TL;DR: This work considers the cell-free massive multiple-input multiple-output (MIMO) downlink, where a very large number of distributed multiple-antenna access points (APs) serve many single-ant antenna users in the same time-frequency resource, and derives a closed-form expression for the spectral efficiency taking into account the effects of channel estimation errors and power control.

TL;DR: The localization algorithms are reclassified with a new perspective based on the mobility state of landmarks and unknown nodes, and a detailed analysis of the representative localization algorithms is presented.

TL;DR: This survey presents a review of the most successful MANAL algorithms, focusing on the achievements made in the past decade, and aims to become a starting point for researchers who are initiating their endeavors in MANAL research field.

TL;DR: The principles, performance metrics and key generation procedure are comprehensively surveyed, and methods for optimizing the performance of key generation are discussed.

TL;DR: A pivotal conclusion is reached that with increasing number of antennas at PBs, NPB offers a comparable secrecy performance to that of BPB but with a lower complexity.
