1. An apparatus to be included in a wireless transmit and receive unit (“

  • WTRU”

    ), the apparatus comprising;

    processing circuitry to;

    determine a repetition level that corresponds to a number of repetitions associated with wireless communications between the WTRU and an access node;

    generate a random access preamble based on a logical root sequence index associated with the determined repetition level; and

    determine a resource of a physical random access channel (PRACH) for transmission of random access preambles associated with a repetition level equal to the determined repetition level, the resource determined from a first PRACH resource for transmission of random access preambles associated with a first repetition level and a second PRACH resource for transmission of random access preambles associated with a second repetition level, the first PRACH resource different than the second PRACH resource; and

    communications circuitry, communicatively coupled with the processing circuitry, to transmit the generated random access preamble to the access node using the determined resource of the PRACH.
