GENERATION OF RANDOM ACCESS PREAMBLES

摘要

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.

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 to or from the WTRU, to determine a resource associated with the repetition level for a random access procedure based on the determined repetition level, and to generate a random access preamble; and communications circuitry, communicatively coupled with the processing circuitry, to transmit the generated random access preamble to an access node using a physical random access channel associated with the random access procedure based on the determined resource.
