초록
This letter proposes an enhanced inter-beam handover (IBH) scheme for millimeter-wave mobile communication systems. The proposed scheme adopts an inter-beam coordinated scheduling to improve the performance of the IBH which can be seriously deteriorated. In addition, the proposed scheme exploits the small-sized low layer messages to reduce the signaling overhead for the IBH by considering the main features of the IBH. Numerical results have shown that the proposed scheme can decrease the handover failure rate and reduce the signaling overhead by 78% 92% compared with the conventional scheme.
