1. A method for wireless communication at a first user equipment (UE) in a wireless communication network, the method comprising:
receiving a discovery signal initiation message from a second UE;
initiating discovery signal monitoring for a discovery signal monitoring duration based on receiving the discovery signal initiation message from the second UE; and
based on expiration of the discovery signal monitoring duration:
determining whether a number of other discovery signals from other UEs is less than a discovery signal transmission number threshold; and
transmitting a discovery signal to a third UE based on the number of other discovery signals from the other UEs is less than the discovery signal transmission number threshold.
