1. A method for providing Random Access Channel (RACH) response preamble prioritization, the method comprising:
receiving, from a RACH receiver at a Preamble Prioritization Element (PPE), a list of detected preambles from a plurality of User Equipment (UE) devices, the preambles having a configured priority for different preamble groups;
providing, by the PPE, an ordered prioritized list of the detected preambles;
forwarding, by the PPE to a RACH response element, a predetermined number of detected preambles from the ordered prioritized list; and
sending a first Random Access Response (RAR) message to a UE that sent a dedicated preamble based on the ordered prioritized list.
