Document Type and Number:
WIPO Patent Application WO/2023/163397
Kind Code:
A1
Abstract:
Provided is a sounding procedure for pairing antenna ports distributed in a DAS and a reception STA in a wireless LAN system. Specifically, the reception STA receives NDPA from a transmission STA. The reception STA receives an NDP from the transmission STA. The reception STA receives a trigger frame from the transmission STA. The reception STA transmits feedback information to the transmission STA. The transmission STA operates in a system in which a plurality of antenna ports are distributed. A first primary 20 MHz channel is a primary 20 MHz channel present in one BSS. Second primary 20 MHz channels are additional primary 20 MHz channels for the plurality of antenna ports, respectively.
