The embodiments of the present application propose a method for determining a signal transmission occasion, including: acquiring configuration information of a transmission resource of an uplink signal; determining, based on the configuration information, a resource occasion where the uplink signal is transmitted; initiating a Listen Before Talk (LBT) operation before the resource occasion; determining whether the LBT operation is successful; transmitting the uplink signal at the resource occasion if the LBT operation is successful; and determining a next resource occasion where the uplink signal can be transmitted based on the configuration information if the LBT operation fails. The embodiments of the present application further propose corresponding device and computer storage medium.
