Transmission method and device in wireless local area network

摘要

The disclosure claims a transmission method and device in WLAN, wherein the method includes: a transmitting STA or a receiving STA performing channel detection and/or channel scanning on a channel of the first channel set and/or the second channel set; if the result of the detection and/or scanning satisfies a preset condition, the transmitting STA and the receiving STA exchanging a reservation message on the channel of the first channel set or the second channel set, wherein the reservation message is configured to reserve a channel of the second channel set for transmission; the transmitting STA transmits a data frame to the receiving STA on the reserved channel of the second channel set; and after receiving the data frame, the receiving STA transmits acknowledgement information of the data frame on the channel of the first channel set or the second channel set.

1. A transmission method in Wireless Local Area Network (WLAN), comprising:
a transmitting Station (STA) or a receiving STA performing channel detection on a channel of a first channel set; or, a transmitting STA or a receiving STA performing channel detection on a channel of a second channel set; or, a transmitting STA or a receiving STA performing channel detection on a channel of a first channel set and a second channel set; or, a transmitting STA or a receiving STA performing channel scanning on a channel of a first channel set; or, a transmitting STA or a receiving STA performing channel scanning on a channel of a second channel set; or, a transmitting STA or a receiving STA performing channel scanning on a channel of a first channel set and a second channel set; or, a transmitting STA or a receiving STA performing channel detection and channel scanning on a channel of a first channel set; or, a transmitting STA or a receiving STA performing channel detection and channel scanning on a channel of a second channel set or, a transmitting STA or a receiving STA performing channel detection and channel scanning on a channel of a first channel set and a second channel set, if result of the detection satisfies a preset condition, or, if result of the scanning satisfies a preset condition, or, if result of the detection and the scanning satisfies a preset condition, then the transmitting STA and the receiving STA exchanging a reservation message on the channel of the first channel set or the second channel set, wherein the reservation message is configured to reserve a channel of the second channel set for transmission; the transmitting STA transmitting a data frame to the receiving STA on the reserved channel of the second channel set; and after receiving the data frame, the receiving STA transmitting acknowledgement information of the data frame on the channel of the first channel set or the second channel set; wherein the step of the transmitting STA and the receiving STA reserving the channel of the second channel set for transmission comprises: the transmitting STA and the receiving STA exchanging the reservation message on the channel to be reserved of the second channel set, or the transmitting STA and the receiving STA exchanging the reservation message on the channel, which is overlapped with the channel to be reserved, of the first channel set; wherein the reservation message carries: occupancy time required for transmission on the channel to be reserved.
