小区中断补偿是自管理网络的关键技术，旨在自动缓解无线网络中由于意外故障而发生的中断。然而，很少有详细的机制来自动补偿中断小区的覆盖空洞。本文提出了一种基于导频功率调整的无线接入网功率补偿机制。它通过自动调整周围小区的导频功率来补偿覆盖空洞，以最大可能程度地满足运营商基于覆盖和容量的性能要求。实验结果表明，该机制是可行的和有效的。该算法能够在不产生导频污染的情况下，有效地自动补偿中断小区的覆盖范围，并尽可能减少对服务质量的影响。
Cell outage compensation is the key technology of self-managed network, which aims to automatically mitigate outages that occur in radio networks due to unexpected failures. However, there are few detailed mechanisms to automatically compensate the coverage hole of the outage cell. In this paper, an adjusting pilot power based mechanism of compensation in wireless access network is presented. It compensates the coverage hole by automatic adjustment of pilot power in surrounding cells in order to meet the operator's performance requirements based on coverage and capacity to the largest possible extent. The experiment results show that the proposed mechanism is feasible and efficient. It could effectively and automatically compensate the coverage of cell in outage without pilot pollution, and impair the QoS as little as possible.
