Abstract: A system information sending method is provided, to resolve a technical problem that UE may not receive a paging message when a DRX cycle is greater than an MP. A network device may separately set a modification period (namely, a first period) for first-type system information (which, for example, may include paging configuration information), to ensure that the first-type system information is not to be modified in the first period. For example, the first period may be greater than a DRX cycle. In this way, when a terminal device wakes up based on the DRX cycle, a time when the terminal device wakes up is still in the first period. The terminal device may normally receive a paging message indicating that the paging configuration information is to be modified, thereby obtaining new paging configuration information in time and avoiding missing a subsequent paging message.

Abstract: Example communication message sending methods and apparatus based on backoff duration are described. One example method includes that a terminal device sends an access request to a cell to which the terminal device belongs. The terminal device monitors a downlink control channel, and receives an access response message based on scheduling information on the downlink control channel. If the access response message carries a backoff access identifier, the terminal device determines a backoff parameter corresponding to the backoff access identifier in the access response message based on a correspondence that is pre-stored and that is between the backoff access identifier and the backoff parameter. The terminal device determines backoff duration based on the backoff parameter and an access resource interval period corresponding to the terminal device, and sends an access request to the cell after the backoff duration.

Abstract: A base station encodes antenna configuration information of a neighboring cell of a first cell, and sends encoded information relating to the antenna configuration information of the neighboring cell to a user equipment (UE). The UE is capable of communicating with the base station in the first cell. The UE receives the encoded information; decodes the antenna configuration information of the neighboring cell from the encoded information; and performs determination of predetermined time-frequency resource according to the antenna configuration information of the neighboring cell. The predetermined time-frequency resource is used by a base station of the neighboring cell for transmitting pilot measurement information.

Abstract: This application relates to wireless communications technologies, and in particular, to a random access device, method, and system. In a network device provided in this application, a processing module is configured to determine a same processing result for random access procedures initiated by N terminal devices in M terminal device sets, where M and N are positive integers; and a sending module is configured to send a same random access control message to the N terminal devices, where the random access control message indicates the same processing result determined by the processing module, the message includes terminal set identification information, and the terminal set identification information identifies the N terminal devices. The network device uses a same random access reject message to indicate the same processing result for the random access procedures to the N terminal devices.

Abstract: This application relates to the field of wireless communications technologies, and in particular, to a system message transmission technology, so as to resolve a system message update problem of a terminal device with DRX cycle. This application provides a terminal device, including: a receiving module, configured to receive a first system message; and a processing module, configured to: obtain first indication information from the first system message, and update system messages other than the first system message according to the obtained first indication information, where the first system message is periodically sent, and occupies a fixed physical resource location. The first indication information is sent in the first system message instead of a paging message. The terminal device may update the system messages other than the first system message according to the indication information, thereby updating all system messages.
