1. A method of wireless communication, comprising:receiving a first timing reference signal and a second timing reference signal at a local device, wherein the second timing reference signal includes an internal timing reference;
receiving a timing indication from a remote device, wherein the timing indication includes a value equaling to twice a propagation delay;
determining the propagation delay by dividing the value by 2;
calculating a timing offset by subtracting an arrival time of the first timing reference signal by the propagation delay;
adjusting the internal timing reference based on the timing offset; and
transmitting a message based on the adjusted internal timing reference.
