Abstract: A grant-free transmission method is provided. Under the method, a target time-frequency resource used for grant-free transmission can be determined by a terminal device from a plurality of time-frequency resources. A sequence corresponding to the target time-frequency resource can be determined by the terminal device based on information about the target time-frequency resource and a correspondence between a time-frequency resource and a sequence. The grant-free transmission with a network device can be performed on the target time-frequency resource based on the sequence corresponding to the target time-frequency resource. In this way, the network device can effectively determine, based on the sequence sent by the terminal device, a time-frequency resource used by the terminal device for the grant-free transmission.

Abstract: A communication method and an apparatus. A terminal device (or an access network device) obtains a channel feature through inference by using a channel feature extraction model, where the channel feature corresponds to a channel between the terminal device and the access network device. The terminal device (or the access network device) sends the channel feature to a location management function LMF. The LMF obtains, based on the channel feature, positioning information of the terminal device through inference by using a positioning information obtaining model. The LMF may determine location information of the terminal device based on the positioning information. An artificial intelligence model may be used to implement positioning or assist in implementing positioning of the terminal device.

Abstract: A communication method and apparatus are provided. The method includes: obtaining N pieces of training data, where for one of the N pieces of training data, the training data corresponds to one piece of mark information, and the mark information indicates an attribute of the training data; and sending indication information to a terminal device, where the indication information indicates information about M artificial intelligence models, the artificial intelligence model is trained based on X pieces of training data in the N pieces of training data, and the X pieces of training data are determined based on the mark information. When the N pieces of training data are obtained, the N pieces of training data may be used for constructing training data corresponding to different mark information, to train the M artificial intelligence models or more artificial intelligence models, so that scenario-based artificial intelligence model training can be implemented.

Abstract: This application relates to a channel information feedback method, a channel information recovery method and an apparatus. In an example method, a terminal device receives a first reference signal from a network device. The terminal device obtains a first channel state matrix based on the first reference signal. The terminal device performs sampling on the first channel state matrix based on a first sparse pattern, to obtain a sparse channel state matrix, where the first sparse pattern is configured by the network device, and the first sparse pattern is used for performing sampling on at least one dimension of the first channel state matrix. The terminal device sends first channel information to the network device, where the first channel information indicates the sparse channel state matrix.
