Abstract: Embodiments of this application belong to the field of communication technologies. In the method, a first node may send first measurement configuration information to a second node, where the first measurement configuration information indicates to measure synchronization information of a third node on a first channel. Further, the second node may obtain the synchronization information, and the first node receives the synchronization information from the second node, where the synchronization information may indicate one or more of the following information of the third node: time synchronization information, frequency synchronization information, synchronization communication domain set information, RSRP, RSRQ, SINR, or RSSI. In this way, time-frequency synchronization between different nodes in a communication system can be implemented, interference between the different nodes can be effectively reduced, and system communication performance can be improved.

Abstract: A method for creating a network simulation platform that has a first black box model, includes: obtaining a candidate network performance indicator and feature information related to the candidate network performance indicator, where the feature information related to the candidate network performance indicator refers to a part or all of feature information needed to obtain the candidate network performance indicator; and training a machine learning model to obtain the first black box model, where an output parameter of the first black box model is the candidate network performance indicator, input parameters of the first black box model are the feature information related to the candidate network performance indicator, and the first black box model is used to simulate the candidate network performance indicator. The solutions provided help reduce simulation complexity and are applicable to large-scale network simulation.

Abstract: An automatic driving track obtaining method and apparatus are provided. The method includes: obtaining a driving style coefficient of a driver of a vehicle A (S101); calculating a cost function of the driver of the vehicle A based on the driving style coefficient of the driver of the vehicle A (S102), where the cost function is used to represent costs paid when the vehicle A travels from an initial node to a current node in a driving track of the vehicle A; and obtaining the driving track of the vehicle A on a first three-dimensional spatial-temporal map through calculation according to the cost function (S103). The driving track obtained by using the method and the apparatus can match driving styles of all drivers. This improves driver satisfaction on the driving track, and lessens a running-in period in which the driver performs automatic driving.
