The method includes: An access network device sends DCI for a paging message to a terminal device, where the DCI includes scheduling information for downlink data. The access network device further sends first indication information included in the paging message to the terminal device, wherein the first indication information indicates that first downlink data corresponds to the terminal device. Therefore, when determining that there is downlink data to arrive, the terminal device determines a time-frequency location of the downlink data based on the scheduling information that is for the downlink data and that is in the DCI, and then receives the downlink data at the time-frequency location. According to the method and the apparatus provided in this application, a small amount of downlink data is transmitted, resource utilization is improved, and power consumption of the terminal device is reduced.

The second access network device determines information about a first-time active BWP and/or BWP configuration information of the terminal device on the second access network device based on the first indication information. The method may be used to enable the second access network device to determine the appropriate information about the first-time active BWP and/or the appropriate BWP configuration information of the terminal device on the second access network device. In this way, service interruption caused by switching of an active BWP is reduced, and/or service interruption caused by changing of a BWP configuration is reduced.
