It is expected this specification will be further enriched over the course of Release-17 efforts, including further beam operation-related enhancements. 4.1.3.3 Release-17 and Beyond: Where We Are Going While the conceptual and operational model of beamforming antenna subsystem beams Release-15 is predominantly single TxRx point-based, in Release-16 (and more SO on into upcoming Release-17 and beyond) there is a shift to support a multi-point, networked system-oriented conceptual model of multiple coordinated TxRx points. To a degree, the Release-15 beam concept is a useful transition and stopgap: the approach is somewhat to just treat beams like "narrower and more dynamic cell sectors" for the sake of RRM link monitoring. This initial similarity allowed Release-15 to be standardized and fielded faster as well as to help operators and network equipment vendors to minimize immediate redesign of existing 4G-based management systems and technical operations processes/approaches. That said, supporting the emerging multi-point TxRx points capability will greatly benefit from, if not demand, better and more explicit spatial/beam resource management. For instance, gNBs and other complimentary controllers such as those from the O-RAN Alliance will need to have a more explicit, precise, and low-latency knowledge of multi- beam multi-point antenna TxRx point relationships. In keeping with both O-RAN and 3GPP advanced beamforming antenna system modeling, this will include increased usage of a global coordinate system in which to orient the antennas' individual local coordinate systems. To deliver these performance attributes, beamforming antenna subsystem interface control/monitoring will need to be distributed over higher performance fronthaul to enable finer multi-point coordination capabilities in time and space. Furthermore, we expect t
