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 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: A sensing communication method and an apparatus that may resolve a problem of mutual interference caused when different readers use a same resource to communicate with a tag. A network device schedules a sensing resource of the reader to the reader. The reader sends a sensing signal based on the scheduled sensing resource, and senses a sensing signal of another reader, to obtain a sensing result. The reader sends the sensing result. The reader receives information for determining a resource for communication between the reader and the tag. The reader uses the communication resource to communicate with the tag. The sensing resource is scheduled by the network device, so that communication efficiency between the reader and the tag can be improved.

Abstract: A communication method and apparatus to reduce a waiting latency in a retransmission process. A terminal device receives a first PDSCH from a network device. In response to failing to decode data carried on the first PDSCH, the terminal device sends an SRS to the network device on a first time-frequency resource. In response to the network device not receiving feedback information of the first PDSCH, or receiving feedback information of the first PDSCH that is a NACK, the network device retransmits the first PDSCH based on a result of measuring the SRS. After determining that the first PDSCH fails to be decoded, the terminal device directly sends the SRS to the network device by using the first time-frequency resource.

Abstract: This present disclosure discloses example communication methods and communications apparatuses. One example communication method includes a terminal device determining a first offset of a first power class and a second offset of the first power class when a power class of the terminal device is the first power class. A compensation amount of the first power class is determined based on the first offset and the second offset. A determination as to whether to camp on a first cell is made based on the second offset and the compensation amount of the first power class.

Abstract: Embodiments of this application provide a method for transmitting positioning assistance data and a device. The method includes: receiving, by a network device, at least one positioning assistance data message sent by a positioning server, where the at least one positioning assistance data message is used to carry positioning assistance data; and broadcasting, by the network device, a system message to a terminal device, where the system message is used by the terminal device to obtain the positioning assistance data. According to the embodiments of this application, the network device broadcasts the system message to broadcast the positioning assistance data. In this way, a problem of low efficiency of transmitting existing centralized positioning assistance data can be resolved, and a problem in the prior art that a positioning server needs to perform signaling communication with each terminal device in a unicast transmission scenario can be avoided, thereby reducing signaling overheads.
