A method for reporting positioning measurement information, a terminal, and a network device are provided. The method includes: receiving first configuration information from a network device; and reporting a measurement result of a beam group based on the first configuration information, where the beam group is used to transmit a positioning reference signal PRS, and the beam group includes N beams determined by reference signal received power RSRP or time of arrival TOA, where N is a positive integer, the N beams are beams in a first cell, and the first cell is one of cells participating in positioning.
