Abstract: Wireless communications systems and methods related to mechanisms to provide physical sidelink feedback channel (PSFCH) negotiation during sidelink connection establishment. A first UE may determine one or more conditions for PSFCH communications via the sidelink session(s) with the second UE. If the second UE accepts the conditions provided, the first and second UEs complete the sidelink connection. Further, while the first UE has a sidelink communication session with the second UE, a third UE may initiate another sidelink connection with the first UE. The first UE may compare the priority of the proposed sidelink connection with the priority of the ongoing sidelink communication session with the second UE. If the second UE's priority is greater, the first UE will maintain the second UE's status. If less, the first UE may engage in a renegotiation with second UE for the ongoing sidelink communication session to update their PSFCH conditions.
