Abstract
Technology to achieve uplink synchronization with a mmWave enhanced Node B (eNB) is disclosed. In an example, a user equipment (UE) can include circuitry configured to: receive selected random access (RA) parameters from an anchor eNB for uplink synchronization; identify a transmission direction for communication with the mmWave eNB based on a downlink synchronization of the UE with the mmWave eNB; and communicate a random access channel (RACH) transmission in the identified transmission direction for uplink synchronization of time, frequency, and beam direction with the mmWave eNB.
