The spatial dynamic spectrum allocation in heterogeneous wireless city environment, relates to a spatial dynamic spectrum allocation method, dynamic spectrum dynamic spectrum allocation method to solve the space of the existing distribution of poor real-time problems. Methods: according to the city of heterogeneous wireless network within the coverage area of the spectrum demand distribution threshold, and the division of regional hot and non hot region; then according to the distribution of demand spectrum space, uniform spectrum allocation, meet the minimum spectrum demand non hotspot, the remaining spectrum demand of each cell in the hot zone and then calculation, calculation the remaining spectrum number according to the number of total and spectrum allocated for each spectrum, hot spots in the cell as a parallel independent space dynamic spectrum allocation granularity. The invention is applicable to the spatial dynamic spectrum allocation in the urban heterogeneous wireless environment.

１．城市异构无线环境下的空间动态频谱分配方法，其特征是：它由以下步骤实现：步骤一、根据城市异构无线网络覆盖区域内的频谱需求空间分布选取门限ｄ０；对于城市异构无线网络覆盖区域内的每个小区：如果该小区的频谱需求总量大于或等于所述门限ｄ０，则将该小区划分为Ｍ个相互不相邻的热点区域；如果该小区的频谱需求总量小于所述门限ｄ０，则将该小区定义为非热点区域；Ｍ为正整数；步骤二、根据城市异构无线网络覆盖区域内的频谱需求空间分布，在整个覆盖区域内采用均匀的频谱分配方法来进行频谱分配，满足非热点区域的最低频谱需求，然后计算热点区域中各小区的剩余频谱需求；步骤三、根据频谱总数ＳＰｔｏｔａｌ和已分...
