TL;DR: The present paper analyzes the paradigm of providing streaming services over HSDPA and finds that the operation of the packet scheduling functionality completely determines the node B queuing streaming packets prior to their transmission through the radio interface, and therefore the scheduler plays a key role in the satisfaction of the delay jitter constraint.

TL;DR: Findings show that GF procedures are capable of providing significant lower latency than GB at the reliability level of 1-e-5, even at considerable network loads, as a function of the load using extensive and detailed system level simulations.

TL;DR: Fundamental features such as optimized short frame structure, multi-antenna technologies, interference rejection, rank adaptation and dynamic scheduling of uplink/downlink transmission are discussed, along with the design of a novel flexible waveform and energy-saving enablers.

TL;DR: In this article, the performance of the M/spl times/N concept is evaluated in terms of the number of independent parallel channels, diversity gain and total capacity in an outdoor to indoor microcellular environment.

TL;DR: Analytical results show the benefits of grant-free transmission with respect to the traditional grant-based approach for a tight latency constraint, and a high-order receive diversity is beneficial to leverage the MRC gain and enables the possibility of achieving the 10−5 outage probability target set for ultra-reliable low-latency communication services.
