1. A method for transmitting a control signal, executed by a transmission node, the method comprising:
in a case that transmission of a first control signal meets a transmission limiting condition of a short control signal, transmitting the first control signal by listen before talk (LBT) of category 1, or transmitting the first control signal after performing channel listening by LBT of category 2,
wherein the method further comprises:
according to a to-be-transmitted position of the first control signal and a preset time length of a target observation window, determining the target observation window as: the preset time length ahead of an end position of the to-be-transmitted position of the first control signal;
determining that the transmission of the first control signal meets the transmission limiting condition of the short control signal according to transmission information of a target signal in the target observation window before transmitting the first control signal, wherein the target signal comprises: a signal transmitted according to the short control signal in the target observation window, and the first control signal,
wherein determining that the transmission of the first control signal meets the transmission limiting condition of the short control signal according to the transmission information of the target signal in the target observation window comprises:
determining that the transmission of the first control signal meets the transmission limiting condition of the short control signal in a case that the transmission information of the target signal in the target observation window meets the transmission limiting condition of the short control signal.
