being performed via a direct path between a source device and a destination device, the detour path may be quickly provided.

Abstract: A method of operating a network coordinator for a spatial reuse scheme includes receiving a reservation request for a time period for a data communication of a target transmitter/receiver pair that uses a directional antenna, searching for a time period reserved in advance for another transmitter/receiver pair, from a Channel Time Allocation Period (CTAP) that is a contention-free access period for the data communication, and reserving a time period for the target transmitter/receiver pair in the CTAP, so that the time period reserved for the target transmitter/receiver pair overlaps the time period reserved in advance for the other transmitter/receiver pair.

Abstract: The present invention relates to an apparatus and method for transmitting/receiving streaming data using multiple paths, in which the streaming data is smoothly reproduced without being interrupted, and more particularly, to an apparatus and method for transmitting/receiving streaming data using multiple paths, in which exchange of the streaming data is performed in real-time using the multiple paths regardless of obstacles. The method for transmitting streaming data using multiple paths includes managing and maintaining a path list including sequence information about a transmission path capable of transmitting data, framing the streaming data, and transmitting the framed streaming data via the transmission path according to the sequence information.

Abstract: Provided is an apparatus and method for transmitting and receiving data using multiple paths in a wireless communication system using a distributed Media Access Control (MAC). More particularly, provided is an apparatus and method for transmitting and receiving data that may select a path with a better channel status from multiple paths that include a direct path using a Line of Sight (LOS) and a relay path passing through a relay apparatus, in a wireless communication system that may transmit data via the LOS using a distributed MAC and a directional antenna.

Abstract: A method of allocating time for a communication device includes receiving a request for allocation of a second time period related to a second communication link, after allocating a first time period related to a first communication link, and reserving the portion of the second period overlapping the first period, wherein the first link is generated between first and second communication devices, and the second link is generated between third and fourth communication devices. A further aspect of the method includes identifying the first period reserved in advance, and receiving the request for allocating the second period, and allocating the second period to spatially overlap the first time period. A further aspect of the method includes identifying an existing reservation for the first period of the first link, receiving a new reservation for the second period, and allocating the second period to spatially overlap the first period.

Abstract: Disclosed are an apparatus and method for transmitting/receiving image data. The method for transmitting image data includes classifying each pixel of image data into upper bits and lower bits, enabling the classified upper bits to be included in a payload of a Most Significant Bit (MSB) packet, and also enabling the classified lower bits to be included in a payload of a Least Significant Bit (LSB) packet, generating a header of the MSB packet and a header of the LSB packet, combining the payload and the header to respectively generate the MSB packet and the LSB packet, and transmitting the generated MSB packet and the LSB packet.
