Abstract: Various communication systems may benefit from parallel preamble transmissions. In particular, communication systems of the long term evolution of the third generation partnership project may benefit from methods and systems for parallel preamble transmission in power limited situations. A method can include determining at a physical layer of a device that a predetermined condition has been met with respect to a power limited situation. The method can also include communicating an indication that the predetermined condition has been met to a higher layer of the device based on the determining that the predetermined condition has been met.
