Abstract: A positioning method and apparatus. A location management network element sends first indication information to a network device, where the first indication information is useable by the network device to measure a signal that is sent by a terminal device and that is reflected by a reflection panel. After receiving the first indication information, the network device measures the signal reflected by the reflection panel, and reports a measurement result to the location management network element. The location management network element determines a location of the terminal device based on location information of the network device, location information of the reflection panel, and the measurement result. In response to a line-of-sight (LOS) path between the terminal device and the network device being blocked, a signal on the LOS path cannot be directly transmitted and measured.

Abstract: Embodiments of this application provide a synchronization signal block transmission method and a communications apparatus. The method includes: A network device sends an SSB to a terminal device in a resource position of the SSB. Correspondingly, the terminal device receives the SSB. In this process, a symbol included in the resource position of the SSB does not overlap with an uplink symbol in a plurality of self-contained slot structures as much as possible. This method can reduce a probability that the symbol included in the resource position of the SSB conflicts with an uplink symbol in as many self-contained slot structures as possible, to avoid cross interference, and therefore can support reliable transmission in as many self-contained slot structures as possible.

Abstract: A first access network device receives an addition request message from a second access network device. The first access network device determines a third uplink carrier used by a terminal to send a preamble to the first access network device, and sends an addition request acknowledgement message to the second access network device. The addition request acknowledgement message includes carrier indication information. The carrier indication information indicates the third uplink carrier. The third uplink carrier is at least one of the first uplink carrier or a second uplink carrier. The second uplink carrier and the first uplink carrier belong to a same cell of the first access network device and the second uplink carrier is a supplementary uplink carrier.
