Reconfigurable intelligent surface (RIS) has been suggested to be a key 6G feature and was suggested to be considered as a study-item in both 3GPP Releases 18 and 19. However, in both releases, it has been decided not to continue with it as a study-item, and to leave it for possible future specification. In this paper, we present the rationale for such a decision. Particularly, we demonstrate the practical issues which may affect the feasibility or usefulness of RIS in cellular networks, and present open problems to be addressed before RIS can be used in practice. Moreover, we compare the performance of RIS with network-controlled repeater, the node with the most similar characteristics to RIS and which has been standardized in 3GPP Release 18. Finally, different simulations are presented to evaluate the performance of RIS-assisted networks.

  1. Parasitic MIMO Beamforming for Multi-Active Multi-Parasitic Antenna Arrays with Binary Control

    eess.SP 2026-07 conditional novelty 7.0 of 10

    A binary-switched parasitic antenna array with a quadratic current approximation achieves beamforming performance comparable to fully active arrays with significantly more RF chains.

  2. Joint Spatial Division and Multiplexing with Customized Orthogonal Group Channels in Multi-RIS-Assisted Systems

    cs.IT 2025-07 conditional novelty 5.0 of 10

    RISs placed at DFT directions of the base station enable a low-complexity JSDM pre-beamformer that approximately block-diagonalizes the multiuser channel and improves sum spectral efficiency in blocked coverage holes.

  3. Industrial Viewpoints on RAN Technologies for 6G

    cs.NI 2025-08 conditional novelty 3.0 of 10

    An industry-authored survey predicts 6G radio access will center on mid-band spectrum, evolved massive MIMO, AI/ML integration, OFDM-compatible waveforms, and native satellite support, explicitly labeled as speculation.
