Abstract: This application provides a system message processing method and apparatus. A terminal receives a master information block (MIB), and obtains indication information. The indication information indicates a type of the MIB. In this way, the terminal can process the MIB based on the type of the MIB. In other words, in embodiments of this application, the terminal may decode the MIB based on the type of the MIB. Therefore, the following case is avoided: The MIB is decoded in a fixed manner, and consequently, the MIB cannot be accurately parsed. In this way, communication efficiency is improved.

Abstract: This application relates to the field of communications technologies. Specifically, this application provides a scheduling method. In the method, when a terminal needs to send service data of an ultra-reliable and low latency communications service, the terminal sends a scheduling request to a base station, where the scheduling request carries buffer information in a buffer state report sent by the terminal to the base station in an original scheduling procedure. Therefore, compared with an existing scheduling procedure, in the scheduling method provided in this application, no buffer state report needs to be sent to the base station, thereby reducing steps of the scheduling procedure, and reducing a scheduling latency. To achieve an inventive concept of reducing the steps of the scheduling procedure, this application further provides a scheduling method for simplifying steps of a scheduling procedure. In addition, to ensure practical application and implementation of the scheduling method, this application further provides a corresponding scheduling device.

Abstract: A network device sends multicast configuration information to a terminal device, where the multicast configuration information corresponds to a first multicast service, the multicast configuration information includes first indication information, and the first indication information indicates that the terminal device sends first feedback information for the first multicast service. The terminal device receives the first multicast service based on the first multicast configuration information, and then sends the first feedback information corresponding to the first multicast service to the network device based on the first indication information in the first multicast configuration information. The feedback mechanism applies to a multicast transmission technology and improves transmission reliability of a multicast service.
