1. A method of enabling enhanced Management Plane (M-Plane) functions on the fronthaul interface between Open Radio Access Network Radio Unit (O-RU) and O-RAN Distributed Unit (O-DU) in an Open Radio Access Network (O-RAN)-compatible network, comprising:
identifying four subfields within 16-bit Extended Antenna Carrier Id (Eaxc-ID) field using a first set of four specified bitmasks, wherein the four subfields include DU_Port_ID bitmask, BandSector_ID bitmask, CC_ID bitmask, and RU_Port_ID bitmask; and
providing at least one additional bitmask to identify additional information regarding at least one individual bit within at least one of the BandSector_ID bitmask subfield and RU_Port_ID bitmask subfield;
wherein the at least one additional bitmask identifies at least one individual bit conveying additional information regarding at least one of band, sector, channel type, antenna port and data layer, and wherein the at least one additional bitmask is part of a second set of specified bitmasks including at least one of a band-bitmask, a sector-bitmask, a channel-type-bitmask, and a layer-antenna-port-bitmask.
