【摘要】：为解决由宏基站和微微基站构成的两层异构网络中存在的下行链路干扰问题,提出一种基于用户划分的资源分配算法,并根据资源分配策略进行功率控制。通过信干噪比的门限值,将用户分为正常用户和边缘用户,分配频带资源,在宏小区边缘用户所在的频带范围内,动态地调整干扰基站的发射功率,减小宏小区用户的跨层干扰。仿真结果表明,与现有方案相比,所提算法能够有效抑制干扰并提高系统的吞吐量。
[Abstract]:In order to solve the downlink interference problem in two layers of heterogeneous networks composed of macro base station and pico base station, a resource allocation algorithm based on user partition is proposed, and power control is carried out according to resource allocation strategy. Through the threshold value of signal-to-noise ratio, the users are divided into normal users and edge users, and the frequency band resources are allocated to dynamically adjust the transmission power of the interference base station within the range of the band in which the edge users of the macro cell are located. Reduce cross-layer interference of macro cell users. The simulation results show that the proposed algorithm can effectively suppress interference and improve the throughput of the system.
