Certain embodiments disclose a method in a wireless device. The wireless device receives a location of a time and/or frequency resource of a first Physical Random Access Channel (PRACH) from a network node. The wireless device receives a location of a time and/or frequency resource of a second PRACH. Furthermore, the wireless device transmits a first random access attempt via the first PRACH and transmits a second random access attempt via the second PRACH. The first PRACH and the second PRACH each have an associated preamble, and wherein the second PRACH preamble has a different length than the first PRACH preamble.
