Upper bound on capacity of 5G mmWave cellular with multi-connectivity capabilities

Outage events caused by dynamic blockage of a radio signal propagation path are one of the key challenges in 5G millimetre-wave (mmWave) cellular networks. To mitigate them, Third Generation Partnership Project standardisation has recently ratified multi-connectivity techniques aiming to enable user connectivity to several base stations simultaneously, while switching between them whenever the currently active connection becomes blocked. A closed-form upper bound on the probability density function of the respective system capacity in a random field of moving blockers is obtained.
