Abstract: An apparatus is configured to be employed within one or more user equipment (UE). The apparatus includes control circuitry and a transceiver. The control circuitry is configured to generate a physical random access channel (PRACH), wherein the PRACH includes a preamble for PRACH transmission using a license assisted access (LAA) secondary cell.

Abstract: Techniques for mobile communication in an unlicensed frequency band are discussed. A network device (e.g., an evolved NodeB, or other cell network device) can generate a listen before talk (LBT) protocol in order to determine whether an unlicensed carrier of a secondary cell device is idle or busy. The LBT protocol can be generated as a one shot LBT within a two symbol duration of a potential downlink (DL) transmission burst, or multiple times within the two symbol duration. In response to an idle state detection, a discovery reference signal (DRS) can be transmitted. In response to the LBT protocol and the DRS transmission being misaligned, a reservation signal can be generated to reserve the unlicensed carrier for the DL transmission.

Abstract: A network device (e.g., an evolved Node B (eNB), user equipment (UE) or the like) can operate to enable scheduling UL transmissions on transmission opportunities outside of the UL grants or for multi-carrier UL scheduling. A communication component of the device can operate to process or generate communications on an unlicensed band or a licensed band in response to UL grants and indications provided via a DL transmission for scheduling.

The indications can further trigger an listen-before-talk (LBT) protocol, which can vary between a category 4 LBT or a single LBT interval that is shorter than the category 4 LBT, depending on the indication.
