Discovery procedure signaling

A method for wireless communication, comprising:

• monitoring for a plurality of discovery preambles using a plurality of receive beams as part of a beam sweeping procedure;
• receiving a discovery preamble of the plurality of discovery preambles using a receive beam of the plurality of receive beams based at least in part on the monitoring, wherein the discovery preamble indicates an upcoming transmission of a discovery message;
• receiving the discovery message using the receive beam;
• and
• transmitting a signal in response to the discovery preamble or the discovery message using a transmit beam corresponding to the receive beam.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and instructions stored in the memory and executable by the processor to cause the apparatus to:
• generate a discovery preamble and a discovery message to broadcast in a device discovery procedure;
• transmit the discovery preamble using a transmit beam as part of a beam sweeping procedure, wherein the discovery preamble indicates an upcoming transmission of the discovery message;
• receive a signal in response to the discovery preamble or the discovery message;
• and
• transmit the discovery message based at least in part on the transmitting the discovery preamble.
