1. A method for wireless communication at a receiving device, the method comprising:
receiving a discovery signal from a transmitting device, the discovery signal transmitted in a transmit direction using a directional transmission;
identifying, based at least in part on an angle of arrival associated with the discovery signal, the transmit direction;
selecting, based at least in part on the transmit direction and a location parameter associated with the transmitting device, an orthogonal metric to be used to recover the discovery signal; and
recovering the discovery signal using the selected orthogonal metric.
