TL;DR: The state of the art in mm-wave V2V channel measurements and modeling is reviewed, recent directional V2v channel measurements performed in the 60-GHz band are described, and future challenges to be addressed are discussed.

TL;DR: The main conclusion of this paper is that V2V communication will be possible in high (millimeter-wave) frequencies, even in the case of blockage by other vehicles.

TL;DR: The analysis indicates that not only more spectrum and more efficient spectrum usage concepts are required but that the broader range of application requirements will in addition result in new challenges on spectrum engineering with respect to guaranteeing coexistence, compatibility, and coverage.

TL;DR: The main properties of the indoor radio channel at 70 GHz, including angular and temporal dispersion as well as an assessment of the major interaction mechanisms are investigated in this study by means of UWB directional measurements and ray tracing simulations in a reference, small-indoor office environment.

TL;DR: The proposed concept considers the flexible air-interface being developed for 5G and can support coordinated inter-operator spectrum sharing in various scenarios, including mutual renting, spectrum spot market, co-primary sharing, licensed shared access (LSA), secondary horizontal sharing etc.
