Embodiments described herein relate generally to a random procedure between wireless transmit/receive units (“WTRUs”) and access nodes. A WTRU may be adapted to determine a repetition level that corresponds to a number of repetitions associated with communication with the access node. The WTRU may then determine at least one of a resource and/or a logical root sequence index associated with the random access procedure. The WTRU may transmit a random access preamble based on the resource and/or a logical root sequence index. The access node may be adapted to determine a repetition level associated with the WTRU based on the random access procedure. Other embodiments may be described and/or claimed.
