ESTABLISHING RADIO BEARERS ON MILLIMETER WAVE FREQUENCIES FOR DEVICE-TO-DEVICE COMMUNICATIONS

Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) establishes a radio resource control (RRC) connection for a communication session with a second UE, establishes a signaling radio bearer (SRB) for the communication session with the second UE on a first frequency band, sends, to the second UE over the SRB on the first frequency band, a first RRC message to establish a data radio bearer (DRB) for the communication session on a second frequency band, the first RRC message including one or more parameters for establishing the DRB on the second frequency band, and configures the DRB on the second frequency band based on the one or more parameters in the first RRC message and/or a device-to-device discovery procedure performed in the first frequency band.
