    Abstract: A method and apparatus for offloading backhaul traffic are disclosed. A first base station may detect a condition triggering backhaul traffic offloading for a wireless transmit/receive unit (WTRU). The first base station may establish a wireless connection with a second base station, and offload at least one bearer of the WTRU onto the second base station via the wireless connection. The first base station may be a macro-cell base station and the second base station may be a femto-cell base station having a wired connection to Internet and a mobile operator core network. The first or second base station may include a relay functionality and act as a relay between the WTRU and the other base station. The backhaul link may be established using a Uu, Un, X2 interface or any other interface over a licensed or license-exempt frequency, a TV white space frequency, etc.

    Abstract: A method and apparatus are described for integrating third generation partnership project (3GPP) radio access network and an Institute of Electrical and Electronics Engineers (IEEE) 802.11 radio access technologies (RATs). This may be done at a medium access control (MAC) layer or below the MAC layer. For example, a wireless transmit/receive unit (WTRU) for multiple radio access technology (RAT) integration includes a 3GPP RAT including a radio resource control (RRC) entity, an IEEE 802.11 RAT including a medium access control (MAC) management entity, and a session management entity (SME) for mapping between the RRC entity and the MAC management entity. Combined, hybrid and split versions of logical channel prioritization (LCP) are described. The features of an LTE access stratum-service management entity (AS-SME) are also described.

    Abstract: Embodiments contemplate Small Cell Enhancements such as PDCP Placement and impact on control and data plane procedures. Embodiments contemplate small-cell enhancements such as they relate to dual-connectivity scenarios. Different architecture models and their impact on procedural aspects are contemplated. Different RAN, protocol stack and radio bearer (RB) architectures along with their implications are described. These architectures may be applicable to one or more of control plane that may terminate at the macro. Also, a small-cell that may be capable of supporting RLC modes and/or that may be capable of supporting MAC functionality is contemplated. A small-cell may be capable of supporting bidirectional physical channels. Also, there could be an aggregation point (either at the macro eNB or at a different physical or logical RAN node) for S1-U interface termination. The Small Cell eNB (SCeNB) could be in control of the Macro eNB.

    Abstract: A method and apparatus for improving and performing mmW beam tracking is disclosed. Localization methods to improve prediction of the position of a WTRU are described, which may allow a millimeter wave base station (mB) to appropriately select a modified beam and to perform more efficient handover. WTRUs may report directional signal strength measurements to mBs, which may then be used to generate a directional radio environment map (DREM) for use in identifying secondary links to use when a primary link fails. Additional localization techniques using internal/external information for prediction are described. Historical data use and the use of data obtained from mB-mB cooperation including feedback information and reference signaling information are also described. Methods for beam tracking for directional relays and initial beam training optimization are described as well. Finally, WTRU localization precision improvement, beamwidth adaptation, and assisted beam tracking and handover methods are also described.
