    Abstract: A user equipment UE has a c-plane connection to a macro cell and a u-plane connection to a source local cell. The u-plane connection is handed over to a target local cell while maintaining the c-plane connection so the macro cell can facilitate the u-plane handover. In one embodiment the UE uses coverage information about the source local cell and its own mobility to predict when the handover is needed, and the macro cell can identify which is the target local cell. The handover can occur across a coverage gap between the source and target local cells, where the UE gets synchronization information and a dedicated preamble for the target local cell prior to being in its range. In the examples also path switching and transfer of the UE context can occur prior to the UE being in range of the target local cell.

    Abstract translation: 用户设备UE具有到宏小区的c平面连接和到源本地小区的u平面连接。 u平面连接被切换到目标本地小区，同时保持c平面连接，因此宏小区可以方便u平面切换。 在一个实施例中，UE使用关于源本地小区及其自身的移动性的覆盖信息来预测何时需要切换，并且宏小区可以识别哪个是目标本地小区。 切换可以在源和目标本地小区之间的覆盖间隙发生，其中UE在其范围内获得同步信息和目标本地小区的专用前同步码。 在示例中，UE上下文的路径切换和传送可以在UE处于目标本地小区的范围之前发生。

    Abstract: A method, apparatus and computer program product are provided to collect a channel information in conjunction with wireless communications; estimate at least one of a line of sight traffic and a non-line of sight traffic on the channel based on channel information; and select, with a processor, a frequency band, wherein the frequency band includes at least a respective frequency or frequency range and a frequency band or plurality of frequency bands and a bandwidth for the respective frequency or frequency range and time allocation for the frequency or frequency range. The selection is based on the estimated line of sight and non-line of sight traffic, wherein the respective frequency band comprises selecting at least one of a first frequency band or a second frequency band with the first and second frequency bands being different from one another.
