Abstract: This application discloses a data receiving method, which may be applied to Internet of Vehicles, for example, V2X, LTE-V, and V2V. A first terminal apparatus may receive first control information from a second terminal apparatus, then receive second control information from the second terminal apparatus based on the first control information, and further receive, based on the first control information and the second control information, data sent by the second terminal apparatus. Therefore, the second control information and the data can be received after blind detection is performed on the first control information for a relatively small quantity of times, thereby improving efficiency of receiving the second control information and the data.

Abstract: A network slice selection method, a radio access device, and a terminal, where the method includes obtaining, by a radio access network (RAN) device, network slice information, sending, by the RAN device, a first message to a terminal, where the first message includes the network slice information, receiving, by the RAN device, a first access request message from the terminal after the terminal selects, based on the network slice information, first attribute information of a first network slice to be accessed by the terminal, and selecting, by the RAN device based on the first attribute information of the first network slice, a second network slice to be accessed by the terminal. The method enables an operator to flexibly configure a network slice, and reduces a communication latency and signaling overheads in a process in which a terminal selects a network slice.
