Method and system of leased radio unit (ru) and spectrum architecture for reducing latency in access to operator resources

A data processing system to implement a wireless network supporting communications by user equipment (UE), the data processing system comprising:

• a plurality of distributed units (DUs) each associated with at least one of a plurality of cell sites;
• a data processing system associated with a host operator of the wireless network, the data processing system configured to:
• map each of a plurality of Bandwidths Parts (BWPs) available from each of the plurality of DUs to one of a plurality of public land mobile network identifications (PLMN-IDs), wherein each of the plurality of PLMN-IDs is associated with at least one operator of a set of different operators all sharing access to the wireless network;
• associate each of the PLMN-IDs with a different physical random access channel (PRACH) occasion, wherein each PRACH occasion is available from at least one of the DUs for uplink (UL) transmission from user equipment (UE) associated with the PLMN-ID of the PRACH;
• and
• identify, for each of the DUs, each PRACH occasion available from the DU based on each PLMN-ID of the set of PLMN-IDs to thereby enable the UE to access the NR cell site using the PRACH occasion associated with the PLMN-ID that is associated with the UE, and to thereafter communicate with the cell cite via the BWPs that are allocated to the operator associated with the PLMN-ID of the PRACH.
