System and method for beam-based physical random-access

TL;DR: In this article, the authors proposed a method in a wireless device for performing random access to a network node, which comprises receiving a set of downlink beam-specific reference signals, BRS, from the network node and determining a preferred BRS based on the received signal power for each BRS.
