    Abstract: This application provides a calibration method and apparatus. The method includes: determining first channel state information and second channel state information, where the first channel state information is obtained through prediction via a first channel prediction model, and the second channel state information is determined based on channel estimation on a downlink signal from an access network device; and sending first information to the access network device if a difference metric value between the first channel state information and the second channel state information is greater than or equal to a first threshold, where the first information indicates the second channel state information.

    Abstract: A random access method, an apparatus, and a system are disclosed. A terminal device receives, from a network device, information about a PRACH resource set and information about one or more PUSCH resources associated with each PRACH resource in the PRACH resource set. If a first PUSCH resource associated with a valid first PRACH resource in the PRACH resource set is valid, the terminal device sends a first preamble sequence to the network device on the first PRACH resource, and sends uplink data to the network device on the first PUSCH resource. The network device receives the first preamble sequence from the terminal device on the first PRACH resource, and receives the uplink data from the terminal device on the first PUSCH resource. The first preamble sequence is a preamble sequence set associated with the first PUSCH resource.
