Embodiments of the present disclosure relate to methods and devices for broadcast signaling transmission. In example embodiments, the network device transmits first broadcast signaling in a first time duration of a first transmission window within a first transmission period. The network device then communicates with a terminal device in a broadcasting gap between the first time duration and a second time duration of the first transmission window subsequent to the first time duration. Further, the network device transmits the first broadcast signaling in the second time duration. In this way, the interruptions caused by the long-time period reserved for the broadcast signaling transmission may be reduced.
