| 摘 要： | 鉴于超密集网络中急剧增长的小区和用户数量,研究了如何通过合理地选择联合传输用户来实现动态干扰协调,以此提高小区边缘用户频谱效率。通过动态协作簇划分和动态联合静默传输2种手段,将所有用户分类;再利用迭代优化算法进一步提高系统性能,同时解决了联合传输用户的数量选择问题。仿真结果表明,与传统的协作多点方案相比,所提方案在不损失小区平均频谱效率的前提下,在小区边缘频谱效率方面存在显著的性能增益。

| Abstract: | In consideration of the rapidly increasing number of cells and users in the ultra-dense network,how to realize dynamic interference coordination by selecting the appropriate joint transmission users was studied,so as to improve the spectral efficiency of the edge users.All users were classified by dynamic coordination cluster division and dynamic joint-muting transmission.The iterative optimization algorithm was used to further improve the system performance and solve the problem of selecting the number of joint transmission users.The simulation results prove that compared with the conventional CoMP JT scheme,the proposed scheme has significant performance gains in the cell edge spectral efficiency without reducing the cell average spectral efficiency. |
