Abstract

This paper studies the sidelink positioning problem in a near-field wireless communication scenario with a single active reconfigurable intelligent surface (RIS). In this task, the positions of the transmitter and the receiver, as well as the clock bias between them are estimated jointly. To solve this problem, a time-orthogonal random codebook is adopted, which makes different channels separable. Then, we propose a coarse positioning method based on the sub-RIS division and the far-field approximation, followed by a least-squares-based refinement. The Cramér-Rao lower bound (CRLB) is derived, which verifies the efficiency of the proposed algorithms. The simulation studies reveal: (i) positioning performance is largely affected by the RIS size and the transmission power; (ii) the power allocation between the transmitter and the active RIS has an impact on the positioning accuracy, and there exists an optimal power allocation ratio that minimizes the CRLB.
