Abstract: A positioning method includes a first device performs a target operation, to assist a first terminal in positioning. The target operation includes transmitting a target message, transmitting a first SL-PRS, or selecting a target first resource. The target first resource is used for transmitting the first SL-PRS and/or transmitting the target message. The target message includes a positioning request, positioning assistance data, or first resource configuration information. The first resource configuration information is used for configuring at least one first resource. The target first resource is one or more resources in the at least one first resource. The first SL-PRS is used for determining location information of the first terminal and/or second terminal, and/or SL-PRS measurement information. The second terminal is a peer terminal that performs SL communication or SL positioning with the first terminal.
