摘要

在智能电网中,无线通信网络中存在大量的用户设备(ue),存在外部干扰。本文提出了一种基于簇跳和子带跳的快速调度机制。集群中的所有终端都被分配到子带中相对位置固定的资源块(Resource Block),并根据重新调度的集群子带切换工作通道。设计了一种利用相邻簇头分配子带的改进方案,避免了未检测到的外部干扰问题。仿真结果表明,提出的抗干扰方案显著降低了信令开销,增强方案能进一步提高系统性能。

Pre-scheduling and sub-band hopping in smart grid
There are large number of UEs (User Equipment) in the wireless communication networks for power distribution in smart grid with external interference. Based on cluster and sub-band hopping, a fast scheduling mechanism is proposed in this paper. All UEs in the cluster are assigned to the RBs (Resource Block) with fixed relative position in the sub-band, and their working channels are switched according to their re-scheduled cluster sub-band. A further enhanced proposal is also designed which assigned the sub-band with the help of adjacent cluster heads to avoid the problem of undetected external interference. The simulation results show that the proposed interference avoiding scheme dramatically reducing the cost of signaling overhead and the enhanced proposal can further improve the system performance.
