Certain aspects of the present disclosure provide a method for wireless communications by a transmitter user equipment (UE). The method may include receiving (e.g., from a network entity) a configuration of a first resource pool associated with a second resource pool. The first resource pool includes physical sidelink feedback channel (PSFCH) resources for hybrid automatic repeat request (HARQ) responses for physical sidelink shared channel (PSSCH) transmissions in the second resource pool. The method further includes transmitting (e.g., to a receiver UE) a PSSCH on a resource in the second resource pool and a request for a HARQ response for the PSSCH from a PSFCH resource in the first resource pool. The method further includes receiving (e.g., from the receiver UE) the HARQ response over the PSFCH resource (e.g., in response to the PSSCH).
