1. An apparatus configured for wireless communication, comprising: one or more memories comprising processor-executable instructions; and one or more processors configured to execute the processor-executable instructions and cause the apparatus to:
identify first intelligent reflecting surface (IRS) reflection centers for one or more IRSs as a center of each of the one or more IRSs;
estimate a first position of the apparatus based on, at least, the first IRS reflection centers for the one or more IRSs; and
estimate a second position of the apparatus in an iterative manner until at least one of: a change in position of the apparatus based on the second position of the apparatus and a previously estimated position of the apparatus is less than a first threshold, or a change in location of each respective IRS reflection center for each respective IRS of the one or more IRSs is less than a second threshold, wherein in order to estimate the second position of the apparatus in the iterative manner, the one or more processors are further configured to cause the apparatus to:
identify second IRS reflection centers for the one or more IRSs using the previously estimated position of the apparatus and a virtual focal point for each respective IRS of the one or more IRSs; and
estimate the second position of the apparatus based on, at least, the second IRS reflection centers for the one or more IRSs.
