Abstract: A method for acquiring and applying offload area information for offloading a wireless transmit/receive unit (WTRU) to a small cell in a different frequency layer is disclosed. The WTRU may enter a region or a macro cell and receive offload area information of the region in which a small cell in the vicinity of the macro cell is located. The offload area information may include at least one of a global positioning system (GPS) coordinate, a radius over which the area extends with respect to the GPS coordinate, a list of position reference signals (PRS), a cell identity or a list of cell identities, a frequency on which the small cell is located, and a radio access technology (RAT) of the corresponding cell. The offload information may be received in a system information block (SIB), dedicated signaling, or any other radio signal. The WTRU may perform measurements to determine the location of the WTRU and to determine whether it has entered any offload areas. Upon a determination that the offload area information is no longer valid, the WTRU may delete the offload area information.

Abstract: A method and apparatus may be used to enable reception of a downlink (DL) shared channel in a cooperative multipoint transmission (CoMP). The method and apparatus may determine whether CoMP is applied to a transmission. The method and apparatus may acquire other CoMP related information. The method and apparatus may apply to non-transparent CoMP scenarios.
