Aspects of the invention relate to the technical field of wireless communication, and provides a time slot format indication method, apparatus, equipment and system, and a storage medium. The method can include transmitting time slot format indication information to User Equipment (UE) upon detecting that a target channel is in an idle state. The time slot format indication information is used for indicating upper and lower row formats of symbols in N time slots within a channel occupation period, the first time slot and/or the last time slot in the N time slots are/is a partial time slot, where N is a positive integer greater than or equal to 1, the channel occupation period refers to a period occupying the target channel by a base station, and the target channel is located on a non-authorized frequency spectrum.
