Abstract: A method and an apparatus for scheduling a system information block are disclosed, to increase a probability of obtaining a system information block by a terminal. A network device sends a master information block to the terminal, where the master information block includes DMTC period information; and the terminal receives the master information block, and detects a system information block, at a location of a subframe in a DMTC period. Alternatively, the master information block includes DMTC period information and DMTC time window information, and the terminal detects a system information block, at a location of a subframe in a DMTC period and in a DMTC window size. Alternatively, the master information block includes system information block period information or MF system information block content change indication information, and the terminal determines, based on the system information block period information, whether content of the detected system information block is changed.

Abstract: Example coverage mode identification methods and apparatus are described. One example method includes determining a first coverage mode by a terminal. The terminal determines a preamble sequence based on the first coverage mode, and sends the preamble sequence to a base station, where the preamble sequence is used to determine the first coverage mode. Because the base station can determine the coverage mode of the terminal by using only the preamble sequence sent by the terminal, without using a channel used to receive a signal of the terminal, resources do not need to be grouped or planned, and there is no need to strictly distinguish between different coverage mode sets or groups.

Abstract: The present disclosure describes a video data processing method and a device. An example method includes: determining, by a network device, a video bitrate, a volume of scheduled video data, and video-played duration of a video service of a terminal; determining, by the network device, a buffer time of the video service of the terminal based on the video bitrate, the volume of scheduled video data, and the video-played duration; and performing, by the network device, video data scheduling on the terminal based on the buffer time.
