1. A method for wireless communication at a first user equipment (UE), comprising:
receiving, from a second UE, a first sidelink synchronization signal at a first transmission-reception point (TRP) and a second TRP different from the first TRP;
performing a first set of measurements on the first sidelink synchronization signal received at the first TRP and a second set of measurements on the first sidelink synchronization signal received at the second TRP;
initiating one or more timers based at least in part on determining that the first set of measurements, the second set of measurements, or both, satisfy one or more measurement thresholds; and
transmitting, to a third UE, a second sidelink synchronization signal based at least in part on determining an expiration of the one or more timers and based at least in part on the first set of measurements, the second set of measurements, or both, satisfying the one or more measurement thresholds.
