Abstract
Provided are a data transmission method and apparatus and a storage medium. The data transmission method includes that a first communication node succeeds in channel contention on a first channel; the first communication node performs channel detection on a second channel within the preset duration before the sending moment of the first channel to acquire a detection result; and the first communication node sends a notification frame to a second communication node on the second channel in response to the detection result being idle, where the notification frame is used for instructing the second communication node not to send data on the second channel.

- and
- wherein the notification frame comprises at least one of the following:
- a type of the notification frame;
- an identifier of the first channel;
- a sending duration of the first communication node on the first channel;
- or
- a sending moment of the first communication node on the first channel;
- wherein the identifier of the first channel comprises at least one of the following:
- a channel number, a central frequency point corresponding to the first channel, or a link number;
- wherein the second frequency interval threshold is used for indicating a minimum value of an absolute value of a difference between central frequency points corresponding to such two channels among channels of the second communication node that sending and receiving operations are allowed to be performed on the two channels simultaneously;
- and wherein
- sending and receiving operations are not allowed to be performed simultaneously on such two channels among the channels of the second communication node that an absolute value of a difference between central frequency points corresponding to the two channels is less than the second frequency interval threshold;
