Abstract: Embodiments of an Evolved Node-B (eNB), User Equipment (UE) and methods for directional communication are generally described herein. The eNB may transmit, during a downlink sub-frame, a first beam refinement training signal and an uplink scheduling block to a first UE according to a downlink transmission direction from the eNB to the first UE. The eNB 104 may further transmit, during the downlink sub-frame, a second beam refinement training signal and a downlink scheduling block to a second UE according to a downlink transmission direction from the eNB to the second UE. The uplink scheduling block may indicate scheduled uplink resources for a scheduled uplink transmission by the first UE and the downlink scheduling block may indicate scheduled downlink resources for a scheduled downlink transmission to the second UE.
