TL;DR: A novel handover mechanism to reduce unnecessary handovers in a mmWave cellular network by carefully deciding the next base station a user should handover to, so that the new user-BS connection after the handover can last as long as possible.

TL;DR: In this paper, the authors proposed a strategic NIS framework for backup reservation between a small/local network operator with limited resources and uncertain demands, and a more resourceful operator with excessive capacity.

TL;DR: In this paper, the authors proposed a bandwidth-efficient global zero-forcing precoding strategy for downlink transmission in cell-free massive MIMO systems by exploiting the physical structure of Rician fading channels, which decomposes a channel matrix into a line-of-sight (LoS) and a non-line-ofsight (NLoS), and then compresses them using a model-based method and a singular-valuedecomposition (SVD)-based method, respectively.

TL;DR: This study shows that NIS through backup reservation leads to both higher resource utilization and profits for operators, as well as higher service levels for end users, and the impact of competition intensity on the sharing decisions is highly dependent on the amount of potential redundant capacity.
