1. A data sending method, being applied to a first station (STA), wherein the first STA belongs to a first multi-link device (MLD), and the method comprises:
sending a notice-to-send message to a second STA, wherein the notice-to-send message is used to instruct that the first STA is prepared to send a data unit to the second STA in a first transmission opportunity (TXOP) obtained in advance, and the second STA belongs to a second MLD; and
performing the following operations based on a situation of a third STA receiving a data unit or the notice-to-send message in a duration of a preset inter-frame space:
sending a data unit to the second STA in the first TXOP, or stopping sending a data unit to the second STA; wherein the third STA belongs to the first MLD;
wherein the notice-to-send message at least comprises a first TXOP duration, the first TXOP duration at least comprises a short frame inter-frame space (SF-IFS), wherein the SF-IFS is determined according to the following objects:
a sending duration of the notice-to-send message between two STAs with a largest distance allowed, and a duration of processing the notice-to-send message by a MLD.
