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: A terminal device camps on a first cell in an idle state or an inactive state. The terminal device measures the first cell based on a first non-cell defining synchronization signal/physical broadcast channel block (NCD-SSB) frequency, and measures a second cell based on the first NCD-SSB frequency and/or a cell defining synchronization signal/physical broadcast channel block (CD-SSB) frequency. The terminal device performs cell reselection based on a measurement result of the first cell and a measurement result of the second cell.

Abstract: This application discloses a communication method and a communication apparatus. The method includes: A terminal device receives wake-up information from a network device, and switches from a first state to a second state in response to the wake-up information. The wake-up information includes one or more of the following information: a first cell bar indication, a second cell bar indication, a resource configuration change indication, a resource configuration, and cell identification information. The first cell bar indication indicates whether a terminal device is allowed to select or reselect a cell. This application provides a new energy saving method. Before receiving the wake-up information, the terminal device does not perform other communication, to reduce energy consumption. In addition, the wake-up information may include cell bar indication information, so that the terminal device can select a suitable cell after the terminal device is waken up, and therefore communication efficiency is improved.

Abstract: A method to transmit information includes: obtaining, by a terminal in a disconnected state, information about a current coverage class of the terminal; and sending, by the terminal, a first message to an access network device, where the first message carries information about a coverage class of the terminal. The terminal in the disconnected state actively reports the information about the coverage class, so that a network device learns of the information about the coverage class of the terminal in a timely manner. In this way, during communication, a communication limitation or communication resource waste caused by inconsistency between information about a coverage class of the terminal that is stored on a network side and information about an actual coverage class can be avoided, and network resources can be fully used.

Abstract: The technology of this application relates to a paging method and an apparatus. A first device sends first signaling used to page a terminal device. The first signaling includes memory information or an identifier of the terminal device, to indicate the to-be-paged terminal device. In addition, the terminal device may further determine a first resource based on the first signaling, to send uplink data by using the first resource. The first device may also receive, on the first resource, the uplink data from the terminal device. The terminal device may determine the first resource based on the first signaling is equivalent to the first device allocating a resource to the terminal device. In this way, steps needing to be performed for data transmission between the terminal device and the first device are reduced.
