Abstract
Embodiments of the present invention provide a method and an apparatus for establishing a transmission mode, which relates to the field of network technologies, ensure backward compatibilities of an existing WLAN system and a next generation WLAN system, realize introduction of a new technology in the next generation WLAN protocol during data transmission, and improve network performance. The method includes: transmitting, by an access point AP, a first Clear To Send frame to a first station STA, to enable the first STA to set duration of a network allocation vector NAV of the first STA and remain in a silent state when the AP communicates with a second STA; transmitting the first Clear To Send frame to the second STA, to enable the second STA to process a Green Phase operation; and communicating with the second STA in a Green Phase period. The present invention is applied in data transmission.
