Abstract: A neural network adjustment method and apparatus. The neural network adjustment method relates to a first neural network and a second neural network. The method includes: whether a currently used neural network needs to be updated is first determined; and if the currently used neural network needs to be updated, a first device may autonomously complete the update or indicate a second device to complete the update. In other words, a more appropriate neural network may be obtained by updating a neural network in an AI model, to improve precision of information transmission based on the AI model.

Abstract: This application provides an uplink reference signal sending method and apparatus, a base station, and user equipment (UE). The method includes: configuring, by the base station, M pieces of uplink reference signal resource information for the UE; and sending, by the base station, the M pieces of uplink reference signal resource information to the UE, so that the UE sends uplink reference signals based on different uplink reference signal resource information with different beamforming gains. A path loss is compensated for by using a beamforming technology. In addition, the base station configures the M pieces of uplink reference signal resource information for the user equipment UE, so that the UE sends the uplink reference signals by using different relatively uplink reference signal resource information based on different beamforming gains. Therefore, uplink reference signal sending efficiency is improved.

Abstract: A channel information reporting method and apparatus and a system are used to improve adaptive performance of a link. A first device includes: a receiving module, configured to receive a reference signal from a second device; a processing module, configured to: perform channel estimation based on the reference signal to obtain a channel matrix, decompose the channel matrix to obtain an unquantized precoding matrix, and generate channel information used to describe the unquantized precoding matrix; and a sending module, configured to send the channel information used to describe the unquantized precoding matrix to the second device. The second device sends the channel information used to describe the unquantized precoding matrix. Therefore, a quantization error is avoided, so that a precoding matrix obtained by the first device is more accurate, thereby effectively improving the adaptive performance of the link.
