Method and apparatus for transreceiving operating channel information in wireless communication system
First Claim
1. A method for transmitting operation parameters to a station by an access point (AP) of a basic service set (BSS) operating in television whitespace (TVWS), the method comprising:
- transmitting a frame including an operation information field, the operation information field including a subfield identifying a channel width of a BSS operating channel, the BSS operating channel comprising one or more basic channel units (BCUs); and
transmitting a SIG (signal) field in a preamble of a Physical layer Protocol Data Unit (PPDU);
wherein the SIG field includes a field identifying a BW (bandwidth) of a PPDU transmission band, the BW of the PPDU transmission band being less than or equal to the channel width of the BSS operating channel, andwherein a type of the PPDU is determined to be one of contiguous multi-BCUs, non-contiguous multi-BCUs or a single BCU based on a combination of the channel width of the BSS operating channel and the BW of the PPDU transmission band.

Abstract
The present invention relates to a wireless communication system, and more specifically, disclosed are a method and an apparatus for transreceiving operating channel information. A method for providing an operating parameter of a station, which operates in a whitespace band, according to the present invention, comprises the steps of: transmitting a frame comprising an operation information field including a channel width subfield; and transmitting a signal (SIG) field of a physical layer convergence procedure (PLCP) protocol data unit (PPDU) preamble, wherein the SIG field comprises a bandwidth (BW) field, and wherein the type of the PPDU can be determined on the basis of the channel width subfield and the BW field.
