TL;DR: This paper proposes a directional cell discovery procedure where base stations periodically transmit synchronization signals, potentially in time-varying random directions, to scan the angular space and reveals two key findings: 1) digital beamforming can significantly outperform analog beamforming even whendigital beamforming uses very low quantization to compensate for the additional power requirements and 2) omnidirectional transmissions of the synchronization signals from the base station generally outperform random directional scanning.

TL;DR: In this article, a survey collects and analyzes recent papers leveraging context information to forecast the evolution of network conditions and, in turn, to improve network performance, identifying the main prediction and optimization tools adopted in this body of work and link them with objectives and constraints of the typical applications and scenarios.

TL;DR: This analysis demonstrates significant benefits of low-resolution fully digital architectures in comparison with single stream analog beamforming in next-generation mmWave bands.

TL;DR: A two-tier 360 video streaming framework with prioritized buffer control is proposed to effectively accommodate the dynamics in both network bandwidth and viewing direction, and it is demonstrated that the proposed framework can significantly outperform the conventional360 video streaming solutions.

TL;DR: It is shown that the use of digital beamforming for initial access will expedite the whole process significantly and it is argued that low quantization digitalbeamforming can more than compensate for high power consumption.
