Low-Complexity Distance-Based Scheduling for Multi-User XL-MIMO Systems.

DBS categorizes users according to their equivalent distance to the antenna array. Such categorization effectively accounts for inter-user interference 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 2024-01-26T12:08:48Z 2024-01-26T12:08:48Z 2021-08-02 journal article J.
