摘要
Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) performs a limited beam sweep of one or more transmit beams on a second frequency band in an estimated direction from the first UE to the second UE, wherein the estimated direction is based on one or more parameters received over a previously established signaling radio bearer (SRB) on a first frequency band and/or a device-to-device discovery procedure performed on the first frequency band, receives, over the SRB, a confirmation that a data radio bearer (DRB) has been established on the second frequency band with at least one transmit beam of the one or more transmit beams, and sends, to the second UE, a data flow over the DRB on the second frequency band using the at least one transmit beam.
