Abstract
Disclosed are techniques for determining locations of reference nodes. In an aspect, an apparatus transmits a request to a first reference node to perform a first round-trip-time (RTT) procedure with a second reference node, determines a first distance between the first reference node and the second reference node based on the RTT procedure, determines relative locations of the first and second reference nodes with respect to each other, and determines absolute locations of the first and second reference nodes from their relative locations based on at least one of the first and second reference nodes having a known absolute location and at least one known angle-of-arrival (AoA) or angle-of-departure (AoD) of at least one reference signal.
