Title:
METHOD AND APPARATUS FOR TRANSMITTING C-OFDMA PPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/175785
Kind Code:
A1
Abstract:
Proposed is a method and apparatus for transmitting a C-OFDMA PPDU in a wireless LAN system. Specifically, a first AP transmits a C-OFDMA request frame to a second AP. The first AP receives a C-OFDMA response frame as a response to the C-OFDMA request frame from the second AP. The first AP transmits a first C-OFDMA PPDU to a first STA through a first channel. A second C-OFDMA PPDU is transmitted simultaneously together with the first PPDU through a second channel by the second AP. The C-OFDMA request frame includes first information indicating that using the second channel for the second AP is allowed. The first channel corresponds to a channel remaining after excluding a preamble-punctured channel from the entire channel, and the second channel corresponds to the preamble-punctured channel.
