Specifically, a visibility region (VR)-aware scheduling strategy is proposed, allowing the superposition of near and far-field users through both partial and full NOMA approaches. Low-complexity, VR-aware detection techniques are developed for each NOMA configuration. In this design, nearfield users with distinct, non-overlapping VRs share frequency resources with a far-field user occupying a larger VR, with the proposed detection techniques ensuring effective multiuser separation. This approach enhances system capacity and supports massive connectivity within the XL-MIMO framework. Simulations demonstrate significant gains in bit error rate (BER) and SE across all users, all while maintaining low the complexity.
