Abstract: Methods, systems, and devices for wireless communications are described. The described techniques relate to improved methods, systems, devices, and apparatuses that support power saving of wireless repeaters. Generally, the described techniques provide for wireless device (e.g., wireless repeater, wireless relay device, etc.) power savings in the absence of an attached (e.g., connected) user equipment (UE).
