Abstract:
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.

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.
Abstract:
Methods for transmitting and receiving data of a station includes setting a direct route to a corresponding station and a relay route to a relay device, selecting one route as between the direct route and relay route, and transmitting and receiving data through the selected route. A non-transitory computer-readable storage medium may store a program including instructions to cause a computer to perform the method. The setting may be performed by a processor and the transmitting and receiving may be performed respectively by a transmitter and a receiver.
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:
An apparatus for cell management in a mobile communication system based on a beam forming scheme includes: a storage unit storing a cell management scenario for at least one floating cell inlayed with a fixed cell of a base station and managed by the base station or other base stations; a determination unit determining a processing scheme of the at least one floating cell on the basis of the cell management scenario stored in the storage unit when a service request event is generated within the fixed cell; and a controller processing the at least one floating cell on the basis of the cell management scenario corresponding to the determined processing scheme.

Abstract:
A method and an apparatus for detecting a collision in a wireless multi-access channel are disclosed. The method of detecting the collision in the wireless multi-access according to an exemplary embodiment includes generating a request-to-send (RTS) message by a transmission terminal, transmitting the RTS message to a reception terminal, and receiving a response message from the reception terminal and determining whether a collision occurs based on a number of pieces of tone information included in the response message.
Abstract:
Disclosed is an apparatus and method for near field communication in an ultra wideband (UWB). An apparatus for near field communication in an UWB may include a determiner to determine the number of repetitions of a first sequence in each of n preambles, n denoting a natural number, and a processor to generate n short preambles by repeatedly arranging the first sequence based on the determined number of repetitions, and to generate the n preambles by arranging a long preamble with respect to each of the generated n short preambles.
Abstract:
Provided is a communication system for transmitting data using a plurality of interference-free communication channels. A transmission apparatus may inactivate a portion from among a plurality of transmit antennas and thereby group transmit antennas into a plurality of antenna groups. A channel formed between each antenna group and a reception apparatus may have a relatively low correlation and thus, the may be assumed to be independent. Accordingly, the transmission apparatus and the reception apparatus may transmit data using separate interference-free communication channels.
