Abstract: A communication method for a transmitter using a preamble in a wireless communication system comprises the steps of: determining two or more subcarriers from among a plurality of subcarriers for the preamble; mapping a subcarrier sequence of the preamble and a subcarrier phase value to the two or more subcarriers; and transmitting the preamble using the two or more subcarriers. Here, the preamble comprises a mistake element including a first repetitive pattern, and an imaginary element including a second repetitive pattern, which are within a preset time period of a time domain; and the relationship between the first repetitive pattern and the second repetitive pattern shows the characteristic information of the wireless communication system.

Abstract: Provided is an apparatus for controlling subcarrier spacing in a system supporting multiple frequency bands. The apparatus for controlling a subcarrier spacing comprises: an interference detection unit detecting interference over multiple frequency bands; a system parameter provision unit providing system parameters related to a subcarrier spacing between the multiple frequency bands - for example RF, FFT size, and channel bandwidth; a subcarrier spacing control unit controlling the subcarrier spacing such that the detected interference is reduced, on the basis of the system parameters. In a system operating with multiple bands, different subcarrier spacing can be applied by each band, thereby controlling interference occurring in each band.

Abstract: Es sind ein Verfahren zum Senden und Empfangen eines Frames in einem drahtlosen lokalen Netzwerk-(WLAN-)System und eine Vorrichtung für dieses Verfahren offenbart. Ein Verfahren zum Erzeugen von Interferenz/Nichtinterferenzstationslisten enthält ein Empfangen eines ersten Frames von einer zweiten Station, ein Erlangen einer Empfängeradresse des ersten Frames von dem ersten Frame, und, basierend darauf, ob ein zweiter Frame, der eine Antwort auf den ersten Frame ist, von einer durch die Empfängeradresse angezeigten dritten Station innerhalb einer voreingestellten Zeit ab einer Zeit, zu welcher der erste Frame empfangen worden ist, zu empfangen ist, Einstellen der dritten Station als eine Interferenzstation oder eine Nichtinterferenzstation. Daher kann die Leistungsfähigkeit eines Kommunikationssystems verbessert werden.
