1. A positioning apparatus, comprising:
at least one processor;
a transceiver; and
one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
send, by the transceiver, a positioning measurement request to a positioning measurement network element, wherein the positioning measurement request is used to request the positioning measurement network element to feed back channel state information of a terminal device, wherein the positioning measurement request comprises antenna port pair configuration information that indicates an antenna port pair whose channel state needs to be reported;
receive, by the transceiver, a positioning measurement response from the positioning measurement network element, wherein the positioning measurement response comprises the channel state information of the terminal device, and the positioning measurement response comprises antenna port pair indication information that indicates the antenna port pair corresponding to the channel state information of the terminal device; and
determine a location of the terminal device based on the channel state information of the terminal device.
