摘要： The disclosure discloses a method and an apparatus for transmission control, a device, and a storage medium which relate to the field of communication technology. The method includes the following. A terminal device receives indication information from a network device, where the indication information indicates that a satellite in communication with the terminal device performs feeder link switch between a first non-terrestrial network (NTN) gateway and a second NTN gateway, and the first NTN gateway and the second NTN gateway are connected to a same cell corresponding to the network device. The terminal device suspends UL transmission and/or DL transmission with the network device according to the indication information during the feeder link switch. In the disclosure, for two NTN gateways connected to the same cell, during the feeder link switch (hard switch) performed by the satellite between the two NTN gateways, the UL transmission and/or the DL transmission between the terminal device and the network device are suspended, so as to prevent the terminal device and the network device from performing unnecessary operations, thereby reducing the system overhead.
