Title:
METHOD AND DEVICE FOR RECEIVING PPDU BY COMBINING RU OR MRU IN PARTICULAR CHANNEL WITH RU OR MRU IN NEIGHBORING 20 MHZ CHANNEL IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/182729
Kind Code:
A1
Abstract:
Proposed are a method and a device for receiving a PPDU by combining an RU or an MRU in a particular channel with an RU or an MRU in a neighboring 20 MHz channel in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA. The reception STA decodes the PPDU to obtain control information. The reception STA decodes a data field of the PPDU on the basis of the control information. The control information comprises first or second information for an RU or an MRU in the bandwidth of the PPDU. The first information comprises first allocation information for a third MRU obtained by aggregating a first RU or a first MRU in a first channel with a second RU or a second MRU in a second channel. The first RU or the first MRU is a 242 tone RU, 106 tone RU, or a (106+26) tone MRU located on the boundary of the first channel which is adjacent to the second channel.
