Abstract: A method and an apparatus for timing measurement based positioning to minimize the number of scans is provided. The positioning method for a terminal includes estimating a temporary location of the terminal; analyzing characteristics of obstacles between the temporary location of the terminal and peripheral access points (APs) based on a pre-stored map on which the peripheral APs and the obstacles are indicated; calculating distances between the temporary location of the terminal and the peripheral APs based on the map; selecting at least three peripheral APs from among the peripheral APs according to at least one of the distances or the obstacle characteristics; generating timing measurement data with the at least three peripheral APs using identification information of the at least three peripheral APs; and estimating a current location of the terminal using the timing measurement data.

Abstract: A method and apparatus for cooperative positioning is disclosed herein. A method for cooperative positioning performed by a target device includes: scanning a beacon signal transmitted by at least one peripheral device; determining whether at least one peripheral device exist within a reference radius based on the beacon signal; when the at least one peripheral device is within the reference radius, transmitting a cooperative positioning request to the at least one peripheral device; receiving, in response to transmitting the cooperative positioning request, location of the at least one peripheral device and a degree of reliability for the location of the at least one peripheral device; and determining a location of the target device based on the location and the degree of reliability.
