    Low-Complexity Distance-Based Scheduling for Multi-User XL-MIMO Systems
    (IEEE, 2021) González-Coma, José P.; López-Martínez, F.J.; Castedo, Luis
    We introduce Distance-Based Scheduling (DBS), a new technique for user selection in downlink multi-user commu nications with extra-large (XL) antenna arrays. DBS categorizes users according to their equivalent distance to the antenna array. Such categorization effectively accounts for inter-user interfer ence while largely reducing the computational burden. Results show that (i) DBS achieves the same performance as the reference zero-forcing beamforming scheme with a lower complexity; (ii) a simplified version of DBS achieves a similar performance when realistic spherical-wavefront (SW) propagation features are considered; (iii) SW propagation brings additional degrees of freedom, which allows for increasing the number of served users.
