Abstract: A User Equipment (UE) device operates to directly determine a target small cell for access or handover with the assistance of a macro cell network. The UE directly generates the connection and selects which small cell to access from among a subset of small cells chosen of a set of candidate small cells. The UE is provided dedicated assistance information from the evolved node B (eNB) or macro network device. The dedicated assistance information enables the UE to measure data from the candidate small cells within a heterogeneous network environment. The UE shares the measured data and connects directly to the selected small cell for an access or handover operation.

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. An eNB can provide indications to a UE for processing that indicate whether a transmission opportunity is on the same transmission opportunity as the UL grants or an external/outside transmission opportunity. 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.
