    Abstract: This application provides an information indication method and apparatus for a non-terrestrial communication network. The method includes: A terminal receives first indication information, where the first indication information includes a bandwidth part BWP indication field, and the BWP indication field indicates a BWP identifier offset; the terminal determines a second bandwidth part identifier BWP_ID based on the BWP identifier offset, where the second BWP_ID corresponds to a target beam of the terminal; and the terminal switches to the target beam. The method extends indication of BWP identifiers on a premise of compatibility with indication based on conventional downlink control information DCI.

    Abstract: A communication method and a communication apparatus are provided. The method includes: A first device receives first information, determines a target TR pattern based on the first information, and sends information or demodulates received information based on the target TR pattern, where the target TR pattern is a sub-pattern of a longest TR pattern, and the longest TR pattern includes a set of sub-carriers used as reserved tones. The longest TR pattern may include a plurality of TR sub-patterns of different lengths. For example, a first TR pattern of a first length is a sub-pattern of the longest TR pattern, and a second TR pattern of a second length is also a subset of the longest TR pattern. The TR sub-patterns of different lengths may correspond to different carrier bandwidths or quantities of RBs.

    Abstract: Embodiments of this application disclose a communication method. The method includes: A terminal device sends a first message to a network device, where the first message includes one or more listening frequency indexes of one or more first tracking areas that are listened to by the terminal device within a first preset time period. The terminal device receives a second message including first registration area information from the network device. The first registration area information is determined based on the one or more listening frequency indexes. In the embodiments of this application, the accuracy of registration area information obtained by the terminal device can be improved, avoiding waste of communication resources caused by inaccurate registration area information received by the terminal device and improving communication resource utilization and practicality of the communication network.

    Abstract: A communication method and apparatus are provided. The method includes: A terminal device receives a first synchronization broadcast block (SSB) from a network device, where the first SSB indicates that a current network is in a coverage enhancement mode; then, the terminal device determines a target resource of first system information based on the first SSB; and finally, the terminal device receives the first system information from the network device based on the target resource. In the method, transmission of a plurality of repeated SSBs can be supported in the network coverage enhancement mode, and a quantity of transmitted system information blocks 1 (SIB1s) can be reduced, to reduce system overheads.

    CPC classification number: G06N3/098

    Abstract: This application provides a model training method and a related apparatus. In the method, a second communication apparatus receives a first neural network parameter of a first communication apparatus, and sends first indication information to the first communication apparatus when a correlation coefficient between the first neural network parameter and a second neural network parameter of the second communication apparatus is less than a first threshold. The first indication information indicates that the second communication apparatus is to participate in training of a first neural network model of the first communication apparatus. That the correlation coefficient between the first neural network parameter and the second neural network parameter is less than the first threshold indicates that the second neural network parameter makes a great contribution to convergence of the first neural network model.

    Abstract: Embodiments of this application relate to the field of communication technologies, and provide a timing offset parameter update method, a device, and a system, to help reduce signaling overheads when a terminal device updates a value of a timing offset parameter. The method includes: A terminal device obtains a timing advance adjustment variation corresponding to the terminal device, where the timing advance adjustment variation is a difference between a timing advance adjustment amount currently used by the terminal device and a timing advance adjustment amount used at a previous moment. The terminal device determines whether an absolute value of the timing advance adjustment variation is greater than or equal to a first threshold. If the absolute value is greater than or equal to the first threshold, the terminal device sends, to a network device, first indication information used to indicate an update regularity of a timing offset parameter.
