Embodiment Construction
[0021] Some embodiments of the present invention will now be introduced in detail, and these examples will be described in conjunction with the accompanying drawings.
[0022] figure 1 is a schematic diagram of multi-level beams for achieving spatial diversity in a beamformed mobile communication network 100 according to a novel aspect. The beamforming millimeter wave mobile communication network 100 includes a base station eNB 101 and a user equipment UE 102 . In a Long Term Evolution (LTE) system, there are many handover scenarios and schemes, including intra-macro cell handover, intra-small cell handover, heterogeneous network (HetNet) and cross-system handover. In general, the mobility of LTE small cells can be used as a baseline for standalone mmWave small cells. However, the heavy reliance on directional transmission and the fragility of the propagation environment present unique challenges arising from channel characteristics and beamforming in mmWave small cells.
