Abstract: This application provides a communication method and apparatus, to resolve a problem that security is low when a tag is triggered to perform random access in a communication network. The method includes: receiving first signaling, and determining, based on the first signaling, a second mask stored at a first storage location; and performing random access when a first mask matches the second mask. The first signaling indicates the first storage location and the first mask, the first signaling carries a first mask identifier, and the first mask identifier identifies the first storage location and/or the first mask. In embodiments of this application, a correspondence between a mask identifier and a storage location and/or a correspondence between the mask identifier and a mask are/is negotiated in advance, so that a part or all of masks and storage locations can be implicitly indicated by using a mask identifier.

Abstract: This application provides a communication method and apparatus, to improve communication security. The method includes: receiving first system information from a network device, where the first system information includes a first signature; determining a first digest based on the first signature; determining a second digest based on the first system information; and if the first digest matches the second digest, storing or applying the first system information. In embodiments of this application, a signature is carried in a field of system information, so that both a terminal device that supports the signature and a terminal device that does not support the signature can complete decoding of the system information. Specifically, the terminal device that supports the signature may perform verification by using a signature obtained through decoding.

Abstract: This application provides a beam information obtaining method and an apparatus, relates to the field of communications technologies, and resolves a problem that resources of positioning reference signals are wasted because the positioning reference signals need to be omnidirectionally sent because of an unknown direction, of a terminal, caused by use of a beam, when the terminal is positioned in, e.g., a 5G system. The method in this application resolves the problem and saves overheads of sending a reference signal. The method includes: The terminal receives a beam information request sent by a location management device, where the beam information request is used to request the terminal to provide measurement information of a downlink beam. The terminal obtains beam information, where the beam information includes information about a reference signal that is sent by at least one network device and that is measured by the terminal.

Abstract: A physical downlink control channel transmission method and an apparatus. A terminal device obtains first indication information, where the first indication information indicates a time-frequency resource position of a first system information block 1 physical downlink control channel SIB1-PDCCH and an additional SIB1-PDCCH. The terminal device detects the first SIB1-PDCCH and the additional SIB1-PDCCH at the corresponding time-frequency resource position based on an indication of the first indication information, and obtains a system information block 1 SIB1 based on the detected first SIB1-PDCCH and the additional SIB1-PDCCH. In response to coverage of a SIB1-being is insufficient (for example, a higher frequency band), the first SIB1-PDCCH and the additional SIB1-PDCCH are jointly detected to improve a coverage capability of the SIB1-PDCCH, so that the terminal device obtains a SIB1 message and completes initial access.

Abstract: Paging methods and apparatuses applicable to a communication system are disclosed. One method includes: A network device sends first paging configuration information, where the first paging configuration information corresponds a first-type terminal device; and sends second paging configuration information, where the second paging configuration information corresponds to a second-type terminal device. A capability of the first-type terminal device is different from a capability of the second-type terminal device. The second-type terminal device receives the second paging configuration information; and receives paging downlink control information (DCI) based on the second paging configuration information.
