摘要： A network out-of-synchronization state processing method and apparatus, and a network access method and apparatus are provided. The method includes: if a first network device does not receive, in a first time length after the first network device determines that a terminal is in a network out-of-synchronization state, a measurement message reported by a second network device in a signal coverage area of the first network device, instructing at least one second network device in the signal coverage area of the first network device to send paging signaling to the terminal; and setting a network status of the terminal to a detached state if the first network device determines that in a second time length, no second network device in the signal coverage area of the first network device receives a paging response sent by the terminal, and that the terminal is still in the network out-of-synchronization state.

摘要： This application provides a method and an apparatus for obtaining system information SI. The method includes: sending, by a terminal device, a first message to a network device, where the first message includes first request information used to request first system information SI; and detecting, by the terminal device, a second message and obtaining the first SI, where the second message includes information used to respond to the request of the first request information. The terminal device may send the first request information to the network device based on an actual requirement, and detect the second message on a preset time-frequency resource.

摘要： An information sending and receiving method and an apparatus are disclosed. In an embodiment an information sending apparatus includes a processor configured to determine, based on a physical broadcast channel (PBCH) period or a synchronization signal block burst set (SS block burst set) period, a period in which remaining minimum system information (RMSI) is to be sent and a sender configured to send the RMSI to a terminal device by using X as the period, wherein X is a multiple of the PBCH period, or X and the PBCH period are in a one-to-one correspondence or a one-to-many relationship, and wherein a network device is configured to send at least one piece of RMSI by using at least one beam or antenna port.

摘要： Embodiments provide a method for transmitting a downlink control signal, and an apparatus. The method includes: sending, by a base station, one or more radio frames, where the one or more radio frames include a plurality of OFDM symbols that carry synchronization signals, each OFDM symbol that carries a synchronization signal is sent by using one or more downlink beams of the base station, and the OFDM symbol that carries the synchronization signal further carries a downlink control signal. The downlink control signal is placed in the OFDM symbol that carries the synchronization signal.

摘要： Embodiments of this application disclose a data receiving method, a data sending method, a data transmission method, and a related apparatus and system. The method includes: sending, by a network device in each transmission subwindow corresponding to a broadcast signal, the broadcast signal to user equipment by using a different antenna port, where the transmission subwindow is obtained by dividing, based on preset subwindow information, a transmission window corresponding to the broadcast signal; and determining, by the UE, a transmission subwindow in which a downlink transmit beam is located; and receiving the broadcast signal in a time in which the transmission subwindow is located, where the time in which the transmission subwindow is located is calculated based on the pre-obtained subwindow information.
